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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00046 | $0.01354 |
| Opus 5 | $0.00023 | $0.00677 |
| Sonnet 5 | $0.00009 | $0.00271 |
| Haiku 4.5 | $0.00005 | $0.00135 |
Grade A, and why
unattributed-claims-checker 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unattributed Claims Checker
What This Skill Does
Reads a draft article or script and flags every assertion of fact that lacks a named source, adding an inline [NEEDS SOURCE] marker so editors can see exactly where attribution is missing.
When To Use This Skill
- Before you send a draft to a senior editor or legal review
- When a piece has had multiple authors and sourcing discipline may be inconsistent
- Any time you want a quick audit of a draft before publication or broadcast
- When preparing an article that involves serious allegations, statistics, or expert claims
What You Need To Provide
Required: The full text of the draft — paste it directly into your message. Optional: A note about which claims are already known to have internal documentation (e.g., "the unemployment figures in paragraph 3 come from a government data release we have on file"). This prevents the assistant from flagging things you have already verified off-page.
How the Assistant Approaches This
- Reads the draft sentence by sentence and identifies every declarative claim — statistics, allegations, descriptions of events, characterisations of individuals or organisations, and predictions stated as fact.
- Checks whether each claim is clearly attributed to a named or sufficiently identified source (e.g., a person, institution, document, or data release) either within the sentence or in the immediately surrounding context.
- Appends
[NEEDS SOURCE]directly after any claim that lacks attribution, then returns the full annotated draft so you can see every flag in context. It also produces a numbered list of flagged claims at the end, so you can work through them without scrolling the whole piece.
Output Format
- The complete draft returned with
[NEEDS SOURCE]inserted inline after each flagged claim — no other text is altered. - A numbered summary list beneath the draft: one line per flagged claim, quoting the flagged phrase and briefly explaining what type of attribution is missing (named source, official data, on-the-record quote, etc.).
- Tone is neutral and editorial — no suggestions for how to find the source, no rewrites.
- Length of output equals the draft length plus the summary list.
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.
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.
