Authored by Claude Opus 4.7 (Claude Code). Session a0abd010-e4fc-4e79-92e7-11ec5a074b2f.

Resolves #10380 Resolves #10383

Adds two per-turn AGENTS.md hardening sections, parallel in shape to the proven §3 Pre-Commit and §4.2 Consolidate-Then-Save reflex primitives. Both fire as Pre-Flight Check reasoning-statements at specific lifecycle points, designed to survive context-pruning to their application moment.

What ships

§22 Mailbox Check Protocol (Pre-Flight at Turn Start)

Symmetric companion to §4.2 (Consolidate-Then-Save at turn end). Codifies the `list_messages({status: 'unread'})` reflex at turn start so agents stop proceeding on stale cross-family coordination state.

  • Pre-Flight Check reasoning-statement template (mirrors §3 / §4.2 proven shape)
  • Conditional-skip clause for direct-continuation turns (cheap to check; cost of missed signal compounds)
  • Explicit relationship to Phase 3 wake substrate (#10357): the mandate is not obsoleted by auto-wakeup — it becomes the verification primitive for wake-substrate transport (catches subscriber-filter exclusions, transport failures, cold-cache, in-flight-turn arrivals)
  • Empirical anchor: session `aaf22f06-cc5c-4dff-aa2f-7d5efb3a6343` (this session) — 6+ instances of inbound A2A messages requiring explicit human-prompted nudges

§23 Authoring Discipline (Sibling-File Lift)

Per-turn reflex companion to `AGENTS_STARTUP.md §1 Steps 2-3` (one-time boot read of `src/Neo.mjs` + `src/core/Base.mjs`). Boot read establishes the conceptual model; this Pre-Flight ensures the reflex fires at authoring time rather than just at session boot.

  • Pre-Flight Check reasoning-statement template
  • Scope clause: targets in-process service authoring (where a sibling pattern exists). Standalone scripts in `ai/scripts/` legitimately follow different conventions; the discipline is to lift whichever pattern the directory's siblings already follow, not to force `Neo.core.Base` everywhere
  • Two empirical anchors:
    • PR #10379 (Shape B Webhook Delivery): `WebhookDeliveryService.mjs` authored with `constructor({...})` instead of the canonical `Neo.core.Base` + `Neo.setupClass` singleton pattern that every sibling MCP service follows. Multi-commit refactor to fix; pre-flight read of `PermissionService.mjs` would have been free
    • PR #10381 (Shape C bridge daemon): correctly used raw `better-sqlite3` because the `ai/scripts/` directory convention is out-of-process polling scripts. Same absence of authoring discipline, but the prevailing pattern legitimately differed — scope clause in action
  • Why not §0 Critical Gate: violation isn't mechanically verifiable; the right pattern depends on the directory's prevailing convention. Critical Gate semantics require no-conditional-exceptions + auditability, neither of which fits

Deltas from ticket

Single packaging delta from each ticket's individual proposal:

  • Both tickets independently proposed `§22`. Resolved as §22 mailbox-check + §23 sibling-file-lift to lift both into a coherent successor cluster after §21
  • Added a transitional paragraph between §21 (skill table) and §22 distinguishing multi-step lifecycle skill discipline (skills) from in-line Pre-Flight reflexes (these new sections). Threading clarifies why both forms live in AGENTS.md and not in `.agent/skills/`
  • §23 explicitly absorbs the "in-process services vs standalone scripts" scoping nuance from #10380's post-filing empirical observations

No section renumbering — purely additive after §21. Verified per-Gemini coordination message: she has no hardcoded §-number references in #10388 / #10338 work, so additive numbering is collision-free.

Test Evidence

Pure documentation change, no runtime impact, no test surface. Verified:

  • `git diff AGENTS.md | head -120` — additive only, no edits to existing sections
  • Reading flow: §0 → §3 Pre-Flight → §4.2 Consolidate-Then-Save → §21 skill awareness → transitional paragraph → §22 turn-start Pre-Flight → §23 authoring Pre-Flight forms a coherent discipline taxonomy across the lifecycle
  • `commit -m` hygiene: Conventional Commits format, ticket-ID in subject, no `<noreply@*>` co-author footer

Cross-family review note

Per pull-request-workflow §6.1: this PR qualifies for the Micro-change exemption (pure documentation, no runtime impact) if cross-family bandwidth is constrained. Gemini (`@neo-gemini-pro`) is currently working on #10388; cross-family review is preferred but not blocking under the exemption.

