Use when searching or replacing code patterns - use ast-grep instead of text search for semantic accuracy

Navigate code with IDE features and run proactive LSP diagnostics on files/folders/batches. Use as PRIMARY for code intelligence and type/error checks.

Use when writing a new pi-lens ast-grep rule YAML file — covers schema, drop path, gotchas, and NAPI runner constraints

Use when writing a new pi-lens tree-sitter query rule YAML file — covers schema, S-expression syntax, capture names, predicates, and gotchas

Anthropic Claude Pro/Max OAuth compatibility workflow for this repo. Use when debugging Anthropic OAuth failures, misleading extra-usage errors, Pi request shaping, prompt fingerprinting, or deciding between hook-based fixes and deeper provider overrides.

Aggressive design-polish skill for making websites feel authored, editorial, image-led, and typographically intentional. Use when a page looks too generic, safe, same-font, SaaS-like, cluttered, or visually under-authored.

TypeScript conventions, code design principles (SOLID, self-documenting code, file organization), structural design heuristics (dependency width, LoD, output arguments), pnpm rules, ES2024 target, and Pi SDK patterns. Load during implementation, refactoring, or code review.

Pi skill frontmatter reference and template. Use when creating or reviewing project skills so they conform to Pi's Agent Skills frontmatter rules, naming constraints, and description requirements.

Google Calendar CLI for listing calendars, viewing/creating/updating events, and checking availability.

Heuristics and process for discovering structural improvements in this package. Load when planning a new improvement round — contains the smell taxonomy, analysis workflow, and prioritization framework. Tool-agnostic; this repo has no fallow, so analysis relies on grep/read/wc and the test suite.

Project markdown rules (one-sentence-per-line, compact tables, sequential numbering, fenced-code languages) enforced by rumdl. Load when writing or editing markdown — contains rules that differ from standard markdownlint defaults.

Authoring and reviewing Mermaid diagrams — pitfall categories (semicolons, angle-bracket tokens, quoted headings), renderer verification, and state-machine disambiguation with note blocks. Load when authoring or reviewing Mermaid diagrams in any doc type.

Fast Pi CLI reproduction workflow for this repo. Use when debugging extension behavior through the real pi executable, especially for Anthropic OAuth failures, prompt shaping, request payload inspection, or validating changes without waiting on manual retries.

Reference for the Pi coding agent's turn/tool execution model and extension event lifecycle. Use when designing extension timing (when to flush, notify, or intercept), understanding event sequencing, or reasoning about what the agent sees between turns. Includes the verified lifecycle diagram, event handler capabilities, message delivery mechanics, and empirical session-data patterns.

Vitest mock patterns (vi.mock, vi.hoisted, vi.fn reset), assertion strategy, and TDD planning rules. Load when writing or debugging tests.
