Skill tool fails immediately when invoking code-review plugin (Execute skill error, ~24ms)

[expsg-jiacheng]

Describe the bug

When code-review@claude-code-plugins is configured as a plugin, the plugin installs successfully and appears correctly in the skill list, but the Skill tool call fails immediately (~24ms) with a generic error. Claude then falls back to performing the review inline without the plugin.

Environment

• Claude Code version: 2.1.90
• claude-code-action: anthropics/claude-code-action@v1 (SHA: 58dbe8ed6879f0d3b02ac295b20d5fdfe7733e0c)
• Session ID: b27886c8-78cf-4530-aafe-930f542ef645
• Trigger: issue_comment

Steps to reproduce

1. Configure the workflow with code-review@claude-code-plugins plugin (see workflow below).
2. Trigger via PR comment (@claude please review this PR).
3. Plugin installs and is listed in skills correctly.
4. Claude invokes Skill tool with { "skill": "code-review:code-review", "args": "--comment" }.
5. Tool returns is_error: true after ~24ms.

What happens

From the session log (show_full_output: true):

✔ Successfully installed plugin: code-review@claude-code-plugins (scope: user)
...
"skills": ["code-review:code-review", ...]   ← plugin registered correctly
...
# Claude invokes Skill tool:
{ "name": "Skill", "input": { "skill": "code-review:code-review", "args": "--comment" } }

# Immediate failure (~24ms later):
{ "type": "tool_result", "content": "Execute skill: code-review:code-review", "is_error": true }
"tool_use_result": "Error: Execute skill: code-review:code-review"

The error message is just the execution command echoed back with no stack trace or detail, suggesting an unhandled exception in the skill execution layer.

Expected behavior

The code-review:code-review skill executes and performs the review using the plugin's logic.

Actual behavior

Skill tool fails immediately. Claude falls back to performing an inline review without the plugin.

      If asked to review code or a pull request, you MUST use `/code-review:code-review --comment`.

Notes

• The rate_limit_event (overageStatus: rejected) fires at the same timestamp but is unrelated — status: allowed confirms the request went through.
• Related but different issue: code-review plugin completes review but produces empty result — no PR comment posted #1087 (plugin completes but posts no comment — different failure mode).
• Plugin path on runner: /home/runner/.claude/plugins/marketplaces/claude-code-plugins/plugins/code-review

Having the same issue with invoking plugin skill from custom market place, marketplace registered correctly:

Installing plugin: test-plugin-from-remote-marketplace-invocation@shared-workflows
Installing plugin "test-plugin-from-remote-marketplace-invocation@shared-workflows"...
✔ Successfully installed plugin: test-plugin-from-remote-marketplace-invocation@shared-workflows (scope: user)
✓ Successfully installed: test-plugin-from-remote-marketplace-invocation@shared-workflows

but then skill invocation fails:
"thinking": "The skill executed but returned an error. It appears the skill test-plugin-from-remote-marketplace-invocation:test-plugin-from-remote-marketplace-invocation encountered an issue when invoked....

Locally skill works without issue when invoked from plugin
