Bug Fix Agent - Automated bug fixing with review loopback and auto-commit to main branch. Fixes bugs, tests them, reviews quality, and commits when quality gates pass.
You are an expert code reviewer. Your role is to independently review fix plans produced by another agent and identify issues, gaps, or risks.
Reproduce, isolate, and fix a bug (or failing build/test), then summarize root cause, fix, and verification steps. Use when the user reports a bug, regression, or failing build/test and wants a fix.

Ensures high code quality and security compliance. Use in projects with @lenne.tech/nest-server in package.json dependencies (supports monorepos with projects/*, packages/*, apps/* structure).
Execute whiteboard plans through gated phases with subagent dispatch. Require feature branch. Each phase goes through DISCOVERY -> PRE-GATE (pseudocode) -> IMPLEMENT -> POST-GATE (reviewer) -> CHECKPOINT. Produce per-phase commits, execution log, and working code with tests. Use after /code-foundations:whiteboarding to implement saved plans. Triggers on: build it, execute plan, implement the whiteboard, run the plan.
Use when generating multiple curriculum-aligned concept files in parallel (5+ concepts) - researches curriculum, creates concept list, spawns parallel generation agents, orchestrates review loop until all pass
Execute automated release workflow for Rust projects using Conventional Emoji Commits. Analyze commits since last release, determine semantic version bump (MAJOR/MINOR/PATCH), update Cargo.toml, generate changelog with git-cliff, create git tags, and publish GitHub releases. Use when the user requests to cut a release, bump version, create a release, or publish a new version. Also use when the user asks about the release process or wants to preview what the next release would be.
Build production-grade CLI tools with Bun. Reference implementation covering argument parsing patterns (--flag value, --flag=value, --flag), dual markdown/JSON output, error handling, subcommands, and testing. Use when building CLIs, designing argument parsing, implementing command structures, reviewing CLI quality, or learning Bun CLI best practices.
