Pb Extend is an agent skill from spinspire/pocketbase-sveltekit-starter. Extend PocketBase with custom hooks and routes in JS or Go. Use when user wants to add custom API routes, modify PocketBase behavior, or add server-side logic.

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Backend development. The repository describes itself as: a starter project to build a SvelteKit frontend with PocketBase backend. The licence is MIT.

When your agent uses it

User wants to add custom API routes
Modify PocketBase behavior
Add server-side logic

Example prompts

“/pb-extend”

Requirements

Pre-approved tools (allowed-tools): Bash

What it can do on your machine

Read from SKILL.md and the folder at commit 66f6dee. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Bash
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript and go).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- pocketbase.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Pb Extend loads about 689 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 117 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~42
When it runs · the whole SKILL.md, loaded when a task matches: ~689

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
```
allowed-tools: Bash
```

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

PocketBase Extending

Reference: https://pocketbase.io/docs/js-overview/ | https://pocketbase.io/docs/go-overview/

Extend PocketBase with custom hooks and routes in JS or Go.

JS Hooks (pb_hooks/)

Drop *.pb.js files in pb_hooks/:

javascript

// pb_hooks/myhook.pb.js
/// <reference path="../pb_data/types.d.ts" />

router.api.post('/custom-route', async (e) => {
  const body = e.request.body
  // ... process
  return e.json({ result: 'ok' })
})

// On record create
onRecordCreateRequest((e) => {
  if (!e.record.get('email').endsWith('@company.com')) {
    return e.badRequest('Use company email')
  }
  return e.next()
})

Rules:

Always call e.next() / e.Next() in hooks
Variables outside handlers are undefined at runtime
Use require() for shared config (CJS only, no ESM)

Go Hooks (migrations/)

Versioned migrations in migrations/:

package migrations

import (
  "github.com/pocketbase/pocketbase/migrations"
  "github.com/pocketbase/pocketbase/tools/types"
)

func init() {
  migrations.Register(func(app *pocketbase.App) error {
    // Custom logic
    return nil
  }, func(app *pocketbase.App) error {
    // Rollback logic
    return nil
  })
}

Custom Routes

javascript

// Add to pb_hooks
router.api.post('/api/myapp/send-email', async (e) => {
  const data = await e.request.json()
  await sendEmail(data.to, data.subject)
  return e.json({ sent: true })
}, middleware.RequireAuth())

Key Hook Events

Event	Purpose
`onRecordCreateRequest`	Before record creation
`onRecordUpdateRequest`	Before record update
`onRecordDeleteRequest`	Before record deletion
`OnRecordEnrich`	Shape response (incl. realtime)
`OnRecordRequest`	HTTP-only response shaping
`OnBeforeServe`	Modify router before serving

Migrations

System fields: Collections created via migration files must include created and updated system fields.

Auto-migrate: Collections changed via Admin UI auto-generate migrations in pb_migrations/

Manual JS migration:

javascript

// pb_migrations/1700000000_seed_data.js
migrate((up, down) => {
  up((db) => {
    db.createCollection('categories', { /* ... */ })
  })
  down((db) => {
    db.dropCollection('categories')
  })
})

Useful Settings

javascript

// Read at runtime
const settings = require('../pb_settings/config.js')

// Access app in hooks
router.use(async (e) => {
  const app = e.app
  // ...
})
