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 | $0.00027 | $0.02418 |
| Opus 5 | $0.00014 | $0.01209 |
| Sonnet 5 | $0.00005 | $0.00484 |
| Haiku 4.5 | $0.00003 | $0.00242 |
Grade A, and why
sw-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 5d 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 — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Specwright Plan
Goal
Turn the approved design into implementation-ready specs with testable acceptance
criteria. Decompose into ordered work units if large. Operates autonomously,
applying protocols/decision.md for all decisions. Gate handoff at the end.
Inputs
{worktreeStateRoot}/session.json-- selected work for this worktree{repoStateRoot}/work/{selectedWork.id}/workflow.json-- selected work state{workArtifactsRoot}/{selectedWork.id}/design.md-- approved solution design{workArtifactsRoot}/{selectedWork.id}/context.md-- research findings from sw-design{workArtifactsRoot}/{selectedWork.id}/decisions.md-- design-phase decisions- Conditional design artifacts:
data-model.md,contracts.md,testing-strategy.md,infra.md,migrations.md {projectArtifactsRoot}/CONSTITUTION.md-- practices to follow{projectArtifactsRoot}/config.json-- project configuration
Outputs
Single-unit work: spec.md + plan.md in {workArtifactsRoot}/{selectedWork.id}/ (flat layout).
Multi-unit work: For each unit in {workArtifactsRoot}/{selectedWork.id}/units/{unit-id}/:
spec.md + plan.md + context.md. workUnits array in workflow.json.
Also: integration-criteria.md in the design-level directory ({workArtifactsRoot}/{selectedWork.id}/).
Also: {repoStateRoot}/work/{selectedWork.id}/stage-report.md for the planning handoff.
Also: decisions.md updated with planning-phase autonomous decisions.
Constraints
Stage boundary (LOW freedom):
Follow protocols/stage-boundary.md. Produce specs and plans. NEVER implement, branch,
test, or commit. After gate handoff, STOP.
Pre-condition check (LOW freedom):
Resolve the selected work from the current worktree session. Check that
selectedWork.status is designing or planning and design.md exists.
sw-plan operates on the current worktree's attached work only.
If another live top-level worktree owns that selected work, STOP and require
explicit /sw-adopt guidance before mutating specs or plans here. Matching the
recorded branch alone must not imply takeover.
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.

sw-plan is a skill published in the GitHub repository Obsidian-Owl/specwright (9 stars, last pushed 4mo ago), licensed MIT. It adds 27 tokens to every session and 2,418 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 2026-08-31.

new-skill
Scaffold a new brooks-lint analysis skill so it passes npm run validate and npm run evals on the first try — generates skills/{name}/SKILL.md (with the mandatory "Do NOT trigger for:" clause and a Process section citing guide step ranges) plus skills/{name}/{name}-guide.md (sequentially numbered steps), then appends…
llm-friendly-context
Clarifies inputs, outputs, success criteria, decisions, and unresolved conditions so downstream consumers can execute without guessing. Use when writing or revising LLM-facing prompts, handoffs, planning artifacts, reviews, reports, or generated instructions.
cco-task
Organize work by task, track tokens/cost per task, and keep a small patchable execution state that is re-injected after /compact (SKILL.state-style) — start a task, patch its state, list tasks, or mark the active one done. Pairs with /cco-pack to load minimal context per task.
cco-templates
Manage context templates for common task types.
discuss
Use when exploring a feature idea before committing, or revisiting a parked one. Triggers — "/engineer.discuss", "/engineer.discuss ", "I have an idea about", "should we build", "let's think about".
