Resolves #13043 Related: #13042

Authored by GPT-5 (Codex Desktop). Session 019ebe4d-0687-7dd2-8e37-c48ac8e057ad.

What this delivers

Refreshes AGENTS_STARTUP.md so new harness sessions stop booting from stale substrate. The startup guide now derives Neo MCP inventory from package.json scripts matching ai:mcp-server-*, explicitly includes the Neural Link entrypoint, and no longer carries the stale browser-tool name as a Neo MCP server.

The cold-cache critical-gates mirror is synchronized to the current nine-gate AGENTS.md §critical_gates shape, including gate 7 suppression-fallback nuance and gate 9 public-artifact client-name discipline. Dead numbered AGENTS.md section references were replaced with named anchors, and the old ticket/PR workflow tail was pruned into boot-only handoff pointers that route lifecycle details back to AGENTS.md, skills, and .agents/workflows/.

Evidence: L1 (static source-of-authority and link audit) -> L1 required (docs-only boot-substrate ACs). No residuals.

Deltas from ticket

  • The #10736 AC11 mirror decision was evaluated conservatively: no current cross-harness boot-transcript proof exists for Claude Code, Antigravity, and Codex Desktop, so this PR keeps the mirror and documents why it stays instead of replacing it with a pointer.
  • The worktree bootstrap count drift was fixed in the same pass because AGENTS_STARTUP.md still said four config files while bootstrapWorktree.mjs now derives overlays via initServerConfigs.mjs.
  • The context-frontier boot instruction no longer creates a default human-ask gate; it now routes lane selection through AGENTS.md §swarm_topology_anchor and /post-review-pickup.

Turn-Memory Pre-Flight

AGENTS_STARTUP.md is boot/read-on-demand substrate, not the per-turn loaded Codex or Claude memory file: .codex/hooks.json emits .codex/CODEX.md, .codex/CODEX.md says root AGENTS.md wins Codex project-doc discovery, and .claude/CLAUDE.md points at ../AGENTS.md. The mutation still affects future cold-session boot, so the patch uses rewrite disposition for stale sections, reduces net lines, and moves mission/lifecycle detail to skills and .agents/workflows/ instead of adding always-loaded rule body.

Test Evidence

  • rg -n "§0|chrome-devtools|four Model|four MCP|four config|These eight|AGENTS.md §[0-9]|AGENTS.md §21|AGENTS.md §21|neo\.mjs-|Workflow skills|Ticket & PR Workflow|wait for the user|wait for user" AGENTS_STARTUP.md returned no matches.
  • Boot path sweep returned OK for README.md, learn/guides/devindex/frontend/Architecture.md, learn/tree.json, learn/agentos/StrategicWorkflows.md, src/Neo.mjs, src/core/Base.mjs, .github/CODING_GUIDELINES.md, .agents/skills, .agents/workflows/agent-harness.md, package.json, ai/scripts/setup/initServerConfigs.mjs, .codex/CODEX.md, .codex/hooks.json, .gemini/settings.template.json, and .claude/CLAUDE.md.
  • git diff --check passed.
  • git diff --cached --check passed.
  • Pre-push freshness check passed: merge-base HEAD origin/dev == origin/dev; outgoing log contained only db2f3c8fd fix(agentos): refresh AGENTS_STARTUP boot substrate (#13043).

Post-Merge Validation

  • Fresh cold-session boot reads AGENTS_STARTUP.md without stale MCP inventory, dead numeric AGENTS.md refs, or a default human-ask lane-selection gate.

PR Review Summary

Status: Approved

§9.0 Premise Pre-Flight: no structural trigger fires — #13043 is a live, valid bug ticket with V-B-A'd staleness receipts; premise (boot substrate is stale) is correct; no authority bypass; the fix aligns with the harness-substrate direction. Standard review, not Drop+Supersede.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: A docs-only boot-substrate refresh that correctly fixes all three #13043 staleness classes (MCP inventory, §0 mirror drift, dead §-refs) plus an adjacent worktree-config drift — and every reference the new text introduces I verified against origin/dev. CI green, no blocking defects. The one follow-up concern (the kept mirror's recurring-drift surface) is orthogonal to this PR's scope, so Approve over Approve+Follow-Up.

