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 | $0.00036 | $0.01294 |
| Opus 5.5 | $0.00014 | $0.00518 |
| Sonnet 5.5 | $0.00007 | $0.00259 |
| Haiku 4.5 | $0.00004 | $0.00129 |
Grade A, and why
proofreader 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.
How it starts
The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Proofreader
What This Skill Does
Proofread a piece of text and return it with all spelling, grammar, punctuation, and typographical errors corrected — preserving the author's voice and intentional style choices throughout.
When To Use This Skill
- You are doing a final check before publishing an article, caption, press release, or broadcast script
- You need to verify that translated or adapted copy has not introduced language errors during revision
- You are reviewing user-generated or community-submitted content before it goes live
- You have written a draft quickly under deadline and want a clean error pass before sending to an editor
- You need to check headlines, subheadings, pull quotes, or captions that are often missed in a full-document proofread
What You Need To Provide
Required: The text to proofread.
Optional: Language variant (British English, American English, Australian English — defaults to British English if not specified); house style notes (e.g. "Oxford comma: yes", "spell out numbers under ten", "capitalise 'Government' when referring to the UK Government"); whether to flag style choices for review rather than correcting them silently.
How the Assistant Approaches This
- Reads the full text for meaning before making any corrections — understanding the author's intent, register, and deliberate style choices (sentence fragments for effect, informal voice, rule-breaking for emphasis)
- Makes a correction pass for spelling errors, grammatical mistakes, punctuation errors, and typographical issues (doubled words, missing words, transposed letters), distinguishing between genuine errors and intentional stylistic decisions
- Returns the corrected text in full, followed by a numbered change log listing every correction made — the original, the corrected version, and the reason — so the author can review and accept or reject each change individually
Output Format
Two sections:
Corrected text — the full text with all errors fixed. No annotations or markup in the text itself unless track-changes format was requested.
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.

proofreader is a skill published in the GitHub repository ur-grue/autopunk-media-skills (38 stars, last pushed 1mo ago), licensed MIT. It adds 36 tokens to every session and 1,294 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
