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 | $0.00000 | $0.00504 |
| Opus 5 | $0.00000 | $0.00252 |
| Sonnet 5 | $0.00000 | $0.00101 |
| Haiku 4.5 | $0.00000 | $0.00050 |
Grade A, and why
fact-gate 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.
How it starts
The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Fact Gate
Verify every factual, legal, or financial claim against a dated primary source before anything ships. This is a blocking discipline: a draft does not pass until each checkable claim is signed off.
When to use
Any deliverable that cites laws, official figures, statistics, regulations, rates, or deadlines — or whenever someone asks "is this accurate?" / "check this against sources."
The protocol
-
Extract the checkable claims. Walk the draft and pull out every assertion a reader could dispute: numbers, dates, rates, thresholds, named rules, jurisdictions. Restate each as a single, testable sentence.
-
Class each claim. Tag the kind of claim, because each kind has a typical failure mode:
- Rate / amount — often stale; verify the year it applies to.
- Threshold / phase-out limit — easy to off-by-one; confirm the exact band.
- Deadline — confirm the current cycle, not last year's.
- Jurisdiction / forum — confirm the level (federal vs state, court vs agency); loose phrasing from a single outlet is a classic trap.
-
Match each claim to a dated primary source. Prefer the authoritative issuer (the statute, the official table, the regulator's own page) over a secondary summary. Record the source and its date next to the claim.
-
Block on the unverifiable. If a claim cannot be tied to a primary source, it does not ship as fact. Either soften it to attributed opinion ("according to X…"), or cut it. Never assert a number you could not source.
-
Re-read for the silent claim-classes. Court forum, effective dates, "up to" limits, and percentages are the ones a casual pass skips. Sweep for them explicitly.
Output
A claims ledger: each claim, its class, its dated source, and a status of SIGNED / SOFTENED / CUT. The draft passes only when no claim is left unsigned. If anything is post-dated beyond your knowledge or unsourced, say so plainly rather than guessing.
Honesty rule
"I could not verify this" is a valid, valuable result. A fact gate that waves everything through is not a gate.
What ships with it
3 files 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.

fact-gate is a skill published in the GitHub repository chadcorp/warden (0 stars, last pushed 2mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 504 tokens. 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 2026-08-31.
