Improves the repo's agent guidance: distills the always-required `studio-best-practices` skill into `apps/studio/CLAUDE.md`, tunes every skill description for reliable triggering, and mechanically enforces the generated-files rule. Grounded in Anthropic's official CLAUDE.md guidance (see justifications below). ## The main change: Studio CLAUDE.md gets a Code style section **Why:** `studio-best-practices` was a skill that instructed agents to *always* load it before any Studio code work. Anthropic's guidance draws the line as: sometimes-relevant guidance → skill (loaded on demand); always-relevant guidance → CLAUDE.md. A skill that must always load has failed the test for being a skill — it costs a tool-call round trip and, worse, silently does nothing in sessions that forget to load it. Since `apps/studio/CLAUDE.md` is lazy-loaded only when an agent touches Studio files, inlining is properly scoped: non-Studio sessions never pay for it. **Why not verbatim:** the skill was 175 lines, mostly ❌/✅ worked examples teaching practices models already know. Inlining it whole would push the file past the ~200-line point where Anthropic warns rules start getting lost. Instead each section was distilled to the rule it exists to enforce — e.g. the loading/error/success section kept its code block because the *shape* (early returns at top level, flat `&&` chains inline) is the prescription, and prose loses it. **The framing that makes the generic rules earn their place:** models default to matching surrounding code, and not all existing Studio code follows these practices. The section opens with "older Studio code predates some of these conventions — follow them rather than mirroring nearby legacy patterns," which converts otherwise-redundant React advice into an explicit instruction to break from local precedent. One rule was added that the old skill lacked: `useEffect` is for external-system sync only (~364 Studio files contain effects, many in patterns we don't want copied). **Changed:** - `apps/studio/CLAUDE.md` — new Code style section (84 lines total, within budget); skills table no longer mandates a pre-load - `.claude/CLAUDE.md` — dropped `pnpm install` from commands (guessable; Anthropic's test: "would removing this cause mistakes?") **Removed:** - `.claude/skills/studio-best-practices/` — fully absorbed; its cross-references to other skills were already covered by the skills routing table ## Skill description tuning Descriptions are the only signal an agent sees before deciding to load a skill, and the observed failure mode is under-triggering on tasks that don't name the skill. Nine descriptions reworded: front-loaded matchable keywords, added incidental-trigger cases (e.g. a new feature that adds copy is a `copywriting` moment), and disambiguated overlaps (`vitest` is now the API reference deferring to `studio-testing` for strategy). The `safe-sql-execution` rewrite was additionally validated with skill-creator's trigger-eval loop against 20 realistic queries: held-out test accuracy 54% → 71%, with zero false triggers across all iterations. (`vitest` shows under `.agents/` because `.claude/skills/vitest` symlinks there.) ## Generated-files enforcement **Added:** `permissions.deny` rules in `.claude/settings.json` for the six generated-file globs the root CLAUDE.md already lists. CLAUDE.md prose is advisory; permission rules are mechanical and also gate sandboxed Bash writes. (Verified live: the rule blocked an unintended regeneration of `database-types.ts` during testing.) ## To test - CI: prettier + typos checks pass (docs-only + settings change, no app code) - In a fresh Claude Code session in the repo: ask it to edit `apps/studio/routeTree.gen.ts` — should be denied by the new permission rule - Ask it to do any Studio UI task — it should pick up the Code style rules from `apps/studio/CLAUDE.md` without loading a best-practices skill <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Updated development guidance for testing, copywriting, SQL safety, telemetry, queries, error handling, and toolbar reviews. * Restructured Vitest references into clearer tables and improved formatting across several guides. * Added Studio code-style conventions and clarified when task-specific guidance should be applied. * Removed outdated Studio best-practices guidance. * **Chores** * Added safeguards preventing edits to generated and protected files. * Simplified the documented development command sequence. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Alaister Young <10985857+alaister@users.noreply.github.com>
