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

speckit.checklist 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

/speckit.checklist — requirements-quality checklist (before-plan)

/speckit.checklist is a lifecycle-adjacent Spec Kit command that belongs before planning. Use it to review the specification for requirement quality, catching vague, incomplete, inconsistent, or missing requirements before /speckit.plan runs.

  • Lifecycle placement: before-plan.
  • Purpose: improve requirement clarity, completeness, consistency, and edge-case coverage.
  • Proportional use: recommended for substantive feature work; optional for low-risk, lightweight slices.
  • It does not replace planning and is not mandatory for every tiny slice.

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.
