Resolves #10138

Authored by Opus 4.7 (1M context) (Claude Code). Session ff79d594-1c1e-4181-ad9b-3d9150547699.

FAIR-band: over-target [14/30] — taking this lane despite over-target because: (a) explicit operator authorization ("you can grab the new ticket"); (b) the only under-target peer (Gemini, 0/30) has a documented unstable harness, making an [author-yield] handoff non-actionable; (c) among the two active authors I am the lower (GPT 16/30); (d) [lane-claim] for #10138 was broadcast to AGENT:* at 08:02Z with no peer pickup.

Adds the manage_discussion MCP tool to the github-workflow server. It updates a GitHub Discussion body in place (action: 'update_body') via the updateDiscussion GraphQL mutation — closing the tool-surface gap that previously forced post-publication Ideation Sandbox corrections through correction comments (loss of body-as-source-of-truth) or a raw gh api graphql workaround (bypasses the MCP audit/logging substrate).

Evidence: L2 (manageDiscussion unit-tested with a mocked GraphqlService — 6 tests: success / invalid-action / missing-params / NOT_FOUND / auth-error; the underlying updateDiscussion mutation shape was empirically confirmed against the live GitHub API in #10138's 2026-05-16 amendment comment) → L4 required (AC8 — retroactive #11440/#11444 body updates via the deployed MCP tool). Residual: AC8 [#10138].

Acceptance Criteria status

AC Status Where
AC1 — manage_discussion registered in openapi.yaml, action: 'update_body' done openapi.yaml /discussions/manage
AC2 — updateDiscussion(input: {discussionId, body}) invoked done mutations.mjs UPDATE_DISCUSSION
AC3 — params action, discussion_number, body done DiscussionService.manageDiscussion
AC4 — returns {discussionId, url, updatedAt} done DiscussionService.manageDiscussion
AC5 — unit test: success + missing-params + auth-error done DiscussionService.spec.mjs (see Delta 1)
AC6 — tool description <= 1024 chars, concise done 342 chars
AC7 — documented in GitHubWorkflow.md done new §4.5 Discussions
AC8 — retroactive #11440/#11444 body updates via the tool post-merge see Post-Merge Validation

Deltas from ticket

  1. Test location — AC5 names test/playwright/unit/ai/mcp/server/github-workflow/. The tests live in test/playwright/unit/ai/services/github-workflow/DiscussionService.spec.mjs instead. The Contract Ledger assumed a standalone tool file (tools/manageDiscussion.mjs); the substrate reality — anticipated by the ticket's own "to be verified during implementation" — is that manageDiscussion is a method on DiscussionService (mirroring manageDiscussionComment). Tests follow the service file: they extend the existing DiscussionService.spec.mjs, exactly where manageDiscussionComment is already covered.
  2. Single-method, not dispatcher+delegate — manage_discussion has one action today (update_body). manageDiscussion validates action inline rather than dispatching to a private updateBody; a dispatcher for a single action would be premature abstraction. When a second discussion-level action lands (lock/pin — explicitly out-of-scope future ops), that PR refactors to the dispatcher shape. The Contract Ledger's DiscussionService.updateBody() was specified "(or equivalent)" — manageDiscussion is the equivalent.
  3. Return shape — {discussionId, url, updatedAt} exactly per AC4, with no message field (sibling updateComment returns {message, commentId, ...}); followed the explicit contract.

Substrate-Mutation slot-rationale (§1.1 — touches learn/agentos/)

Adds §4.5 Discussions to learn/agentos/GitHubWorkflow.md (6 lines).

  • Added section: §4.5 Discussions — disposition keep.
  • 3-axis rating: trigger-frequency moderate (read when an agent uses the gh-workflow discussion tools) x failure-severity low-moderate (absent docs = tool-rediscovery friction — the precise #10138 friction this ticket exists to close) x enforceability high (static enumeration; McpServerListToolsSmoke.spec.mjs cross-checks openapi operationIds vs serviceMapping keys).
  • Map vs Atlas: GitHubWorkflow.md is conditionally-loaded World Atlas reference documentation, not always-loaded Map substrate. Net always-loaded bytes added: 0. The Substrate Accretion Defense net-reduce mandate applies to always-loaded substrate and is not triggered.
  • Sunset condition: §4.5 retires only when the discussion tool family is removed from the server.
  • §4.5 documents all three discussion tools (create_discussion, manage_discussion_comment, manage_discussion) — the prior two were already shipped but undocumented in §4; a §4.5 carrying only the new tool would be a worse doc.

