fix: preserve Git skill source paths by tridev-tej · Pull Request #157 · rohitg00/skillkit

tridev-tej · 2026-10-14T05:56:04Z

Summary

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

Changes

Preserve Git-relative paths for files and directories. Keep file copies usable after clone cleanup and retain working installs when sources disappear or change kind.

Existing incorrect metadata still needs a forced reinstall.

Testing

469 E2E cases pass. Two core search tests also time out on the previous head.

Walkthrough

The install flow records Git skill paths relative to the cloned repository. Update handling now reports per-skill statuses and supports standalone files and directories. Tests cover installer behavior, source-path round trips across providers, and 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.
Update status and source validation `packages/cli/src/commands/update.ts`	Update processing reports `updated`, `skipped`, and `failed` counts. Local and Git updates validate their sources, support file and directory installs, and save metadata and lock entries.
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

Suggested reviewers: rohitg00

Merge Risk: Moderate · up to ae81d

Standalone Git updates can replace working skills with unusable or external file contents, or lose them when copying fails. Resolve source validation and safe replacement before merging.

A standalone local .md skill can be skipped as local source missing, leaving the installed copy stale. The same behavior exists at the merge base. Recording the filename alone is not a complete fix because updateLocalSkill expects a directory containing SKILL.md.

Validate the resolved Git source before copying.

A persisted traversal or top-level symlink can resolve outside clonePath. The standalone-file path then accepts and copies that file into the installed skill.

Import realpathSync from node:fs, not node:path. Use the resolved source for validation, checksum, and copying.

Reject standalone sources that the skill loader cannot parse.

For a standalone install, isGitSourceValid accepts any regular file. A replacement without YAML frontmatter overwrites the working skill and is reported as updated. parseStandaloneSkill then drops it. Validate the frontmatter before copying.

extractFrontmatter and readFileSync must be imported in update.ts. I did not confirm those imports.

Back up the installed file before the copy in copyGitSkill.

copyGitSkill deletes the installed file before it copies the new version. If copyFileSync then fails, for example with ENOSPC when the new file is larger than the removed one, the working skill is gone and the update reports failure. Copy to a temporary sibling first, then rename it over the target.
