speckit-specify

speckit-specify is a skill for Claude Code, Codex from boussadjra/vuestrata. It costs 0 tokens per session (134 once invoked), scanned A, original, MIT.

A guide for writing a detailed specification before starting significant software work. A specification records what should be built, why it matters, what is out of scope, and unusual cases to consider.

In plain words
What is it for?
Use it to create a numbered feature specification with prioritized user stories, requirements, non-goals, and edge cases. It also updates the project's specification index.
Why use it?
It turns an idea into an agreed plan before implementation begins. This reduces unclear requirements and gives later work a shared reference.

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-specify 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 10d 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.

  5. Add at most 3 [NEEDS CLARIFICATION] markers.
  6. Focus on what and why, not implementation.
  7. Update .specify/specs/README.md.

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.