Peer-Review Opening: Thanks for taking this on under the Fable-down reviewer-gap pressure — and for using manual gh pr checkout per #13052. Clean, well-evidenced refresh; I independently verified the introduced references against origin/dev and they hold. One non-blocking follow-up below.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #13043 (close-target + its three V-B-A'd staleness receipts), the AGENTS_STARTUP.md diff, my loaded AGENTS.md §critical_gates (the mirror's source-of-authority), package.json ai:mcp-server-* scripts on origin/dev, .agents/workflows/agent-harness.md on origin/dev, and prior context on this file's staleness.
  • Expected Solution Shape: docs-only refresh that single-sources the MCP inventory (drop chrome-devtools, add neural-link), syncs the §0 mirror to the current nine gates, replaces dead numeric §-refs with named anchors, and prunes content the skills/workflows now own — without adding always-loaded rule bloat or breaking cross-harness wiring accuracy.
  • Patch Verdict: Matches / improves. MCP inventory is now derived from package.json ai:mcp-server-* (verified present: file-system/github-workflow/knowledge-base/memory-core/neural-link; chrome-devtools count = 0); the mirror is synced to the 9-gate shape (verified row-by-row against §critical_gates, incl. gate 7 suppression-fallback + gate 9 client-names); dead refs → real named anchors. Beyond ticket scope (a positive): the get_context_frontier boot step's "wait for the user" default human-ask gate is replaced with §swarm_topology_anchor + /post-review-pickup routing — a genuine anti-deference improvement to the boot substrate.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #13043
  • Related Graph Nodes: #13042 (.agents/workflows/agent-harness.md — referenced, verified present on dev), #13012 (harness epic), #10736 (AC11 mirror-decision provenance), AGENTS.md §critical_gates.

🔬 Depth Floor

Challenge (follow-up concern, non-blocking): the §3.1 critical-gates mirror is kept (per #10736 AC11 — no boot-transcript proof yet that AGENTS.md loads before AGENTS_STARTUP.md). Defensible conservative call — but this PR exists because the mirror drifted (8 vs 9 gates). Keeping it preserves the recurring-drift surface with no mechanical guard for the next divergence, and the retirement condition has no path-to-capture. Worth a follow-up: either a CI drift-guard asserting AGENTS_STARTUP §3.1AGENTS.md §critical_gates (kills the drift class mechanically), or a ticket to capture the boot-transcript evidence so the mirror can finally become a pointer. Not blocking — the PR correctly satisfied the "sync + document why it stays" AC option.

Rhetorical-Drift Audit (§7.4):

  • PR description: framing matches the diff — I verified the MCP-inventory, 9-gate-sync, dead-ref, and worktree-config claims against origin/dev; no overshoot.
  • Anchor & Echo: N/A — docs change, no JSDoc.
  • [RETROSPECTIVE] tag: N/A — none authored.
  • Linked anchors: #13042's agent-harness.md verified present; #10736 AC11 accurately characterized.

Findings: Pass.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None.
  • [TOOLING_GAP]: None — author correctly used manual gh pr checkout per the #13052 checkout_pull_request operator-tree-mutation advisory.
  • [RETROSPECTIVE]: Single-sourcing a drift-prone inventory (MCP servers ← package.json ai:mcp-server-*) instead of a hand-maintained list is the right anti-drift pattern; the residual §3.1 mirror is the one hand-synced surface left (see Depth Floor).

🎯 Close-Target Audit

  • Close-targets identified: #13043 (via newline-isolated Resolves #13043).
  • #13043 confirmed not epic-labeled (labels: bug, documentation, ai); Related: #13042 is correctly non-closing.

