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

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.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/compile_edited.py, scripts/diff_report.py, scripts/init_edit.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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:

  1. Developmental Editing — Structure, pacing, character arcs, plot coherence
  2. Line Editing — Scene-level prose improvement, voice consistency
  3. Copy Editing — Grammar, consistency, style guide adherence
  4. Final Polish — Micro-level refinement, word choice, rhythm

Before Starting

Read these references based on editing phase:

  • references/developmental-checklist.md — Structure and story issues
  • references/line-editing-guide.md — Prose improvement techniques
  • references/copy-editing-standards.md — Grammar and style rules
  • references/polish-techniques.md — Final refinement methods

Questioning Rules

  1. ALWAYS use AskUserQuestion tool for all user questions (provides interactive UI)
  2. Max 4 options per question (tool limit) + "Other" is automatic
  3. Max 4 questions per AskUserQuestion call
  4. Reference specific issues by location (chapter, scene, paragraph)
  5. Batch similar decisions when possible

CRITICAL: Use the AskUserQuestion tool, NOT plain text A/B/C options.

Required Inputs

Before editing can begin, gather:

  1. Draft Chapter(s) (required) — The crucible-writer output to edit
  2. Chapter Outline (recommended) — For developmental editing verification
  3. Style Profile (recommended) — For voice consistency checking
  4. Story Bible (as needed) — For continuity verification
  5. 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 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.
