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.

SkillSpector: 1 finding, up to low
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- low Excessive Agency · line 554 Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.Fix: Limit the skill's scope to its documented purpose. Remove instructions that enable the agent to perform actions outside its stated functionality.
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 | $0.00082 | $0.12002 |
| Opus 5 | $0.00041 | $0.06001 |
| Sonnet 5 | $0.00016 | $0.02400 |
| Haiku 4.5 | $0.00008 | $0.01200 |
Grade A, and why
source-verification 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 7d 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 — 591 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Source Verification
What This Skill Does
Walks through structured verification of sources, claims, images, video, and documents across five verification modes — then produces a verification-trail template the reporter can file with the story or submit to legal review.
When To Use This Skill
- A source has sent you a photo, video, or document and you need to confirm it is what they say it is before publishing
- You are fact-checking a claim that rests on visual or documentary evidence
- You want to verify the origin, date, or location of user-generated content found on social media
- An anonymous source has provided information and you need to assess credibility without revealing their identity
- Someone is presented as an expert and you need to verify their credentials, affiliations, and track record before quoting them
- You received a document (memo, contract, letter, report) and need to determine whether it is authentic
- You need a paper trail showing your newsroom's verification steps for legal or editorial review
What You Need To Provide
For visual media verification (images, video)
Required: Description of the image or video; the source's stated provenance (who sent it, when, what they say it shows) Optional: The file itself or a URL where it was found; any metadata already extracted; the publication deadline; whether the material will be used in a legal or regulatory context
For document verification
Required: Description of the document (type, date, issuing body); the source's stated provenance; why you believe it may need verification (unsolicited, unexpected content, anonymous origin) Optional: The document file; known reference documents from the same issuing body; any prior correspondence with the source
For anonymous source verification
Required: The claim the source is making; what the source says about their access to the information (position, proximity, how they obtained it); any corroborating material they have provided Optional: The channel through which the source made contact; any pattern of prior contact; whether the source has asked for specific protections (legal, physical safety)
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.

source-verification is a skill published in the GitHub repository ur-grue/autopunk-media-skills (30 stars, last pushed 10d ago), licensed MIT. It adds 82 tokens to every session and 12,002 once invoked, about $0.0004 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 2026-09-04.