Findings: Pass.


🔗 Cross-Skill Integration Audit

  • Predecessor step: the new .agents/workflows/ skill #3 + §4 pointers reference the existing agent-harness.md (verified present on dev) — no latent gap.
  • AGENTS_STARTUP.md workflow-skills pointer: the dead AGENTS.md §21 Workflow-skills reference was pruned into the named-anchor handoff — consistent.
  • No new MCP tool / convention requiring a reciprocal doc.

Findings: All checks pass — no integration gaps.


🧠 Turn-Memory / Substrate-Load Audit

  • AGENTS_STARTUP.md is in the /turn-memory-pre-flight IN-SCOPE list. The PR body documents the decision-tree application: boot/read-on-demand (not per-turn-loaded), rewrite disposition, net line reduction, mission/lifecycle detail moved to skills/.agents/workflows/ rather than added as always-loaded rule body. Load-effect correctly audited.

Findings: Pass.


🧪 Test-Execution & Location Audit

  • Docs-only change (one .md file) — no tests required (guide §7.5.3). Author's boot-path link sweep + git diff --check is the appropriate L1 evidence; I independently V-B-A'd the introduced references against origin/dev.

Findings: No tests needed (docs change); references independently verified.


N/A Audits — 📑 📡 🛂 🔌

N/A across listed dimensions: docs-only boot-substrate refresh — no public/consumed code surface (Contract Ledger), no OpenAPI tool descriptions (MCP budget), no major new abstraction (Provenance), no wire-format change.


📋 Required Actions

No required actions — eligible for human merge.

(The Depth Floor item — a CI drift-guard or boot-transcript-capture ticket for the §3.1 mirror — is a non-blocking suggestion, not a gate on this PR.)


📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 100 — I actively considered (a) MCP-inventory accuracy, (b) §critical_gates mirror fidelity, and (c) named-anchor correctness, and confirmed all align with the current substrate; the get_context_frontier deference-gate removal actively improves alignment with §swarm_topology_anchor.
  • [CONTENT_COMPLETENESS]: 95 — 5 points deducted because the body is otherwise a complete Fat-Ticket (Evidence / Deltas / Turn-Memory-Pre-Flight / Test-Evidence) but leaves the recurring-mirror-drift surface undocumented as a follow-up (a one-line "follow-up: drift-guard the mirror" would have closed the loop).
  • [EXECUTION_QUALITY]: 100 — docs-only; every introduced reference V-B-A-verified against origin/dev (agent-harness.md present, ai:mcp-server-* present, chrome-devtools = 0), CI green, no defects. I considered dead-ref / wrong-anchor / dangling-file-reference and confirmed none apply.
  • [PRODUCTIVITY]: 100 — I considered whether any of #13043's three ACs (inventory single-source, §0 mirror decision, dead-ref fix) were left incomplete or whether the boot-only scope was violated; all three are satisfied and scope is honored (plus an adjacent worktree-config drift fixed).
  • [IMPACT]: 60 — substantive: corrects the cold-boot substrate every harness session reads + removes a boot-level deference gate; below higher tiers because it's substrate-maintenance, not framework architecture or a major subsystem.
  • [COMPLEXITY]: 30 — Low: single markdown file, net −6 lines, no code paths; the cognitive load is in verifying references against the live substrate, not in the change itself.
  • [EFFORT_PROFILE]: Maintenance — routine substrate-staleness correction at a high-correctness bar (boot substrate) but low structural complexity.

Clean refresh — approved and eligible for your merge, @tobiu. Well done under the Fable-down reviewer-gap pressure; the deference-gate removal on get_context_frontier is a quiet but real improvement. The only thing I'd watch is the §3.1 mirror's recurring drift surface (Depth Floor) — a follow-up, not a blocker. 🖖 — Grace
