code-change-verification

code-change-verification is a skill for Claude Code, Codex from pproenca/unifi-mcp. It costs 31 tokens per session (266 once invoked), scanned A, original, MIT.

A verification routine for code changes that runs formatting, linting, type checking, and tests. Type checking checks that code uses declared data types correctly.

In plain words
What is it for?
Verifying changes to runtime code, tests, build settings, or project configuration with the repository's automated checks.
Why use it?
It catches formatting problems, code-quality issues, type errors, and failing tests before a change is considered complete.

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

code-change-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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/run.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Code Change Verification

Overview

Ensure work is only marked complete after formatting, linting, type checking, and tests pass. Use this skill when changes affect runtime code (src/), tests, or build configuration. Skip it for docs-only or repository metadata changes unless a user asks for the full stack.

Quick start

bash .agents/skills/code-change-verification/scripts/run.sh

The script runs npm run format first, then npm run lint, npm run typecheck, and npm test in parallel with fail-fast semantics.

Manual workflow

Run from the repository root:

  1. npm run format — apply formatting fixes
  2. Then in parallel: npm run lint, npm run typecheck, npm test
  3. Stop and fix issues immediately when a command fails.
  4. Re-run the full stack after applying fixes.

When to run

  • Changes to src/ (server code, tools, types)
  • Changes to tests/
  • Changes to package.json, tsconfig.json, or CI config
Files

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.

Changes

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.
