Ecosystem Update — 2026-05-11

May 11, 2026 · generated by the ecosystem-update Claude Skill

TL;DR

Two safe hook Quick Wins were implemented: the existing Bash pre-tool guard is now active, and existing PostToolUse helpers now record verification commands and surface failed Bash output.
Today's useful external signal is still governance and verification, not more orchestration: Codex hooks, exec policies, design conformance checks, and formal coordination verification are the recurring patterns.
The current harness already has most high-value primitives: GPT-5.5, live web search, hooks, omni-mem lifecycle hooks, read-only reviewer agents, plugin support, OpenAI docs MCP, and parallel-safe docs MCP calls.

Quick Wins

Item	Source	Type	Impact	Effort	Action
Existing PreToolUse Bash catastrophe guard	https://developers.openai.com/codex/hooks#pretooluse, https://github.com/shanraisshan/codex-cli-best-practice/blob/main/best-practice/codex-hooks.md, https://agenticcontrolplane.com/blog/codex-cli-hooks-reference	hook	3	1	Auto-implemented `PreToolUse` wiring for existing `/Users/chadsimon/.codex/bin/pre_tool_guard.py`
Existing PostToolUse verification ledger and failure context	https://developers.openai.com/codex/hooks#config-shape, https://github.com/shanraisshan/codex-cli-best-practice/blob/main/best-practice/codex-hooks.md	hook	2	1	Auto-implemented `PostToolUse` wiring for existing `/Users/chadsimon/.codex/bin/edit_verify_async.py` and `/Users/chadsimon/.codex/bin/tool_failure_context.py`

Auto-Implemented

Backed up config.toml, hooks.json, and all agent TOMLs to /Users/chadsimon/.codex/backups/2026-05-11/ before editing.
Updated /Users/chadsimon/.codex/hooks.json with a Bash PreToolUse hook that runs the existing catastrophic-command guard.
Updated /Users/chadsimon/.codex/hooks.json with Bash PostToolUse hooks that record verification commands and surface concise failure context.
Verified hooks.json parses with python3 -m json.tool.
Verified config.toml and all /Users/chadsimon/.codex/agents/*.toml parse with Python tomllib.
Smoke-tested pre_tool_guard.py: benign Bash input exits 0; git reset --hard exits 2 with the block reason.
Smoke-tested edit_verify_async.py and tool_failure_context.py with representative PostToolUse payloads.

Build Queue

Execpolicy rules profile for destructive shell prefixes (hook) — https://github.com/shanraisshan/codex-cli-best-practice/blob/main/README.md and https://developers.openai.com/codex/config-reference — Codex now supports command execution policies and named permission profiles. The harness has a Python pre-tool guard, but no Starlark rules layer; build only if the current guard misses real recurring shell-risk cases.
Stop-time completion gate hook wiring (hook) — local existing scripts plus https://developers.openai.com/codex/hooks#config-shape — /Users/chadsimon/.codex/bin/completion_gate.py, what_would_chad_do.py, and codex_review_gate.py exist, but wiring them as global Stop hooks can run tests or reviews on every turn. This needs an explicit runtime decision rather than a daily Quick Win.
Design conformance trace check (research) — https://arxiv.org/abs/2605.07909 — The OpenTelemetry trace-conformance idea maps to the existing OTEL config and could become a bounded eval for long-running harness behavior drifting from design contracts.
TraceFix-style protocol verifier (research) — https://arxiv.org/abs/2605.07935 — TLA+-checked coordination protocols are interesting for governed multi-agent packets, but this is too heavy for the current harness without a narrow failure case.

Research

TraceFix: Repairing Agent Coordination Protocols with TLA+ Counterexamples — Relevant to formalizing multi-agent packet topology before execution, especially for R3/R4 governed work.
Evaluating Design Conformance Through Trace Comparison — Useful for checking runtime traces against intended design behavior using the OTEL surface already configured locally.
Retrieval-Conditioned Topology Selection with Provable Budget Conservation for Multi-Agent Code Generation — Reinforces the local direction of repo-context preflight before choosing orchestration depth, but implementation would require a benchmark.
Active Learning for Communication Structure Optimization in LLM-Based Multi-Agent Systems — Relevant to future route-manifest tuning, not an immediate harness change.
To What Extent Does Agent-generated Code Require Maintenance? An Empirical Study — Supports maintainability scoring in evaluate/refactor, already queued from the prior run.

Already Have

Rejected

Wholesale import from awesome-claude-code — rejected: the source is still in an index rebuild/TODO state, and the Codex contract requires copying or rewriting useful Claude behavior into Codex-owned surfaces.
Native Codex memories as an immediate replacement — rejected: current policy makes omni-mem the default memory workflow; native memories need an explicit pilot, not a silent switch.
Upgrade to 0.131 alpha releases — rejected: latest visible 0.131 tags are alpha/pre-release builds. Keep this as a release-watch item, not a Quick Win.
Global Stop-time test/review hooks as a Quick Win — rejected: useful scripts exist, but automatic tests/reviews on every stop are too operationally heavy for a daily safe update.
Deploying the website — rejected per user instruction; the wrapper will render and deploy after this run finishes.
