Ecosystem Update - 2026-05-23

Highlights

One safe harness delta was found and implemented: SessionStart hooks now cover the official compact source in addition to startup|resume|clear
Today's community signal is mostly orchestration packaging, context packets, run ledgers, and scoped worker handoffs; the local setup already has the core primitives through auto, planning-gate, AgentOps contract checks, and role-specific agents
No website deployment was performed; this run only touched Codex harness files plus the ecosystem report/state

SessionStart compact matcher coverage hook

Extend the two existing SessionStart matchers in ~/.codex/hooks.json from `startup

Context-packet/run-ledger compatibility intake agent-pattern

github.com/douglasmonsky/codex-orchestrate

https://github.com/douglasmonsky/codex-orchestrate and https://github.com/ZypherHQ/agent-orchestration-skill - Both packages emphasize root-only routing metadata, compact worker packets, terminal lifecycle states, and handoff validation. Do not install wholesale; compare their packet/ledger schemas against the existing AgentOps task envelope and planning-gate implementation
Feature-specific subagent review pass agent-pattern

github.com/shanraisshan/codex-cli-best-practice

A narrow follow-up could identify one or two genuinely recurring domains that deserve dedicated TOML agents instead of expanding the roster generically
Skill trigger and Gotchas audit skill

github.com/shanraisshan/codex-cli-best-practice

https://github.com/shanraisshan/codex-cli-best-practice - Current skills are numerous and mostly mature; a bounded audit should check whether high-use skills have sharp trigger descriptions and concise failure-mode notes without rewriting bodies

Tier 2 was skipped because the previous run fetched research at 2026-05-22T10:37:39Z, and this run started at 2026-05-23T10:30:39Z, inside the skill's 24-hour skip window.
No new research papers were fetched in this run.

Items reviewed and explicitly declined this cycle, with the reason. Curation discipline matters more than coverage.

Edit|Write matcher-only hook wiring - Official docs and community hook catalogs confirm apply_patch/Edit/Write matcher support, but the existing local edit_verify_async.py and tool_failure_context.py scripts intentionally return unless tool_name == "Bash". Changing only the matcher would be a no-op; any file-edit hook coverage needs a real script design and belongs outside Quick Wins.
Global AGENTS.override.md adoption - Official docs support overrides, but a global override could silently shadow the byte-identical ~/.codex/AGENTS.md and ~/AGENTS.md contract. Treat this as an explicit policy decision, not an automatic harness tweak.
Wholesale install of codex-orchestrate, agent-orchestration-skill, or am-will/codex-skills - Conflicts with the Codex-owned runtime rule and duplicates existing auto/planning-gate/orchestrate-local primitives without proving those primitives are insufficient.
llm-council or multi-provider planning UI - Requires extra providers/API keys and a web UI; overengineered for the current local harness.
read-github, markdown-url, Context7, or alternate browser skills - Already covered well enough by live web, OpenAI docs MCP, Browser/Chrome plugins, and local rg/GitHub reads.
