Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

check 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 1mo 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

Project Health Check

Run a diagnostic scan of the current Spec Kit project to identify setup issues, missing artifacts, and configuration problems.

User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Outline

  1. Run diagnostic script: Execute {SCRIPT} from the project root and review the output.

  2. Analyze results: The script checks 6 areas:

    • Project structure — .specify/, specs/, scripts/, templates/, memory/, constitution.md
    • AI agent configuration — detects which agent folder is present, verifies commands exist
    • Feature specifications — lists features in specs/, checks for spec.md/plan.md/tasks.md
    • Scripts health — verifies all bash and PowerShell scripts are present and executable
    • Extensions health — validates extensions.yml and extension registry
    • Git status — checks if inside a git repo, shows current branch
  3. Report findings: Present the diagnostic results to the user:

    • Errors — things that are broken and need fixing
    • Warnings — things that could cause problems
    • Notes — informational items about the project state
  4. Suggest fixes: For each error or warning found, suggest the specific command or action needed to resolve it. Common fixes include:

    • Missing directories → specify init --here
    • Missing constitution → copy from templates/constitution-template.md
    • Missing feature artifacts → run /speckit.plan or /speckit.tasks
    • Non-executable scripts → chmod +x scripts/bash/*.sh
    • Empty agent commands → specify init --here --ai <agent>

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.
