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 | $0.00034 | $0.00464 |
| Opus 5 | $0.00017 | $0.00232 |
| Sonnet 5 | $0.00007 | $0.00093 |
| Haiku 4.5 | $0.00003 | $0.00046 |
Grade A, and why
crucible-plan 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.
What it actually says
/crucible-plan
Start or continue planning an epic fantasy novel using the Crucible Structure.
Execution Instructions
IMPORTANT: When this command is invoked, you MUST:
- Invoke the
crucible-suite:crucible-plannerskill using the Skill tool - The skill will guide you through the complete planning workflow
- Follow the skill's questioning protocol with multi-choice questions
Usage
/crucible-suite:crucible-plan [your premise]- Start new planning with a premise/crucible-suite:crucible-plan continue- Resume existing planning session
What This Does
- Activates the crucible-planner skill (you must follow its instructions)
- Guides you through interactive questions for all three strands (Quest, Fire, Constellation)
- Generates 7 comprehensive planning documents:
- Crucible Thesis (philosophical core)
- Strand Maps (3 separate arc maps)
- Forge Point Blueprints (5 convergence crises)
- Dark Mirror Profile (antagonist design)
- Constellation Bible (character relationships)
- Mercy Ledger (mercy/payoff tracking)
- World Forge (world-building)
- Saves state for resumable sessions
Prerequisites
None - this is the first step in the Crucible workflow.
Example
/crucible-suite:crucible-plan A young blacksmith discovers she can forge weapons that steal the memories of those they cut. When her village is destroyed by a memory-hunting cult, she must master her forbidden gift to save the last people who remember the old ways.
What Happens Next
After planning completes, you can:
/crucible-suite:crucible-outline- Create chapter outlines from your planning documents- Review and adjust any planning document
- Add more detail to specific elements
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.

specify
Create or update the feature specification from a natural language feature description.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
