Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00023 | $0.01813 |
| Opus 5 | $0.00012 | $0.00907 |
| Sonnet 5 | $0.00005 | $0.00363 |
| Haiku 4.5 | $0.00002 | $0.00181 |
Grade A, and why
crucible-review 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 — 234 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/crucible-review
Trigger a manual review of your chapters using specialized review agents.
Usage
/crucible-suite:crucible-review latest- Review most recent 2 chapters/crucible-suite:crucible-review 5-6- Review chapters 5 and 6/crucible-suite:crucible-review 1-4- Review chapters 1 through 4
Execution Instructions
IMPORTANT: When this command is invoked, you MUST:
-
ALWAYS use the AskUserQuestion tool for presenting options to the user (NOT plain text A/B/C options)
-
Detect project root - Find the Crucible project directory:
- Use Glob to search for
.crucible/directory:Glob(pattern="**/.crucible") - The project root is the PARENT of the
.crucible/directory found - Store this as
PROJECT_ROOT(absolute path) for all subsequent steps - If no
.crucible/found, inform user this must be run from within a Crucible project
- Use Glob to search for
-
Determine chapter range from the argument:
latest→ Read{PROJECT_ROOT}/.crucible/state/draft-state.jsonto find the last 2 completed chaptersX-Y→ Use chapters X through Y- Single number → Review that chapter only
-
Resolve all file paths - Build absolute paths for agents:
- Chapter files:
{PROJECT_ROOT}/draft/chapters/ch{NN}.md - Story bible:
{PROJECT_ROOT}/story-bible.json - Style profile:
{PROJECT_ROOT}/style-profile.json - Master outline:
{PROJECT_ROOT}/outline/master-outline.md - Scene breakdown:
{PROJECT_ROOT}/outline/scene-breakdown.md - World forge:
{PROJECT_ROOT}/planning/world-forge.md
- Chapter files:
-
Launch ALL 5 review agents in parallel using the Task tool with ABSOLUTE PATHS:

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-review is a command published in the GitHub repository forsonny/The-Crucible-Writing-System-For-Claude (60 stars, last pushed 8mo ago), licensed MIT. It adds 23 tokens to every session and 1,813 once invoked, about $0.0001 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.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
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
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
