Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00010 | $0.00418 |
| Opus 5 | $0.00005 | $0.00209 |
| Sonnet 5 | $0.00002 | $0.00084 |
| Haiku 4.5 | $0.00001 | $0.00042 |
Grade A, and why
fact-check 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 3d 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
Fact Check
Verify the following claim using web search:
Process
- Search broadly - Run multiple searches with different phrasings to find diverse sources
- Evaluate sources - Prioritize academic papers, official sources, and established journalism over blogs or social media
- Cross-reference - Look for independent confirmation across at least 2-3 sources
- Report - Present findings with clear sourcing
<parallel_search_guidance> When investigating a claim, run multiple WebSearch queries in parallel with different angles (e.g., the claim itself, key terms, potential counterarguments). This builds a more complete picture efficiently. </parallel_search_guidance>
Output Format
Verdict
<verdict_definitions>
- Supported: Multiple reliable sources confirm the claim
- Partially Supported: Core claim is accurate but contains inaccuracies or missing nuance
- Disputed: Credible sources disagree; no clear consensus exists
- Unsupported: No reliable sources confirm the claim, or evidence contradicts it
- Unverifiable: Insufficient information available to assess the claim </verdict_definitions>
Evidence
Summarize key findings from sources (2-4 bullets)
Sources
List the sources consulted as markdown links
Guidelines
- State your interpretation if the claim is ambiguous before searching
- Note disagreements between sources and explain why you weighted certain sources higher
- Separate factual claims from opinions or predictions
- Ask for clarification only if the claim is too vague to search meaningfully
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.
- 3d ago First seen · 57 lines · 10 tokens per session scan A 9be6e5e92930
fact-check is a command published in the GitHub repository bengous/claude-code-plugins (4 stars, last pushed yesterday), licensed MIT. It adds 10 tokens to every session and 418 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
