Agent
Enhancability quality specialist — reviews generated code for feature-flag adoption, config externalization, versioned APIs, forward-compatibility, and extension-point definition. Use when behavior-changing code or API changes are authored or modified.
Agent
Targeted fix agent that takes structured reviewer output and implements fixes for Critical and Warning findings. Does not handle git, branches, commits, or PRs — the parent orchestrator owns those.
Agent
Greenfield spec agent — produces market research, competitive analysis, user personas, tech-stack picks, PRD, acceptance criteria, risk inventory, and test plan for new projects. Use at project inception.
Agent
Session-start agent that surfaces active handoff documents from .hatch3r/handoffs/active/. Use at the beginning of a coding session to detect in-progress work for resumption.
Agent
Prepare a canonical handoff document capturing mid-work session state. Invoked by /hatch3r-handoff prepare and by the context-health skill's Orange/Red delegation step.
Agent
Focused implementation agent for a single issue. Receives issue context, delivers code changes and tests. Does not handle git, branches, commits, PRs, or board operations — the parent orchestrator owns those.
Agent
Incident-response specialist who drives a live production incident through structured triage, bounded-autonomy mitigation, stakeholder communication, and a blameless post-mortem with follow-up runbook. Use during an active outage, degradation, or security incident.
Agent
Session-start agent that surfaces relevant project learnings, recent decisions, and context from previous sessions. Use at the beginning of a coding session to get up to speed.
Agent
Code quality enforcer who fixes style, formatting, and type issues without changing logic. Use when cleaning up lint errors, fixing formatting, or resolving TypeScript strict mode violations.
Agent
Maintainability quality specialist — reviews generated code for duplication index, pattern reuse, cyclomatic complexity, expand-contract migrations, and API breaking-change discipline. Use when code is authored, refactored, or schema/API changes are introduced.
Agent
Specialist that installs a community pack into the consumer repo AFTER the trust-model gate clears. Verifies the pack's trust tier + signing method per the hatch3r trust model (https://docs.hatch3r.com/docs/reference/trust-model), dry-runs the write set, applies atomically, and rolls back on any failure. Use when an…
Agent
Performance quality specialist — reviews generated code for Core Web Vitals budgets (LCP/INP/CLS), backend p95/p99 latency, bundle size, and N+1 query elimination. Use when performance-sensitive code is authored or modified.
Agent
Product & Spec quality specialist — reviews spec artifacts (PRDs, feature specs, acceptance criteria) for testable acceptance criteria, evidence-cited discovery claims, and spec-to-implementation traceability. Use when a spec artifact is authored or revised, or when implementation diverges from its spec.
Agent
Reliability quality specialist — reviews generated services for OpenTelemetry instrumentation, SLO definition, RED+USE metrics, RFC 9457 error responses, and circuit-breaker/retry patterns. Use when service code or deploy artifacts are authored or modified.
Agent
Composable context researcher agent. Receives a research brief with mode selections and depth level, gathers context following the tooling hierarchy, returns structured findings. Does not create files or modify code — the parent orchestrator owns all artifacts.
Agent
Expert code reviewer for the project. Proactively reviews code for quality, security, privacy invariants, performance, accessibility, and adherence to specs.
Agent
Scalability quality specialist — reviews generated services for stateless handlers, back-pressure patterns, idempotency-key adoption, queue-based offloading, and connection-pool sizing. Use when service code or scaling-relevant config is authored or modified.
Agent
Security quality specialist — reviews generated code for OAuth 2.1 + OIDC + DPoP + WebAuthn server-side, supply-chain integrity (SBOM + provenance + SHA-pin + cosign), and OWASP ASI controls. Use when security-sensitive code or release-touching changes land.
Agent
Testability quality specialist — reviews generated code for per-feature test-class mandate (parser→fuzz, payment→mutation, RPC→contract), real-deal-first testing, coverage thresholds, and AI feature eval coverage. Use when test plans or test code are authored or modified.
Agent
UI quality specialist — reviews generated UI for WCAG 2.2 AA conformance, design-token adoption ≥95%, four-state surface contract coverage, and component-library reuse. Use when UI is authored or modified.
Agent
UX quality specialist — reviews generated UX flows for error-recovery clarity, first-run success, decisions-per-flow discipline, focus management, and screen-reader announcement. Use when UX flows are authored or modified.
Command
Generate or validate an OpenAPI specification from the codebase. Scans route definitions, extracts schemas, and produces a complete API spec.
Command
Answer a free-form question about the user's codebase, read-only. Triages question breadth, fans out one hatch3r-researcher per independent facet, and synthesizes an answer grounded in cited file:line evidence with a confidence rating. Never mutates files.
Command
Scaffold authentication boilerplate for a greenfield API service — OAuth 2.1 authorization-code-with-PKCE flow, OIDC ID-token validation, and hashed personal-access-token (PAT) issuance/verification. Implementer writes the code; hatch3r-security gates it against the CQ3 auth-depth floor.
