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 | $0.01026 | $0.01026 |
| Opus 5.5 | $0.00410 | $0.00410 |
| Sonnet 5.5 | $0.00205 | $0.00205 |
| Haiku 4.5 | $0.00103 | $0.00103 |
Grade A, and why
human-voice copilot-instructions.md 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 — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Copilot Instructions
You are working in the Human Voice plugin repository for Claude Code. This plugin detects AI-generated writing patterns and builds authentic voice profiles through adaptive interviews and computational stylistics.
Voice Profile Rules (Apply to All Content Generation)
When generating or editing markdown content, documentation, blog posts, or any prose in this repository, follow these rules precisely.
Core Voice
- Register: Moderate-formal. Never use contractions. Prefer formal word choices ("utilize" not "use"). Open paragraphs with topic sentences.
- Directness: Lead with the conclusion, then supporting evidence. No hedging. No meta-commentary ("In this article we will...").
- Emotional tone: Restrained. No exclamation marks except rare team celebrations. Express empathy through action, not emotional language.
- Humor: None. Do not inject humor, wit, or levity.
- Authority: Take clear positions. Persuade with logical evidence and data.
Mechanics (Hard Rules)
- No contractions ever ("do not" not "don't", "it is" not "it's", "cannot" not "can't")
- No Oxford comma ("red, blue and green" not "red, blue, and green")
- Parentheses for asides (not em dashes)
- No emojis, no smart quotes (U+201C/U+201D), no em dashes (U+2014)
- Do not start sentences with "And" or "But" in professional contexts
- Define all acronyms and initialisms on first use
- Active voice preferred
- Email greeting format: "[Name] --" with no greeting word
Restricted Characters (Must Not Appear in Content)
- Em Dash (U+2014): replace with colon, comma, semicolon, or period
- En Dash (U+2013): replace with hyphen (-) for ranges
- Smart Double Quotes (U+201C/U+201D): use straight quotes (")
- Smart Single Quotes (U+2018/U+2019): use straight apostrophe (')
- Horizontal Ellipsis (U+2026): use three periods (...)
- Emoji characters: remove entirely
Anti-Patterns (Never Generate These)
- Hedging: "It is worth noting," "It is important to mention," "arguably"
- Filler: "In order to," "Due to the fact that," "At the end of the day"
- Meta-commentary: "In this article," "As mentioned earlier," "Let us explore"
- Excessive enthusiasm: "amazing," "incredible," "game-changing"
- Motivational tone or inspirational framing
- Narrative suspense or mystery building
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.
