fak: Skill for Claude Code

.agents/skills/verify/SKILL.md

verify is a skill for Claude Code, Codex from anthony-chaudhary/fak. It costs 50 tokens per session (203 once invoked), scanned A, original, Apache-2.0.

A verification workflow that ties a claim that a package or feature is finished to a successful test run for the changed code.

In plain words
What is it for?
Running the affected tests after a commit and reporting whether they passed.
Why use it?
It prevents a completion claim from being based only on how the code diff looks.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions Codex.

This is anthony-chaudhary/fak's own configuration. It tells Claude Code and Codex how to work on fak 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 fak configures →

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 →

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

verify 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.

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

Canonical project skill adapter

Load and follow ../../../.claude/skills/verify/SKILL.md. This generated discovery adapter contains no maintained workflow body.

Portability contract

  • The linked canonical SKILL.md is the single semantic workflow body for Claude, Codex, and fak-native loaders.
  • This adapter changes discovery only; it must not fork, summarize, or translate the workflow.
  • Harness-native invocation, permissions, hooks, model routing, and worker launch remain typed adapters outside the semantic body.
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.
