mav-local-verification is a skill for Claude Code from thermiteau/maverick. It costs 51 tokens per session (1,068 once invoked), scanned A, original, Apache-2.0.

A pre-push checklist that runs code style checks, type checks, and tests before changes are sent to a shared repository.

In plain words
What is it for?
Use it to find a project's verification commands, run checks in order, and correct lint, type, or test failures before pushing.
Why use it?
It catches common problems locally, reducing failed pushes and broken builds. It also requires fixing failures before continuing.

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

mav-local-verification 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Local Verification

Run lint, typecheck, and tests locally before every push. Never push code that fails local checks.

Principles

  1. Verify locally first — never push code that fails lint, typecheck, or tests
  2. Never skip git hooks — never use --no-verify with git commands
  3. Fix before proceeding — stop at the first failure, fix it, then continue

Process

digraph verify {
    "Ready to push?" [shape=diamond];
    "Discover verification commands" [shape=box];
    "Run lint" [shape=box];
    "Lint passes?" [shape=diamond];
    "Fix lint issues" [shape=box];
    "Run typecheck" [shape=box];
    "Typecheck passes?" [shape=diamond];
    "Fix type errors" [shape=box];
    "Run tests" [shape=box];
    "Tests pass?" [shape=diamond];
    "Fix failing tests" [shape=box];
    "Push to remote" [shape=box];

    "Ready to push?" -> "Discover verification commands" [label="yes"];
    "Discover verification commands" -> "Run lint";
    "Run lint" -> "Lint passes?";
    "Lint passes?" -> "Run typecheck" [label="yes"];
    "Lint passes?" -> "Fix lint issues" [label="no"];
    "Fix lint issues" -> "Run lint";
    "Run typecheck" -> "Typecheck passes?";
    "Typecheck passes?" -> "Run tests" [label="yes"];
    "Typecheck passes?" -> "Fix type errors" [label="no"];
    "Fix type errors" -> "Run typecheck";
    "Run tests" -> "Tests pass?";
    "Tests pass?" -> "Push to remote" [label="yes"];
    "Tests pass?" -> "Fix failing tests" [label="no"];
    "Fix failing tests" -> "Run tests";
}

Discovering Verification Commands

Projects use different tooling. Discover the available commands by checking these sources in order:

  1. package.json scripts (Node.js projects):

    cat package.json | jq '.scripts | keys[]' 2>/dev/null
    

    Look for: lint, typecheck, type-check, tsc, test, test:unit, check

  2. Makefile targets:

    grep -E '^[a-zA-Z_-]+:' Makefile 2>/dev/null
    

    Look for: lint, check, test, verify, validate

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.
