Expert Claude Agent SDK custom tool authoring capability pack for designing typed in-process tools with createSdkMcpServer, allowedTools scoping, isError handling, and privacy-safe rollout checklists aligned to official custom-tools documentation.

Expert capability pack for Agent SDK OpenTelemetry export using CLAUDE_CODE_ENABLE_TELEMETRY, OTLP exporters, and monitoring-usage reference variables documented for Claude Code CLI subprocesses.

Expert Claude Agent SDK MCP integration capability pack for designing, reviewing, and rolling out Agent SDK MCP integration with source-backed checklists, production rules, and privacy-safe output contracts.

Expert Claude Agent SDK session storage capability pack for designing, reviewing, and rolling out Agent SDK session storage with source-backed checklists, production rules, and privacy-safe output contracts.

Expert Claude Agent SDK subagent orchestration capability pack for designing, reviewing, and rolling out Agent SDK subagent orchestration with source-backed checklists, production rules, and privacy-safe output contracts.

Production-oriented quickstart for the Claude Agent SDK: project bootstrap with agent-sdk-dev plugin, query loops, permissions, observability hooks, and deployment guardrails.

Isolate Claude Agent SDK tenants in shared containers using documented options: per-tenant cwd, settingSources disabled, CLAUDE_CONFIG_DIR, CLAUDE_CODE_DISABLE_AUTO_MEMORY, and per-tenant egress rules from official hosting documentation.

How to design custom tools for the Claude Agent SDK: in-process tool definitions with typed input schemas, permission scoping, structured isError results, and when to reach for an external MCP server instead.

Connect MCP servers to Claude Agent SDK applications: stdio, HTTP, SSE configs, OAuth, managed policy parity, and tool-search interaction.

An agent prompt for taking Claude Agent SDK apps to production: choosing the SDK vs CLI vs Managed Agents surface, least-privilege tool and permission scoping, session persistence, cost tracking, OpenTelemetry, and isolated hosting.

A practical walkthrough of using Agent Skills in the Claude Agent SDK: how skills are discovered from the filesystem via settingSources, the skills option to enable or filter them, tool access, and troubleshooting discovery.

A practical walkthrough of defining in-process custom tools for the Claude Agent SDK with createSdkMcpServer and the tool helper, wiring them into query via mcpServers, allowing them, error handling, and returning images or structured data.

A practical walkthrough of token and spend accounting in the Claude Agent SDK. Read total_cost_usd from the result message, deduplicate parallel tool calls that share an assistant id, break spend down per model with modelUsage, sum cost across query() calls yourself, and read cache_creation/cache_read tokens.

A practical walkthrough of mirroring Claude Agent SDK session transcripts to external storage: the SessionStore interface, the SessionKey shape, resuming across hosts, reference adapters for S3/Redis/Postgres, and behavior notes.

A practical walkthrough of file checkpointing in the Claude Agent SDK: enabling it, capturing checkpoint UUIDs from user messages, rewinding files by resuming the session, multiple restore points, and the limitations you must know.

A practical walkthrough of exporting OpenTelemetry traces, metrics, and events from the Claude Agent SDK: enabling telemetry, configuring OTLP exporters, reading agent spans, linking traces to your app, and controlling sensitive data.

A practical walkthrough of least-privilege permission design in the Claude Agent SDK. Learn the evaluation order (hooks → deny → mode → allow → canUseTool), how allowedTools and disallowedTools differ, the six permission modes, and how to lock an agent to a fixed tool surface with dontAsk.

A practical walkthrough of loading local plugins in the Claude Agent SDK: the plugins option with type local and a path, what plugins bundle (skills, agents, hooks, MCP servers), verifying loads via the init message, and invoking namespaced plugin skills.

A practical walkthrough of securely deploying Claude Agent SDK applications: the prompt-injection threat model, isolation options (sandbox runtime, containers, gVisor, VMs), least privilege, the proxy credential pattern, and filesystem controls.

A practical walkthrough of slash commands in the Claude Agent SDK. Read the slash_commands array from the system init message, dispatch a command by placing it in the prompt string, handle built-ins like /compact and /clear, and author your own as SKILL.md files with allowed-tools frontmatter.

A practical walkthrough of real-time streaming in the Claude Agent SDK: enabling partial messages, reading StreamEvent text and tool-call deltas, the message flow, and building a streaming UI.

A practical walkthrough of structured outputs in the Claude Agent SDK: defining a JSON Schema via the outputFormat option, reading validated structured_output, type-safe schemas with Zod or Pydantic, and handling validation failures.

A practical walkthrough of subagents in the Claude Agent SDK: defining them programmatically with the agents option and AgentDefinition, context isolation, parallelization, tool restrictions, invocation, and resuming.
