# Claude Agent SDK Skill (Auto-Updated)

A self-updating Claude Code skill for building AI agents with the Claude Agent SDK — covering both [TypeScript](https://github.com/anthropics/claude-agent-sdk-typescript) and [Python](https://github.com/anthropics/claude-agent-sdk-python).

**SDK Version**: TypeScript v0.2.141 | Python v0.2.82 | **This skill is auto-updated**: 2026-05-17

## What It Does

- Complete API reference for both TypeScript and Python SDKs: `query()`, hooks, subagents, MCP, permissions, sandbox, structured outputs, sessions
- Auto-correction rules that fire when editing `*agent*.ts` or `*agent*.py` files
- Known issue prevention with links to real GitHub issues
- Keeps itself up to date via a daily automated pipeline

## Why Auto-Update?

The Claude Agent SDK is pre-1.0 (`v0.2.x`) — APIs break frequently, functions get renamed, parameters change. A static skill would teach Claude outdated patterns that produce broken code. The pipeline keeps this skill accurate by tracking version bumps, researching new issues, and updating rules daily. Without it, advice written for `v0.2.30` silently becomes wrong when the SDK moves to `v0.3.0`.

## Installation

Clone into your Claude Code skills directory:

```bash
git clone https://github.com/xiaolai/claude-agent-sdk-skill-autoupdated ~/.claude/skills/claude-agent-sdk-skill-autoupdated
```

Claude Code loads it automatically. To pull the latest updates later:

```bash
cd ~/.claude/skills/claude-agent-sdk-skill-autoupdated && git pull
```

That's it — no API keys, no pipeline setup, no cost. You get a constantly up-to-date SDK skill maintained by the automated pipeline.

Optional: auto-update daily at 09:00 UTC (after the pipeline runs at 08:00):

```bash
(crontab -l 2>/dev/null; echo "0 9 * * * cd ~/.claude/skills/claude-agent-sdk-skill-autoupdated && git pull -q") | crontab -
```

## TypeScript vs Python SDK

Both SDKs wrap the Claude Code CLI and share the same core concepts, but they differ in architecture and feature surface.

### Architecture

| | TypeScript | Python |
|---|---|---|
| **Entry point** | `query()` only | `query()` + `ClaudeSDKClient` |
| **Multi-turn** | Not built-in (new session per call) | `ClaudeSDKClient` keeps conversation alive |
| **Hooks** | Available via `query()` options | Require `ClaudeSDKClient` (not available with standalone `query()`) |
| **Custom tools** | Available via `query()` options | Require `ClaudeSDKClient` |
| **Interrupts** | Not supported | `await client.interrupt()` |
| **Naming** | camelCase (`systemPrompt`, `maxTurns`) | snake_case (`system_prompt`, `max_turns`) |
| **Tool definition** | `tool(name, schema, handler)` function | `@tool(name, desc, schema)` decorator |
| **Options type** | `Options` interface | `ClaudeAgentOptions` dataclass |

### Python-Only Features

- **`ClaudeSDKClient`** — stateful client with `connect()`, `query()`, `receive_response()`, `interrupt()`, `disconnect()` lifecycle
- **`async with` context manager** — automatic connection cleanup
- **Multi-turn conversations** — send multiple queries in the same session without losing context
- **Runtime control** — `set_permission_mode()`, `set_model()`, `rewind_files()` mid-conversation
- **Extended thinking config** — `ThinkingConfig` types (`adaptive`, `enabled`, `disabled`) and `effort` option (`low`/`medium`/`high`/`max`)

### TypeScript-Only Features

- **V2 Session API** (preview) — `unstable_v2_createSession()` for persistent sessions with resume/fork
- **MCP tool annotations** — `annotations` field in tool definitions (v0.2.27+)
- **Plugin support** — `plugins: [{ type: "local", path: "..." }]` option
- **More known issues documented** — 22 tracked issues vs 5 for Python (reflects the older, larger codebase)

### Maturity

| | TypeScript | Python |
|---|---|---|
| **Version** | v0.2.141 | v0.2.82 |
| **GitHub stars** | ~800 | ~4,800 |
| **Open issues** | ~176 | ~570 |
| **Release cadence** | ~daily | ~daily |
| **Stability** | Pre-1.0, frequent changes | Pre-1.0, frequent changes |

Both SDKs are pre-1.0 and under active development. The Python SDK has a larger community but the TypeScript SDK has been around longer. Neither is "more stable" — expect breaking changes in both.

## Daily Pipeline

Runs via GitHub Actions at 08:00 UTC, or manually via `workflow_dispatch`.

