# AI Skills

> Task-focused skill files for AI coding agents working with @bitrix24/b24jssdk.

## Overview

AI coding agents (Claude Code, Cursor, GitHub Copilot) can load task-focused skill files from the `skills/` directory instead of reading the entire repository. Each skill covers one concern — pick only what the current task requires.

## Available Skills

| Skill | When to use |
| --- | --- |
| `b24jssdk-core` | First skill to load — entry point pick (B24Hook / B24Frame / B24OAuth), boot/teardown, error taxonomy, hardErrorCodes / softErrorCodes / retryOnNetworkError tuning |
| `b24jssdk-rest` | actions.v{2,3}.*.make() — call / batch / callList / fetchList / batchByChunk; AjaxResult shape; v3 method whitelist |
| `b24jssdk-filtering` | v2 prefix-keyed filter vs v3 array-of-triples; operators; dates via Text.toB24Format; order-stripping rule of callList |
| `b24jssdk-frame-ui` | iframe-only managers: slider / dialog (selectUser/Users/CRM/Access) / parent / placement (with setValue) / options / auth |
| `b24jssdk-helpers` | useB24Helper, B24HelperManager, Pull client, currency formatting, app/user options |
| `b24jssdk-recipes` | 12 end-to-end TypeScript mini-apps, type-checked in CI via pnpm run skills:typecheck |
| `b24jssdk-vibecode` | When to combine the SDK with the VibeCode HTTP API |

## Usage

Load a skill by referencing it in the agent's context. Examples:

**Claude Code** — add to the system prompt or reference inline:

```text
@skills/b24jssdk-core
```

**Cursor / Windsurf** — use `@docs` or drag the skill file into the chat context.

**GitHub Copilot** — attach the skill file as a workspace document or paste its path into the chat.

Skills are plain Markdown files and can be read directly from `skills/<name>/SKILL.md` in the repository root.

## Loading Order

Always start with `b24jssdk-core` — it covers entry point selection and SDK lifecycle, which every other skill assumes. Then add topic-specific skills based on the task:

1. `b24jssdk-core` (always first)
2. `b24jssdk-rest` — if making REST calls
3. `b24jssdk-filtering` — if building filters or list queries
4. `b24jssdk-frame-ui` — if working inside an iframe app
5. `b24jssdk-helpers` — if using helper utilities or Pull
6. `b24jssdk-recipes` — for complete end-to-end examples

Do not load all skills at once — the descriptions are designed for selective consumption to keep the context focused.
