About the project

cc-sdd is a spec-driven development workflow for coding agents: it turns approved software specifications into requirements, designs, task plans, and extended autonomous implementation. Developers use it across several AI coding agents, with independent review and task-level continuation for long-running work. The catalogue entries provide commands, skills, agents, and instructions for using this workflow.

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

kiro-spec-init 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Spec Initialization

Execution Steps

  1. Check for Brief: If {{KIRO_DIR}}/specs/{feature-name}/brief.md exists (created by /kiro-discovery), read it. The brief contains problem, approach, scope, and constraints from the discovery session. Use this to pre-fill the project description and skip clarification questions that the brief already answers.
  2. Clarify Intent: The Project Description in requirements.md must contain three elements: (a) who has the problem, (b) current situation, (c) what should change. If a brief.md exists and covers these, skip to step 3. Otherwise, ask the user to clarify before proceeding. Ask as many questions as needed; do not fill in gaps with your own assumptions.
  3. Check Uniqueness: Verify {{KIRO_DIR}}/specs/ for naming conflicts. If the directory already exists with only brief.md (no spec.json), use that directory (discovery created it).
  4. Create Directory: {{KIRO_DIR}}/specs/[feature-name]/ (skip if already exists from discovery)
  5. Initialize Files Using Templates:
    • Read {{KIRO_DIR}}/settings/templates/specs/init.json
    • Read {{KIRO_DIR}}/settings/templates/specs/requirements-init.md
    • Replace placeholders:
      • {{FEATURE_NAME}} → generated feature name
      • {{TIMESTAMP}} → current ISO 8601 timestamp
      • {{PROJECT_DESCRIPTION}} → from brief.md if available, otherwise $ARGUMENTS
      • {{LANG_CODE}} → language code (detect from user's input language, default to en)
    • Write spec.json and requirements.md to spec directory

Important Constraints

  • Do NOT generate requirements, design, or tasks. This skill only creates spec.json and requirements.md.

Output Description

Provide output in the language specified in spec.json with the following structure:

  1. Generated Feature Name: feature-name format with 1-2 sentence rationale
  2. Project Summary: Brief summary (1 sentence)
  3. Created Files: Bullet list with full paths
  4. Next Step: Command block showing /kiro-spec-requirements <feature-name>

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.
