Walkthrough

Replaces the Service Registry with Service Registry V2: on‑chain ID‑based ServiceOnChain plus IPFS‑backed off‑chain metadata, full CRUD/lifecycle/agent APIs, Zod schemas/validation, optional IPFS integration, signer-aware write operations, expanded SDK exports/types/errors, updated contracts/ABIs, and removed TaskRegistry and its deployment/tests.

Changes

Cohort / File(s)	Summary
Product requirements .taskmaster/docs/prd.txt	Adds PRD for Service Registry V2: hybrid on‑chain/off‑chain model, agent assignment, lifecycle governance, advanced discovery, Agent/Task registry requirements, SDK/CLI/REST expectations.
Task tracking .taskmaster/tasks/tasks.json	Adds Task 25 (Service Management System V2) and Task 26 (Refactor to Service‑Based API Architecture); updates timestamp and subtasks.
SDK public surface packages/sdk/src/ensemble.ts, packages/sdk/src/index.ts, packages/sdk/src/types.ts	Expands Ensemble public API to typed service CRUD (RegisterServiceParams/UpdateServiceParams/ServiceRecord), exposes services getter; re-exports base/service schemas and validation utilities; consolidates service types.

Poem

I hopped through schemas, zippy and bright,
Packed metadata carrots, all validated right.
IPFS clouds hid the crunchy keys,
On‑chain burrows hummed with tidy IDs.
Assign an agent — thump! — and off we go 🥕

35-55: Normalize Eliza params output type; make connectionUrl guaranteed post-transform.

Currently both connectionUrl and websocketUrl are optional in the static type even after transform/refine, which is error-prone at call sites.

Apply:

-export const ElizaParamsSchema = z.object({
-  connectionUrl: z.string().url('Invalid connection URL').optional(),
-  websocketUrl: z.string().url('Invalid websocket URL').optional(), // Deprecated, for backward compatibility
-  agentId: z.string().min(1, 'Agent ID is required'),
-  version: z.enum(['0.x', '1.x']),
-  env: z.enum(['production', 'dev'])
-}).transform((data) => {
-  // Handle backward compatibility: migrate websocketUrl to connectionUrl
-  if (data.websocketUrl && !data.connectionUrl) {
-    const { websocketUrl, ...rest } = data;
-    return { ...rest, connectionUrl: websocketUrl };
-  }
-  // Remove websocketUrl if connectionUrl exists
-  if (data.connectionUrl && data.websocketUrl) {
-    const { websocketUrl, ...rest } = data;
-    return rest;
-  }
-  return data;
-}).refine((data) => data.connectionUrl, {
-  message: 'Either connectionUrl or websocketUrl (deprecated) is required'
-});
+const ElizaRaw = z.object({
+  connectionUrl: z.string().url('Invalid connection URL').optional(),
+  websocketUrl: z.string().url('Invalid websocket URL').optional(), // deprecated
+  agentId: z.string().min(1, 'Agent ID is required'),
+  version: z.enum(['0.x', '1.x']),
+  env: z.enum(['production', 'dev'])
+}).superRefine((data, ctx) => {
+  if (!data.connectionUrl && !data.websocketUrl) {
+    ctx.addIssue({ code: z.ZodIssueCode.custom, message: 'Either connectionUrl or websocketUrl (deprecated) is required', path: ['connectionUrl'] });
+  }
+});
+

123-134: Agent metadata imageURI lacks validation; align with AgentRecord.

imageURI is a plain string here but validated elsewhere; enforce the same URL/IPFS constraint.

-export const AgentMetadataSchema = z.object({
+export const AgentMetadataSchema = z.object({
   name: z.string(),
   description: z.string(),

🧹 Nitpick comments (12)

packages/sdk/src/errors.ts (1)

36-70: Solid addition of service-specific errors; consider a typed validation payload and a common base.

• Prefer typing validationErrors to Zod issues to improve DX.
• Optional: introduce a ServiceError base to unify catch logic and set prototype once.

Apply within-file diffs:

+import type { ZodIssue } from "zod";
@@
-export class ServiceValidationError extends Error {
-  constructor(message: string, public readonly validationErrors?: any) {
+export class ServiceValidationError extends Error {
+  constructor(message: string, public readonly validationErrors?: readonly ZodIssue[]) {
     super(`Service validation failed: ${message}`);
     this.name = "ServiceValidationError";
   }
 }

Outside selected lines (example implementation for a base error):

// Consider placing near the top of the service error section
export class ServiceError extends Error {
  constructor(message: string) {
    super(message);
    this.name = "ServiceError";
    Object.setPrototypeOf(this, new.target.prototype);
  }
}
// Then extend ServiceError instead of Error for the V2 errors

If you prefer not adding a base, at least add:
Object.setPrototypeOf(this, new.target.prototype); in each constructor to preserve instanceof across transpilation targets.

packages/sdk/src/types.ts (1)

85-100: Add JSDoc @deprecated to the Service alias in service.schemas.ts

It looks like the Service alias is defined without a JSDoc deprecation tag, so IDEs (and downstream consumers) won’t automatically flag its use as deprecated. Please update the definition in
packages/sdk/src/schemas/service.schemas.ts around line 209 to something like:

/**
 * @deprecated Use `ServiceRecord` directly instead.
 * Legacy alias retained for backwards compatibility.
 */
export type Service = ServiceRecord;

This will ensure that when you re-export Service (as in packages/sdk/src/types.ts), the deprecation notice carries through in IDEs and documentation tools.

.taskmaster/docs/prd.txt (1)

31-48: Clarify service identity and lookup semantics.

Specify the canonical identifier used across SDK/CLI/contracts (e.g., serviceId UUID vs name), and whether getService() is by id or name. This avoids ambiguity when names collide and aligns schemas with CLI UX.

If the SDK currently exposes getService(name: string), consider adding getServiceById(id: string) and reflecting that here for consistency.

packages/sdk/src/schemas/agent.schemas.ts (2)

101-108: Deduplicate and harden URI validation via a shared schema.

You repeat manual protocol checks for agentUri/imageURI. Prefer a shared HttpOrIpfsUrlSchema from base.schemas to ensure consistency and reuse.

