Audit code for correctness and rigor — logic errors, silent error swallowing, wishful thinking, and unjustified fallbacks.

  • You want a focused correctness audit separate from the full code-police pass
  • SKILL.md covers 0. Determine Scope, What to flag, Workflow and Principles, plus 1 more section
  • Calls git
  • Tasks that involve Fact-checking and source verification

What it does

Fact Check is an agent skill from srid/emanote. Audit code for correctness and rigor — logic errors, silent error swallowing, wishful thinking, and unjustified fallbacks. This is not a style review; it's a logic review. Use when you want a focused correctness audit separate from the full code-police pass.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Research & Science, covering Fact-checking and source verification. The repository describes itself as: Emanate a structured view of your plain-text notes.

When your agent uses it

  • You want a focused correctness audit separate from the full code-police pass
  • Tasks that involve Fact-checking and source verification

Example prompts

  • “/fact-check”

What it can do on your machine

Read from SKILL.md and the folder at commit 9d01037. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Fact Check loads about 1.1k tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 635 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 635 words (~1,141 tokens).

“Audit code for correctness and rigor. This is not a style review — it's a logic review. Find places where the code lies to itself.”
