What does this PR do?

Fixes a bug in collectResources() within the Claude plugin converter that causes complex plugins (like microsoft/skills deep-wiki) to install as empty shells — the extension reports success but no commands, skills, or agents are actually available.

Root cause: When the marketplace config specifies resource paths like ["./commands/"] pointing to a directory at the plugin root with the same name as the destination folder, collectResources() previously skipped the copy, assuming the content was already in place from the earlier copyDirectory step. However, step 6.1 in convertClaudePluginPackage deletes the destination folder before calling collectResources, leaving it permanently empty.

The existing test suite already documented this with a workaround comment (line 392): "renamed to src-agents to avoid skip-logic bug".

Fix:

Directory paths (e.g., ./commands/): Instead of skipping when the directory name matches the destination folder, copy contents directly into the destination (avoiding the double-nesting the original skip was trying to prevent).
File paths (e.g., ./agents/wiki-architect.md): Strip the leading folder segment that matches the destination name, then copy to the correct location.

How did you verify your code works?

Added a new test case should collect resources from same-name root directories that replicates the exact deep-wiki plugin structure (commands/, skills/, and agents/ at plugin root, referenced via ["./commands/"], ["./skills/"], ["./agents/wiki-architect.md"])
All 18 tests in claude-converter.test.ts pass
Pre-commit hooks (prettier + eslint) pass

Screenshots / recordings

N/A — no user-facing UI change. This is an internal file-copy logic fix.

…enLM#4452) When marketplace config specifies resource paths like `["./commands/"]` that point to a directory at the plugin root with the same name as the destination folder, collectResources() previously skipped the copy — assuming the content was already in place from the initial copyDirectory step. However, step 6.1 deletes the destination folder before calling collectResources, leaving it empty. Fix: instead of skipping, copy the directory contents directly into the destination (avoiding the double-nesting that the original skip intended to prevent). For individual file paths (e.g., `./agents/wiki-architect.md`), strip the leading folder segment and copy to the correct destination. This fixes installation of complex Claude plugins like microsoft/skills deep-wiki that specify commands/, skills/, and agents/ at the plugin root. Fixes QwenLM#4452

Local maintainer validation — all PR-relevant gates green ✅

Reviewed at head b89a94730 (against base 0cb9ff0a2) in a dedicated tmux session (pr4459, 8 windows) under git worktree /.qwen/tmp/review-pr-4459. The PR has a single author commit — small, focused fix.

Environment

macOS 26.4.1 (Darwin 25.4.0 arm64), Node 22.17.0, npm 11.8.0
Fresh npm ci (1453 packages)
Repo version 0.15.11

Results

Stage	Command	Result
Install	`npm ci`	✅ exit 0
Build	`npm run build`	✅ exit 0 (only pre-existing `curly` warnings in vscode-ide-companion)
Typecheck	`npm run typecheck`	✅ exit 0 across all 5 workspaces
Lint	`npm run lint`	✅ exit 0
PR-specific tests: `claude-converter.test.ts`	`cd packages/core && npx vitest run src/extension/claude-converter.test.ts`	✅ 18/18 (includes the new `should collect resources from same-name root directories` scenario that reproduces #4452's deep-wiki plugin structure)
Adjacency regression: all `packages/core/src/extension/` tests	`cd packages/core && npx vitest run src/extension/`	✅ 11 files / 217 tests / 0 failures in 17s
Full `packages/core` suite	`cd packages/core && npx vitest run`	⚠️ 2 files / 3 tests failed — all 3 pre-existing / environmental, none caused by this PR (see Triage)
Full `packages/cli` suite	`cd packages/cli && npx vitest run`	⚠️ 1 file / 1 test failed — same pre-existing flake that failed on both macOS and Ubuntu CI (see Triage)

Triage of all 4 local failures (NOT caused by PR 4459)

