SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve? Claude Code has hundreds of features—30+ tools, 60+ commands, 50+ CLI flags, 80+ environment variables, hooks, MCP, plugins, and deployment options—scattered across dozens of official docs. This Skill consolidates them into a topic-indexed reference so you get accurate answers about Claude Code capabilities without searching documentation manually. ## Core Features & Use Cases - Topic-Based Lookup: Invoke with a topic (hooks, mcp, subagents, permissions, token-optimization, deployment, env-vars) to load only the relevant reference file. - Complete Coverage: References cover the extension system (Skills/Subagents/Agent Teams/MCP/Plugins/Hooks/Channels), configuration (settings priority, permission modes, sandboxing), automation (SDK mode, --bare, scheduling), cloud deployment (Bedrock/Vertex/Foundry), and 12 token optimization strategies. - PhyCool Cron Templates: Includes ready-to-use scheduled task templates (tech debt sweep, skill sync audit, token usage report) with [SILENT] notification semantics. - Use Case: When you ask "how do I configure permission rules for Bash commands" or "which environment variables control MCP timeouts", the Skill loads the matching reference and returns precise syntax and examples. ## Quick Start Ask the claude-tools skill to explain how hooks work and which events can block tool execution.

Frequently Asked Questions about claude-tools

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I configure permission rules in Claude Code?▼

Permission rules use patterns like Bash(npm run *) or Read(./secrets/**) in settings.json under permissions.allow, deny, or ask. Evaluation order is deny first, then ask, then allow, with the first match winning.

What hook events does Claude Code support?▼

Claude Code supports 25 hook events including SessionStart, UserPromptSubmit, PreToolUse, PostToolUse, Stop, and SessionEnd. Blocking-capable events like PreToolUse can exit with code 2 to prevent an action and feed stderr back to Claude.

How do I reduce token usage in Claude Code?▼

Use /clear between unrelated tasks, delegate research to subagents, move workflows into skills with disable-model-invocation, prefer CLI tools over MCP servers, and lower effort levels for simple tasks. The token-optimization reference lists 12 strategies across five categories.

Can Claude Code run on AWS Bedrock or Google Vertex?▼

Yes, set CLAUDE_CODE_USE_BEDROCK=1 or CLAUDE_CODE_USE_VERTEX=1 with the corresponding region and model environment variables. Always pin model versions with ANTHROPIC_DEFAULT_OPUS_MODEL and related variables when using cloud providers.

What is the difference between subagents and agent teams?▼

Subagents run in isolated contexts and report results back to the main conversation, while agent teams are fully independent Claude instances that coordinate via a shared task list and mailbox. Agent teams cost roughly 7x more tokens than a single agent.

Why are my MCP tools consuming too much context?▼

MCP tool schemas load into every request by default. Enable Tool Search with ENABLE_TOOL_SEARCH to defer schemas until needed, disable idle servers via /mcp, and cap responses with MAX_MCP_OUTPUT_TOKENS.
