Intentumdiff Diff Expectations
The behavioral oracle for the IntentumDiff engine — a scenario catalogue that says, per diff scenario, exactly what the engine SHOULD produce (which changes, with which labels, and which change_groups are surfaced vs suppressed, and why). Use this whenever you implement, fix, port, or review engine behavior for a language/scenario, when you need the expected result for a test (Python acceptance OR Rust #[cfg(test)]), or when deciding "is this diff output correct?". This catalogue — not the Python `analysis/*` implementation — is the source of truth: Python is no longer the oracle. Every scenario here must be enforced by BOTH a Python acceptance assertion (via `SemanticDiffer`) and a Rust unit test. Read intentumdiff-language-profiles / -engine for the mechanism, and intentumdiff-dev-loop for the migrate-to-Rust workflow this oracle drives.

From the source SKILL.md
Why this exists. IntentumDiff's engine is moving from Python into the Rust core; the Python analysis/* implementation is legacy being retired, so it can no longer be the reference for "correct." The reference is now explicit expectations: for a given input, the exact review output the engine should produce. This catalogue is that reference. It is enforced at two layers that must agree:
What this skill does
Intentumdiff Diff Expectations is a community-contributed Claude Code skill in the engineering-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/intentumdiff-diff-expectations/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The Intentumdiff Diff Expectations Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 196,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Intentumdiff Diff Expectations skill?
Use Intentumdiff Diff Expectations when your Claude Code task falls under the Engineering category — specifically in the engineering misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Intentumdiff Diff Expectations" or describe the task and let Claude pick). Browse related skills at
/category/engineering/.
What is a Claude Code skill and how does the Intentumdiff Diff Expectations skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Intentumdiff Diff Expectations is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category. Learn more at
