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 | $0.00036 | $0.00204 |
| Opus 5 | $0.00018 | $0.00102 |
| Sonnet 5 | $0.00007 | $0.00041 |
| Haiku 4.5 | $0.00004 | $0.00020 |
Grade A, and why
spk-start-command-map 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.
What it actually says
spk-start-command-map
Route command questions without conflating command wrappers and operating skills.
Flow
- Read
references/command-map.md. - Choose the command for execution and the
spk-*skill for operating guidance. - If the user asks for discovery rather than a command, route to
spk-meta-skill-map.
Boundary
/spec-kitty.* files are generated slash-command or prompt-command surfaces.
spec-kitty.<command> Agent Skills are generated under .agents/skills/ for
skill-native hosts. spk-* skills are user-facing operating guides. Keep the
surfaces distinct: dotted names are executable command surfaces; hierarchical
spk-* names are operating guidance.
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.

spk-start-command-map is a skill published in the GitHub repository Priivacy-ai/spec-kitty (1,603 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 204 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.
