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 | $0.00069 | $0.00313 |
| Opus 5 | $0.00034 | $0.00156 |
| Sonnet 5 | $0.00014 | $0.00063 |
| Haiku 4.5 | $0.00007 | $0.00031 |
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
specifyCLI. Ifspecify --versionfails, install it with the speckit-cli-setup skill first.
When to use
- Before/after
specify initto 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.
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.

speckit-check is a skill published in the GitHub repository github/spec-kit-copilot (11 stars, last pushed 6d ago), licensed MIT. It adds 69 tokens to every session and 313 once invoked, about $0.0003 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 2026-08-30.