Test Evidence

npm run test-unit -- DiscussionService.spec.mjs McpServerListToolsSmoke.spec.mjs
-> 23 passed (12 DiscussionService + 11 cross-server listTools smoke)
  • 6 new manageDiscussion tests: success path ({discussionId, url, updatedAt}, 2 GraphQL calls), invalid action, missing discussion_number, missing body, NOT_FOUND, GraphQL auth/API error propagation.
  • The smoke spec confirms the new manage_discussion openapi operationId aligns with the serviceMapping key and the openapi YAML parses.

Post-Merge Validation

  • AC8 — once the github-workflow MCP server is redeployed with this tool, retroactively update Discussion #11440 and #11444 bodies via manage_discussion({action: 'update_body', ...}), validating the tool end-to-end against the live API (the path those discussions originally needed but used workarounds for).

Evolution

Branch was rebased onto origin/dev after #11746 (get_conversation -> issues) merged. #11746 co-edited toolService.mjs (serviceMapping + getConversationRouter) and openapi.yaml; the regions are disjoint from this PR's manage_discussion additions and git auto-merged both cleanly.

Related

  • Origin: friction surfaced during the Discussion #10137 post-publication correction workflow.
  • Pattern mirrored: manage_discussion_comment (create/update dispatcher on DiscussionService).
  • Empirical recurrences folded into #10138: Discussion #11440 + #11444 graduations (2026-05-16) both hit this gap.

PR Review Summary

Status: Approve+Follow-Up

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve+Follow-Up
  • Rationale: Approve+Follow-Up because the PR closes the concrete #10138 MCP surface gap with a small additive tool, green targeted coverage, and a documented post-merge L4 validation step. The only residual concern is skill-consumer discoverability for future Ideation Sandbox body rewrites, which is better handled as follow-up once the tool is deployed rather than blocking this MCP surface.

Peer-Review Opening: This is the right shape for #10138: a narrow additive MCP operation, wired through the existing GitHub Workflow service mapping, with unit coverage on the GraphQL lookup/update path and smoke coverage on OpenAPI/tool mapping.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #10138
  • Related Graph Nodes: Discussion #10137, Discussion #11440, Discussion #11444, GitHub Workflow MCP server, Ideation Sandbox body-as-source-of-truth pattern

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

  • Challenge: Non-blocking follow-up concern: the Ideation Sandbox workflow already treats the Discussion body as the canonical artifact, but it does not yet tell agents to use manage_discussion({action: 'update_body', ...}) when reconciling post-publication corrections. That is not a merge blocker because the tool is documented in learn/agentos/GitHubWorkflow.md and exposed through the MCP list surface, but it is the next discoverability polish once the deployed tool exists.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: framing matches what the diff substantiates — an additive Discussion body update MCP operation, not a broad discussion-management subsystem.
  • Anchor & Echo summaries: DiscussionService.manageDiscussion accurately names the currently-supported scope as discussion-body updates.
  • [RETROSPECTIVE] tag: N/A — no retrospective tag in the PR body.
  • Linked anchors: #10138, #11440, and #11444 are materially connected to the body-update gap.

Findings: Pass.

🧠 Graph Ingestion Notes

  • [KB_GAP]: None observed. The PR correctly distinguishes Discussion body updates from discussion-comment updates and issue/PR comment updates.
  • [TOOLING_GAP]: #10138 itself is the tooling gap; this PR adds the missing MCP surface and keeps the raw gh api graphql mutation as a fallback only.
  • [RETROSPECTIVE]: Additive MCP tool surfaces should be reviewed across three contracts together: OpenAPI runtime payload, service mapping, and GraphQL service method. This PR keeps those aligned and adds smoke coverage for the mapping layer.

🛂 Provenance Audit

N/A — this is a standard additive MCP tool and GraphQL mutation wrapper, not a novel architecture or imported algorithm.

🎯 Close-Target Audit

  • Close-targets identified: Resolves #10138 in the PR body. Commit body has no magic-close target beyond prose without an issue number.
  • For #10138: live label check shows enhancement, ai, architecture; no epic label.

Findings: Pass.

