+# Naming conventions
+
+## No abbreviations
+
+Use full words. Abbreviations save keystrokes but cost comprehension.
+
+- ✅ `position`, `request`, `response`, `configuration`, `message`
+- ❌ `pos`, `req`, `res`, `config`, `msg`
+
+**Exception:** trivial predicate callbacks where the variable is used once and the type is obvious: `.map(c => c.trim())`, `.filter(n => n > 0)`.
+
+## Unit-of-measure suffixes
+
+Numeric variables must include the unit as a suffix. Abbreviations are fine when clearly understandable.
+
+- ✅ `durationMs`, `timeoutMs`, `delaySec`, `CELL_HEIGHT_PX`, `fontSizeRem`
+- ❌ `duration`, `timeout`, `delay`, `CELL_HEIGHT`, `fontSize`
+
+## Verb-led function names
+
+Functions start with a transitive verb that describes the action.
+
+- ✅ `fetchResults`, `buildPayload`, `resolveColor`, `parseCommitTitle`
+- ❌ `results`, `payload`, `color`, `commitTitle`
+
+Common verbs: `build`, `create`, `compute`, `fetch`, `find`, `get`, `load`, `parse`, `resolve`, `validate`.
+
+## Boolean naming
+
+Booleans start with `is`, `has`, `should`, or `does` (with conjugations: `was`, `are`, `have`, `did`).
+
+- ✅ `isVisible`, `hasChildren`, `shouldRetry`, `doesExist`, `wasProcessed`
+- ❌ `visible`, `children`, `retry`, `exists`, `processed`

 - Only document params when the name alone doesn't convey purpose or constraints
 
+## Naming
+
+Follow the naming rules in `_data/naming-conventions.md`: no abbreviations, unit-of-measure suffixes on numerics, verb-led function names, boolean prefixes (`is`, `has`, `should`, `does`).
