Ecosystem Update - 2026-06-21

TL;DR

• Safe Quick Win implemented: repaired existing Stop-gate scripts to emit the current Codex decision: "block" / reason shape instead of legacy stopReason.
• No new hook wiring, agent imports, skill imports, plugin hooks, native memories, or binary upgrade was safe to auto-apply under the harness limits.
• Main near-term work remains a deliberate stable Codex upgrade/smoke plus a constrained Stop-gate wiring pilot now that the local scripts are output-shape compatible.

Quick Wins

Auto-Implemented

• Backed up config.toml, hooks.json, all agent TOMLs, completion_gate.py, codex_review_gate.py, and what_would_chad_do.py to /Users/chadsimon/.codex/backups/2026-06-21/.
• Updated /Users/chadsimon/.codex/bin/completion_gate.py so failed Stop-time checks return {"decision":"block","reason":"..."}.
• Updated /Users/chadsimon/.codex/bin/codex_review_gate.py so R3/R4 adversarial review continuations return {"decision":"block","reason":"..."}.
• Updated /Users/chadsimon/.codex/bin/what_would_chad_do.py so reflection continuations return {"decision":"block","reason":"..."}.
• Verification passed: python3 -m py_compile .codex/bin/completion_gate.py .codex/bin/codex_review_gate.py .codex/bin/what_would_chad_do.py.
• Verification passed: parsed /Users/chadsimon/.codex/config.toml with tomllib and /Users/chadsimon/.codex/hooks.json with json.
• Verification passed with existing notes: TERM=xterm-256color codex --strict-config doctor --summary --ascii returned 0 fail; notes were update availability, unrestricted sandbox/network posture, rollout storage size, and two thread-state warnings.

Build Queue

• Stable Codex 0.141.0 upgrade and smoke (Codex-md) - https://github.com/openai/codex/releases - PATH Codex is 0.140.0, official latest stable is 0.141.0, and the app bundle has 0.142.0-alpha.1; upgrade deliberately and smoke hooks, plugin routing, MCP discovery, and doctor output before changing PATH.
• Stop-gate wiring pilot after output-shape repair (hook) - https://developers.openai.com/codex/hooks#stop; https://howborisusesclaudecode.com/ - Existing Stop-gate scripts now emit the documented shape, but adding them to hooks.json should be a controlled pilot because Stop blocks create continuation prompts.
• apply_patch PreToolUse/PostToolUse coverage audit (hook) - https://developers.openai.com/codex/hooks#pretooluse - Official docs say file edits through apply_patch can be matched as apply_patch, Edit, or Write; current harness guards and ledgers are Bash-only.
• Probe-and-refine repository guidance eval (research) - https://arxiv.org/list/cs.SE/recent - The new "Probe-and-Refine Tuning of Repository Guidance for Coding Agents" paper is directly aligned with AGENTS.md and skill gotcha maintenance, but policy-doc edits are not Quick Wins.
• Clarification uncertainty adapter for R5 routing (research) - https://arxiv.org/list/cs.AI/new - "Uncertainty Decomposition for Clarification Seeking in LLM Agents" suggests a lightweight way to separate action confidence from request ambiguity; useful for prompt preflight and R5 escalation, but needs eval before runtime use.
• Solver/certificate narration-gap check (research) - https://arxiv.org/list/cs.AI/new - "Analyzing the Narration Gap in LLM-Solver Loops" supports adding narration robustness checks around formal verifier outputs before the harness treats solver-backed claims as user-ready truth.

Research

• AutoPass: Evidence-Guided LLM Agents for Compiler Performance Tuning - Evidence-guided iteration maps to the existing verification-ledger pattern, especially for performance-sensitive build loops.
• N-Version Programming with Coding Agents - Worth tracking for bounded parallel candidate generation with reviewer/validator arbitration.
• Contagion Networks: Evaluator Bias Propagation in Multi-Agent LLM Systems - Relevant to reviewer-committee bias and why independent evidence beats repeated peer agreement.
• RACL: Reasoning-Agent Control Layers for Continuous Metaheuristic Learning - Relevant to bounded control layers for /auto, but too abstract for an immediate harness patch.
• ScaffoldAgent: Utility-Guided Dynamic Outline Optimization for Open-Ended Deep Research - Useful for research-digest planning heuristics, not for core coding runtime yet.

Rejected

• Automatic Codex binary upgrade - rejected: updates affect the active harness and need deliberate smoke; current doctor already reports 0.141.0 available.
• Switch PATH to app-bundled 0.142.0-alpha.1 - rejected: alpha runtime adoption conflicts with the global posture against under-development features.
• Wire completion_gate.py or codex_review_gate.py into hooks.json today - rejected: output shape is now repaired, but new Stop blocking behavior needs a controlled pilot and explicit target hook entry.
• Enable native Codex memories - rejected: current posture deliberately uses omni-mem and keeps native memories disabled.
• Enable features.plugin_hooks globally - rejected: plugin hook trust remains disabled until a trust review says otherwise.
• Install cc-safe-setup, GateGuard, or community hook bundles wholesale - rejected: outside skills/hooks require codex-skill-audit --strict, overlap existing guards, and would add new scripts or hook wiring.
• Import Boris/Claude skill bundles wholesale - rejected: useful as reference material, but runtime must stay Codex-owned and outside skills require audit.
• Edit AGENTS.md as a Quick Win - rejected: constitutional policy docs are outside the Quick Win mutation boundary.