### Pipeline Overview

The daily run has two paths depending on whether the SDK version changed.

```mermaid
flowchart LR
 M["Monitor bash · $0"]:::bash --> C{Version changed?}
 C -- Yes --> U["Update Agent LLM · ~$1"]:::llm
 U --> R["Research Agent LLM · ~$3"]:::llm
 C -- No --> R
 R --> V{"Verify bash · $0"}:::bash
 V -- Pass --> RP["Report Agent LLM · ~$0.25"]:::llm
 V -- Fail --> ME["Mending Agent LLM · ~$0.50"]:::llm
 ME --> V
 RP --> CO["Commit + Push"]:::bash

classDef bash fill:#e8f5e9,stroke:#43a047,color:#1b5e20
    classDef llm fill:#e3f2fd,stroke:#1e88e5,color:#0d47a1
```

### What the Research Agent Does

The research agent is the core of the pipeline. It runs daily and has three phases:

```mermaid
flowchart TB
 NI["npm install fetches latest SDK package"]:::bash --> A

subgraph A ["Part A — API Surface Audit"]
 direction LR
 A1["Read sdk.d.ts type definitions"]:::read --> A2["Extract options, methods, message types, hooks"]
 A2 --> A3["Compare against SKILL.md"]:::read
 A3 --> A4{"Missing APIs?"}
 A4 -- Yes --> A5["Add to SKILL.md"]:::write
 A4 -- No --> A6["Skip — already documented"]
 end

A --> B

subgraph B ["Part B — GitHub Issues Research"]
 direction LR
 B1["Fetch recent issues from SDK repo"]:::read --> B2["Deep-read body + all comments"]
 B2 --> B3{"Actionable workaround?"}
 B3 -- Yes --> B4["Add Known Issue or auto-correction rule"]:::write
 B3 -- No --> B5["Skip — record in state.json"]:::write
 end

B --> D

subgraph D ["Part C — Final Checks"]
 direction LR
 D1["Verify option tables match sdk.d.ts"]:::read --> D2["Verify hook event count matches"]
 D2 --> D3["Verify version strings consistent across files"]
 end

classDef bash fill:#e8f5e9,stroke:#43a047,color:#1b5e20
    classDef read fill:#fff3e0,stroke:#f57c00,color:#e65100
    classDef write fill:#e3f2fd,stroke:#1e88e5,color:#0d47a1
```

### What Gets Updated

    classDef target fill:#e8f5e9,stroke:#43a047,color:#1b5e20
```

### Step Details

| Step | What it does | Cost |
|------|-------------|------|
| **Monitor** | Checks npm registry + GitHub for version bumps, issue state changes, new bugs | $0 (bash) |
| **Update Agent** | Reads change report, updates version strings across all skill files | ~$1 (version bump only) |
| **Research Agent** | **Part A** reads `sdk.d.ts`, compares against SKILL.md, adds missing APIs. **Part B** scans GitHub issues, adds Known Issues or rules. **Part C** validates consistency. | ~$3 |
| **Verify** | Deterministic grep/jq checks on version strings and structure | $0 (bash) |
| **Mending Agent** | Reads verification failures, fixes what broke (up to 2 retries) | ~$0.50/attempt |
| **Report Agent** | Generates pipeline summary, updates cost log in README | ~$0.25 |

## Cost Log

| Date | SDK Version | Update | Research | Report | Total | Notes |
|------|-------------|--------|----------|--------|-------|-------|
| 2026-05-13 | — | $0.32 | — | $0.23 | **$0.55** | SDK v0.2.139→v0.2.140 |
| 2026-05-07 | TS v0.2.132 | — | ~$1.50 | — | **~$1.50** | API audit skipped (version unchanged); researched issues #237–#320; 21 already_documented, 63 skipped; no new KIs added (KI #55 is latest) |
| 2026-05-05 | TS v0.2.128 | $0.24 | — | — | **$0.24** | SDK v0.2.126→v0.2.128: sessionStoreFlush option, oauth_org_not_allowed error, SDKMessageOrigin type; GitHub API unavailable |
| 2026-05-03 | — | $0.18 | — | $0.24 | **$0.42** | SDK v0.2.126→v0.2.126 |
| 2026-05-02 | — | $0.16 | — | $0.24 | **$0.40** | SDK v0.2.126→v0.2.126 |
| 2026-04-27 | — | $0.26 | — | $0.24 | **$0.50** | SDK v0.2.119→v0.2.119 |
| 2026-04-10 | — | $0.24 | — | $0.23 | **$0.47** | SDK v0.2.97→v0.2.98 |

## How It Works

The daily pipeline runs via GitHub Actions on this repo. It costs the **maintainer** a few dollars per day in LLM usage. The pipeline commits updated skill files directly to this repo.

**As a user**, you just `git pull` to get the latest. You never run the pipeline yourself and pay nothing. You don't need Node.js, npm, or anything in the `agent/` directory — that's maintainer-only infrastructure.

| Role | What you do | Cost |
|------|------------|------|
| **User** | `git clone` / `git pull` | Free |
| **Maintainer** | Runs the CI pipeline | ~$3–6/day |

## Pipeline Prerequisites (maintainer only)

- [Claude Code CLI](https://docs.anthropic.com/en/docs/claude-code) installed on the runner
- GitHub secret: `CLAUDE_CODE_OAUTH_TOKEN` (subscription) or `ANTHROPIC_API_KEY`
- `gh` CLI authenticated (for issue scanning)
