Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00014 | $0.01912 |
| Opus 5 | $0.00007 | $0.00956 |
| Sonnet 5 | $0.00003 | $0.00382 |
| Haiku 4.5 | $0.00001 | $0.00191 |
Grade B, and why
pre-merge scanned grade B with 1 finding 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 9d 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.
Strips warnings and disclaimersmediumAnti-refusal
Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

Pre-Merge Verification
Comprehensive verification workflow before merging changes to production.
When to Use This Skill
Use this skill when:
- Creating a pull request for review
- About to merge code to main/production branch
- Need systematic verification checklist
- Want to catch issues before code review
Pre-Commit Verification
Before committing code, verify:
- Type checking passes (language-appropriate:
tsc --noEmit,mypy, etc.) - Linting passes with no errors (ESLint, Pylint, etc.)
- All existing tests pass locally
- No console.log/debug statements left in code
- Code follows project style guide
- No commented-out code blocks
Commands by Language
TypeScript/JavaScript:
# Type check
npx tsc --noEmit
# Lint
npm run lint
# or: pnpm lint
# or: npx eslint .
# Tests
npm test
# or: pnpm test
Python:
# Type check
mypy src/
# Lint
pylint src/
# or: flake8 src/
# or: ruff check src/
# Tests
pytest
# or: python -m pytest
Go:
# Format check
gofmt -l .
# Lint
golangci-lint run
# Tests
go test ./...
Pre-PR Verification
Before creating a pull request, ensure:
Required Information
- Changeset added for user-facing changes (if using changesets)
- PR description is complete with:
- Summary of changes
- Related ticket references (ENG-XXX, HEL-XXX, JIRA-XXX, etc.)
- Screenshots for UI changes (desktop, tablet, mobile)
- Breaking changes documented
- Migration guide (if breaking changes)
- New tests added for new functionality
- Documentation updated if needed (README, API docs, etc.)
Security Checklist (if API changes)
- Authentication required on protected routes
- Authorization checks implemented
- Input validation with schema (Zod, Pydantic, etc.)
- No sensitive data in logs
- No SQL injection vulnerabilities
- No XSS vulnerabilities
- Rate limiting considered
Database Changes (if schema changes)
- Migration file created
- Migration tested on local database
- Migration tested on staging database
- Down migration available (rollback plan)
- No breaking changes without migration guide
- Schema changes documented
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

pre-merge is a skill published in the GitHub repository bobmatnyc/claude-mpm-skills (75 stars, last pushed 1mo ago), licensed MIT. It adds 14 tokens to every session and 1,912 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (strips warnings and disclaimers). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
