sc-diff
Capabilities
- Compare two files or two folders (exactly one of each per request)
- Auto semantic diff for .cs/.vb with line fallback for non-.NET files
- JSON-first output for AI consumption
- Optional HTML report per pair
- Git/PR-based comparisons via sc-git-diff
- Smart batching for large diff sets
Agent Delegation
| Operation | Agent | Returns |
|-----------|-------|---------|
| File/folder diff | sc-diff | JSON: results[], counts, warnings |
| Git/PR diff | sc-git-diff | JSON: results[], refs, counts |
Invoke agents via Agent Runner using .claude/agents/registry.yaml.
Parameters
files: string (comma-delimited list of 2 file paths)folders: string (comma-delimited list of 2 folder paths)html: boolean (default false)mode:auto(default),roslyn,lineignore_whitespace: boolean (default false)context_lines: number (optional, default 3)text_output: string|bool (optional; true writes.sc/roslyn-diff/temp/diff-#.txt)git_output: string|bool (optional; true writes.sc/roslyn-diff/temp/diff-#.patch)allow_large: boolean (default false)files_per_agent: number (default 10)max_pairs: number (default 100)git_pr: string (PR URL or PR number)
Behavior
- Validate exactly one of
filesorfolders. - Resolve inputs into file pairs.
- If pair count >
max_pairsandallow_largeis false, stop with a warning. - If pair count >
files_per_agent, split into batches and spawn sub-agents. - Aggregate results: include non-identical diffs and counts.
Caching
- Cache Azure DevOps org/project/repo in
.sc/roslyn-diff/settings.json. - Store defaults like
files_per_agentwhen set explicitly.
Output Contract
- Always return fenced JSON with a discriminated union:
success: true|false. success: trueincludes aggregated counts and per-pair roslyn-diff JSON outputs.

Set up a repo-local just task runner with a root Justfile, optional .just/ helper scripts, and curated help, build, fmt, lint, test, and ci recipes. Use when a repo needs just, a Justfile, .just helpers, or when the user mentions task automation, "just build", "just lint", "just fmt", or dropping in a just system.
