Spec Kitty is an open-source command-line tool that turns product requirements into a repository-based workflow for AI-assisted software development. It stores specifications, plans, tasks, acceptance criteria, reviews, and merge decisions in Git while giving agents isolated git worktrees for parallel implementation. The catalogue add-ons support the project's workflows for coordinating agents and governing their work.
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 | $0.00030 | $0.00476 |
| Opus 5 | $0.00015 | $0.00238 |
| Sonnet 5 | $0.00006 | $0.00095 |
| Haiku 4.5 | $0.00003 | $0.00048 |
Grade A, and why
spk-run-implement-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 3d 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.
What it actually says
spk-run-implement-review
Use this skill when a mission is in implementation/review lanes or the user wants the agent to coordinate implementers and reviewers.
Flow
- Use
spk-run-nextto identify the active WP and lane. - Dispatch implementation only from runtime-provided prompt context.
- Review each WP independently with
spk-run-review-wp. - On rejection, feed structured reviewer feedback back into the next implementation attempt.
- Continue until runtime returns terminal or a blocker.
Sub-Agent Long-Gate Contract
move-task --to for_review runs the pre-review regression gate
synchronously as part of the transition (#2570/#2493/#2555): it derives the
affected test scope for the Mission's changed files and runs it at head
before the command returns. That scoped run is a real subprocess and can
take from seconds to a few minutes depending on scope size.
- A dispatched implement/review sub-agent MUST poll the gate invocation to
completion — treat the
move-task --to for_reviewcommand as still in flight until it exits, not as a fire-and-forget hand-back. Do not assume control returns immediately, and do not kill or retry the command while it is still running. - To skip the gate for a single invocation, pass
--skip-pre-review-gate. To disable it process-wide, setSPEC_KITTY_SYNC_DISABLEorSPEC_KITTY_SYNC_MINIMAL_IMPORT(legacy-compatible gate opt-outs rather than a new third env var). Either opt-out skips the gate before it resolves a workspace or spawns the subprocess. - Absent an opt-out, the gate always enforces by default. An orchestrator
observing a sub-agent that appears to hang on a
for_reviewtransition should first check whether the gate's scoped test subprocess is still running before treating the sub-agent as stuck.
Legacy Alias
For detailed orchestration mechanics, use spec-kitty-implement-review when
available.
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.

spk-run-implement-review is a skill published in the GitHub repository Priivacy-ai/spec-kitty (1,603 stars, last pushed 3d ago), licensed MIT. It adds 30 tokens to every session and 476 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.
