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-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 2d 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

Spec Kit — check & version

Inspect the local Spec Kit environment with the Specify CLI. This skill exposes the read-only specify check and specify version commands.

Prerequisite: needs the specify CLI. If specify --version fails, install it with the speckit-cli-setup skill first.

When to use

  • Before/after specify init to confirm required tools are present.
  • To report the installed CLI version and feature capabilities.

How to invoke

# Check that all required tools are installed
specify check

# Show version and system information
specify version

# Show local CLI feature capabilities
specify version --features

# Machine-readable capabilities
specify version --features --json

Notes

  • These commands are read-only and safe to run without confirmation.
  • If the user reports a version problem, hand off to the speckit-self skill to check for and apply CLI upgrades.
Changes

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.
