Error Boundary Creator

Add resilient error handling to React and Next.js apps: error boundaries, fallback UIs, async error handling, and error reporting.

Workflow

  1. Identify error-prone areas: async operations, third-party integrations, and route-level entry points.
  2. Wrap components in an error boundary. Use a class boundary or the react-error-boundary library. See references/class-boundaries.md.
  3. For Next.js App Router, add the relevant error.tsx, global-error.tsx, and not-found.tsx segment files. See references/nextjs-error-handling.md.
  4. Handle errors that boundaries miss (event handlers, promises) and wire up reporting. See references/async-and-reporting.md.
  5. Design fallback UIs with role="alert" and a recovery action (reset or reload).
  6. Route caught errors to a single reporting sink and test error states before shipping.

Contents

  • references/class-boundaries.md — Basic, resettable, and react-error-boundary patterns.
  • references/nextjs-error-handling.md — App Router error.tsx, global-error.tsx, not-found.tsx.
  • references/async-and-reporting.md — useAsync hook and the reportError integration module.

Best Practices

  1. Wrap at the route level for page-level isolation, and wrap third-party components separately.
  2. Provide meaningful fallbacks with a recovery option.
  3. Log every caught error to the monitoring service.
  4. Do not catch errors the code cannot meaningfully handle.
  5. Test error states in development.

agent-army

無料

Deploy a 2-layer parallel agent hierarchy for large, parallelizable work — big refactors, multi-file migrations, codebase-wide audits, bulk generation. A top-tier commander (Fable or Opus) orchestrates the swarms; the user picks a power level (Max Power / Heavy / Balanced / Economy) that sets the Opus/Sonnet/Haiku model mix per layer. Layer 1 is 3-50+ specialist agents, each with its own full context window; Layer 2 is 2+ sub-agents per member. Includes git safety, tiered sizing, a pre-deploy gate, phantom-completion checks, and multi-wave follow-up.

agent-eval-harness

無料

Use to test whether an AI agent, prompt, or skill actually works before or after it ships — build a small eval set, score runs, and catch regressions when the prompt or model changes. Trigger when the user asks whether a prompt is good, wants to compare models or versions, sees inconsistent agent output, or is about to put an agent in front of customers.

Unlike agent-army (which is for code changes), this is for DATA tasks -- processing 1000 documents, analyzing datasets, bulk content generation. Configurable swarm size, task distribution, result aggregation, progress tracking, and error recovery.
