Ecosystem Update - 2026-06-24

TL;DR

• No safe harness Quick Win was auto-applied today; the strongest hook idea needs script-level support before changing hooks.json.
• Current Codex setup already has the high-value baseline: live web search, OpenAI docs MCP, omni-mem MCP, bounded subagents, read-only reviewers, Bash safety guard, post-command verification ledger, route classifier, stop-time memory/completion gates, strict skill audit, and AgentOps contract checks.
• Today's useful new signal is research-heavy: verifier/controller harnesses, memory context reinstatement, coordination noise-floor tests, and goal/dialogue runtime modeling are worth intake, but not direct runtime mutations.

Quick Wins

Auto-Implemented

• None. Report and state files only.

Build Queue

• Edit-tool evidence hook design (hook) - https://developers.openai.com/codex/hooks - Official matcher docs support apply_patch, Edit, and Write, but the local edit_verify_async.py and tool_failure_context.py intentionally ignore non-Bash tools. Build a separate edit-evidence recorder or a tested script extension before widening PostToolUse matchers.
• Skill catalog selective audit pass (skill) - https://github.com/VoltAgent/awesome-agent-skills and https://github.com/heilcheng/awesome-agent-skills - New/active skill directories reinforce third-person descriptions, progressive disclosure, no absolute paths, and scoped tools. Current setup already has many skills plus codex-skill-audit --strict; the next value loop is one domain-specific audit, not wholesale import.
• Goal-runtime invalidation audit (agent-pattern) - https://arxiv.org/abs/2606.23797 - Goal-oriented dialogue/runtime work maps to local features.goals, /auto objective state, and contract closure. Audit whether resumed goals correctly invalidate stale assumptions before dispatching long-running work.
• Verifier budget controller spike (research) - https://arxiv.org/abs/2606.23983 - Maestro Order's decompose/ensemble/verify/recurse primitives resemble existing planning-gate and reviewer barriers. A bounded spike could compare current fixed gates against a cost-aware verifier allocation rule without adding a new orchestration layer.
• Coordination noise-floor eval adapter (research) - https://arxiv.org/abs/2606.20695 - Paired noise-floor evaluation could make multi-agent gains harder to overclaim. Useful as an eval harness for max_threads, reviewer committees, and planner/worker splits.

Research

• Maestro Order: A Model-Agnostic Orchestration Harness - Directly relevant to verifier allocation, but too broad to import; use only as an eval/control reference.
• RaMem: Contextual Reinstatement for Long-term Agentic Memory - Reinforces omni-mem's scene-context requirement and suggests future validity-aware retrieval checks.
• How Much Coordination Gain Is Real? A Paired Noise-Floor Protocol for Multi-Agent LLM Benchmarks - Useful for proving that multi-agent routing and reviewer barriers outperform single-agent baselines beyond noise.
• From Task-Guided Conversational Graphs to Goal-Oriented Dialogue Runtimes - Relevant to /auto goal state, resumability, and stale-context handling.
• MAS-PromptBench: When Does Prompt Optimization Improve Multi-Agent LLM Systems? - Watch item for prompt/profile tuning evals rather than immediate runtime change.

Rejected

• Widen PostToolUse matchers to apply_patch|Edit|Write immediately - rejected as a Quick Win because the current target scripts are Bash-specific; changing only hooks.json would either do nothing useful or pollute the verification ledger.
• Install external skill catalogs wholesale - rejected because outside skills require strict audit and domain need; the crawled catalogs are discovery sources, not trusted runtime input.
• Default all subagents to worktree isolation - rejected because current bounded subagent posture is intentional; broad worktree orchestration needs a scoped eval and cleanup model.
• Enable plugin_hooks globally - rejected because it expands hook trust surface without a concrete local need.
• Enable native Codex memories - rejected because omni-mem remains the default durable memory plane and duplicate memory systems create drift/privacy risk.
• Apply AGENTS.md policy changes as Quick Wins - rejected by skill hard limit; constitutional policy edits require explicit direction.
• Import Maestro Order as a new orchestrator layer - rejected as overengineering; extract eval ideas only.
