What it does

Prismer GitHub is an agent skill from Prismer-AI/PrismerCloud. GitHub via gh CLI: PRs, issues, reviews, repos, auth.

Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. The skill folder holds 24 other files, including scripts and reference files (for example `NOTICE.md`, `references/auth.md` and `references/ci-troubleshooting.md`).

It sits in Development. It works with GitHub. The licence is MIT.

When your agent uses it

  • Development work in your project

Example prompts

  • “/prismer-github”

Requirements

  • Python 3
  • A Bash shell

What it can do on your machine

Read from SKILL.md and the folder at commit e5d9444. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 5 files in scripts/ (Python and Shell, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • gh
    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Prismer GitHub loads about 862 tokens when it runs, and up to ~20k if it reads all its reference files. Until then it costs about 17 tokens; SKILL.md has 357 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~17
When it runs · the whole SKILL.md, loaded when a task matches
~862
With references · SKILL.md plus every file in references/, read only if the agent opens them
~20k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

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

TaskRead first
Auth broken / new machine / token or SSH setup / gh loginreferences/auth.md
Create, triage, label, assign, close issuesreferences/issues.md
Branch, commit, open PR, watch CI, mergereferences/pr-workflow.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. Read references/auth.md for account and target repository permission gates.
  • Prefer gh over raw REST; drop to gh api only for endpoints the porcelain lacks (the cheatsheet lists them).
  • Never report CI green without checking gh pr checks yourself; never claim merged without verifying state,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 gh read, never memory.