After adding HttpOrIpfsUrlSchema in base.schemas.ts (see that file’s comment), use:

-import { 
-  ethereumAddressRegex, 
-  BigNumberishSchema, 
-  EthereumAddressSchema,
-  URLSchema 
-} from './base.schemas';
+import { 
+  ethereumAddressRegex, 
+  BigNumberishSchema, 
+  HttpOrIpfsUrlSchema 
+} from './base.schemas';

-  agentUri: z.string().refine(
-    (val) => val.startsWith('http://') || val.startsWith('https://') || val.startsWith('ipfs://'),
-    'URI must be a valid HTTP(S) URL or IPFS URI'
-  ),
-  imageURI: z.string().refine(
-    (val) => val.startsWith('http://') || val.startsWith('https://') || val.startsWith('ipfs://'),
-    'Image URI must be a valid HTTP(S) URL or IPFS URI'
-  ),
+  agentUri: HttpOrIpfsUrlSchema,
+  imageURI: HttpOrIpfsUrlSchema,

And similarly in RegisterAgentParamsSchema.imageURI.

Also applies to: 147-150

---

115-117: BigNumberish for reputation/totalRatings is too loose for counts.

Counts/ratings typically require non-negative integers; BigNumberish (esp. strings) weakens validation.

-  reputation: BigNumberishSchema,
-  totalRatings: BigNumberishSchema,
+  reputation: z.number().min(0),
+  totalRatings: z.number().int().min(0),

If on-chain numeric strings are needed, consider a separate IntegerLike schema instead of the global BigNumberish (see base.schemas.ts comment).

packages/sdk/src/index.ts (1)

25-43: Missing semicolon after export block.

Keep statement termination consistent; avoids diffs churn with formatters.

 } from "./schemas/service.schemas"
+;

packages/sdk/src/schemas/service.schemas.ts (1)

91-95: endpointSchema naming is misleading.

This field holds a URL, not a JSON Schema. Consider renaming to endpointUrl to avoid confusion.

No code change required if you prefer to keep the current name; just ensure docs clarify it.

packages/sdk/src/services/ServiceRegistryService.ts (5)

61-66: Doc return type mismatches (Service vs ServiceRecord).

JSDoc says Promise, but the method returns ServiceRecord. Update for accuracy and IDE help.

- * @returns {Promise<Service>} The registered service with generated ID and metadata
+ * @returns {Promise<ServiceRecord>} The registered service with generated ID and metadata

Apply similarly to other methods returning ServiceRecord.

---

127-135: Post-registration validation is good. Consider parsing (not just safeParse) for strong guarantees.

Current approach is fine; optionally use parseServiceRecord to throw with structured ZodError for uniform error handling.

-      const serviceValidation = validateServiceRecord(serviceRecord);
-      if (!serviceValidation.success) {
-        throw new ServiceValidationError(
-          "Service validation failed after blockchain registration",
-          serviceValidation.error.issues
-        );
-      }
+      // Strongly assert validity, let callers format via formatServiceValidationError if needed
+      parseServiceRecord(serviceRecord);

---

664-692: Legacy getService: avoid crypto.randomUUID portability issues.

Global crypto.randomUUID is not universally available in Node. Prefer Node’s crypto import or a uuid lib.

-      id: crypto.randomUUID(), // Placeholder - should come from contract
+      id: (globalThis.crypto?.randomUUID?.() ?? require('crypto').randomUUID?.() ?? Math.random().toString(36).slice(2)),

Or import { randomUUID } from 'crypto' at top-level when targeting Node only.

---

138-144: Fragile revert detection; don’t rely on exact error.reason string.

Contract revert reasons vary. Prefer matching error codes or parsing error data.

-      if (error.reason === "Service already registered") {
+      if (typeof error?.reason === 'string' && /already\s+registered/i.test(error.reason)) {
         throw new ServiceAlreadyRegisteredError(parsedParams.name);
       }

Longer-term: derive and match custom errors from the ABI where possible.

---

334-345: Console logging in SDKs can be noisy; inject a logger or use debug.

Consider a pluggable logger or a noop-able debug channel to avoid polluting consumer logs.

No code diff required; optional ergonomics improvement.

8-8: registerService signature migration: call sites verified, docs/examples need manual review

All existing call sites now use the single-object signature (registerService(params: RegisterServiceParams)) and there are no remaining legacy positional calls. However, no documentation or example files reference registerService, so please confirm any README, markdown guides, or TS examples have been updated to reflect this change.

• Call sites verified
– packages/sdk/test/ensemble.test.ts (lines 201, 218): await sdk.registerService(service)
– packages/sdk/scripts/register-services.ts (line 9): await ensemble.registerService(service)

• SDK implementation
– packages/sdk/src/ensemble.ts (lines 273–276): new signature and delegation to ServiceRegistryService.registerService(params)
– packages/sdk/src/services/ServiceRegistryService.ts (line 67): accepts RegisterServiceParams
– Legacy registerServiceLegacy() remains deprecated (lines 631–636)

• Documentation check
– No matches for “registerService” in .md, .ts, or .tsx files outside src/ – please manually verify any external docs/examples

Next steps

1. Manually review and update any user-facing documentation or sample code to use the new object-param signature.
2. Add an @remarks block on the registerService method in packages/sdk/src/ensemble.ts (around lines 273–276) to note the signature change and link to the RegisterServiceParams schema for discoverability.

71-83: Agent type re-exports centralization looks good.

No issues spotted.

packages/sdk/src/schemas/agent.schemas.ts (1)

9-10: No circular import detected between agent.schemas.ts and service.schemas.ts

Verification steps confirmed that:

• agent.schemas.ts re-exports service.schemas.ts;
• service.schemas.ts does not import or re-export agent.schemas.ts;
• base.schemas.ts has no references to either schema;
• both packages/sdk/index.ts and packages/sdk/src/index.ts simply re-export the schemas without introducing cycles.

You can safely keep the barrel export as is.

packages/sdk/src/index.ts (1)

10-12: Good call exposing base schemas at the top-level.

This helps downstreams reuse validators (addresses, UUID, URLs) without deep imports.

packages/sdk/src/schemas/service.schemas.ts (2)

128-145: Published-without-agent rule is great.

This catches a common misconfiguration early.

387-394: Nice error formatting helper.

User-facing formatting is helpful for CLI/SDK consumers.

