test-and-merge

test-and-merge is a skill for Claude Code from loopdive/js2. It costs 43 tokens per session (501 once invoked), scanned A, original, Apache-2.0.

A developer-run process for testing a change, merging it with the latest main branch, opening a pull request, waiting for CI, and merging it when checks pass. CI means automated checks run by the repository.

In plain words
What is it for?
Use it after implementing a fix to run equivalence tests, update the branch, push it, create a pull request, monitor CI, and self-merge when approved.
Why use it?
It provides a repeatable path from a completed fix to a verified merge and identifies when conflicts require senior help.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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 2mo 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 Pipeline

Devs run this themselves after implementing a fix. There is no separate tester agent — CI handles test262, and devs self-merge when CI passes.

Step 1: Merge main into branch

cd /workspace/.claude/worktrees/<branch>
git fetch origin && git merge origin/main
  • Clean merge: proceed
  • Conflicts in dashboard/, plan/, public/: git checkout --theirs <file>, then pnpm run build:planning-artifacts
  • Conflicts in src/**/*.ts: create [CONFLICT] task in TaskList for senior-developer. STOP.

Step 2: Run equivalence tests

npm test -- tests/equivalence.test.ts

All equivalence tests must pass. Any new failure = regression, fix before pushing.

Step 3: Push and open PR

git push origin <branch>
gh pr create --base main --title "fix(#N): <description>" --body "..."

Step 4: Wait for CI

Use a foreground blocking loop — keeps the agent occupied until CI result lands:

until [ -f /workspace/.claude/ci-status/pr-<N>.json ] && \
  [ "$(jq -r '.head_sha' /workspace/.claude/ci-status/pr-<N>.json)" = "$(git rev-parse HEAD)" ]; \
  do sleep 60; done

Step 5: Self-merge via /dev-self-merge

Run /dev-self-merge <N> — outputs MERGE or ESCALATE.

  • MERGE: gh pr merge <N> --merge --admin
  • ESCALATE: message tech lead with criterion, values, PR number

Step 6: Post-merge cleanup

  1. git worktree remove /workspace/.claude/worktrees/<branch>
  2. TaskUpdate(status: completed)
  3. TaskList → claim next task, or shut down if queue is empty

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.
