# Diff Project Show what changed in dotforge since the last synchronization of the current project. ## Step 1: Identify project baseline 1. Read `$DOTFORGE_DIR/registry/projects.yml` 2. Find the current project by `path` (compare with `$PWD`) 3. Get `dotforge_version` and `last_sync` 4. If no `dotforge_version` is registered (null), report: ``` Project not synced — no baseline to compare against. Run /forge sync to establish baseline. ``` And stop. ## Step 2: Verify local manifest If `.claude/.forge-manifest.json` exists in the current project: 1. Read it and get the version and file hashes 2. For each file in the manifest, calculate `shasum -a 256 <file> | cut -d' ' -f1` 3. Compare against the registered hash 4. Report locally modified files (hash differs) and deleted files 5. Use the manifest version as baseline (more precise than the registry) If manifest does NOT exist, continue to Step 3 using git log. ## Step 3: Detect changes in dotforge Run in `$DOTFORGE_DIR/`: ```bash git log --oneline v<version>..HEAD -- template/ stacks/ ``` Where `<version>` is the tag corresponding to the project's `dotforge_version`. If the tag does not exist, use `last_sync` as reference: ```bash git log --oneline --since="<last_sync>" -- template/ stacks/ ``` If there are no relevant commits, report: ``` dotforge has no changes in template/stacks since v<version>. Project is up to date. ``` ## Step 4: Show change summary For each modified file in template/ or relev