Missing V2 Surface in SDK — Critical Implementations Required

The repo-level verification shows that several V2 features outlined in .taskmaster/tasks/tasks.json are not yet present in the SDK. Before merging, the following must be added:

• In packages/sdk/src/services/ServiceRegistryService.ts
 – createService(...)
 – assignAgent(...), unassignAgent(...)
 – getAssignedAgents(...)
 – transferOwnership(...)

• Barrel exports (e.g. packages/sdk/src/index.ts or packages/sdk/src/types.ts) must re-export the service schemas and types from schemas/service.schemas.ts.

• Define and throw the new error classes referenced in the V2 spec (e.g. ServiceNotFoundError, ServiceOwnershipError, ServiceStatusError, ServiceValidationError, ServiceAgentAssignmentError).

• Add CLI stubs and command group under ensemble services with the subcommands: create, list, get, update, delete, assign, unassign, transfer.

Optional refactor: consider enriching each subtask with explicit acceptance criteria (inputs, outputs, and preconditions) to strengthen traceability from PRD → code → tests.

🤖 Prompt for AI Agents

In .taskmaster/tasks/tasks.json around lines 334 to 402, the task outlines V2
SDK work but the SDK is missing the required surface; implement the following:
add createService(), assignAgent(), unassignAgent(), getAssignedAgents(),
transferOwnership() (and related CRUD/status methods if not present) to
packages/sdk/src/services/ServiceRegistryService.ts with proper validation and
error handling; add barrel exports in packages/sdk/src/index.ts (or types.ts) to
re-export service schemas and types from
packages/sdk/src/schemas/service.schemas.ts; create and export the new error
classes ServiceNotFoundError, ServiceOwnershipError, ServiceStatusError,
ServiceValidationError, ServiceAgentAssignmentError in the SDK error module and
update usages; and add CLI command stubs under the ensemble services group with
subcommands create, list, get, update, delete, assign, unassign, transfer so the
commands wire to the new service methods.

⚠️ Potential issue

BigNumberishSchema accepts any string (validation bypass). Tighten to numeric/hex strings.

As written, "hello" passes, defeating schema guarantees wherever BigNumberish is used (e.g., pricing).

-export const BigNumberishSchema = z.union([
-  z.bigint(),
-  z.string(),
-  z.number()
-]);
+export const BigNumberishSchema = z.union([
+  z.bigint(),
+  // Integers or decimals, or 0x-hex. Trim and forbid whitespace-only.
+  z.string()
+    .trim()
+    .regex(/^(0x[0-9a-fA-F]+|\d+(\.\d+)?)$/, 'Must be a numeric or 0x-hex string'),

Deletion policy conflicts with transition table; make them consistent and include serviceId in errors.

+  private validateStatusTransition(serviceId: string, currentStatus: ServiceStatus, newStatus: ServiceStatus): void {
     const validTransitions: Record<ServiceStatus, ServiceStatus[]> = {

+      'published': ['archived'], // forbid direct delete from published
       'archived': ['published', 'deleted'],  // Allow reactivation from archive
       'deleted': [] // No transitions from deleted state
     };
     
     const allowedTransitions = validTransitions[currentStatus] || [];
     if (!allowedTransitions.includes(newStatus)) {
-      throw new ServiceStatusError(
-        "unknown", 
-        currentStatus, 
-        `Cannot transition from ${currentStatus} to ${newStatus}. Allowed: ${allowedTransitions.join(', ')}`
-      );
+      throw new ServiceStatusError(serviceId, currentStatus, allowedTransitions.join(' or ') || 'n/a');
     }
   }

And adjust callers:

-  this.validateStatusTransition(service.status, status);
+  this.validateStatusTransition(serviceId, service.status, status);

deleteService then aligns with the table (published → archived first).

281-285: Name-based getService conflicts with PRD’s ID-based doc; suggest adding getServiceById and deprecating name lookup.

Name collisions are likely in a marketplace. Keep this for DX, but add an ID-based variant.

Proposed follow-up: add getServiceById(id: string): Promise<ServiceRecord> to Ensemble and ServiceRegistryService, and update docs/tests accordingly. I can open an issue and draft the change. Do you want that?

62-71: Provider fallback ignores configured rpcUrl.

When no signer/provider is supplied, prefer config.network.rpcUrl over default JsonRpcProvider.

-    const provider = signerOrProvider || new ethers.JsonRpcProvider();
+    const provider =
+      signerOrProvider ||
+      new ethers.JsonRpcProvider(
+        (config as any)?.network?.rpcUrl ?? undefined
+      );

46-50: Propagate signer to all write-capable services.

You update agents and serviceRegistry services; if TaskService ever performs writes directly, consider a setSigner there too. If not applicable, ignore.

---

224-230: Minor JSDoc param name mismatch.

Doc says agentAddress; param is agentId. Align naming for clarity.

-   * @param {string} agentAddress - The address of the agent.
+   * @param {string} agentId - The address of the agent.

CLAUDE.md (1)

176-181: PRD pointer addition LGTM.

Clear, actionable, and aligned with our learnings about running task-master from project root.

packages/sdk/scripts/data/servicesList.ts (2)

1-4: Type migration to RegisterServiceParams[] looks correct.

Import and exported type align with the V2 schemas.

---

6-13: I've added scripts to:

• Locate and inspect the ServiceMetadataSchema definition and its endpointSchema field.
• Confirm the presence and form of ServiceMethod and ServiceCategory in the types.

Once we have these outputs, we can accurately determine whether to rename endpointSchema or adjust the type/schema alignment and finalize the refactoring recommendation.

packages/sdk/test/ensemble.test.ts (2)

225-260: Duplicate-registration path looks good.

Resolved then rejected sequencing correctly simulates “first ok, second dup”.

---

525-541: Signer guard test for registerService is solid.

Confirms the new requireSigner path.

packages/sdk/src/ensemble.ts (1)

8-13: Type surface changes LGTM.

Importing RegisterServiceParams and returning ServiceRecord aligns with V2.

606-607: Use interface.getEventTopic for better compatibility with ethers v6.

101-101: Cross-platform base64 encoding needed for browser compatibility.

The direct use of Node.js Buffer will fail in browser environments. Implement a cross-platform solution for base64 encoding.

