Patchloom

What it does

Patchloom provides AI agents with a robust way to edit structured files (JSON, YAML, TOML) and Markdown without corrupting syntax. It replaces fragile text-matching with parser-backed selector edits and reduces LLM round-trips by batching multiple file operations into a single atomic transaction.

Tools

• doc: Edit JSON/YAML/TOML values by selector path while preserving comments and formatting.
• batch: Combine multiple file edits across different files into one tool call.
• tx: Execute complex JSON-based transaction plans with format and validate lifecycle steps.
• md: Perform heading-aware edits to Markdown tables, sections, and bullets.
• patch: Apply unified diffs with stale context detection to handle drift.
• tidy: Normalize whitespace and newlines across text files.
