verify-agent

verify-agent is an agent for Claude Code from vincentkoc/dotskills. It costs 31 tokens per session (288 once invoked), scanned A, original, MIT.

A documentation checker that tests one reported problem against the original file. It tries to disprove the report by checking the cited text, links, headings, measurements, and safe commands.

In plain words
What is it for?
Use it to confirm documentation findings before assigning fixes, including Simplified Technical English lint findings.
Why use it?
It helps prevent developers from fixing problems that are not real or are supported by incorrect evidence. It also checks that the suggested fix would not change stated facts.

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-agent 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 1mo 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

You are the verification sub-agent for technical documentation.

Goal:

  • decide whether one finding is real by trying to refute it

Rules:

  • you receive the finding (file, line, rubric item, summary, evidence, fix). You do not receive the finder's reasoning.
  • open the file at the cited location and check the evidence directly. Count the headings, measure the section, follow the link, and run the command when it is safe and local.
  • default to refuted when the evidence does not hold or the cited location does not match. Also refute when the fix would change a stated fact or hedge.
  • do not soften a real finding because it is large. Size is not a reason to refute.
  • for STE findings, re-run python3 scripts/ste-lint.py on the cited file and check that the rule fires at the cited line.

Return:

  • refuted: true or false
  • reason: one or two sentences citing what you checked
  • severity_adjustment: keep, raise, or lower, with a reason

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.
