Write PR descriptions that fellow devs actually want to read.
foo parameter to bar function")Title: Short, specific, interesting. Convey what changed from a user/dev perspective, not which files were touched. Use imperative mood. Under 70 chars.
Body: Write in paragraphs, not bullet lists. Structure:
Opening paragraph — What this PR does and why, in 2-3 sentences. Bold the key behavioral change. If there's a motivating problem, state it directly.
Details paragraph(s) — Only if the approach is non-obvious or has trade-offs worth calling out. Use italics for subtle points. Keep it high-level; reviewers can read the diff for implementation details.
Anything notable — Breaking changes, migration steps, or things reviewers should pay attention to. Only if applicable. Use > blockquote for callouts.
Closes #123, See #456)If the repo is a Nix flake and the PR branch contains a buildable output (package, NixOS config, etc.), include a "Try it locally" section at the end of the body. Use the GitHub owner/repo and branch name to construct the command:
### Try it locally
`nix run github:<owner>/<repo>/<branch>`
Adjust the command as needed — nix build for non-runnable outputs, add #<output> if the default package isn't the relevant one. Omit this section entirely if the change isn't meaningfully testable via nix run/build (e.g., CI-only changes, documentation, non-Nix repos).
When the user pushes further changes to an already-PR'd branch:
gh pr editTitle: Update NixOS configuration and add new service
## Summary
- Added `kolu` service configuration
- Updated `flake.lock`
- Modified port from 8080 to 8090
- Added health check endpoint
- Updated README
## Testing
- Tested locally
Title: Add kolu service with health monitoring
**Kolu now runs as a standalone NixOS service** with its own systemd
unit and a dedicated health-check endpoint. Previously it was bolted
onto the main app process, which made restarts disruptive.
The service binds to port 8090 to avoid clashing with the dev server.
*Health checks hit `/healthz` every 30s — systemd restarts the
service on three consecutive failures.*
Review code for quality, simplicity, and common mistakes before declaring work complete.
Evaluate code (especially LLM-generated) for structural simplicity using Rich Hickey's "Simple Made Easy" framework. Use this skill whenever reviewing a PR, diff, or code snippet for accidental complexity — particularly when the code was generated by an AI coding assistant and line-by-line review isn't feasible. Also use when the user asks about complecting, simplicity vs. easiness, structural coupling, or wants architecture fitness functions for a codebase. Trigger on phrases like "is this simple", "does this complect", "review for complexity", "structural analysis", "fitness function", or any reference to Hickey, Simple Made Easy, or grey-box review.
