Skill: OpenCode Apply Reconstituted Diffs

Goal

Apply reconstructed diff patches safely and validate that the workspace is consistent afterward.

Use This Skill When

• You have recovered patches from OpenCode sessions
• The user wants diffs applied to reconstitute lost work
• You need a controlled, auditable application of changes

Do Not Use This Skill When

• The changes already exist in a branch or git history
• The diffs are incomplete or untrusted

Inputs

• Patch files or diff directories
• Target repo root
• Required test or build commands

Steps

1. Create a clean working state (stash or branch as needed).
2. Dry-run each patch with git apply --check.
3. Apply patches in a deterministic order (oldest to newest).
4. Resolve conflicts manually and re-run checks.
5. Run tests or typechecks that cover changed areas.

Output

• A summary of applied patches and any conflicts
• Test results or failure notes
