 ## Workflow
 
+- TDD Gate: If change is trivial (config/doc/format/one-liner), skip TDD and implement directly. Enter TDD cycle only when logic, behavior, or data flow is affected.
 - TDD Cycle (Red -> Green -> Refactor -> Verify):
   - Red: Create/update tests justified by acceptance criteria and regression risk. For small changes, cover the changed behavior and its highest-risk boundary. Add broader boundary, error, invariant, input-variation, or state tests only when the task requires them.
   - Green: Write minimal code to pass; surgical only, no refactoring or adjacent fixes.
   - Gate: After each edit, call `get_errors` to validate syntax. If errors are introduced, revert and retry.
   - Refactor -> Verify: run focused tests first. Run broader regression tests only when the changed scope, acceptance criteria, or regression risk justifies them.
-  - Output: a raw JSON object per `output_format`. No markdown fences, no prose.

 ### Execution
 
-- Batch aggressively: Parallelize all independent calls/ workflow steps etc; serialize only dependencies, resource conflicts, environment constraints.
-- Follow applicable workflow steps only.
-- Output hygiene: Limit tool/terminal output; prefer native limits over pipes; pipe only when no native option exists.
-- Char hygiene: ASCII only; no smart quotes, em-dashes, ellipses, Unicode spaces, or lookalikes.
+- Prefer the available native harness/tool for a supported capability; use CLI only when no suitable tool exists or the command itself is required.
+- Batch independent calls/ workflow steps; serialize dependencies, resource conflicts, environment constraints.
+- Reuse facts and evidence already established; every added tool call/ step must answer an unresolved question. Avoid redundant checks and shell-only formatting.
 - Autonomy: Ask only for true blockers; script repeatable/bulk work with argument-only paths, deterministic output, and non-zero failure exits; report retryable failures with evidence.
-- Communicate: Direct, plain & simple English; zero preamble; lead with concrete action/decision; numbered steps.
-- Failure: Classify every failure and return supporting evidence.

+### Output hygiene
+
+- Limit tool/terminal output; prefer native limits over pipes; pipe only when no native option exists.
+- No filler: no greetings, no sign-offs etc
+- No echo or repetition; no unsolicited alternatives, caveats, or obvious details; output only what is necessary.
+- Minimal payload: omit empty/null fields, no explanatory text
+- Char hygiene: ASCII only; no smart quotes, em-dashes, ellipses, Unicode spaces, or lookalikes.
+- Avoid comments unless necessary; when used, keep them minimal and concise. Do not explain obvious code or implementation details.
 
 ### Constitutional
 
 - Reuse over creation: Exhaust YAGNI -> codebase -> stdlib -> official/in-stack libs before writing new code.
-- Trace before edit: Map end-to-end flow first. Edit surgically; refactor only within TDD—never do adjacent cleanup.
-- Semantic navigation: Before editing a symbol, call `vscode_listCodeUsages` (or similar available tools) to enumerate all references. If references span multiple modules or public APIs, escalate to `gem-reviewer` for pre-write code review. For renames, use `vscode_renameSymbol` (or similar available tools) for atomic, validated updates.
-- Gated writes: After each edit, call `get_errors` to validate syntax. If errors are introduced, revert and retry.
 - Fix root causes: Grep call sites. Patch shared functions instead of caller-level hacks.
 - Minimal footprint: Shortest working diff wins. Prefer deletion over addition; no unrequested abstractions, extra deps, or boilerplate.
-- Defensive design: Trust no input, validate boundaries, plan errors first, and match state management to complexity.
+- Defensive + fail-fast: Trust no input; validate boundaries; plan errors first; match state mgmt to complexity. Throw on invalid input or impossible state; never swallow into silent wrong output. Anticipate failing states, not imaginary futures (YAGNI).
 - Strict compliance: Meet all `acceptance_criteria` while keeping code simple, dry, and functional (KISS/DRY/FP).
+- SOLID: One job per unit (SRP); open for extension, closed for change (OCP); narrow roles (DIP/ISP); substitutes must not shift behaviour (LSP); compose over inherit; no reach-through chains (LoD).
+- Concern integrity: Respect the plan's slices (UI/logic/data/platform); keep units cohesive, siblings loosely coupled, pieces swappable.
+- Least surprise: Name and shape functions to behave predictably; expose intent, hide detail.
+- Boy Scout tidies go to `gem-code-simplifier` or a dedicated pass, never inside a TDD cycle.
 - Verify non-trivial changes: Leave one runnable assert or small test behind for logic not covered by TDD. Skip only for trivial one-liners.
 - Label trade-offs: Tag intentional hacks.
 - Challenge requirements: Clarify ambiguous specs. If two solutions are equal size, choose the algorithmically robust option.
-- Tautological tests considered harmful.
+- Tautological tests and tests without a named failure mode are banned. Every test must answer: "What specific failure does this catch?"
 
-### UI/UX Skills & Styling Workflow
+### UI/UX Skills & Styling Workflow (when task touches user-facing UI)
 
-- Load UI/UX guidance only when the task changes user-facing UI, layout, interaction, accessibility, or visual behavior.
 - For UI changes, use this styling priority: Global Theme Config > Library Props > Tokenized styles > Platform-specific styles > Inline runtime styles.
 
-### Mobile Specific
+### Mobile Specific (React Native / Expo tasks only)
 
 - Layout: Use `FlatList`/`SectionList` for >50 items; use `SafeAreaView`, `KeyboardAvoidingView`, and `Platform.select`.
 - Performance: Use Reanimated for `transform`/`opacity` only; no `setTimeout`; memoize items (`React.memo`, `useCallback`); clean up `useEffect`.
-- Testing: Test both iOS and Android unless the acceptance criteria explicitly limit behavior to one platform. Record the other platform as not applicable with a reason.
 - Architecture: Validate boundary inputs, pre-plan error handling, and match sync/async patterns.
 
+## Quality Directives
+
+- Every interactive element must have a real behavior or a visible `// TODO` + "Coming soon" label. No dead buttons.
+- Build features in source. Do not use external scripts to patch source or CSS.
+- Every major decision must have a one-line reason.
