chore: vendor Ponytail as repository-local Codex plugin - #10
Merged

Conversation
Keep Ponytail's complete Codex runtime payload in third_party/ponytail and expose it through the repository marketplace at .agents/plugins/marketplace.json. The vendored payload preserves Ponytail's six skills and executable lifecycle hooks so Codex runs the standard SessionStart, UserPromptSubmit, and SubagentStart behavior, including full-mode default, mode persistence, and subagent propagation. The only local packaging adaptation is cosmetic: use Ponytail's upstream SVG logo instead of its large PNG in the manifest. Record the exact upstream source revision, add setup scripts that install the local plugin through Codex's normal plugin system, and add update scripts that refresh the vendored runtime payload from DietrichGebert/ponytail main. Ponytail updates therefore become explicit, reviewable repository changes instead of loading unreviewed upstream main directly at runtime.

Vendors Ponytail's standard Codex plugin runtime into this repository and exposes it through a repository-local Codex marketplace.
Layout
third_party/ponytail/- canonical project copy of the Ponytail plugin.agents/plugins/marketplace.json- local marketplace exposingponytail@llama-cpp-localscripts/setup-ponytail.ps1/.sh- install the local plugin through Codexscripts/update-ponytail.ps1/.sh- refresh the vendored copy from upstreamdocs/agents/ponytail.md- integration/update documentationFull Ponytail behavior retained
The vendored payload contains the upstream six skills and lifecycle hooks:
The project does not reimplement or flatten Ponytail into ordinary
.agents/skills; Codex still loads it as a real plugin.Upstream provenance
Initial vendored revision:
DietrichGebert/ponytail@e3ba2aa6f1e6f0bc4d69eb09c9f0d0a93af56156third_party/ponytail/UPSTREAM_REVISIONrecords the source commit.The executable hooks and skill files are copied unchanged. The only packaging adaptation is cosmetic: the local manifest uses Ponytail's upstream SVG logo rather than its large PNG.
Updating
Run the project updater, inspect the resulting hook/skill diff, then commit it. This makes executable plugin updates reviewable repository changes instead of consuming upstream
mainlive.Codex still requires the user to review/trust Ponytail's hooks through
/hooks; the setup scripts do not bypass that security boundary.
