+# Web Hooks
+
+## Recommended PostToolUse Hooks
+
+Prefer project-local tooling. Do not wire hooks to remote one-off package execution.
+
+### Format on Save
+
+Use the project's existing formatter entrypoint after edits:
+
+```json
+{
+  "hooks": {
+    "PostToolUse": [
+      {
+        "matcher": "Write|Edit",
+        "command": "pnpm prettier --write \"$FILE_PATH\"",
+        "description": "Format edited frontend files"
+      }
+    ]
+  }
+}
+```
+
+Equivalent local commands via `yarn prettier` or `npm exec prettier --` are fine when they use repo-owned dependencies.
+
+### Lint Check
+
+```json
+{
+  "hooks": {
+    "PostToolUse": [
+      {
+        "matcher": "Write|Edit",
+        "command": "pnpm eslint --fix \"$FILE_PATH\"",
+        "description": "Run ESLint on edited frontend files"
+      }
+    ]
+  }
+}
+```
+
+### Type Check
+
+```json
+{
+  "hooks": {
+    "PostToolUse": [
+      {
+        "matcher": "Write|Edit",
+        "command": "pnpm tsc --noEmit --pretty false",
+        "description": "Type-check after frontend edits"
+      }
+    ]
+  }
+}
+```
+
+### CSS Lint
+
+```json
+{
+  "hooks": {
+    "PostToolUse": [
+      {
+        "matcher": "Write|Edit",
+        "command": "pnpm stylelint --fix \"$FILE_PATH\"",
+        "description": "Lint edited stylesheets"
+      }
+    ]
+  }
+}
+```
+
+## PreToolUse Hooks
+
+### Guard File Size
+
+Block oversized writes from tool input content, not from a file that may not exist yet:
+
+```json
+{
+  "hooks": {
+    "PreToolUse": [
+      {
+        "matcher": "Write",
+        "command": "node -e \"let d='';process.stdin.on('data',c=>d+=c);process.stdin.on('end',()=>{const i=JSON.parse(d);const c=i.tool_input?.content||'';const lines=c.split('\\n').length;if(lines>800){console.error('[Hook] BLOCKED: File exceeds 800 lines ('+lines+' lines)');console.error('[Hook] Split into smaller modules');process.exit(2)}console.log(d)})\"",
+        "description": "Block writes that exceed 800 lines"
+      }
+    ]
+  }
+}
+```
+
+## Stop Hooks
+
+### Final Build Verification
+
+```json
+{
+  "hooks": {
+    "Stop": [
+      {
+        "command": "pnpm build",
+        "description": "Verify the production build at session end"
+      }
+    ]
+  }
+}
+```
+
+## Ordering
+
+Recommended order:
+1. format
+2. lint
+3. type check
+4. build verification