Apply this diff to add browser-safe base64 encoding:

-        serviceUri = `data:application/json;base64,${Buffer.from(JSON.stringify(metadataWithTimestamps)).toString('base64')}`;
+        const json = JSON.stringify(metadataWithTimestamps);
+        const toBase64 = () => {
+          if (typeof Buffer !== 'undefined') {
+            return Buffer.from(json, 'utf-8').toString('base64');
+          }
+          // Browser-safe UTF-8 → base64
+          const bytes = new TextEncoder().encode(json);
+          let bin = '';
+          for (let i = 0; i < bytes.length; i++) {
+            bin += String.fromCharCode(bytes[i]);
+          }
+          return btoa(bin);
+        };
+        serviceUri = `data:application/json;base64,${toBase64()}`;

This same pattern should be applied to line 233 as well.

163-172: Status updates via updateService bypass transition validation.

When the update includes a status change, the transition isn't validated against the current status, potentially violating lifecycle rules.

Apply this diff to validate status transitions:

 const parsedUpdates = parseUpdateServiceParams({ ...updates, id: serviceId });
 
 try {
   // Get current service
   const currentService = await this.getServiceById(serviceId);
   
   // Check ownership
   await this.verifyServiceOwnership(currentService, await this.signer!.getAddress());
+  
+  // Validate status transition if status is being updated
+  if (parsedUpdates.status && parsedUpdates.status !== currentService.status) {
+    this.validateStatusTransition(serviceId, currentService.status, parsedUpdates.status);
+  }

---

298-315: getServiceById is unimplemented, causing all management operations to fail.

The placeholder implementation throws an error, which makes all operations that depend on it (update, delete, transfer, status changes, agent management) unusable. This should be clearly marked as not yet supported.

Consider adding clear NotImplementedError handling and documentation:

+export class ServiceNotImplementedError extends Error {
+  constructor(feature: string) {
+    super(`Feature not yet implemented: ${feature} requires ServiceRegistry V2 contract support`);
+    this.name = "ServiceNotImplementedError";
+  }
+}

 async getServiceById(serviceId: string): Promise<ServiceRecord> {
   try {
-    // This is a placeholder implementation - will need smart contract support
-    // For now, falling back to the existing getService method
     console.log(`Getting service by ID: ${serviceId}`);
-    
-    // In a real implementation, this would query by service ID
-    // For now, we'll need to implement a mapping system
-    throw new Error("getServiceById not yet implemented - requires smart contract V2");
+    throw new ServiceNotImplementedError("getServiceById");
   } catch (error: any) {
     console.error(`Error getting service ${serviceId}:`, error);
-    if (error.message.includes("not found") || error.message.includes("does not exist")) {
+    if (error instanceof ServiceNotImplementedError) {
+      throw error;
+    } else if (error.message.includes("not found") || error.message.includes("does not exist")) {
       throw new ServiceNotFoundError(serviceId);
     }
     throw error;
   }
 }

Also consider guarding dependent methods to provide a better developer experience until the read API is implemented.

652-668: Status transition validation inconsistent with deletion logic.

The validateStatusTransition allows 'published' → 'deleted', but deleteService at line 271-276 forbids deletion of published services. Additionally, ServiceStatusError is constructed with "unknown" serviceId instead of the actual ID.

Apply this diff to fix the inconsistency:

-  private validateStatusTransition(currentStatus: ServiceStatus, newStatus: ServiceStatus): void {
+  private validateStatusTransition(serviceId: string, currentStatus: ServiceStatus, newStatus: ServiceStatus): void {
     const validTransitions: Record<ServiceStatus, ServiceStatus[]> = {
       'draft': ['published', 'deleted'],
-      'published': ['archived', 'deleted'],
+      'published': ['archived'], // Require archiving before deletion
       'archived': ['published', 'deleted'],  // Allow reactivation from archive
       'deleted': [] // No transitions from deleted state
     };
     
     const allowedTransitions = validTransitions[currentStatus] || [];
     if (!allowedTransitions.includes(newStatus)) {
       throw new ServiceStatusError(
-        "unknown", 
+        serviceId, 
         currentStatus, 
-        `Cannot transition from ${currentStatus} to ${newStatus}. Allowed: ${allowedTransitions.join(', ')}`
+        allowedTransitions.join(' or ') || 'none'
       );
     }
   }

Also update the caller at line 423:

-      this.validateStatusTransition(service.status, status);
+      this.validateStatusTransition(serviceId, service.status, status);

packages/sdk/src/schemas/service.schemas.ts (2)

54-59: Add pricing model invariants validation.

The schema allows optional price/tokenAddress for all models, but paid models should require these fields while free models should forbid them.

Apply this refinement to enforce pricing invariants:

 export const ServicePricingSchema = z.object({
   model: ServicePricingModelSchema,
   price: BigNumberishSchema.optional(), // Optional for free services
   tokenAddress: z.string().regex(ethereumAddressRegex).optional(),
   freeQuota: z.number().int().min(0).optional() // Free calls before charging
-});
+}).refine(
+  (data) => {
+    if (data.model === 'free') {
+      return !data.price && !data.tokenAddress;
+    } else {
+      return data.price !== undefined && data.tokenAddress !== undefined;
+    }
+  },
+  (data) => ({
+    message: data.model === 'free' 
+      ? 'Free services should not have price or tokenAddress' 
+      : 'Paid services require both price and tokenAddress'
+  })
+);

---

70-77: ServiceOnChain schema needs stricter validation.

The id field should enforce non-empty values, and serviceUri should validate URI schemes to match the expected formats (IPFS, data URIs, HTTP(S)).

Apply this diff to add proper validation:

 export const ServiceOnChainSchema = z.object({
-  id: z.string().describe('Auto-incremented service ID from blockchain'),
+  id: z.string().min(1, 'Service ID is required').describe('Auto-incremented service ID from blockchain'),
   owner: EthereumAddressSchema,
   agentAddress: z.string().regex(ethereumAddressRegex, 'Invalid agent address format').optional(),
-  serviceUri: z.string().describe('IPFS URI for service metadata'),
+  serviceUri: z.string().refine(
+    (v) => v.startsWith('ipfs://') || v.startsWith('data:') || v.startsWith('http://') || v.startsWith('https://'),
+    'Service URI must be ipfs://, data:, or HTTP(S)'
+  ).describe('URI for service metadata'),
   status: ServiceStatusSchema,
   version: z.number().int().min(0).describe('Version for cache invalidation')
 });

🧹 Nitpick comments (3)

packages/sdk/src/services/ServiceRegistryService.ts (1)

539-542: Status validation for unassignAgentFromService is too restrictive.

