Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Fable 5.1 $0.00049 $0.03907
Opus 5.5 $0.00020 $0.01563
Sonnet 5.5 $0.00010 $0.00781

Security

Grade A, and why

claude-agent-sdk-ts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 32 executable files (snippets/agent-v1/basic-query.ts, snippets/agent-v1/query-with-queue.ts, snippets/agent-v1/query-with-resume.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 485 lines — stays where its author put it; the contents beside it link to each section on GitHub.

TypeScript Claude Agent SDK Builder

Build AI agents using the Claude Agent SDK in TypeScript by referencing code snippets that demonstrate both V1 (query()) and V2 (session-based) API patterns.

How It Works

  1. Choose your API: V1 for scripts/batch processing, V2 for interactive apps
  2. Browse the snippet catalog below or in snippets/
  3. Copy the snippets you need into your project
  4. Customize the copied code for your use case

Snippets are bundled in this skill's snippets/ directory.

Authentication

The Claude Agent SDK automatically uses Claude Code's authentication - no API key configuration required if you're logged into Claude Code.

How it works:

  1. The SDK looks for OAuth tokens in ~/.claude/ (created when you run claude login)
  2. Falls back to ANTHROPIC_API_KEY environment variable if set
  3. No code changes needed - authentication is handled automatically

Check your auth status:

claude auth status

If not authenticated:

claude login

Alternative Providers (Bedrock, Vertex AI, Azure)

The SDK also supports cloud provider APIs. Set environment variables:

Amazon Bedrock:

export CLAUDE_CODE_USE_BEDROCK=1
export AWS_REGION=us-west-2
export AWS_PROFILE=your-profile  # Optional: specify named credentials profile
# Or uses default AWS credentials (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, or IAM role)

Google Vertex AI:

export CLAUDE_CODE_USE_VERTEX=1
export CLOUD_ML_REGION=us-east5
export ANTHROPIC_VERTEX_PROJECT_ID=your-project-id
# Uses your Google Cloud credentials

Azure:

export CLAUDE_CODE_USE_AZURE=1
export AZURE_OPENAI_ENDPOINT=https://your-resource.openai.azure.com
# Uses your Azure credentials

Note: If deploying to a server without Claude Code, set ANTHROPIC_API_KEY in your environment (or use Bedrock/Vertex/Azure as above).

When to Use Claude Agent SDK

Use Claude Agent SDK when you want:

  • Quick setup with minimal boilerplate
  • Out-of-the-box Claude Code capabilities
  • Pre-built tool ecosystem with MCP server integration
  • Session management and multi-turn conversations
  • Hook system for tool auditing and control

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
