Ecosystem Update - 2026-05-25

May 25, 2026 · generated by the ecosystem-update Claude Skill

TL;DR

No safe Quick Wins crossed the auto-implementation threshold today; the current harness already has the major Codex primitives from the daily sources.
Codex 0.133.0 is installed locally, matching the latest stable release; 0.134.0-alpha.3 exists but stays rejected under the runtime posture against global under-development features.
The only meaningful new Build Queue item is subagent lifecycle hook observability for SubagentStart/SubagentStop, which needs a small script before hooks can be wired safely.

Quick Wins

Item	Source	Type	Impact	Effort	Action
None	Daily crawl	n/a	n/a	n/a	No aligned candidate had Priority >= 2.0 without needing a new script, policy-doc edit, alpha upgrade, or broader runtime change

Auto-Implemented

None. Report and state artifacts were updated only; no harness behavior was changed.

Build Queue

Subagent lifecycle hook coverage (hook) - https://developers.openai.com/codex/hooks and https://github.com/openai/codex/releases/tag/rust-v0.133.0 - Codex now documents SubagentStart and SubagentStop hook events. Current hooks.json has PreToolUse, PostToolUse, SessionStart, UserPromptSubmit, Stop, and PreCompact, but no subagent lifecycle observability. Worth building as a small existing-script-backed tracer before any hook wiring.
Managed requirements profile constraints (Codex-md) - https://developers.openai.com/codex/config-reference#requirementstoml - Official config docs describe requirements.toml constraints for approval policies, sandbox modes, web search modes, hooks, and managed profiles. Current setup has local profiles and rules, but no managed requirements file. This is useful only if the power-user default needs enforceable enterprise-style guardrails.
Feature-specific reviewer expansion pass (agent-pattern) - https://github.com/shanraisshan/codex-cli-best-practice - Community guidance keeps emphasizing feature-specific subagents. Current setup already has generic, Python, TypeScript, validator, planner, explorer, worker, and reviewer agents; add more only when repeated project evidence shows a real gap.

Research

Event-B Agent: Towards LLM Agent for Formal Model Synthesis and Repair - Relevant as a verification-feedback repair loop pattern, but too formal-methods-specific to change the Codex harness today.
Autonomous LLM Agents & CTFs: A Second Look - Supports the existing split between general workers and specialized reviewers; no direct harness change needed.
Exploiting LLM Agent Supply Chains via Payload-less Skills - Already reflected in the local posture: strict outside-skill audit before trust, no wholesale skill installs, and no blind marketplace adoption.

Already Have

Codex CLI 0.133.0 stable, canonical [features].hooks = true, goals enabled, route classifier hook, pre-tool Bash guard, post-tool verification/failure hooks, SessionStart startup/resume/clear/compact coverage, Stop and PreCompact omni-mem hooks, read-only explorer/planner/reviewer/validator agents, Python and TypeScript reviewers, workspace-write worker, plugin support, OpenAI developer docs MCP with parallel tool calls, config profiles, Starlark exec policy rules, codex-skill-audit --strict, omni-mem as external memory, /go-style verify/simplify/close workflow, AGENTS.md policy kept concise and Codex-owned.

Rejected

Upgrade to Codex 0.134.0-alpha.3 - rejected: latest 0.134 builds are prereleases, and the runtime contract says not to enable under-development Codex features globally.
Wire SubagentStart/SubagentStop hooks immediately - rejected as a Quick Win: the skill forbids adding hooks that require a new script; using a placeholder command would add noise without evidence.
Enable plugin hooks automatically - rejected: still experimental/trust-sensitive in this setup, and prior state already rejected blind enablement.
Enable native Codex memories as a Quick Win - rejected: current setup intentionally uses omni-mem; flipping [features].memories would change memory authority without a fresh design decision.
Wholesale import Boris/Claude or Codex community skill packs - rejected: outside skills require strict audit, and the current local skill set already covers the recurring workflows.
Add auto-format hooks from community tips - rejected: needs repo-specific formatter detection and an existing script; otherwise it violates the no-new-script Quick Win limit.
