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.

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 | $0.00039 | $0.01440 |
| Opus 5 | $0.00019 | $0.00720 |
| Sonnet 5 | $0.00008 | $0.00288 |
| Haiku 4.5 | $0.00004 | $0.00144 |
Grade A, and why
kiro-review 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 11d 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.

kiro-review
<background_information> This skill performs task-local adversarial review. It verifies that the implementation is real, complete, bounded, aligned with approved requirements and design, and supported by mechanical verification evidence.
Boundary terminology continuity:
- discovery identifies
Boundary Candidates - design fixes
Boundary Commitments - tasks constrain execution with
_Boundary:_ - review rejects concrete
Boundary Violations</background_information>
- After an implementer reports
READY_FOR_REVIEW - After remediation for a rejected review
- Before marking a task
[x] - Before accepting a task into feature-level validation
Do not use this skill to invent missing requirements or silently reinterpret the spec.
Inputs
Provide:
- Task ID and exact task text from
tasks.md - Relevant requirement section numbers
- Relevant design section numbers
- Spec file paths (
requirements.md,design.md, optionallytasks.md) - The implementer's status report
- The task
_Boundary:_scope constraints - Validation commands discovered by the controller
- Relevant steering excerpts when applicable
- Relevant
## Implementation Notesentries when applicable
Outputs
Return one of:
APPROVEDREJECTED
Also return:
- Mechanical results
- Findings with severity
- Required remediation
- One-sentence summary
Use the language specified in spec.json.
First Action
Run git diff to inspect the actual code changes. If the diff is large or ambiguous, read the changed files directly. Do not trust the implementer report as source of truth.
Core Principle
Read the spec yourself. Read the diff yourself. Verify mechanically where possible. Reject on concrete failures rather than interpretive optimism. The main review question is not just "does it work?" but "does it stay inside the approved responsibility boundary without hiding new coupling?"
Mechanical Checks
Run these checks and use the result as primary signal.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-review is a skill published in the GitHub repository gotalab/cc-sdd (3,661 stars, last pushed 3mo ago), licensed MIT. It adds 39 tokens to every session and 1,440 once invoked, about $0.0002 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.
Other skills, from other repositories
repo-consistency-sweep
Proactive defect-class detection that handles the lower-value half of code review (per Bacchelli and Bird 2013) so human reviewers stay focused on design, intent, and knowledge transfer. Catches convention drift, ordering bugs, type-safety gaps, security and multi-tenant invariants (CWE-grounded), and operability…
pr-feedback-ingest
Turn PR feedback (Greptile, CI, bots, humans) into a structured traceable backlog aligned with TASKSTATE.md, DECISIONS.md, and IMPLEMENTATIONPLAN.md so the next execution step can be a narrow implement-approved-slice or a small planning touch without losing alignment. Corrective scope only. Use when a PR is open or…
review-hard
Review the current task changes for real correctness, safety, and maintainability risks before slice closure or PR prep, and recommend the smallest safe next step. Surfaces meaningful issues (not cosmetic feedback); not a replacement for external review systems. Returns no-op when the review would not materially…
atom-audit-fleet
Orchestrator-workers variant of atom-audit. Dispatches N Haiku workers (3-5 atoms each) to audit every atom under packages/design-system/src/atoms/ in parallel against COMPONENTGUIDELINES.md rules; merges per-worker rows into ATOMAUDIT.md table. Use when atom count >= 6 (per cost-effectiveness threshold) AND…
verify-against-rubric-fleet
Orchestrator-workers generalization of verify-against-rubric to N=many artifacts against ONE locked rubric. Dispatches N stateless Sonnet sub-agents in parallel; each receives ONE artifact + the SAME rubric + read-only tools (no TASKSTATE, no DECISIONS, no prior history); returns structured per-criterion verdict.…