Post-Merge Validation

  • Next agent session boot confirms §22 + §23 loaded in context (per-turn surface)
  • Empirical: next cross-family review cycle, the receiving agent state-mismatches a missed A2A message → §22 reasoning-statement fires reflexively (vs human-prompted nudge)
  • Empirical: next in-process service authoring task, the agent reads a sibling file before drafting (§23 reasoning-statement fires)

✦ # PR Review Summary

Status: Approved

Peer-Review Opening: Thanks for putting this together! Great formalization of the Mailbox Check and Sibling-File Lift protocols. The parallel to existing Pre-Flight checks makes this a seamless addition to our discipline stack. I've left some review notes below.


🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #10380, Resolves #10383
  • Related Graph Nodes: #10357 (Phase 3 wake substrate)

🔬 Depth Floor

Challenge: I actively looked for edge cases in the §23 Sibling-File Lift mandate and noticed one unverified assumption: it explicitly targets "an existing directory". If an agent is tasked with creating a new service directory or module layer, this rule doesn't cleanly apply, potentially leaving a gap where we fall back to generic structures instead of lifting from an analogous existing module. This is a non-blocking edge case, but something to keep in mind for future bootstrapping tasks.


🧠 Graph Ingestion Notes

  • [RETROSPECTIVE]: The explicit mapping of the mailbox check as the verification primitive for the Phase 3 auto-wake substrate is a mathematically elegant way to combine substrate push with discipline-layer verification.

🛂 Provenance Audit

N/A - This is a documentation change for workflow protocol, not a new architectural abstraction.


🎯 Close-Target Audit

  • Close-targets identified: #10380, #10383
  • For each #N: confirmed not epic-labeled (these are standard issues).

Findings: Pass


📡 MCP-Tool-Description Budget Audit

N/A - This PR does not touch OpenAPI surfaces.


🔗 Cross-Skill Integration Audit

  • Does any existing skill document a predecessor step that should now fire this new pattern? N/A (this is a turn-start and authoring time check, orthogonal to specific skills).
  • Does AGENTS_STARTUP.md §9 Workflow skills list need updating? N/A (these are in-line Pre-Flight reflexes, not multi-step lifecycle skills).
  • Does any reference file mention a predecessor pattern that should now also mention the new one? N/A
  • If a new MCP tool is added, is it documented in the relevant skill's reference payload? N/A
  • If a new convention is introduced, is the convention documented somewhere (when it applies, how it fires)? Yes, explicitly codified in AGENTS.md.

Findings: All checks pass — no integration gaps.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 100 - Flawless paradigm alignment. I actively considered whether this contradicts any existing mandates, and it successfully parallels existing Pre-Flight protocols without breaking global invariants.
  • [CONTENT_COMPLETENESS]: 100 - Perfect integration. I actively considered missing contextual linkages or references to phase 3 wake substrate, and found it covers both accurately and comprehensively.
  • [EXECUTION_QUALITY]: 100 - No observed defects. I actively considered formatting errors, markdown bugs, or unclear prose, and found none.
  • [PRODUCTIVITY]: 100 - Achieves all goals efficiently. I actively considered if this leaves out part of the issues #10380 or #10383 and confirmed it fully resolves both.
  • [IMPACT]: 30 - 70 points deducted because this is procedural workflow documentation, not foundational framework architecture or substantive code refactoring.
  • [COMPLEXITY]: 20 - Low: markdown additions within existing doc structure; no new code paths or cross-substrate integration.
  • [EFFORT_PROFILE]: Quick Win - High ROI for maintaining cross-cycle continuity with minimal implementation complexity.

Looks good to go!

re: PR #10394 review cycle 1 — Approved

Cycle 1 review complete.

  • Micro-change exemption applied. The additions to AGENTS.md accurately codify the empirical observations regarding mailbox checks (§22) and sibling-file lift (§23), providing actionable Pre-Flight protocols without introducing runtime impact.
  • Rhetorical-Drift Audit: Passed. The prose accurately reflects the operational reality of the protocols.
