speckit-specify

speckit-specify is a skill for Claude Code from rafaelandrade74/spec-forge. It costs 35 tokens per session (3,328 once invoked), scanned A, original, MIT.

A workflow for creating or updating a feature specification from a plain-language description, with the result stored in Spec-Forge, a project-specification system.

In plain words
What is it for?
Use it to define a feature's scope, requirements, and expected behavior before implementation.
Why use it?
It turns an informal feature idea into a recorded specification that later planning and task workflows can use.

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).

Spec-Forge Setup (replaces file-based Pre-Execution Checks)

This variant persists the specification in the Spec-Forge database (via its MCP server) instead of creating specs/NNN-name/spec.md. There are no git-branch or extension-hook prerequisites to check here — just resolve the project:

  1. Determine the current repository root (absolute path).
  2. Call get_or_create_project_by_repo with { repoPath: <repo root> } → note projectId.

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 feature:

    • 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. Create the feature in Spec-Forge (replaces "Create the spec feature directory"):

    • Call create_feature with { projectId, title: <human-readable title derived from the short name / description> }.
    • This returns a featureId and an auto-numbered slug (e.g. 001-user-auth) — Spec-Forge assigns the sequence number, mirroring the old NNN-<short-name> directory convention.
    • Persist the pointer to .specify/feature.json (this file is already gitignored by the Spec Kit installer — it is machine-local, per-checkout state, exactly like the original feature_directory pointer it replaces):
      {
        "spec_forge_project_id": "<projectId>",
        "spec_forge_feature_id": "<featureId>",
        "feature_slug": "<slug>",
        "feature_title": "<title>"
      }
      
      This allows downstream commands (/speckit-plan, /speckit-tasks, etc.) to locate the feature without relying on git branch name conventions or scanning specs/.

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.