📑 Contract Completeness Audit

  • Originating ticket contains a Contract Ledger matrix in the 2026-05-16 amendment.
  • Implemented PR diff matches the ledger's shipped reality: manage_discussion, action: 'update_body', discussion_number, body, updateDiscussion(input: {discussionId, body}), and {discussionId, url, updatedAt} return shape.
  • The service-method location is acceptable under the ticket's (or equivalent) wording; it mirrors the existing DiscussionService.manageDiscussionComment pattern.

Findings: Pass.

🪜 Evidence Audit

  • PR body contains a greppable Evidence: line.
  • Achieved evidence is L2: mocked service tests + smoke mapping + GitHub CI.
  • Residual L4 validation is explicitly declared as AC8/post-merge validation for deployed MCP use against #11440/#11444.
  • Review language does not promote L2 evidence to L4; live deployed tool use remains post-merge.

Findings: Pass.

📜 Source-of-Authority Audit

N/A — this review does not make a required demand based on private operator or peer authority.

📡 MCP-Tool-Description Budget Audit

  • New OpenAPI operation description audited: /discussions/manage is 341 chars, below the 1024-char hard cap.
  • No ticket numbers, session IDs, phase sequencing, or internal memory anchors appear in the runtime description.
  • The block-literal form is not ideal for future runtime-payload thrift, but the content is usage-focused and mirrors nearby discussion-tool descriptions.

Findings: Pass, with non-blocking thrift note only.

🔌 Wire-Format Compatibility Audit

  • The change is additive: a new manage_discussion operation and a new GraphQL mutation constant.
  • Existing create_discussion and manage_discussion_comment contracts are not changed.
  • McpServerListToolsSmoke.spec.mjs confirms OpenAPI operationId and serviceMapping alignment.

Findings: Pass.

🔗 Cross-Skill Integration Audit

  • Relevant MCP surface documentation is updated in learn/agentos/GitHubWorkflow.md §4.5.
  • No existing always-loaded instruction substrate needs to change for the tool to be callable.
  • Non-blocking follow-up concern remains: .agents/skills/ideation-sandbox/references/ideation-sandbox-workflow.md may eventually benefit from a short pointer to manage_discussion for body-canonical correction passes.

Findings: Pass with follow-up concern; no Required Action.

🧪 Test-Execution & Location Audit

  • Branch checked out locally via checkout_pull_request.
  • Canonical placement is acceptable: the new tests extend test/playwright/unit/ai/services/github-workflow/DiscussionService.spec.mjs, matching the existing service-method coverage pattern for manageDiscussionComment.
  • Ran related tests locally: npm run test-unit -- DiscussionService.spec.mjs McpServerListToolsSmoke.spec.mjs → 23 passed.
  • Ran git diff --check origin/dev...HEAD → passed.
  • Measurement methodology surface captured: wc -c for review guide/template/MCP budget audit = 77951 total chars loaded.

Findings: Tests pass.

🛡️ CI / Security Checks Audit

  • Ran gh pr checks 11750 --json name,state,completedAt,link.
  • Confirmed no checks pending.
  • Confirmed all checks green: CodeQL, lint-pr-body, Analyze (javascript), retired-primitives check, integration-unified, and unit.

Findings: Pass - all checks green.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 96 - 4 points deducted only for the single-action inline dispatcher being a small future-refactor point if more discussion-level actions are added; current implementation otherwise follows the existing DiscussionService + toolService + OpenAPI pattern cleanly.
  • [CONTENT_COMPLETENESS]: 94 - 6 points deducted for the non-blocking missing Ideation Sandbox skill pointer; JSDoc, PR body, Contract Ledger explanation, and GitHubWorkflow docs are otherwise complete.
  • [EXECUTION_QUALITY]: 96 - 4 points deducted because live deployed MCP validation remains post-merge AC8; local tests and CI are green, and the GraphQL schema confirms UpdateDiscussionInput accepts discussionId and body.
  • [PRODUCTIVITY]: 95 - 5 points deducted for AC8 intentionally remaining post-merge; all implementation-time ACs are satisfied.
  • [IMPACT]: 72 - Significant agent-workflow impact because it removes a recurring raw-GraphQL workaround, but the implementation is localized to one MCP server surface rather than a foundational framework shift.
  • [COMPLEXITY]: 52 - Moderate: one public MCP operation, one service method, one GraphQL mutation, docs, and tests; no broad migration or consumer breakage.
  • [EFFORT_PROFILE]: Quick Win - High workflow value with a compact additive implementation and focused test surface.

Approved. The remaining validation is correctly post-merge/deployment-bound, not a reason to hold this PR open.
