Skills: Model-invoked extensions in ~/.claude/skills/ (personal) or .claude/skills/ (project). Three-level progressive disclosure. Max 500 lines.

Sub-agents: Specialized assistants via Task(subagent_type="..."). Own 200K context. Cannot spawn sub-agents. Use /agents command.

Plugins: Reusable bundles in .claude-plugin/plugin.json. Include commands, agents, skills, hooks, MCP servers.

Commands: User-invoked via /command. Parameters: $ARGUMENTS, $1, $2. File refs: @file.

Hooks: Events in settings.json. PreToolUse, PostToolUse, SessionStart, SessionEnd, PreCompact, Notification.

Memory: CLAUDE.md files + .claude/rules/*.md. Enterprise to Project to User hierarchy. @import syntax.

Settings: 6-level hierarchy. Managed to file-managed to CLI to local to shared to user.

Sandboxing: OS-level isolation. Filesystem and network restrictions. Auto-allow safe operations.

Headless: -p flag for non-interactive. --allowedTools, --json-schema, --agents for automation.

Progressive Disclosure Architecture

Level 1 (Metadata): Name and description loaded at startup, approximately 100 tokens per Skill

Level 2 (Instructions): SKILL.md body loaded when triggered, under 5K tokens recommended

Level 3 (Resources): Additional files loaded on demand, effectively unlimited

Required Format

Create a SKILL.md file with YAML frontmatter containing name in kebab-case and description explaining what it does and when to use it in third person. Maximum 1024 characters for description. After the frontmatter, include a heading with the skill name, a Quick Start section with brief instructions, and a Details section referencing REFERENCE.md for more information.

Best Practices

• Third person descriptions (does not I do)
• Include trigger terms users mention
• Keep under 500 lines
• One level deep references
• Test with Haiku, Sonnet, Opus

Using /agents Command

Type /agents, select Create New Agent, define purpose and tools, press e to edit prompt.

File Format

Create a markdown file with YAML frontmatter containing name, description explaining when to invoke (use PROACTIVELY for auto-delegation), tools as comma-separated list (Read, Write, Bash), and model specification (sonnet). After frontmatter, include the system prompt.

Critical Rules

• Cannot spawn other sub-agents
• Cannot use AskUserQuestion effectively
• All user interaction before delegation
• Each gets own 200K context

Directory Structure

Create my-plugin directory with .claude-plugin/plugin.json, commands directory, agents directory, skills directory, hooks/hooks.json, and .mcp.json file.

Manifest (plugin.json)

Create a JSON object with name, description explaining plugin purpose, version as 1.0.0, and author object containing name field.

Commands

Use /plugin install owner/repo to install from GitHub.

Use /plugin validate . to validate current directory.

Use /plugin enable plugin-name to enable a plugin.

Two-Agent Pattern for Long Tasks

Initializer agent: Sets up environment, feature registry, progress docs

Executor agent: Works single features, updates registry, maintains progress

See reference/advanced-agent-patterns.md for details.

Orchestrator-Worker Architecture

Lead agent: Decomposes tasks, spawns workers, synthesizes results

Worker agents: Execute focused tasks, return condensed summaries

Context Engineering Principles

• Smallest set of high-signal tokens
• Just-in-time retrieval over upfront loading
• Context compaction for long sessions
• External memory files persist outside window

Tool Design Best Practices

• Consolidate related functions into single tools
• Return high-signal context-aware responses
• Clear parameter names (user_id not user)
• Instructive error messages with examples

Explore/Search Performance Optimization

When using Explore agent or direct exploration tools (Grep, Glob, Read), apply these optimizations to prevent performance bottlenecks with GLM models:

AST-Grep Priority

• Use structural search (ast-grep) before text-based search (Grep)
• Load moai-tool-ast-grep skill for complex pattern matching
• Example: sg -p 'class $X extends Service' --lang python is faster than grep -r "class.extends.Service"

Search Scope Limitation

• Always use path parameter to limit search scope
• Example: Grep(pattern="async def", path="src/moai_adk/core/") instead of Grep(pattern="async def")

File Pattern Specificity

• Use specific Glob patterns instead of wildcards
• Example: Glob(pattern="src/moai_adk/core/.py") instead of Glob(pattern="src//.py")

Parallel Processing

• Execute independent searches in parallel (single message, multiple tool calls)
• Maximum 5 parallel searches to prevent context fragmentation

Phase 1 Explore: Read files, understand structure, map dependencies

Phase 2 Plan: Use think prompts, outline approach, define criteria

Phase 3 Code: Implement iteratively, verify each step, handle edges

Phase 4 Commit: Descriptive messages, logical groupings, clean history

Core Skills

• moai-foundation-claude: This authoring kit
• moai-foundation-core: SPEC system and workflows
• moai-foundation-philosopher: Strategic thinking

Essential Sub-agents

• spec-builder: EARS specifications
• manager-ddd: DDD execution
• expert-security: Security analysis
• expert-backend: API development
• expert-frontend: UI implementation

Sandboxing

• Filesystem: Write restricted to cwd
• Network: Domain allowlists via proxy
• OS-level: bubblewrap (Linux), Seatbelt (macOS)

Dev Containers

• Security-hardened with firewall
• Whitelisted outbound only
• --dangerously-skip-permissions for trusted only

Headless Safety

• Always use --allowedTools in CI/CD
• Validate inputs before passing to Claude
• Handle errors with exit codes
