Validates recently written code against project-specific development guidelines from .trellis/spec/. Identifies changed files via git diff, discovers applicable spec modules, runs lint and typecheck, and reports guideline violations. Use when code is written and needs quality verification, to catch context drift during long sessions, or before committing changes.
Pre-commit quality checklist covering lint, typecheck, tests, code-spec sync, API changes, database migrations, cross-layer verification, and manual testing. Blocks commit if infra or cross-layer specs lack executable depth. Use when code is written and tested but not yet committed, before submitting changes, or as a final review before git commit.

Analyzes changed files and improves unit test coverage using project-specific testing conventions from .trellis/spec/ unit-test specs. Determines test scope (unit vs integration vs regression), adds or updates tests following existing patterns, and runs validation. Use when code changes need test coverage, after implementing a feature, after fixing a bug, or when test gaps are identified.

Complete guide for creating RStudio Playwright tests in TypeScript. Covers critical rules, stable selectors, code patterns, conventions, and review checklists. Use when writing, reviewing, or migrating Playwright tests for RStudio.
How to run RStudio Playwright tests in Desktop and Server modes. Use this skill whenever the user asks to run, execute, or launch Playwright tests against RStudio - whether on Desktop (local) or Server (remote). Also use when the user asks about the test command, environment variables, or how to point tests at a server URL. Trigger on phrases like "run the test", "execute on server", "run it on desktop", "run against <IP>", or any request involving npx playwright test for the RStudio test suite.

Create and modify Excel workbooks with mandatory deterministic Python verification of workbook structure, required sheets, populated columns, and sample counts before reporting completion.
Edit Excel workbooks only after anchored preflight audit, then require deterministic Python/openpyxl post-write proof that every requested criterion is satisfied or explicitly reconciled before finalizing.
Use a deterministic Python/openpyxl inspection pass to verify workbook structure, counts, marked rows, and output-file existence when delegated spreadsheet summaries seem inconsistent.