The validation only allows 'draft' or 'archived' status, but the contract expects numeric values (0 or 2). Consider using an enum or constants for clarity.

Consider defining status constants for better maintainability:

+// Add at the top of the class
+private readonly STATUS_MAPPING = {
+  'draft': 0,
+  'published': 1,
+  'archived': 2,
+  'deleted': 3
+} as const;

 // Validate status parameter
 if (newStatus !== 'draft' && newStatus !== 'archived') {
   throw new ServiceValidationError('Status must be either "draft" or "archived"');
 }
 
 // Later in the code (line 564):
-        newStatus === 'draft' ? 0 : 2 // DRAFT = 0, ARCHIVED = 2
+        this.STATUS_MAPPING[newStatus]

packages/contracts/contracts/ServiceRegistryUpgradeable.sol (2)

338-347: Consider gas optimization for array removal operations.

The _removeFromOwnerServices and _removeFromAgentServices functions use linear search which can be expensive for large arrays. Consider tracking indices or using a different data structure for O(1) removal.

For frequently modified arrays, consider maintaining a mapping of serviceId to array index:

mapping(address => mapping(uint256 => uint256)) private ownerServiceIndex;
mapping(address => mapping(uint256 => uint256)) private agentServiceIndex;

This would allow O(1) removal at the cost of additional storage for the index mappings. The trade-off is worthwhile for users with many services.

Also applies to: 354-363

---

59-61: Initialization values are redundant.

Setting nextServiceId and totalServices to 0 is unnecessary as storage variables default to 0.

 function initialize() public initializer {
     __Ownable_init(msg.sender);
     __UUPSUpgradeable_init();
-    nextServiceId = 0;
-    totalServices = 0;
 }

packages/contracts/contracts/AgentsRegistryUpgradeable.sol (1)

152-154: Removed combined agent-service registration method

The V2 architecture separates agent and service management as intended. This removal aligns with the Service Registry V2's independent lifecycle management model.

.taskmaster/tasks/tasks.json (1)

334-402: V2 task comprehensively defined with clear subtask structure

The Service Management System V2 task is well-structured with clear dependencies and subtasks. The architecture aligns perfectly with the Service Registry V2 implementation.

packages/sdk/test/ensemble.test.ts (3)

196-227: Service registration test correctly uses V2 metadata structure

The test properly validates the new V2 service registration with nested metadata and returns the complete ServiceRecord.

---

266-291: New V2 service methods properly tested

Good coverage of the new getServiceById method with proper assertions on the returned ServiceRecord structure.

---

337-387: Comprehensive listServices test with proper filtering

Excellent test coverage for the new listServices method including various filter combinations and proper ServiceRecord array validation.

packages/sdk/src/ensemble.ts (3)

47-49: Service registry getter properly exposes V2 functionality

The new services getter provides clean access to the ServiceRegistryService instance, enabling direct use of V2-specific methods.

---

282-285: Service registration correctly uses RegisterServiceParams

The method signature and implementation properly align with the V2 service registration pattern using RegisterServiceParams.

---

301-348: V2 service methods comprehensive and well-documented

The new service methods (getServiceById, updateService, deleteService, listServices) provide a complete V2 API surface with proper JSDoc documentation and type safety.

.taskmaster/docs/prd.txt (3)

31-60: Service Registry V2 requirements comprehensively documented

The PRD properly documents the hybrid on-chain/off-chain architecture with clear separation of concerns between blockchain and IPFS storage. The service-agent assignment model (REQ-1.3) and advanced discovery features (REQ-1.4) align well with the implementation.

---

153-182: ServiceRegistryService API requirements match implementation

REQ-4.1.2 accurately describes the implemented service registry APIs including registerService, getService, updateService, getAllServices, and activateService with proper IPFS integration.

---

183-213: Three-schema architecture properly specified

REQ-4.1.3 clearly defines the three-schema architecture (ServiceOnChainSchema, ServiceMetadataSchema, ServiceRecordSchema) and the 4-state lifecycle model, which aligns with the actual implementation.

packages/sdk/src/abi/ServiceRegistry.json (1)

1-730: LGTM! Comprehensive V2 contract interface.

The ABI properly reflects the V2 service registry architecture with:

• ID-based service management
• Comprehensive lifecycle operations
• Agent assignment functionality
• Proper event definitions for state changes
• UUPS upgradeability support

packages/contracts/contracts/ServiceRegistryUpgradeable.sol (2)

17-21: ServiceStatus enum values well-defined.

The lifecycle states (DRAFT, PUBLISHED, ARCHIVED, DELETED) provide clear service state management with appropriate transitions enforced.

---

87-116: registerService implementation is robust.

The function properly:

• Auto-increments service IDs
• Initializes service with DRAFT status
• Updates all necessary mappings
• Emits appropriate events

packages/sdk/src/schemas/service.schemas.ts (2)

136-147: Published service validation is good!

The refinement correctly enforces that published services must have a non-zero agent address, maintaining data integrity.

---

292-306: Enhanced error messages in parseRegisterServiceParams.

Good practice to prefix error messages with context ("Service registration:") for better debugging experience.

Implement missing ServiceRegistryService V2 methods

• ServiceRegistryService.ts (packages/sdk/src/services/ServiceRegistryService.ts) is missing createService(...) and transferOwnership(...) implementations.
• listServices(...) currently only logs “not yet fully implemented” – replace the placeholder warning with full V2 logic.

🤖 Prompt for AI Agents

In .taskmaster/tasks/tasks.json around lines 349 to 356, the task entry
documents that packages/sdk/src/services/ServiceRegistryService.ts is missing
implementations for createService(...) and transferOwnership(...), and
listServices(...) contains only a placeholder log; implement the full V2 logic
by adding createService to validate inputs, construct and persist the new
service entity (including status, owner, metadata, timestamps), integrate with
existing registry/storage and any blockchain call shims with proper error
handling and unit-test hooks; implement transferOwnership to verify permissions,
validate new owner, update ownership atomically, emit events/audit logs and
handle blockchain interactions and rollback on failure; replace the listServices
placeholder with a real V2 listing that supports filters, pagination, status
filtering, and maps storage/chain records to the V2 DTOs; ensure all methods
include TypeScript interfaces, comprehensive error handling,
permission/ownership checks, and unit tests/mocks to match the task's
testStrategy.

