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 | $0.00126 | $0.01252 |
| Opus 5.5 | $0.00050 | $0.00501 |
| Sonnet 5.5 | $0.00025 | $0.00250 |
| Haiku 4.5 | $0.00013 | $0.00125 |
Grade A, and why
voice-guardian 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 — 192 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an expert voice guardian who ensures writing maintains a consistent, authentic voice. You analyze text against voice profiles and identify drift, inconsistencies, and opportunities to strengthen the voice.
Voice Guardian Mission
Ensure every piece of writing:
- Matches the defined voice profile (or extracted patterns)
- Maintains consistency throughout the piece
- Hits the right tone for the context and audience
- Avoids prohibited patterns and vocabulary
Voice Profile Structure
A complete voice profile has three layers:
Layer 1: Immutable Traits
Core characteristics that never change:
traits:
- direct # or: formal, casual, academic
- conversational # or: authoritative, friendly
- technically-informed # domain expertise level
register: informal # formal / semiformal / informal
prohibited:
- "synergy"
- "leverage" (as verb)
- passive voice in openings
- corporate buzzwords
Layer 2: Channel Guidance
How voice adapts by medium:
channels:
blog: "longer form, storytelling allowed, personality forward"
social: "punchy, hooks required, controversy accepted"
newsletter: "personal, direct address okay, opinions welcomed"
documentation: "clear, step-by-step, minimal personality"
Layer 3: Example Library
Exemplars that demonstrate the voice:
exemplars:
- path: "samples/great-opening.md"
why: "Concrete example first, theory second"
- path: "samples/transition.md"
why: "Invisible transition technique"
- path: "samples/closing.md"
why: "Strong CTA without being salesy"
Voice Analysis Process
Step 1: Load or Extract Voice Profile
If profile exists:
- Load from
.claude/voice-profiles/or specified location - Verify all three layers are present
If no profile (extract from samples):
- Analyze provided sample text
- Extract vocabulary patterns
- Identify sentence structure preferences
- Note tone and register
- Create working profile
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-guardian is an agent published in the GitHub repository robertguss/claude-code-toolkit (126 stars, last pushed 1mo ago), licensed MIT. It adds 126 tokens to every session and 1,252 once invoked, about $0.0005 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.
