mcpkernel: Skill for Claude Code

.github/skills/test-and-merge/SKILL.md

test-and-merge is a skill for Claude Code, Codex from piyushptiwari1/mcpkernel. It costs 50 tokens per session (398 once invoked), scanned A, original, Apache-2.0.

A release-check workflow for testing a Python project, checking code style and documentation, and merging a development branch into the main branch when everything passes.

In plain words
What is it for?
Use it to inspect branches, run the full pytest test suite, run Ruff lint checks, review key documentation files and produce a merge status report.
Why use it?
It gathers the checks needed before a merge and prevents merging when tests, style checks or documentation checks fail.

Written for no agent in particular: nothing here depends on one.

This is piyushptiwari1/mcpkernel's own configuration. It tells Claude Code and Codex how to work on mcpkernel itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcpkernel configures →

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

test-and-merge 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 1mo 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

Test and Merge Workflow

When to Use

  • Validating that all tests pass before merging
  • Preparing the development branch for merge to main
  • Running comprehensive quality checks

Procedure

Step 1: Verify Branch State

git branch
git status
git log --oneline development..HEAD  # or HEAD..development

Step 2: Run Full Test Suite

python -m pytest tests/ -v --tb=short
  • All 106+ tests must pass
  • Zero failures, zero errors

Step 3: Run Lint Check

ruff check src/ tests/
  • No lint errors allowed

Step 4: Verify Documentation

  1. Check CHANGELOG.md has entries for recent changes
  2. Check README.md is current
  3. Check docs/USAGE.md matches current APIs

Step 5: Merge Decision

If ALL checks pass:

git checkout main
git merge --no-ff development -m "chore: merge development to main — all tests passing"
git checkout development

If ANY check fails:

  • Report failures with details
  • Do NOT merge
  • List what needs to be fixed

Step 6: Report

## Merge Report
- Tests: PASS/FAIL (count)
- Lint: PASS/FAIL
- Docs: UP TO DATE / NEEDS UPDATE
- Merge: COMPLETED / BLOCKED (reason)

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.
