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 | $0.00008 | $0.00827 |
| Opus 5.5 | $0.00003 | $0.00331 |
| Sonnet 5.5 | $0.00002 | $0.00165 |
| Haiku 4.5 | $0.00001 | $0.00083 |
Grade A, and why
build 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 2mo 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build Command
Start the autonomous development cycle for: $ARGUMENTS
Your Mission
You are the Chief of Staff. Orchestrate the development team through all phases to deliver production-ready software.
Detailed Workflow
@import ../docs/workflow.md
Step 1: Initialize Workspace
mkdir -p .claude-workspace/{specs,architecture,implementation,tests,security,deployment,deliverables}
TASK_ID="task-$(date +%Y%m%d-%H%M%S)"
TIMESTAMP=$(date -u +%Y-%m-%dT%H:%M:%SZ)
cat > .claude-workspace/current-task.json << EOF
{
"task_id": "$TASK_ID",
"user_request": "$ARGUMENTS",
"status": "planning",
"created_at": "$TIMESTAMP",
"iterations": 0,
"confidence": 0
}
EOF
Step 2: Execute Phases
Use Task tool to invoke agents sequentially:
Phase 1: Planning
subagent_type: technical-pm
prompt: Create specification from the user request. Write to .claude-workspace/specs/
Phase 2: Architecture
subagent_type: senior-architect
prompt: Design architecture based on specification. Write to .claude-workspace/architecture/
Phase 3: Implementation
Implementation Standards:
- All API URLs must be configurable via environment variables
- Default to
http://localhost:3000for development - Create
.env.examplewith all required environment variables - Never hardcode URLs, ports, or secrets in source code
Run in parallel:
subagent_type: lead-backend-engineer
prompt: |
Implement backend. Write to .claude-workspace/implementation/backend/
REQUIRED: Make all API URLs configurable:
- Use environment variables (e.g., API_BASE_URL, PORT)
- Default PORT to 3000 for development
- Create .env.example documenting all env vars
- Include sample values (not real secrets)
subagent_type: frontend-engineer (if needed)
prompt: |
Implement frontend. Write to .claude-workspace/implementation/frontend/
REQUIRED: Make all API URLs configurable:
- Use environment variables (e.g., REACT_APP_API_URL, VITE_API_URL)
- Default to http://localhost:3000 for development
- Create .env.example documenting all env vars
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.
- 2mo ago First seen · 130 lines · 8 tokens per session scan A 7bbe7a992427
build is a command published in the GitHub repository MDGrey33/claude_mind (2 stars, last pushed 10mo ago), licensed MIT. It adds 8 tokens to every session and 827 once invoked, about $0.0000 per session on Opus 5.5. 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.

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.
