/plugin install vkit@vkit
| Type | Name | What it does |
|---|---|---|
| Skill | oss-contribution |
Open-source contribution workflow: pick an issue, avoid duplicate work, prove the fix (fails before, passes after), publish, triage |
| Skill | interview-pair |
Pair-programming interview habits (the 3 facts before the first edit, codebase orientation) and mock interview mode |
| Skill | architecture |
Architecture docs with C4 Mermaid diagrams, step-by-step system design, ADRs, system-design interview practice |
| Skill | requirement-tdd |
Requirement-first TDD: owner-decided numbered rules, one acceptance test per rule (red first), minimum code, and how to stop endless review loops |
| Skill | skill-scout |
Finds existing skills (local, skills.sh, GitHub), vets them for risks, installs only after confirmation |
| Agent | pr-test-analyzer |
Reviews whether a PR's tests actually cover the changed behavior |
| Agent | silent-failure-hunter |
Finds swallowed errors, dangerous fallbacks, lost error propagation |
