speckit.specify

speckit.specify is a command for Claude Code, Cursor from caipe-io/ai-platform-engineering. It costs 13 tokens per session (3,135 once invoked), scanned A, original, Apache-2.0.

A command that turns a plain-language feature request into a concise feature specification.

In plain words
What is it for?
Use it to create or update a specification from a natural-language description and generate a short, descriptive branch name for the work.
Why use it?
It gives an informal idea a structured written definition, helping clarify what should be built before implementation begins.

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 6d 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.

User Input

$ARGUMENTS

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

Outline

The text the user typed after /speckit.specify in the triggering message is the feature description. Assume you always have it available in this conversation even if $ARGUMENTS appears literally below. Do not ask the user to repeat it unless they provided an empty command.

Given that feature description, do this:

  1. Generate a concise short name (2-4 words) for the branch:

    • Analyze the feature description and extract the most meaningful keywords
    • Create a 2-4 word short name that captures the essence of the feature
    • Use action-noun format when possible (e.g., "add-user-auth", "fix-payment-bug")
    • Preserve technical terms and acronyms (OAuth2, API, JWT, etc.)
    • Keep it concise but descriptive enough to understand the feature at a glance
    • Examples:
      • "I want to add user authentication" → "user-auth"
      • "Implement OAuth2 integration for the API" → "oauth2-api-integration"
      • "Create a dashboard for analytics" → "analytics-dashboard"
      • "Fix payment processing timeout bug" → "fix-payment-timeout"
  2. Confirm branch creation with the user BEFORE running the script. The script's default behaviour is to git checkout -b <new-branch>, which is destructive (it changes the user's checked-out branch and leaves any uncommitted spec edits on a fresh branch the user did not consent to). Some maintainers want a new branch every time; others prefer to keep spec work on the current branch and bundle it with other in-flight changes.

    • Show the user the proposed branch name (e.g. 2026-05-07-user-auth) and ask whether to create it.
    • Phrasing: "I'll create a new branch named '<proposed-branch-name>' for this spec. Reply 'no branch' (or 'stay on current branch') if you'd rather keep spec edits on '<current-branch>'."
    • Default if the user does not respond / responds ambiguously: create the branch (matches today's behaviour). But if the user has already said something like "don't create a new branch" earlier in the session — honour that without re-asking.
    • If the user declines, pass --no-branch to the script in the next step. The script will still create the spec folder under docs/docs/specs/<branch-name>/ and write spec.md; only the git checkout -b is skipped.

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.specify is a command published in the GitHub repository caipe-io/ai-platform-engineering (406 stars, last pushed yesterday), licensed Apache-2.0. It adds 13 tokens to every session and 3,135 once invoked, about $0.0001 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.
