SKILL-008: Context Window Pruner

Overview

Large repos flood the agent's context window with noise. This skill generates a RELEVANT_FILES.txt list by aggressively pruning irrelevant directories and searching for files related to a specific "Focus".

Trigger Phrases

• focus on <topic>
• find relevant files for <task>
• prune context

Inputs

Outputs

1. RELEVANT_FILES.txt: List of absolute paths to read.
2. Console output summarizing token savings (estimated).

Safety Checks

• Always respects .gitignore.
• Never includes binary files.
• Caps output to avoid context overflow.

Implementation

See prune_context.ps1.

Integration

Copy$files = .\skills\08_context_pruner\prune_context.ps1 -Focus "EVM opcode"
# Agent works only with $files
