kc-plugin-release

kc-plugin-release is a skill for Claude Code, Codex from iamcxa/kc-claude-plugins. It costs 42 tokens per session (484 once invoked), scanned A, original, MIT.

A set of instructions for maintaining a plugin feature or release pull request and updating released plugins in local Claude Code and Codex installations.

In plain words
What is it for?
It helps watch GitHub checks at an exact commit, detect failed or changed checks, and update local plugin installations after release.
Why use it?
It provides a repeatable handoff process for checking pull-request status and synchronizing a release after it is merged.

Skill for Claude CodeCodex

Written for Claude Code and Codex: ${CLAUDE_PLUGIN_ROOT} variable, but also reads ~/.codex or $CODEX_HOME. Also seen: reads .claude/ paths; mentions Claude Code; mentions Codex.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the kc-plugin-forge plugin — 5 skills shipped together

Install

Getting it into your agent

This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Claude Code
/plugin marketplace add iamcxa/kc-claude-plugins
Claude Code
/plugin install kc-plugin-forge

Made for: Claude Code, Codex.

Or install kc-plugin-forge, the plugin that ships this one along with the rest of its 5 skills.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

kc-plugin-release scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

KC Plugin Release

Keep the release handoff narrow and reproducible. In kc-claude-plugins, release-please owns version propagation, tags, changelogs, and marketplace metadata through release-please-config.json, .release-please-manifest.json, and .github/workflows/release-please.yml. This skill has no release-mutation authority.

Resolve PLUGIN_ROOT to the directory two levels above this SKILL.md. Claude Code may expose that directory as ${CLAUDE_PLUGIN_ROOT}; Codex should use the installed plugin root containing this skill. Do not assume a path under the user's home directory.

Feature and release PR checks

For a feature PR or the release-please PR, use the packaged exact-head watcher:

bash "$PLUGIN_ROOT/scripts/watch-pr-checks.sh" <pr-number> --repo iamcxa/kc-claude-plugins

The watcher uses the authenticated gh CLI directly, propagates failed checks, and rejects a result if the PR head changes while checks are running. A missing host-level monitor is not a reason to bypass the gate.

Post-release local sync

Only after the release PR is merged and the release exists:

  1. Use the non-Conductor main workspace for kc-claude-plugins.
  2. Update main and leave it clean. The helper refuses another branch, a dirty source, or a local head that differs from origin/main when that ref exists.
  3. Run:
bash "$PLUGIN_ROOT/scripts/post-release-sync.sh" <plugin> --repo <main-workspace>

The helper copies the released plugin into both ~/.claude/plugins/local/<plugin> and ~/.codex/local-plugins/<plugin>. It refuses to replace either destination when that destination is a symlink.

Do not edit release metadata, manufacture a tag, or rewrite marketplace data in this step. If release metadata is wrong, repair the release-please configuration in a separate feature PR and let its release PR publish the fix.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
