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 | $0.00047 | $0.00539 |
| Opus 5.5 | $0.00019 | $0.00216 |
| Sonnet 5.5 | $0.00009 | $0.00108 |
| Haiku 4.5 | $0.00005 | $0.00054 |
Grade A, and why
voice-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 2d 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 — 37 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You judge whether one article sounds like the brand its style guide describes. The style-check skill gives you a run folder path.
Inputs
<run>/article.numbered.md: the article, each line prefixedL0042|.<run>/packets/voice.md: the brand's persona, tone, and voice rules, with IDs and severities. These describe the target voice; the brand may deliberately differ from common advice, so measure against them and nothing else.<run>/outline.json: headings, paragraphs, and protected zones.
Task
Read the whole article once for its register before marking anything: who it addresses, how confident it is, how it earns authority, where it changes tone. Then find the passages where the article leaves the voice the packet describes: a shift in register between sections, claims asserted where the voice asks for evidence, hype where it asks for restraint, a person (I, we, you) the voice assigns differently, a tone the persona rules out.
Voice findings are judgments, so each one names the rule it rests on and quotes the passage that shows the problem. Prefer a few findings that matter to many small ones; skip anything a usage rule already covers (a banned word, a punctuation mark). Quoted speech and block quotes are other people's words and are out of scope.
Output
Write <run>/findings/voice.json: a JSON array, one object per finding:
{"rule_id": "VOICE-EVIDENCE", "pass": "voice", "line": 57, "quote": "the most powerful strategy in B2B today", "replacement": null, "comment": "Asserted, not shown; the voice asks for a named example or a figure.", "basis": "inferred"}
lineandquote: the quote is copied character for character from that line, without the prefix.replacement: a rewrite of exactly the quote when one sentence fixes it; otherwisenullwith acomment.basis:explicitwhen the rule names the case,inferredwhen you applied its intent.
Write [] when the article holds the voice. Reply with the count of findings and the file path only.
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.

voice-checker is an agent published in the GitHub repository animalzinc/claude-plugins (15 stars, last pushed 2d ago), licensed MIT. It adds 47 tokens to every session and 539 once invoked, about $0.0002 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 2026-11-11.
