Ecosystem Update — 2026-06-16

TL;DR

• Auto-implemented the safe Quick Win: upgraded Codex CLI from 0.133.0 to 0.140.0, which picks up the June 15 CLI release line including /usage, /import, permanent deletion commands with confirmations, MCP reliability fixes, and large-session responsiveness work.
• Today's strongest external pattern is not more orchestration; it is evidence-linked evaluation: reusable traps/rubrics, semantic skill-risk judging, phantom-reference audits, and trace-level behavior analysis.
• The upgraded built-in doctor is useful but now exposes local state debt: rollout files and the state DB disagree, and TERM=dumb causes a terminal check failure in non-interactive runs.

Quick Wins

Auto-Implemented

• Codex CLI upgrade — codex update completed successfully and moved PATH codex from codex-cli 0.133.0 to codex-cli 0.140.0.
• Backups — wrote pre-change copies to ~/.codex/backups/2026-06-16/ for config.toml, hooks.json, and all custom agent TOMLs.
• Verification — python3 -m json.tool ~/.codex/hooks.json passed; python3 ~/.codex/bin/codex_config_posture.py --mode warn passed; codex --version reports codex-cli 0.140.0; codex doctor --json completed with overallStatus=fail only from pre-existing/local environment findings: state.rollout_db_parity warning and terminal.env failure under TERM=dumb; codex-runtime-doctor confirms 0.140.0 but times out inside its nested official-doctor subcheck after 45s.

Build Queue

• Rollout DB parity repair/reindex (hook/Codex-md) — official doctor now reports rollout files and state DB thread inventory differ, with the active file scan capped at 10,000 files and 8,305 missing active DB rows. Build a non-destructive audit/reindex command before attempting any cleanup.
• Forge-harness-style phantom-reference audit (skill) — https://github.com/hesreallyhim/awesome-claude-code/issues/1961 — Adapt the concept, not the plugin: run source-grounding checks over AGENTS.md, SKILL.md, and custom agent TOMLs so claims cite local files/lines instead of becoming stale runtime lore.
• SkillVetBench-style semantic skill-risk vetting (skill) — https://arxiv.org/abs/2606.15899 — Extend codex-skill-audit --strict with instruction-layer checks for prompt injection, memory poisoning, and cross-agent risk before trusting external skills.
• Human-on-the-Bridge eval intelligence pack (agent-pattern) — https://arxiv.org/html/2606.16871v1 — Planning-gate already has verifier structure; add reusable trap/rubric packs and fallback policies for recurring autonomous-runtime evals.
• Agent genome trace analyzer (research/agent-pattern) — https://arxiv.org/html/2606.15579v1 — Consider a small offline analyzer that classifies traces into Explore/Plan/Execute/Verify sequences and flags closure without verification.
• CoAgent-style concurrency-control intake (research/agent-pattern) — https://arxiv.org/abs/2606.15376 — Relevant to local multi-agent dispatch, but should start as a design note against existing task envelopes and file-scope constraints.

Research

• Human-on-the-Bridge: Scalable Evaluation for AI Agents — Strong fit for reusable evaluation intelligence: red-team traps, juror personas, scoring guidelines, audit rules, and fallback policies.
• TokenPilot: Cache-Efficient Context Management for LLM Agents — Useful for future compaction/runtime work because it frames prompt-cache preservation as a first-class constraint.
• SkillVetBench: LLM-as-Judge for Multi-Dimensional Security Risk Evaluation in Open-Source LLM Agent Skills — Directly applicable to the existing external-skill trust gate.
• Your Agent Has a Genome: Sequence-Level Behavioral Analysis and Runtime Governance of LLM-Powered Autonomous Agents — Useful framing for lightweight trace analysis over Codex task loops.
• CoAgent: Concurrency Control for Multi-Agent Systems — Worth tracking for file-claim and conflict-avoidance design, but not a quick win.
• Minimal Oversight: Uncertainty-Aware Governance for Delegated AI Systems — Relevant to keeping review pressure high only where uncertainty warrants it.

Already Have

gpt-5.5 default model, high reasoning effort, approval_policy = "never", danger-full-access, prompt telemetry off, hooks enabled, plugin hooks disabled, OpenAI developer docs MCP, omni-mem MCP, PreToolUse Bash guard, PostToolUse verification/failure-context hooks, UserPromptSubmit route classifier, Stop/PreCompact omni-mem hooks, read-only reviewer/planner/explorer/validator agents, workspace-write worker/chad-twin agents, planning-gate, auto runtime, codex-session-search, codex-skill-audit strict gate, execpolicy rules with codex execpolicy check, browser/chrome/computer-use plugins, official document/spreadsheet/presentation/pdf plugins, Codex CLI 0.140.0.

Rejected

• Claude Classroom live file-claim board — Requires repo-local hook installation, a CLI launcher, and shared .git state. Useful idea, but not safe as an automatic global harness change.
• EstreGenesis / Constellation live A2A board — Requires new plugin installs and a local WebSocket server. This crosses the anti-overengineering gate for today's harness update.
• Wholesale import from community skill catalogs — agent-skills, awesome-agent-skills, and awesome-codex-cli are discovery surfaces, not trust roots. Continue using codex-skill-audit --strict before adoption.
• Enable plugin hooks globally — Still rejected because plugin_hooks = false is an intentional trust boundary.
• Edit AGENTS.md as a Quick Win — Prohibited by the ecosystem-update hard limits and by the runtime ownership contract.
• Run codex delete or cleanup session state automatically — New 0.140.0 deletion support is useful, but deleting local rollout/session data is destructive and must be a separate explicit task.
• Adopt features.memories = true — Native Codex memories remain off intentionally while omni-mem is the active memory system.
