Adding a New Tool

1. Create file: src/tools/{category}/{action}.ts

import { z } from 'zod';
import { defineTool, repoParam } from '../define.js';

const schema = z.object({
    repo: repoParam,
    // ... your params
});

export const myTool = defineTool({
    name: 'my_tool',
    description: 'What this tool does',
    schema,
    category: 'my-category',
    read_only: true,
    handler: async (input, ctx) => {
        return ctx.provider.repository.someMethod(input.repo, ...);
    },
});

2. Export from category index: src/tools/{category}/index.ts
3. Add to allTools: src/tools/index.ts
