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
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
--focus |
string | Yes | - | Keywords to filter file names/content (e.g. "gas", "auth") |
--max-files |
int | No | 50 | Limit output size |
Outputs
RELEVANT_FILES.txt: List of absolute paths to read.- 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
$files = .\skills\08_context_pruner\prune_context.ps1 -Focus "EVM opcode"
# Agent works only with $filesCategories