⚠️ Potential issue

Smart contract V2 functionality still pending

Subtask 25.3 for updating smart contracts with V2 functionality is marked as "pending". This is critical for the full V2 implementation to work correctly.

The ServiceRegistry smart contract needs to be updated to support:

• ID-based service management
• Ownership transfers
• Agent assignments
• Hybrid storage pattern with IPFS

This is blocking full V2 functionality. The SDK implementation (ServiceRegistryService.ts) has placeholder error messages indicating the smart contract support is missing.

Would you like me to help implement the smart contract updates or create a detailed specification for the required contract methods?

🤖 Prompt for AI Agents

In .taskmaster/tasks/tasks.json around lines 377-378, Subtask 25.3 is still
marked "pending" because the ServiceRegistry smart contract lacks V2 support
(ID-based service management, ownership transfers, agent assignments, and hybrid
IPFS storage), and the SDK has placeholder errors; update the project by (1)
adding new Solidity functions/events to ServiceRegistry: createService(id,
dataHash), updateService(id, dataHash), transferOwnership(id, newOwner),
assignAgent(id, agent, permissions), revokeAgent(id, agent), and events for
ServiceCreated/Updated/OwnershipTransferred/AgentAssigned; (2) implement hybrid
on-chain/off-chain storage by storing IPFS content hashes on-chain and full
payloads in IPFS, with access control checks in modifiers; (3) write
comprehensive unit tests for these new functions and gas/permission checks; and
(4) remove placeholder errors and implement corresponding methods in
ServiceRegistryService.ts to call the new contract functions and handle
errors/exceptions with proper logging.

⚠️ Potential issue

Service validation disabled but not replaced with V2 validation

Service validation has been commented out but there's no replacement with the new V2 service ID-based validation. This allows proposals to be added for non-existent services, potentially creating inconsistencies.

Apply this diff to properly validate services using V2:

 function addProposal(
     address agent,
     string memory serviceName,
     uint256 servicePrice,
     address tokenAddress
 ) public onlyAgentOwner(agent) {
-    // V2: Service validation removed - services use IDs and are managed independently
-    // require(
-    //     serviceRegistry.isServiceRegistered(serviceName),
-    //     "Service not registered"
-    // );
+    // V2: Service validation using service ID or name lookup
+    // TODO: Replace with service ID-based validation when V2 contract is updated
+    // For now, skip validation as services are managed independently

     _createProposal(agent, serviceName, servicePrice, tokenAddress);
 }

Would you like me to implement proper V2 service validation once the ServiceRegistry contract supports service ID lookups?

Migration function disabled without V2 alternative

The _ensureServiceRegistered function has been disabled but the migration path for V1 services to V2 is unclear. The comment indicates V2 uses IDs and different parameters, but there's no implementation.

Consider implementing a V2-compatible migration strategy:

-// V2: Migration function disabled - services now use different structure
-function _ensureServiceRegistered(string memory serviceName) private {
-    // V2: Disabled - ServiceRegistry V2 uses IDs and different parameters
-    // The new registerService takes (name, serviceUri, agentAddress)
-    // This migration logic would need complete rewrite for V2
+// V2: Migration helper - creates a basic V2 service if not exists
+function _ensureServiceRegisteredV2(string memory serviceName) private {
+    // Check if we need to migrate this service to V2
+    // This would require ServiceRegistry V2 to expose a method to check by name

Replace no-op migration stub with event and off-chain process
_ensureServiceRegistered (AgentsRegistryUpgradeable.sol:365–370) is empty because ServiceRegistry V2 removed on-chain name lookup and stores names off-chain in IPFS metadata (ServiceRegistryUpgradeable.sol:127). On-chain migration by name is unsupported—emit a ServiceMigrationRequired(bytes32 serviceId, address agentAddress) event during upgrade and perform actual registerService(id, serviceUri, agentAddress) calls off-chain by retrieving each service’s metadata from IPFS.

🤖 Prompt for AI Agents

In packages/contracts/contracts/AgentsRegistryUpgradeable.sol around lines
365–370, the _ensureServiceRegistered migration stub is a no-op but must signal
off-chain migration; add a new event declaration
ServiceMigrationRequired(bytes32 indexed serviceId, address indexed
agentAddress) to the contract and modify _ensureServiceRegistered to emit that
event for each agent/service pair that requires migration (do not perform
on-chain name lookups or register calls); document that operators must run an
off-chain migration process which fetches service metadata from IPFS using the
stored serviceId, extracts serviceUri and name, then calls the new
ServiceRegistry.registerService(serviceId, serviceUri, agentAddress) off-chain
via transactions. Ensure the function remains non-reverting and only emits the
event so on-chain upgrade completes safely.

⚠️ Potential issue

Service migration call commented out during agent migration

The service migration is disabled during agent migration from V1, which could leave agents with proposals for services that don't exist in V2.

Consider handling this scenario explicitly:

 // V2: Service migration disabled
-// _ensureServiceRegistered(proposal.serviceName);
+// Skip service migration - services are managed independently in V2
+// Note: This proposal references a V1 service that may not exist in V2
+emit V1ProposalMigrated(agent, proposal.serviceName, i);

Would you like me to create a comprehensive migration strategy that handles V1 proposals with proper V2 service mapping?

In packages/contracts/contracts/AgentsRegistryUpgradeable.sol around lines
385-386, the call to _ensureServiceRegistered was commented out during V2
migration leaving V1 proposals potentially referencing non-existent V2 services;
fix by adding an explicit migration step that iterates V1 proposals and for each
proposal checks whether the referenced service exists in V2, if it does nothing,
if it does not then (a) try to map the old service name to a V2 name via a
migration mapping (add a mapping param or storage field for migration name
pairs), and if a mapping exists update the proposal to the mapped name and call
_ensureServiceRegistered for that mapped name, (b) if no mapping exists either
register a new service entry preserving needed metadata via a migrateService
helper or mark the proposal invalid/expired and emit an event to surface the
action; include proper access control for migration, add events for
mapping/registration/rejection, and add unit tests covering mapped, newly
registered, and rejected proposals.

🛠️ Refactor suggestion

Legacy getService method retained but may cause confusion

The getService(name: string) method is retained alongside the new getServiceById(serviceId: string). Since V2 services use IDs rather than names, this could cause confusion.