File	Fails	Cause	Verified
`packages/core/src/skills/skill-manager.test.ts`	2	Test fixture's bundled-path detection uses `!pathStr.includes('.qwen')`; our worktree lives under `.qwen/tmp/` so the `.qwen` segment makes the mock misclassify the bundled dir	Reproduces on all `.qwen/tmp/` worktrees (#4314, #4345, #4354, #4386, #4390)
`packages/core/src/core/anthropicContentGenerator/anthropicContentGenerator.test.ts`	1	Claude Code UA injection (`claude-cli/1.2.3` overrides `QwenCode/1.2.3`)	Reproduces on `qwen-code-x3/main` and all prior PR validations
`packages/cli/src/ui/AppContainer.test.tsx`	1	`does not remeasure footer height for sticky todo status-only updates` — expected spy called 1 time, got 2 times. React terminal-height measurement test with test-isolation issues (`Config was already initialized` error).	Same failure on both macOS and Ubuntu GitHub Actions runners; also reproduced on Windows CI in some runs. Classic React test flake.

CI failure analysis

The PR's GitHub Actions run (26327068673) shows:

Runner	Core Tests	CLI Tests	Status
macOS	✅ 340 passed, 9273/9276	❌ 1 failed (`AppContainer` flake)	FAILURE
Ubuntu	✅ 340 passed, 9273/9276	❌ 1 failed (`AppContainer` flake)	FAILURE
Windows	✅ 340 passed, 9273/9276	✅ all passed	SUCCESS

All three CI runners pass core tests (where this PR's change lives). The macOS and Ubuntu failures are exclusively in the CLI's AppContainer.test.tsx — a React terminal-layout test with no relationship to the extension/claude-converter module. Windows passed cleanly. This is a pre-existing flake unrelated to #4459.

Fix analysis

The fix in packages/core/src/extension/claude-converter.ts addresses two paths in collectResources():

1. Directory paths (e.g., marketplace config specifies "./commands/" and plugin root has commands/ dir):

Before (bug): The directory was skipped entirely (continue) — the old code assumed its contents were already in place from the earlier copyDirectory step, but step 6.1 in convertClaudePluginPackage deletes the destination folder before calling collectResources, leaving it permanently empty.

After (fix): When the directory name matches the destination folder and sits at the plugin root, copy contents directly into destDir rather than creating a nested subdirectory or skipping. This correctly places the resources.

2. File paths (e.g., marketplace config specifies "./agents/wiki-architect.md" and plugin root has agents/wiki-architect.md):

Before (bug): The file was skipped when segments[0] === destFolderName (same assumption).

After (fix): Strip the leading segment that matches the destination folder name (e.g., agents/wiki-architect.md → wiki-architect.md), then copy to the correct location under destDir. Also adds defensive fs.mkdirSync for the file's parent directory.

The logic is minimal and correct — it removes the two continue skip branches and replaces them with proper destination resolution, plus a small defensive mkdir in the file path.

Notable: The existing test at line 392 still uses src-agents as a workaround for the bug this PR fixes. That's a test fixture naming choice — the new dedicated should collect resources from same-name root directories test exercises the real fix with same-name paths. The workaround is not a regression; it could be updated in a follow-up cleanup.

Reviewer recommendation

Safe to merge. This is a textbook bug fix:

Diff: +125 / −26 across 2 files (source + test), single commit
Root cause clearly identified: collectResources incorrectly skipped resources when the source directory/file shared a name with the destination folder
Fix: replace continue (skip) with correct destination-path resolution
Test coverage: new scenario replicates the exact deep-wiki plugin structure from Qwen Code doesn't install Microsoft Claude Code plugin properly #4452 — same-name directories for commands, skills, and agents
All PR-relevant tests pass locally (18/18 claude-converter, 217/217 extension suite)
Core CI fully green on all 3 platforms (macOS/Ubuntu/Windows) where it matters
The single CLI failure on CI (AppContainer.test.tsx) is a pre-existing React layout flake with no connection to this PR's change surface
The 3 pre-existing local core failures (skill-manager, anthropicContentGenerator) have been documented across 6 prior PR validations

[Suggestion] The function's JSDoc (lines 550-554) is now outdated. It still says "If a resource is already in the destination folder, it will be skipped", but this fix reverses that behavior — same-name root directory resources are now actively copied/flattened into the destination folder, not skipped. Consider updating the JSDoc to reflect the new behavior.
