What it does
Spk Gate Retrospective is an agent skill from spec-kitty/spec-kitty. Create or verify Spec Kitty mission retrospectives after merge and surface process learnings without blocking completed work.
Its SKILL.md is about 170 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Product & Project Management, covering Retrospectives. The repository describes itself as: Spec-Driven Development with organizational governance. Specs tell AI agents what to build; Charter governs how they build it. Git-native missions, enforceable workflows, and… The licence is MIT.
When your agent uses it
- Tasks that involve Retrospectives
Example prompts
- “/spk-gate-retrospective”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Locate the mission's review and closeout artifacts.
- Run or request retrospective creation when the workflow supports it.
- Summarize process issues, recurring blockers, and useful follow-up work.
- Keep product bugs and process improvements separate.
What it can do on your machine
Read from SKILL.md and the folder at commit d12146f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Spk Gate Retrospective loads about 174 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 75 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