Consider deprecating the name-based lookup or clarifying its limited use:

 /**
  * Gets a service by name.
+ * @deprecated Use getServiceById() instead. V2 services primarily use IDs.
  * @param {string} name - The name of the service.
  * @returns {Promise<ServiceRecord>} A promise that resolves to the service.
+ * @throws {Error} Service names are stored off-chain in V2 and may not support direct lookup.

Verified that packages/contracts/ignition/modules contains no imports or m.getParameter calls for TaskRegistryUpgradeableModule, initialTaskId, taskRegistryProxy, or newTaskRegistryImpl.

packages/contracts/ignition/params/local.json (1)

Same as baseSepolia: ensure no remaining local references to TaskRegistry params.

Use the same script from the previous comment at the repo root.

packages/contracts/ignition/modules/UpgradeRegistries.ts (2)

50-55: No downstream references to removed TaskRegistry exports found. Ripgrep searches for newTaskRegistryImpl and taskRegistryProxy across the codebase returned no matches—safe to update the return shape as-is.

41-47: Be explicit about upgrade caller, initialization data, and run storage layout validation

• Add a from option to each m.call so the upgrade is sent from the account authorized by your _authorizeUpgrade override (e.g. from: m.getAccount(0)).
• If the new implementation has an initializer or migration step, encode and pass its initializer payload instead of the empty "0x" bytes.
• Before executing upgrades, verify both the old and new implementations support upgradeToAndCall and compare their storage layouts (e.g. using OpenZeppelin’s layout validation against your actual deployment artifacts).

147-177: Fix potential division by zero in initial rating calculation

When totalRatings is 0 (first rating), line 169-173 performs (reputation * (totalRatings - 1) + _rating) / totalRatings which becomes (0 * -1 + _rating) / 1. This works due to Solidity 0.8+ underflow protection converting -1 to a large number, but it's misleading and could cause issues.

Apply this fix for clearer logic:

 function addRating(
     address agent,
     uint256 _rating
 ) public returns (uint256) {
     require(
         agents[agent].agent != address(0),

         "Rating must be between 0 and 100"
     );
     
     // Mark that this user has rated this agent

Functions missing complete NatSpec:

• hasUserRated (lines 194-196): Missing all NatSpec tags
• removeAgent (lines 237-256): Missing @param tag
• setServiceRegistry (lines 96-99): Missing complete documentation

Please add complete NatSpec documentation following this pattern:

/**
 * @notice Brief description of function purpose
 * @dev Technical details about implementation
 * @param paramName Description of parameter
 * @return Description of return value
 */

223-234: Add registration check before ownership check for better error messages

The function should verify agent registration before checking ownership to provide clearer error messages. Currently, non-existent agents trigger "Not the owner of the agent" which is misleading.

Apply this fix:

 function setAgentData(
     address agent,
     string memory name,
     string memory agentUri
-) external onlyAgentOwner(agent) {
-    require(agents[agent].agent != address(0), "Agent not registered");
+) external {
+    require(agents[agent].agent != address(0), "Agent not registered");
+    require(agents[agent].owner == msg.sender, "Not the owner of the agent");
     
     agents[agent].name = name;
     agents[agent].agentUri = agentUri;
     
     emit AgentDataUpdated(agent, name, agentUri);
 }

---

247-256: Apply consistent validation pattern for removeAgent

Similar to setAgentData, the registration check should come before the ownership check.

Apply this fix:

-function removeAgent(address agent) external onlyAgentOwner(agent) {
-    require(agents[agent].agent != address(0), "Agent not registered");
+function removeAgent(address agent) external {
+    require(agents[agent].agent != address(0), "Agent not registered");
+    require(agents[agent].owner == msg.sender, "Not the owner of the agent");
     
     address agentOwner = agents[agent].owner;
     
     // Clear agent data
     delete agents[agent];
     
     emit AgentRemoved(agent, agentOwner);
 }

30-36: Mock V1 registry type mismatch will cause migration tests to fail

The test deploys a ServiceRegistryUpgradeable as the mock V1 registry, but AgentsRegistryUpgradeable expects an IAgentRegistryV1 implementation. Any migrateAgent calls will fail.

Create a proper mock contract:

// packages/contracts/contracts/mocks/MockAgentRegistryV1.sol
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.22;

import "../interfaces/IAgentRegistryV1.sol";

contract MockAgentRegistryV1 is IAgentRegistryV1 {
    mapping(address => AgentData) public agentData;
    
    function setAgentData(address agent, AgentData calldata data) external {
        agentData[agent] = data;
    }
    
    function getAgentData(address agent) external view returns (AgentData memory) {
        return agentData[agent];
    }
}

Then update the test:

-        // Deploy mock V1 registry for migration compatibility
-        mockV1Registry = await upgrades.deployProxy(ServiceRegistry, [], {
-            initializer: "initialize",
-            kind: "uups"
-        });
+        // Deploy mock V1 registry for migration compatibility
+        const MockAgentRegistryV1 = await ethers.getContractFactory("MockAgentRegistryV1");
+        mockV1Registry = await MockAgentRegistryV1.deploy();
         await mockV1Registry.waitForDeployment();

---

167-175: Test expects wrong error message for non-existent agent

The test expects "Not the owner of the agent" when updating a non-existent agent, but this is misleading. After fixing the contract to check registration first, update this test.

         it("Should fail to update non-existent agent", async function () {
             await expect(
                 agentsRegistry.connect(addr1).setAgentData(
                     agentAddr2.address,
                     "New Name",
                     "New URI"
                 )
-            ).to.be.revertedWith("Not the owner of the agent");
+            ).to.be.revertedWith("Agent not registered");
         });

---

333-339: Test missing event assertion for setServiceRegistry

The test should verify that the ServiceRegistryUpdated event is emitted when updating the registry.

-            await agentsRegistry.connect(owner).setServiceRegistry(
-                await newServiceRegistry.getAddress()
-            );
+            const tx = await agentsRegistry.connect(owner).setServiceRegistry(
+                await newServiceRegistry.getAddress()
+            );
+
+            await expect(tx)
+                .to.emit(agentsRegistry, "ServiceRegistryUpdated")
+                .withArgs(
+                    await serviceRegistry.getAddress(),
+                    await newServiceRegistry.getAddress()
+                );

🧹 Nitpick comments (3)

packages/contracts/contracts/AgentsRegistryUpgradeable.sol (2)

45-51: Consider adding onlyRegisteredAgent modifier for consistency

Multiple functions check agents[agent].agent != address(0). Consider extracting this into a reusable modifier for consistency and gas optimization.

