Prismer execution contract
This is the uniquely named prismer-github skill, adapted from Hermes.
Use the actual tools exposed by the executing host; examples using terminal,
process, delegate_task, vision_analyze or browser_* are not tool registrations.
Missing dependencies do not hide this skill. Report command startup, version,
account/permissions and task-specific live verification separately. Use task-owned
artifact paths and existing user authorization; do not change shared accounts,
Runtime/provider configuration, global security settings or unrelated work.
See NOTICE.md and LICENSE for resource provenance. Runtime availability and
upstream-entry suppression are owned by the integration layer.
GitHub
Work GitHub end to end with the gh CLI (REST fallback where noted): auth,
issues, the PR lifecycle, issue-to-PR delivery, code review, and repo
management. This skill consolidates six former skills; each workflow lives
complete in its reference file — ALWAYS read the matching reference before
starting that workflow, the body below only routes.
Routing
| Task | Read first |
|---|---|
| Auth broken / new machine / token or SSH setup / gh login | references/auth.md |
| Create, triage, label, assign, close issues | references/issues.md |
| Branch, commit, open PR, watch CI, merge | references/pr-workflow.md |
| Carry an ISSUE to a verified PR (full delivery loop) | references/issue-to-pr.md |
| Review someone's PR: diffs, inline comments, verdict | references/code-review.md |
| Clone/create/fork repos, remotes, releases | references/repo-management.md |
Supporting assets: scripts/gh-env.sh + scripts/git-credential-token.py
(auth helpers), templates/ (PR bodies, bug report, feature request),
references/ci-troubleshooting.md, references/conventional-commits.md,
references/github-api-cheatsheet.md, references/review-output-template.md.
Core discipline (applies to every workflow)
- Before use, resolve SKILL_ROOT to this installed directory and run
python3 "$SKILL_ROOT/scripts/ensure-gh.py". Missing gh is automatically installed within existing host permissions, then version and auth are checked separately. Readreferences/auth.mdfor account and target repository permission gates. - Prefer
ghover raw REST; drop togh apionly for endpoints the porcelain lacks (the cheatsheet lists them). - Never report CI green without checking
gh pr checksyourself; never claim merged without verifyingstate,mergedAt. - Read full context before writing:
gh issue view --comments/gh pr view --comments— decisions live in threads, not titles. - Sweep for duplicates before creating anything:
gh pr list --search/gh issue list --search.
Verification
- The workflow's own reference file defines done for that task.
- Cross-cutting: every claim about remote state (CI, merge, release,
issue state) is backed by a fresh
ghread, never memory.
