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

ParameterTypeRequiredDefaultDescription
--focusstringYes-Keywords to filter file names/content (e.g. "gas", "auth")
--max-filesintNo50Limit output size

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

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