Claude Code Platform Skill
This skill provides comprehensive expertise on using Claude Code effectively.
Skill Directory: ~/.claude/skills/claude-code-platform/
Core Tool Knowledge
File Operations
Read Tool: Read files with file_path (required), optional offset and limit for large files. Returns up to 2000 lines, supports images/PDFs/Jupyter notebooks.
Write Tool: Create files with file_path and content. MUST Read existing files first. Always prefer Edit over Write for existing files.
Edit Tool: Replace text with file_path, old_string, new_string, optional replace_all. String must be unique or use replace_all. MUST Read file first.
Glob Tool: Find files with pattern (e.g., **/*.ts) and optional path. Returns sorted by modification time.
Grep Tool: Search with pattern, optional path, output_mode (content/files_with_matches/count), -i for case-insensitive, -n for line numbers, multiline for cross-line patterns.
Execution
Bash Tool: Execute commands with command (required), description (recommended), timeout (default 120000ms, max 600000ms), run_in_background (for async execution). Always quote paths with spaces. Use && for dependent commands, parallel tool calls for independent commands.
Task Tool: Launch subagents with subagent_type and prompt. Available types: general-purpose, Explore (quick/medium/very thorough), pragmatic-lead, qa, plus custom agents.
Core Patterns
Parallel Execution: Call multiple independent tools in one message for dramatic speedup.
Tool Selection: Specialized tools (Read/Edit/Grep/Glob) > Bash commands for file operations.
Progressive Loading: Glob → Grep → Read (narrow before deep dive).

Quick Reference Examples
Reading multiple files in parallel:
✓ Read file1.ts + Read file2.ts + Read file3.ts (one message)
✗ Read file1.ts → wait → Read file2.ts (sequential)
Finding and searching:
Step 1: Glob **/*.ts
Step 2: Grep "pattern" --type ts --output-mode files_with_matches
Step 3: Read specific matches
Bash best practices:
✓ git add . && git commit -m "msg" && git push (sequential with &&)
✓ cd "/path with spaces/" (quoted paths)
✗ cat file.txt (use Read tool instead)
MCP tool naming: mcp__server-name__function-name
Task tool for deep work: Use Explore agent (thoroughness: quick/medium/very thorough) for codebase exploration.
Haiku vs Sonnet: Haiku 4.5 = routine tasks (2x speed, 1/3 cost), Sonnet 4.5 = complex reasoning.
Key Principles
- Specialized tools > Bash for file operations
- Parallel when independent for speed
- Progressive disclosure - Glob → Grep → Read
- Read before Write/Edit always
- Verify after critical operations
- Clear tool descriptions for user transparency
This Skill Uses Progressive Disclosure
- Level 1 (This file): Core tool knowledge and quick reference
- Level 2 (Reference files): Detailed docs loaded via bash when needed
- Level 3 (On-demand): Specific sections of reference files as required
When you need deeper information, read the appropriate reference file from the skill directory using bash commands shown above.
Version: 2.0 - Updated Oct 16, 2025 for proper progressive disclosure
