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 | $0.00115 | $0.03082 |
| Opus 5 | $0.00057 | $0.01541 |
| Sonnet 5 | $0.00023 | $0.00616 |
| Haiku 4.5 | $0.00012 | $0.00308 |
Grade A, and why
crucible-planner 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.

The opening of the file, as written. The whole thing — 417 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Crucible Planner
Interactive planning system for epic fantasy novels using the Crucible Structure.
Overview
Starting from a simple premise, guide users through multi-choice questions to build seven interconnected planning document categories (14 files total):
- Crucible Thesis — philosophical core
- Strand Maps — Quest, Fire, Constellation (3 separate maps)
- Forge Point Blueprints — five convergence crises
- Dark Mirror Profile — antagonist design
- Constellation Bible — character relationships
- Mercy Ledger — mercy/payoff tracking
- World Forge — world-building
Before Starting
Always read these references:
references/crucible-structure.md(the 36-beat structure)references/question-sequences.md(complete question flows)
Workflow
Phase 1: INTAKE → Accept premise, initialize state, confirm scope
Phase 2: QUESTIONING → 9 document cycles with multi-choice questions
Phase 3: COMPILATION → Generate documents, present package
Phase 1: Intake
Accept Premise
Extract from user input:
- Core concept (1-2 sentences)
- Protagonist sketch
- Central conflict hint
If premise too vague, use AskUserQuestion:
{
"questions": [
{
"header": "Protagonist",
"question": "Who is your protagonist?",
"options": [
{"label": "Reluctant chosen one", "description": "A chosen one who doesn't want the role"},
{"label": "Ordinary hero", "description": "An ordinary person thrust into extraordinary circumstances"},
{"label": "Fallen power", "description": "A powerful figure who's lost everything"},
{"label": "Seeking redemption", "description": "A morally gray character seeking redemption"}
],
"multiSelect": false
}
]
}
Initialize State
python scripts/init_project.py "./crucible-project" "Title" "Premise"
Confirm Scope
Use AskUserQuestion to confirm scope:
{
"questions": [
{
"header": "Novel Length",
"question": "What is your target novel length?",
"options": [
{"label": "Standard", "description": "100-150K words, ~20-25 chapters"},
{"label": "Epic", "description": "150-250K words, ~25-35 chapters"},
{"label": "Extended/Series", "description": "250K+ words or multi-book series, 35+ chapters"}
],
"multiSelect": false
},
{
"header": "Complexity",
"question": "What is your narrative complexity?",
"options": [
{"label": "Single POV", "description": "Single protagonist focus"},
{"label": "Dual POV", "description": "Two protagonists sharing the story"},
{"label": "Ensemble", "description": "Multiple POVs (3-5 characters)"}
],
"multiSelect": false
}
]
}

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-planner 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 115 tokens to every session and 3,082 once invoked, about $0.0006 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.
