+## Context
+
+Plugin load failures showing only "1 error" with no details about what's wrong.
+
+## Problem
+
+Claude Code's plugin loader doesn't surface specific validation errors. When a plugin fails to load, you see:
+
+```
+viz-platform Plugin · leo-claude-mktplace · ✘ failed to load · 1 error
+```
+
+No indication of WHAT the error is.
+
+## Root Cause
+
+15 command markdown files were missing the required `name:` field in YAML frontmatter:
+
+```yaml
+# WRONG - causes silent load failure
+---
+description: Some description
+---
+
+# CORRECT
+---
+name: command-name
+description: Some description
+---
+```
+
+## Debugging Steps Taken (wasteful)
+
+1. Checked MCP server venvs - OK
+2. Checked symlinks - OK
+3. Checked plugin.json files - OK
+4. Checked hooks.json - OK
+5. Checked run.sh scripts - OK
+6. Finally checked command frontmatter - FOUND IT
+
+## Solution
+
+Add `name:` field to all command files:
+
+```bash
+# Check for missing name fields
+for f in plugins/*/commands/*.md; do
+  grep -q '^name:' "$f" || echo "MISSING: $f"
+done
+```
+
+## Prevention
+
+1. **Validate before commit**: Add pre-commit hook to check all command files have `name:` field
+2. **Template enforcement**: Command file template must include `name:` as first field
+3. **File issue**: Claude Code should show actual validation errors, not just "1 error"
+
+## Time Wasted
+
+Significant token burn debugging every layer when error message should have said:
+"commands/chart.md: missing required 'name' field"
+
+## Filed Issue
+
+GitHub issue template saved to `.scratch/github-issue-plugin-errors.md` for submission to anthropics/claude-code
