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.
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.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00012 | $0.02217 |
| Opus 5 | $0.00006 | $0.01108 |
| Sonnet 5 | $0.00002 | $0.00443 |
| Haiku 4.5 | $0.00001 | $0.00222 |
Grade A, and why
kiro-spec-tasks 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.

Implementation Tasks Generator
<background_information>
- Success Criteria:
- All requirements mapped to specific tasks
- Tasks properly sized (1-3 hours each)
- Clear task progression with proper hierarchy
- Natural language descriptions focused on capabilities
- A lightweight task-plan sanity review confirms the task graph is executable before
tasks.mdis written </background_information>
Step 1: Load Context
Read all necessary context:
{{KIRO_DIR}}/specs/$1/spec.json,requirements.md,design.md{{KIRO_DIR}}/specs/$1/tasks.md(if exists, for merge mode)- Core steering context:
product.md,tech.md,structure.md - Additional steering files only when directly relevant to requirements coverage, design boundaries, runtime prerequisites, or team conventions that affect task executability
Validate approvals:
- If
-yflag provided: Auto-approve requirements and design in spec.json. Tasks approval is also handled automatically in Step 4. - Otherwise: Verify both approved (stop if not, see Safety & Fallback)
- Determine sequential mode based on presence of
--sequential
Step 2: Generate Implementation Tasks
Load generation rules and template:
- Read
rules/tasks-generation.mdfrom this skill's directory for principles - If
sequentialis false: Readrules/tasks-parallel-analysis.mdfrom this skill's directory for parallel judgement criteria - Read
{{KIRO_DIR}}/settings/templates/specs/tasks.mdfor format (supports(P)markers)
Parallel Research
The following research areas are independent and can be executed in parallel:
- Context loading: Spec documents (requirements.md, design.md), steering files
- Rules loading: tasks-generation.md, tasks-parallel-analysis.md, tasks template
If multi-agent is enabled, spawn sub-agents for each area above. Otherwise execute sequentially.
After all parallel research completes, synthesize findings before generating tasks.
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.

kiro-spec-tasks is a skill published in the GitHub repository gotalab/cc-sdd (3,659 stars, last pushed 3mo ago), licensed MIT. It adds 12 tokens to every session and 2,217 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.