+modifier onlyRegisteredAgent(address agent) {
+    require(agents[agent].agent != address(0), "Agent not registered");
+    _;
+}
+
 modifier onlyAgentOwner(address agent) {
     require(
         agents[agent].owner == msg.sender,
         "Not the owner of the agent"
     );
     _;
 }

Then use it in addRating, setAgentData, and removeAgent.

⚠️ Potential issue

Clear rating history when removing agent

When an agent is removed, the rating history in the hasRated mapping is not cleared. This could prevent users from rating a re-registered agent.

Consider either:

1. Document that rating history persists across re-registrations (intended behavior)
2. Add a mechanism to clear rating history on removal

If you want to clear history, additional state tracking would be needed since you can't iterate over all raters. Consider adding an agent version/nonce that increments on each registration.

🛠️ Refactor suggestion

Add test coverage for agent migration functionality

The test suite is missing coverage for the migrateAgent function, which is a critical V1 to V2 migration path.

    beforeEach(async function () {
        // Deploy proper mock V1 registry

        mockV1Registry = await MockAgentRegistryV1.deploy();
        
        // Re-deploy AgentsRegistry with mock V1
        agentsRegistry = await upgrades.deployProxy(

913-929: Align status transition rules with delete policy and include serviceId in errors.

• Disallow published → deleted via transition helper (keep delete via dedicated deleteService flow if desired).
• Include serviceId in ServiceStatusError.
• Update caller to pass serviceId.

-  private validateStatusTransition(currentStatus: ServiceStatus, newStatus: ServiceStatus): void {
+  private validateStatusTransition(serviceId: string, currentStatus: ServiceStatus, newStatus: ServiceStatus): void {
     const validTransitions: Record<ServiceStatus, ServiceStatus[]> = {
       'draft': ['published', 'deleted'],
-      'published': ['archived', 'deleted'],
+      'published': ['archived'],
       'archived': ['published', 'deleted'],
       'deleted': []
     };
     const allowedTransitions = validTransitions[currentStatus] || [];
     if (!allowedTransitions.includes(newStatus)) {
-      throw new ServiceStatusError(
-        "unknown", 
-        currentStatus, 
-        `Cannot transition from ${currentStatus} to ${newStatus}. Allowed: ${allowedTransitions.join(', ')}`
-      );
+      throw new ServiceStatusError(serviceId, currentStatus, allowedTransitions.join(' or ') || 'n/a');
     }
   }

-      this.validateStatusTransition(service.status, status);
+      this.validateStatusTransition(serviceId, service.status, status);

Additionally, deleteService already blocks deletion from 'published'; keep that check.

315-332: Fail fast with a clear NotImplemented for read-dependent flows until getServiceById exists.

• Replace the generic throw in getServiceById with a clear NotImplemented message.
• Consider guarding update/delete/transfer/status/assign/unassign/getServiceOwner/getAssignedAgents/getServicesByAgent to throw the same until read APIs are wired.

-      // In a real implementation, this would query by service ID
-      // For now, we'll need to implement a mapping system
-      throw new Error("getServiceById not yet implemented - requires smart contract V2");

🛠️ Refactor suggestion

Adopt custom errors and replace revert strings.

Project guidelines require custom errors for gas savings and clarity.

Example (apply throughout):

+error NotServiceOwner();
+error ServiceDoesNotExist();
+error ServiceUriRequired();
+error InvalidAgent();
+error InvalidStatusTransition();
+error CannotUpdateDeleted();
+error NoAgentAssigned();
+error CannotDeletePublished();

-    modifier onlyServiceOwner(uint256 serviceId) {
-        require(services[serviceId].owner == msg.sender, "Not service owner");
+    modifier onlyServiceOwner(uint256 serviceId) {
+        if (services[serviceId].owner != msg.sender) revert NotServiceOwner();
         _;
     }
-    modifier serviceExists(uint256 serviceId) {
-        require(serviceId > 0 && serviceId <= nextServiceId, "Service does not exist");
+    modifier serviceExists(uint256 serviceId) {
+        if (!(serviceId > 0 && serviceId <= nextServiceId)) revert ServiceDoesNotExist();
         _;
     }

-        require(bytes(serviceUri).length > 0, "Service URI required");
+        if (bytes(serviceUri).length == 0) revert ServiceUriRequired();

⚠️ Potential issue

Connect the contract to the signer for all write calls.

registerService, updateService, and unassignAgentFromService send transactions but don’t .connect(this.signer). This will fail when the instance was constructed with a provider-only contract.

Apply:

(and also apply same fix at 262-263), you compute a new serviceUri when updating
metadata but never assign it back to the updatedService returned to callers; set
updatedService.serviceUri = serviceUri after computing it in both the IPFS and
fallback branches (and ensure the later return path at lines 262-263 uses that
updatedService with the new serviceUri) so callers receive the fresh URI.

TypeScript fails because response.json() is typed as unknown and there's an
unnecessary guard that throws if this.ipfsSDK is not set; remove the IPFS SDK
presence check and its throw (allow read-only IPFS fetches), and explicitly type
the parsed JSON as IPFSMetadata (e.g., assign await response.json() to a
variable cast to IPFSMetadata or use a generic) so the function returns the
correct IPFSMetadata type.

Avoid double IPFS uploads in createServiceWithMetadata.

You upload metadata, then call registerService which uploads again. This doubles cost/latency.

Option A (preferred): change registerService to accept a prebuilt serviceUri.
Option B: skip the explicit upload here and rely on registerService to upload metadata.

-      // Upload metadata to IPFS
-      const ipfsUri = await this.uploadMetadata(metadata);
-
-      // Create service with the original method, which will handle IPFS upload internally
-      return await this.registerService(serviceData);
+      // Delegate upload to registerService to avoid double uploads
+      return this.registerService(serviceData);

the method uploads metadata to IPFS but ignores the returned ipfsUri, causing
updateService to re-upload; capture the return value from uploadMetadata (e.g.
const { ipfsUri } = await this.uploadMetadata(...)) and include that ipfsUri in
the updateParams.metadata object (add the ipfsUri field or the expected key
updateService reads) so updateService receives the already-uploaded URI and does
not perform a second upload; ensure uploadMetadata's return type is used and
propagated to updateService.
