name: diff description: Use when implementing or debugging code that uses @suaveplan/diff: Zero-dependency RFC 6902 JSON Patch engine with structural diffing, patch application/inversion, linear history manager, sync manager, and rich path utilities.

@suaveplan/diff

Zero-dependency RFC 6902 JSON Patch engine for computing, applying, and inverting structural differences between JSON documents. The diff(a, b) function produces a minimal patch using index-based or LCS array strategies; applyPatch applies it; revertPatch undoes it; and invertPatch creates an inverse patch. A HistoryManager provides undo/redo with configurable depth and branch truncation on new edits. A SyncManager handles optimistic concurrency: apply local changes speculatively, then reconcile when the server responds. RFC 6901 JSON Pointer parsing and formatting is exposed as a standalone path module. Use this package for collaborative editing, undo/redo stacks, change-event streams, and any system where you need to track or transmit the delta between two object states rather than the full state itself.

When to use this skill

• Implementing or debugging code that imports @suaveplan/diff.
• The task touches: see package README.
• You need API guidance for this package's exports.

Quick reference

import { /* see API Reference below */ } from "@suaveplan/diff";

Dependencies

Workspace dependencies: none

Where to read more

This skill is intentionally short. The package's own documentation is the authoritative source — read these in order:

1. packages/foundation/diff/README.md — overview, install, quick-start, module index
2. packages/foundation/diff/src/**/*.md — co-located docs per implementation file (Purpose, Features, Basic + Advanced examples, full API reference, Implementation notes — all packages ship ≥200 words per module)
3. packages/foundation/diff/package.json exports map — every subpath you can import from

When the user asks an API question, read the relevant co-located .md first; do not answer from training-data memory.
