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 | $0.00088 | $0.03087 |
| Opus 5 | $0.00044 | $0.01543 |
| Sonnet 5 | $0.00018 | $0.00617 |
| Haiku 4.5 | $0.00009 | $0.00309 |
Grade A, and why
crucible-editor 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 — 520 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Crucible Editor
Revision and editing assistant for Crucible-drafted novels, handling developmental editing through final polish.
Overview
The Crucible Editor provides structured editing support at four levels:
- Developmental Editing — Structure, pacing, character arcs, plot coherence
- Line Editing — Scene-level prose improvement, voice consistency
- Copy Editing — Grammar, consistency, style guide adherence
- Final Polish — Micro-level refinement, word choice, rhythm
Before Starting
Read these references based on editing phase:
references/developmental-checklist.md— Structure and story issuesreferences/line-editing-guide.md— Prose improvement techniquesreferences/copy-editing-standards.md— Grammar and style rulesreferences/polish-techniques.md— Final refinement methods
Questioning Rules
- ALWAYS use AskUserQuestion tool for all user questions (provides interactive UI)
- Max 4 options per question (tool limit) + "Other" is automatic
- Max 4 questions per AskUserQuestion call
- Reference specific issues by location (chapter, scene, paragraph)
- Batch similar decisions when possible
CRITICAL: Use the AskUserQuestion tool, NOT plain text A/B/C options.
Required Inputs
Before editing can begin, gather:
- Draft Chapter(s) (required) — The crucible-writer output to edit
- Chapter Outline (recommended) — For developmental editing verification
- Style Profile (recommended) — For voice consistency checking
- Story Bible (as needed) — For continuity verification
- Review Reports (if available) — From bi-chapter review agents
Workflow
Phase 1: ASSESSMENT → Load draft, identify editing level needed
Phase 2: DEVELOPMENTAL → Structure and story issues (if needed)
Phase 3: LINE EDITING → Prose improvement scene-by-scene
Phase 4: COPY EDITING → Grammar and consistency pass
Phase 5: POLISH → Final refinement
Phase 6: COMPILE → Generate edited manuscript
What ships with it

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.

crucible-editor is a skill published in the GitHub repository forsonny/The-Crucible-Writing-System-For-Claude (60 stars, last pushed 8mo ago), licensed MIT. It adds 88 tokens to every session and 3,087 once invoked, about $0.0004 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.
