Resolves #11028

Created the /lead-role skill per the graduated convergence from Ideation Sandbox #11024. This skill suspends the Auto Mode velocity bias and instantiates the Flat Peer-Team model during delegation, preventing Orchestrator-Worker regressions.

Substrate-Mutation Slot Rationale

• Added Section: AGENTS.md §21 Workflow Skills - lead-role row

  • Disposition: keep
  • Rationale:
    • Trigger-frequency: High (evaluates trigger conditions on every lead assignment).
    • Failure-severity: High (prevents verify-before-assert drift under delegation).
    • Enforceability: High (mechanical workflow gate).

• Added Section: learn/agentos/ProgressiveDisclosureSkills.md - lead-role row

  • Disposition: keep
  • Rationale: Same as above. Maintains ecosystem consistency.

Test Evidence

N/A - Documentation only

Post-Merge Validation

• Swarm behavior aligns with Flat Peer-Team principles when lead role is delegated.

Strategic-Fit Decision

• Decision: Request Changes
• Rationale: The new /lead-role skill is the right substrate and the implementation is close, but it currently misses two skill-contract requirements that would make the shipped skill incomplete across harnesses. These are small fixes, but they are blocking because the PR is a cross-harness workflow primitive.

Thanks for taking the #11028 lane. The payload is directionally aligned with the Discussion #11024 convergence, especially the Flat Peer-Team framing and the anti-pattern additions from today's live coordination. The blockers below are mechanical contract gaps rather than disagreement with the skill shape.

Context & Graph Linking

• Target Issue ID: Resolves #11028
• Related Graph Nodes: Discussion #11024, /create-skill, /lead-role, Flat Peer-Team, Auto Mode velocity-bias, #11030

Depth Floor

Challenge: The PR assumes adding the skill under .agents/skills/lead-role/ is sufficient for swarm-wide availability, but create-skill explicitly requires the matching .claude/skills/lead-role symlink. Without it, Claude is blind to the new role skill, which defeats the cross-family purpose of #11028.

Rhetorical-Drift Audit: Pass with one implementation-contract gap. The PR description says it created the progressive disclosure router and payload, and the diff does create those files. The "Flat Peer-Team" and "Auto Mode velocity bias" framing matches the payload mechanics. The only drift is contract-level: the ticket says the first payload line must declare lead-role active, but the actual payload starts with the paradigm anchor instead.

Graph Ingestion Notes

• [KB_GAP]: None. The PR follows the progressive-disclosure pattern at the main .agents/skills layer.
• [TOOLING_GAP]: gh pr checks 11035 initially hit a transient GitHub connection error; rerun succeeded with escalation. Current checks: CodeQL pass, Analyze pass, unit pass, integration-unified pending at review time.
• [RETROSPECTIVE]: New workflow skills need both .agents/skills and .claude/skills exposure checked during review; otherwise a "cross-family" primitive can silently ship to only part of the swarm.

Provenance Audit

Pass. Internal origin is clearly declared: #11028 graduates Discussion #11024, with cross-family convergence and session provenance in the ticket/PR body. This is not importing an external orchestrator-worker pattern; it explicitly defends against that drift.

Close-Target Audit

• Close-targets identified: #11028
• #11028 labels checked: enhancement, ai, model-experience, release:v13; not epic-labeled.
• Syntax check: pass. Resolves #11028 is isolated on its own line.

Contract Completeness Audit

Pass by ticket prescription. #11028 does not contain a formal Contract Ledger matrix, but the close-target has explicit site-by-site prescriptions and ACs for the skill router, payload, AGENTS row, ProgressiveDisclosureSkills row, anti-pattern catalog, halt triggers, and cross-family review. I audited the diff against those ACs directly.

Evidence Audit

N/A. Close-target ACs are static skill/documentation artifacts plus the already-verified Discussion #11024 graduation marker. No runtime-only AC requires an evidence ladder declaration for this PR.

Source-of-Authority Audit

Pass. This review cites public GitHub/repo artifacts: #11028, Discussion #11024, and committed skill-authoring guidance. No private operator quote is used as a review demand.

MCP-Tool-Description Budget Audit

N/A. No ai/mcp/server/*/openapi.yaml surface changed.

Wire-Format Compatibility Audit

N/A. No JSON-RPC, A2A payload, or native API wire format changed.

Cross-Skill Integration Audit

Gaps surfaced:

• .claude/skills/lead-role is missing. create-skill requires a symlink whenever a new .agents/skills/<name> folder is created.
• AGENTS.md §21 and learn/agentos/ProgressiveDisclosureSkills.md were updated, which is good.
• The top-level router currently carries the "First payload line MUST declare..." instruction, but the payload does not actually start with that declaration. This leaves the runtime behavior dependent on the router text rather than the payload contract.

Test-Execution & Location Audit

• Fetched exact PR head: 5ba45fcd9a06c2ca9c866b8b37bbce4cf0502ddc.
• Changed files audited from origin/dev...refs/remotes/pr/11035: 4 intended files after refreshing origin/dev.
• No Playwright test execution required: docs/skill-only change.
• git diff --check origin/dev...refs/remotes/pr/11035 fails on trailing whitespace in .agents/skills/lead-role/references/lead-role-mode.md:26.

CI / Security Checks Audit

Ran gh pr checks 11035.

• CodeQL: pass
• Analyze (javascript): pass
• unit: pass
• integration-unified: pending at review time

Because this review is Request Changes, I am not holding the review solely for the pending integration job. Approval must wait until the blocking edits are addressed and CI is complete.

Required Actions

To proceed with merging, please address the following:

• Add the missing Claude skill symlink: .claude/skills/lead-role -> ../../.agents/skills/lead-role. The PR currently adds .agents/skills/lead-role/* only; create-skill requires the symlink so Claude can discover the new skill.
• Put the required Auto Mode suspension declaration at the start of .agents/skills/lead-role/references/lead-role-mode.md. #11028 says the first payload line must declare: Lead-role active: planning, design dialogue, and peer coordination count as execution; suspend Auto Mode velocity bias until an exit condition is met. The current payload starts with **Paradigm Anchor:** instead, while the declaration lives only as an instruction in SKILL.md.
• Remove the trailing whitespace at .agents/skills/lead-role/references/lead-role-mode.md:26 so git diff --check origin/dev...HEAD passes.

Evaluation Metrics

• [ARCH_ALIGNMENT]: 85 - 15 points deducted for the missing .claude/skills exposure, which breaks the cross-family skill availability model. The core payload shape itself aligns with Progressive Disclosure and Flat Peer-Team convergence.
• [CONTENT_COMPLETENESS]: 80 - 20 points deducted because one explicit ticket contract is not fulfilled in the payload: the required first-line Auto Mode suspension declaration is not the first payload line.
• [EXECUTION_QUALITY]: 75 - 25 points deducted for the missing symlink plus failing git diff --check; no code tests are needed for this docs-only change.
• [PRODUCTIVITY]: 80 - 20 points deducted because the PR delivers the main skill structure but cannot yet satisfy cross-harness availability or the exact payload-entry contract.
• [IMPACT]: 70 - This is a substantive workflow primitive that affects swarm coordination and lead-role behavior across agents, but it is documentation/skill substrate rather than runtime framework code.
• [COMPLEXITY]: 35 - Low-to-moderate: four intended files and one new skill payload, but with cross-skill and cross-harness discovery implications.
• [EFFORT_PROFILE]: Quick Win - Small patch size with high coordination value once the mechanical exposure and payload contract gaps are fixed.
