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: 3 findings, up to high
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 →

Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00015 | $0.01097 |
| Opus 5 | $0.00008 | $0.00549 |
| Sonnet 5 | $0.00003 | $0.00219 |
| Haiku 4.5 | $0.00002 | $0.00110 |
Grade A, and why
kiro-validate-gap 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 8d 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 Gap Validation
<background_information>
- Mission: Analyze the gap between requirements and existing codebase to inform implementation strategy
- Success Criteria:
- Comprehensive understanding of existing codebase patterns and components
- Clear identification of missing capabilities and integration challenges
- Multiple viable implementation approaches evaluated
- Technical research needs identified for design phase </background_information>
Execution Steps
-
Load Context:
- Read
{{KIRO_DIR}}/specs/$1/spec.jsonfor language and metadata - Read
{{KIRO_DIR}}/specs/$1/requirements.mdfor requirements - Core steering context:
product.md,tech.md,structure.md - Additional steering files only when directly relevant to the feature's domain rules, integrations, runtime prerequisites, compliance/security constraints, or existing product boundaries
- Relevant local agent skills or playbooks only when they clearly match the feature's host environment or use case and provide analysis-relevant context
- Read

Read Analysis Guidelines:
- Read
rules/gap-analysis.mdfrom this skill's directory for comprehensive analysis framework
- Read
Parallel Research
The following research areas are independent and can be executed in parallel:
- Codebase analysis: Existing implementations, architecture patterns, integration points, extension possibilities
- External dependency research: Dependency compatibility, version constraints, known integration challenges (when needed)
- Context loading: Requirements, core steering, task-relevant extra steering, relevant local agent skills/playbooks, and gap-analysis rules
If multi-agent is enabled, spawn sub-agents for each area above. Otherwise execute sequentially.
After all parallel research completes, synthesize findings for gap analysis.
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-validate-gap is a skill published in the GitHub repository gotalab/cc-sdd (3,655 stars, last pushed 3mo ago), licensed MIT. It adds 15 tokens to every session and 1,097 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.

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…
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…
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…
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.…
