Summary

Git updates could skip skills or copy a same-named decoy.

Changes

I retain discovered paths relative to the selected source and preserve existing copy/symlink and agent handling.

Existing incorrect installs still need explicit reinstallation with --force.

Testing

441 E2E cases pass, including 47 source path scenarios.

Summary by CodeRabbit

  • Bug Fixes
    • Git-installed skills now retain their source subdirectory, helping updates find the correct skill when it’s nested in a repository.
  • Documentation
    • Added guidance for updating existing Git installs. Installs with incorrect source metadata may require a forced reinstall; renamed or moved source directories are not supported.

📝 Walkthrough

The install flow now records Git skill paths relative to the cloned repository. Added tests cover installer behavior and source-path round trips across Git providers, alongside guidance for existing installs with incorrect metadata.

Changes: Git install and update behavior

Layer / File(s) Summary
Per-agent installation pipeline
packages/cli/src/commands/install.ts, packages/cli/src/__tests__/commands.test.ts
performInstall delegates per-agent installation to helpers for target preparation, source containment, content installation, metadata, and dependencies. Characterization tests cover copy and symlink behavior, skips, failures, and dependency installation.
Source-path metadata and round-trip coverage
packages/cli/src/commands/install.ts, e2e/core-commands.e2e.test.ts, packages/cli/README.md
Git providers store the skill path relative to the clone path as metadata. E2E tests cover provider updates, legacy metadata, forced reinstall, and local and well-known HTTP sources. The README describes reinstall guidance for incorrect metadata.

Change: Bug fix

Merge Risk: 🔵 Low · up to 4ce7f

Updates to nested standalone Git skills can be skipped. The affected workflow is narrow, and users can reinstall; fix the source-path handling before merge if this workflow is supported.

Preserve standalone Git file paths during updates.

getSkillSubpath stores only the skill name for standalone Git files. The update branch then resolves that name from the clone root and requires SKILL.md below it. A nested standalone file therefore skips the update.

Store the Git-relative file path. Detect an existing file before calling statSync, retain the current missing-source skip, and copy file sources directly.
