Token cost

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.

Security

Grade A, and why

extract-my-voice 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 12d 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Extract My Voice

Analyze the user's actual writing across connected sources and create a voice reference file that Claude can use to match their tone and style.

Sources (check in order, use what's available)

  1. Slack: Search for messages by the user. Read across multiple channels. Minimum 50 messages for a useful analysis.
  2. Gmail: Read sent emails. Look for variety: different recipients, different purposes, different levels of formality.
  3. Notion/Docs: Read authored pages and documents. Look for longer-form writing.
  4. Provided samples: If no sources are connected, ask the user to paste 3-5 examples of their writing. Different formats if possible (email, post, doc, message).

Analysis

For each source, identify:

  • Default tone: where do they sit on formal/casual, warm/neutral, confident/tentative
  • Sentence rhythm: short/long, varied/consistent, fragments or full sentences
  • Openings and closings: how they start and end emails, messages, documents
  • Formatting preferences: bullets vs prose, headers vs flat text, emoji usage
  • Vocabulary fingerprint: words they reach for, words they consistently avoid
  • Register shifts: how does tone change by audience, channel, or format?
  • Paragraph structure: length, density, how they break up ideas

If the user writes in multiple languages, analyze each language separately. Voice often changes significantly between languages.

Output

Create context/my-voice.md with:

  1. A prose description of their voice (not a list of rules, a description that reads naturally)
  2. 3-5 short quoted examples that capture the style, pulled from actual writing
  3. A "do / don't" section with specific guidance for Claude:
    • Words and phrases to use
    • Words and phrases to avoid
    • Formatting rules (line length, list style, emoji policy)
    • Tone rules by context (emails vs posts vs docs)
  4. Separate sections per language if they write in multiple languages

After saving

Tell the user: "I'll use this file as reference whenever you ask me to write something. If I drift from your voice, tell me and I'll update the file."

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.
