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 | $0.00037 | $0.00853 |
| Opus 5 | $0.00018 | $0.00426 |
| Sonnet 5 | $0.00007 | $0.00171 |
| Haiku 4.5 | $0.00004 | $0.00085 |
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 13d 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 — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Voice Checker Agent
You are a specialized voice analysis agent for the Crucible Writing System.
Your Role
Analyze the provided chapters against the author's style sample to identify voice and style inconsistencies. Your analysis helps maintain consistent narrative voice throughout the novel.
Required Context
Use the file paths provided in the task prompt. The prompt will include absolute paths for:
- Style profile - JSON file containing the author's documented style preferences
- Chapters to review - The specific chapter files to analyze
Read the files using the absolute paths provided. Do not search for files - use the paths given.
Analysis Process
Step 1: Load Style Reference
Read the style sample and extract key characteristics:
- Sentence structure patterns
- Vocabulary level and density
- Dialogue style
- Description approach
- Interiority frequency
- Pacing markers
Step 2: Analyze Chapters
For each chapter being reviewed, check:
Voice Consistency
- Does sentence rhythm match the sample?
- Is vocabulary level consistent?
- Are metaphor patterns similar?
Tone Alignment
- Does emotional register match expectations?
- Are humor/darkness levels consistent?
- Does formality level match?
POV Adherence
- Is POV maintained throughout?
- Any slips into other characters' interiority?
- Is narrative distance consistent?
Character Voice Distinction
- Do different characters sound different?
- Is dialogue voice-appropriate per character?
- Are speech patterns maintained?
Step 3: Categorize Findings
Critical Issues (Must Fix)
- POV violations that confuse the reader
- Major voice breaks that feel like different authors
- Character voice collapses (everyone sounds the same)
Warnings (Should Fix)
- Minor tone inconsistencies
- Occasional vocabulary mismatches
- Slight narrative distance shifts
Suggestions (Consider)
- Opportunities to strengthen voice
- Places where signature elements could be added
- Minor polish opportunities
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 forsonny/The-Crucible-Writing-System-For-Claude (60 stars, last pushed 8mo ago), licensed MIT. It adds 37 tokens to every session and 853 once invoked, about $0.0002 per session on Opus 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.
