[4.8.0] -- 2026-05-19

Codex CLI parity refresh against Codex 0.129.0+. Docs + plugin manifest + marketplace structure. No detection / rule / hook code changes; 380 tests still passing.

Docs cleanup (Phase A):

• README and tailtest.com/docs/codex install sections no longer instruct users to set [features].codex_hooks = true. Hooks reached GA in Codex 0.129.0 (default-on); the legacy alias still works but emits a deprecation warning every session. Older-version subsection added that documents the post-deprecation [features].hooks = true flag for users pinned to pre-0.129.0 releases.
• scripts/init.sh feature-flag check rewritten. Silent on current Codex defaults; emits a clean deprecation notice only when the user's ~/.codex/config.toml still has the legacy codex_hooks key. Header comment updated to reference the new key.

Plugin manifest + marketplace structure (Phase B):

• .codex-plugin/plugin.json updated to current Codex spec form: hooks and skills as string paths instead of object/array forms. Version bumped to 4.8.0. Added interface block (displayName, descriptions, capabilities, defaultPrompt, brandColor) so the plugin renders properly in Codex's /plugins browser and any marketplace listing.
• New .agents/plugins/marketplace.json declares this repo as a single-plugin marketplace named avansaber-tailtest. Users can now register the plugin in one command: codex plugin marketplace add avansaber/tailtest-codex. The existing git clone + init.sh flow continues to work unchanged.
• Important honest framing: marketplace install replaces only the git clone step. Users still need to run init.sh per project for hooks to fire, because Codex's plugin_hooks feature (which would auto-register plugin-bundled hooks) is still in development upstream. When that ships stable, init.sh will be retired. Until then, both install paths require the per-project init step.

Skills polish (Phase D):

• All 5 skill files in skills/tailtest/ got their frontmatter descriptions rewritten to the "When the agent needs to (1)... (2)... (3)..." pattern used by marketplace-quality plugins. This improves how the skills score in Codex's @-mention picker against natural-language user phrases. File bodies are unchanged.
