+## Tool Usage
+
+### Project overview
+```bash
+tokei src/ shared/                  # language breakdown
+```
+
+### Find files — fd over find
+```bash
+fd -e ts src/                       # all .ts files
+fd -g '*.test.mjs' tests/           # test files
+# ❌ find src -name "*.ts" generates 43k chars for 1,332 files
+```
+
+### Search content — rg
+```bash
+rg 'provider' src/ -t ts            # search TypeScript
+rg 'GEMINI' .env.example            # find env keys
+```
+
+### Structural search — ast-grep
+```bash
+ast-grep run --lang ts --pattern 'import { $A } from "$B"' src/
+ast-grep run --lang ts --pattern 'z.string()' src/
+```
+
+### Query JSON/config
+```bash
+jq '.dependencies' package.json
+jq 'keys' shared/providerModels.js 2>/dev/null
+```
+
+### Safe string replace — sd over sed
+```bash
+sd 'gemini-2.5-flash' 'gemini-3-flash' src/anthropicCompatProxy.ts
+```
+
+## Running Tests
+
+```bash
+node --test tests/*.test.mjs
+```
