npm package maintenance and lifecycle management for monorepo extensions. Covers health audits, dependency sync, version bumping, changelog updates, pre-publish checks, coordinated publishing, and post-publish verification. **Triggers — use this skill when:** - User asks to "publish", "release", or "version bump" extensions/packages - User says "audit packages", "check package health", "dependency sync" - User asks to "update changelogs", "prepare release", "pre-publish check" - User mentions "npm publish", "version management", "package lifecycle" - User wants to "sync dependencies" or "align versions" across packages - User asks "what needs publishing" or "which packages changed" **Covers:** Monorepo with multiple npm packages under `extensions/`. Each package has its own package.json, CHANGELOG.md, README.md, and version. Packages are scoped (e.g. `@e9n/pi-*`) and published individually.

Use this skill when optimizing token usage, reducing response verbosity, or working in high-volume development sessions. Trigger for any mention of token savings, cost optimization, concise output, compressed responses, or the --format=concise/ultra flags. Also applies during repetitive tasks, quick iterations, simple clear requests, or when the user activates token-efficient mode. This is a cross-cutting optimization that applies to all other skills.
Comprehensive error handling patterns for Python and TypeScript applications. Use this skill whenever writing try/catch blocks, creating custom error classes, implementing retry logic, designing error boundaries in React, building API error responses, or handling failures gracefully. Trigger for any code dealing with exceptions, error propagation, graceful degradation, or fault tolerance.
