name: Paste Sanitizer description: Convert mixed terminal output and instructions into safe, paste-ready command blocks.

SKILL-023: Paste Sanitizer

Purpose

Convert “chatty” instructions, shell prompts, and terminal output into a safe, paste-ready command block that satisfies the Pre-Action Guard (Skill-018).

This skill ensures that unintended text like PS C:\, Everything up-to-date, or error dumps are never pasted into a live terminal.

Goal

Enforce Command-Only output for all runnable steps.

Algorithm

1. Identify lines that match "likely command" patterns:
   • Starts with git, dotnet, npm, python, cd, mkdir, $env:, etc.
2. Identify and Drop lines that match "likely output" or "prompt" patterns:
   • Starts with PS, Contains Everything up-to-date, At line:, CategoryInfo:, error:, warning:, etc.
3. Comment Out (optional) unknown lines with # instead of deleting, to preserve context safely within a script.
4. Wrap the cleaned commands in a labeled block: ## COPY/PASTE COMMANDS.

Trigger Phrases

• sanitize commands
• clean terminal output
• make paste-ready

Expected Output Format

Copy## COPY/PASTE COMMANDS
```powershell
git add .
git commit -m "fix"
git push

Copy
## Safety Constraints
- Only copy blocks labeled **COPY/PASTE COMMANDS**.
- Never copy blocks labeled **Expected Output**.
- If a line inside the command block does not start with a tool or verb, the sanitizer has failed.

## Implementation
See `scripts/paste_sanitizer.ps1`.
