hatch3r

Run a known-cause bug fix through a 3-phase test-first pipeline -- reproduce + root-cause, regression-test + fix together, then root-cause-depth review -- with full sub-agent delegation.

Diagnose a complex incident -- reproduce the symptom, rank root-cause hypotheses, design the fix path, and emit regression coverage items as a board-ready investigation

Reverse-engineer a brownfield codebase into current-state module boundaries, integration-point inventory, tech-debt register, and dependency graph via static analysis

Author a custom user-tier artifact (agent, skill, rule, command, or hook) for this project. Generates frontmatter and body skeleton, applies strict + gentle quality gates, writes to .hatch3r/overrides/{type}/, and offers to sync to all enabled adapters.

Standalone debug-and-fix workflow — add strategic debug logging, collect runtime logs from the user, perform root cause analysis, implement the fix, and clean up all debug artifacts.

System architect who designs architecture, creates ADRs, analyzes dependencies, designs APIs and database schemas, and evaluates architectural trade-offs. Use when making architectural decisions, designing new systems, or evaluating design trade-offs.

Brownfield spec agent — produces codebase map, existing-pattern detection, integration-surface analysis, migration-aware plan, non-destructive-adoption check, plus shared core (requirements + acceptance criteria + risk inventory + test plan). Use when adding to or migrating an existing codebase.

CI/CD specialist who monitors CI pipeline runs, diagnoses failures, and suggests fixes. Use when CI fails, when waiting for CI results, or when investigating flaky tests.

Context-aware rules engine that applies coding standards based on file type, location, and project conventions. Use when enforcing project rules on save or reviewing files against established patterns.

Authors user-tier custom artifacts (agents, skills, rules, commands, hooks) under .hatch3r/overrides/. Validates frontmatter schema, runs strict + gentle quality gates, and writes the artifact only when all strict gates pass.

Ongoing backlog refinement for existing board items. Re-prioritize, reclassify, re-scope, archive stale items, decompose oversized issues, merge duplicates, refresh dependencies, and remediate board health findings.

Initializes a project board (GitHub Projects V2, Azure Boards, or GitLab Issue Boards) with hatch3r's label taxonomy, status fields, and board structure. Platform detected from hatch.json.

Regenerates the living board overview dashboard from current board state. Scans all open issues, computes health metrics, and updates the meta:board-overview issue.

Shared context and procedures for all board commands. Provides platform-agnostic board config, label taxonomy, branch conventions, sync enforcement, and tooling directives. Platform-specific details are in commands/board/shared-{platform}.md.

Opt-in browser verification skill — Playwright-driven visual checks, axe-core a11y audits, screenshot regression diffs, and E2E test scaffolds. Default ON for UI-affecting agent invocations; disable globally via hatch3r config browser=off.
