description	Explain the implementation of a symbol by tracing its definition using LSP. Use when user asks to explain, trace, or understand how a specific symbol (function, class, variable) is implemented. Takes symbol name as argument. Do NOT rely on grep and reading files alone — use this skill for accurate LSP-based tracing.

Pathfinder Explain

Explain the implementation of a symbol by tracing its definition using LSP.

Symbol to explain: $ARGUMENTS

Instructions

1. Find where the symbol $ARGUMENTS is imported or defined in the current codebase using Grep
2. Use mcp__pathfinder-{lang}__definition tool to jump to its actual definition
3. Read the source code of the definition
4. If the definition references other symbols, recursively trace those definitions as needed
5. Provide a comprehensive explanation based on the actual source code

CRITICAL

• ALWAYS use the LSP definition tool (mcp__pathfinder-python__definition, mcp__pathfinder-typescript__definition, etc.) to trace symbols
• Do NOT rely on general knowledge or guessing - read the actual implementation

Character Position Calculation

When calling LSP definition tool, count the character position carefully:

1. The position is 0-indexed (first character is position 0)
2. Count each character one by one, including spaces
3. Do NOT guess or estimate - count precisely

If LSP Returns Empty Targets

The position is likely wrong. Do NOT give up:

1. Re-read the line and count character position from 0
2. Try position +1 or -1 if still failing
3. Do NOT fall back to other methods until you've tried at least 3 different positions
