Read the nerve-dev skill for sense file structure and conventions: \`cat node_modules/@uncaged/nerve-skills/nerve-dev/SKILL.md\`

Implement the sense following the patterns from existing senses and the skill guide.

File structure for each sense:
- \`senses/<name>/src/index.ts\` — TypeScript source with proper types; import schema as \`./schema.ts\`
- \`senses/<name>/src/schema.ts\` — Drizzle schema (TypeScript)
- \`senses/<name>/migrations/\` — Drizzle migration files (at sense root, not inside src/)
- \`senses/<name>/package.json\` — with esbuild build script (see below)
- \`senses/<name>/index.js\` — bundled output generated by \`pnpm build\` (do NOT edit by hand)

package.json template for each sense:
\`\`\`json
{
  "name": "sense-<name>",
  "version": "0.0.1",
  "private": true,
  "type": "module",
  "scripts": {
    "build": "esbuild src/index.ts --bundle --platform=node --format=esm --outfile=index.js --packages=external"
  },
  "devDependencies": {
    "@types/node": "^22.0.0",
    "esbuild": "^0.27.0",
    "typescript": "^5.7.0"
  },
  "pnpm": {
    "onlyBuiltDependencies": ["esbuild"]
  }
}
\`\`\`

After creating all files, run inside the sense directory:
\`\`\`
pnpm install --no-cache && pnpm build
\`\`\`

This generates the bundled \`index.js\` at the sense root that the daemon loads.

Then update nerve.yaml and run any required migrations.`;
