Use Cases

The rest of the docs explains what KB Labs is and how the pieces fit. This section answers the question that usually comes first:

"Okay, but what do people actually build with this?"

Two kinds of content live here:

Built with KB Labs

Real plugins maintained in the KB Labs monorepo. Each page is a short breakdown: the problem, the shape of the solution, the primitives used, and where to read the code.

• Mind — Semantic code search — hybrid BM25 + vector RAG over a codebase, with anti-hallucination verification.
• Commit Plugin — AI commit messages — generates conventional commits from git diff with a two-phase LLM escalation.
• AI Review — Automated code review — heuristic + LLM review with presets, runs in CI or locally.
• DevLink — Cross-repo dependency manager — switches link: ↔ npm across a monorepo of submodules.

These are useful as reference implementations: when you start building your own plugin, it's faster to read a working one than to read the docs.

Scenarios

Problem-first walkthroughs. Each one describes a pain point, sketches a solution built on KB Labs primitives, shows the 20 lines of code that matter, and links to the guide that covers the full setup.

• AI code review on every PR — how kb review run plugs into CI and gives actionable feedback.
• Release notes from commits — a small plugin that turns a commit range into a draft changelog.
• Team linter as a plugin — wrap your internal style guide in a plugin so everyone on the team runs the same checks.

Scenarios always end with a "Reproduce this" section — the concrete guide to follow and what to change.

How to use this section

• Browsing for ideas? Start with Built with KB Labs — seeing real plugins makes the abstract concepts click faster than any tutorial.
• Got a specific pain point? Jump to Scenarios and look for one that rhymes with yours. You'll rarely find an exact match, but the building blocks will be the same.
• Ready to build? Use a scenario as a spec, then follow the linked guide. The scenarios are intentionally light on boilerplate — the guides cover that.

If you build something interesting on KB Labs and want it listed here, open a PR against this section. A good showcase page is ~150 lines, links to the source, and tells the honest story (including what's hard).
