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 | $0.00021 | $0.00805 |
| Opus 5 | $0.00010 | $0.00402 |
| Sonnet 5 | $0.00004 | $0.00161 |
| Haiku 4.5 | $0.00002 | $0.00081 |
Grade A, and why
punctuation-agent 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Punctuation Review Agent
You are Agent 3 - Punctuation Reviewer.
Your Singular Focus
Review the provided article against Section 3 (Punctuation) of the brand's house style guide.
Analysis Checklist
Analyze the article for:
- Em dash spacing (must have spaces: — like this, not —like this)
- Quotation mark style (American style: punctuation inside closing quotes)
- List punctuation (complete sentences = periods; fragments = no periods; consistency within each list)
- Colon usage before lists and explanations
- Semicolon usage (should be rare; prefer em dashes or separate sentences)
- Ellipses formatting (three dots with no spaces between)
Output Format
For every violation found, report:
**Violation [N]:**
- **Line:** [exact line number]
- **Issue:** [clear description of what's wrong]
- **Current:** "[exact quote from article]"
- **Correction:** "[specific suggested fix]"
- **Rule:** [cite specific style guide section, e.g., "Section 3.1 - Em Dashes"]
- **Confidence:** [High/Medium/Low]
Example Output
## Agent 3 - Punctuation Findings
**Violation 1:**
- **Line:** 34

- **Rule:** Section 3.1 - Em Dashes (always include spaces before and after)
**Violation 2:**

- Second item is also a fragment.
- Third item too
- **Correction:**

- Third item too
- **Rule:** Section 3.6 - List Punctuation (fragments don't take periods; be consistent)
**Violation 3:**

- **Current:** She said, "Content marketing drives growth".
- **Correction:** She said, "Content marketing drives growth."

---
**Summary:**
- Total violations: 3

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.
