Included Skills8

contribute-pluginskills/contribute-plugin/SKILL.md

ALWAYS invoke this skill to operate the contribute plugin's own lifecycle — report its version and check or reconcile its agent-delivery footprint. Invoke it when this plugin's agents are missing from a session. NEVER commit marketplace-delivered agent definitions into a checkout.

contribution-standardsskills/contribution-standards/SKILL.md

Contribution standards for changes and reports sent to a repository the operator does not control. Loaded by other skills, not invoked directly.

manage-upstream-issueskills/manage-upstream-issue/SKILL.md

ALWAYS invoke this skill when continuing an open issue in a repository the operator does not control — answering a maintainer, adding evidence, or reporting the thread's current state. NEVER comment on or close an issue in such a repository without this skill.

manage-upstream-prskills/manage-upstream-pr/SKILL.md

ALWAYS invoke this skill when continuing an open pull request against a repository the operator does not control — answering review, publishing a revision, or reporting its current state. NEVER comment on or push to such a pull request without this skill.

open-upstream-issueskills/open-upstream-issue/SKILL.md

ALWAYS invoke this skill when filing an issue in a repository the operator does not control — a fork's upstream, or any base whose permission is READ, TRIAGE, or NONE. NEVER open an issue against such a repository without this skill.

open-upstream-prskills/open-upstream-pr/SKILL.md

ALWAYS invoke this skill when opening a pull request against a repository the operator does not control — a fork's upstream, or any base whose permission is READ, TRIAGE, or NONE. NEVER open a pull request against such a repository without this skill.

sync-forkskills/sync-fork/SKILL.md

ALWAYS invoke this skill when bringing a fork's default branch current with the repository it was forked from. NEVER bring a fork's default branch current with `gh repo sync`, `git merge`, or `git reset` run directly.

upstreamskills/upstream/SKILL.md

ALWAYS invoke this skill when starting a contribution to a repository the operator does not control, or when a contribution step needs that target and no live UPSTREAM_TARGET marker carries it — it resolves the upstream a fork came from, the head to push from, and the operator's permission on it. NEVER read the base or the operator's permission from a git remote, an account name, or a successful push.
