Source-backed guide for scoping MCP servers, tools, permissions, hooks, and memory when building Claude Code subagents for focused review, research, and implementation workflows.

A practical walkthrough of structuring CLAUDE.md across a monorepo: how files load up the directory tree and on demand in subdirectories, path-scoped rules, imports, excluding other teams' files, and keeping per-package context lean.

A practical walkthrough of tracking token usage and cost in the Claude Agent SDK: the result message total_cost_usd estimate, per-step and per-model usage, deduplicating parallel tool calls, accumulating across calls, and cache tokens.

A practical walkthrough of Claude Code deep links: the claude-cli:// URL scheme, how to build links with repo, cwd, and prompt parameters, embedding them in runbooks and alerts, and the safety model where prompts are inert until you press Enter.

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 running Claude Code non-interactively with claude -p: bare mode, output formats (text, json, stream-json), JSON schema output, piping stdin, auto-approving tools, and authentication for scripts and CI.

Practical checklist for reviewing remote MCP server authorization, resource indicators, bearer-token handling, HTTPS transport, PKCE, and token passthrough risks before connecting an AI client.

Practical guide for checking MCP protected resource metadata, authorization server discovery, resource indicators, token audience binding, and 401 challenge behavior before trusting a remote MCP server.

Source-backed guide for converting OpenAI Agents SDK traces into regression eval cases, trace grades, tool-call assertions, and release checks for agentic workflows.

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 permission design in the Claude Agent SDK: the evaluation order (hooks, deny, mode, allow, canUseTool), allow/deny rules, permission modes, the canUseTool callback, and locking down an agent.

A practical walkthrough of Claude Code permission modes for teams: what each mode allows, how to switch and default them, protected paths, and how administrators enforce or lock modes with managed settings.

Source-backed guide for using Playwright traces, screenshots, snapshots, network events, console logs, and action timelines as evidence for AI-assisted frontend debugging.

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 managing Claude Code sessions: resuming with --continue, --resume, and --from-pr, naming sessions, using the session picker, branching to try a different approach, and where transcripts are stored.

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 using slash commands in the Claude Agent SDK: discovering available commands from the init message, sending commands in the prompt, built-in commands like compact and clear, and defining custom commands on the filesystem.

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.
