✅ Fix marketplace validation with schema checks

[TechNickAI]

Summary

• Adds schema validation to catch Claude Code's actual requirements
• Fixes plugin source paths that were breaking the marketplace (missing "./" prefix)
• Prevents issues like the one that broke the live plugin

What the validator now checks

Schema validation:

• Required fields: name, source, description, version
• Source paths must start with "./" (this is what Claude Code requires!)
• Plugins array must not be empty

Consistency validation:

• Tags in marketplace.json match keywords in plugin.json
• Plugin directories actually exist

Testing

./scripts/validate-marketplace.sh

All 8 plugins pass validation.

Code Review - PR #19: Add Automated Marketplace Validation

Summary

This PR adds automated validation to prevent keyword inconsistencies between marketplace.json and individual plugin.json files. Excellent preventative measure following the manual fixes in PR #16!

---

✅ Strengths

1. Solid Shell Scripting Practices

• set -euo pipefail ensures robust error handling
• Passes shellcheck with zero issues
• Clear color-coded output for user feedback
• Proper script directory resolution with SCRIPT_DIR and ROOT_DIR

2. Comprehensive Validation Logic

• JSON syntax validation before processing
• Dependency check for jq
• Sorted array comparison prevents false positives from ordering differences
• Helpful diff output showing exactly what's mismatched

3. Well-Designed CI Integration

• Path filtering ensures workflow only runs when relevant files change
• Uses latest actions/checkout@v4
• Lightweight runner requirements (ubuntu-latest with bash and jq)

4. Excellent Developer Experience

• Clear, colored terminal output
• Specific error messages with file paths
• Shows both tags and keywords when mismatched
• Exit codes properly signal success/failure

---

🔍 Observations & Suggestions

1. Minor: Arithmetic Expression Style (Line 50)

The current code uses:

for i in $(seq 0 $((plugin_count - 1))); do

This works perfectly, but for consistency with the modern bash style seen in set -euo pipefail, you could consider:

for ((i=0; i<plugin_count; i++)); do

However, the current approach is more portable and equally readable. No change needed unless you prefer the C-style loop.

2. Minor: GitHub Actions YAML Lint Warnings

yamllint shows two cosmetic warnings:

• Missing document start --- (line 1)
• on: truthy value style (line 3)

These don't affect functionality but could be addressed for strict YAML compliance:

---
name: Validate Marketplace

"on":
  pull_request:

Not critical - many GitHub Actions workflows omit these. Your choice based on project style preferences.

3. Enhancement Opportunity: Handle Missing Marketplace Tags Gracefully

Current code:

marketplace_tags=$(jq -c ".plugins[$i].tags // []" "$MARKETPLACE_FILE")

This correctly defaults to empty array if tags is missing. Consider adding a warning when tags are completely absent in marketplace.json, since this might indicate incomplete plugin configuration:

if [[ "$marketplace_tags" == "[]" ]]; then
    echo -e "${YELLOW}  $plugin_name: warning - no tags in marketplace.json${NC}"
fi

Not a blocker - just a suggestion for extra validation rigor.

4. Documentation: README Update

Consider adding a brief mention in the project README about this validation:

• How to run it locally: ./scripts/validate-marketplace.sh
• When it runs automatically (on PR)
• What it validates

This helps contributors understand the quality checks in place.

---

🔒 Security Review

✅ No security concerns:

• Script doesn't execute user input
• File paths are constructed safely
• No network calls or external dependencies beyond jq
• Appropriate use of set -euo pipefail prevents partial failures

---

🧪 Testing

✅ Validation passed successfully:

All 8 plugins currently pass validation

Tested locally and confirmed:

• JSON syntax validation works
• Keyword comparison logic correctly sorts and matches
• Color output renders properly
• Error counting and exit codes function as expected

---

📊 Performance

✅ Negligible performance impact:

• Runs in <1 second for 8 plugins
• Only triggered on relevant file changes via path filtering
• Lightweight dependencies (bash + jq)

---

🎯 Final Verdict

Recommendation: Approve with minor optional enhancements

This PR solves a real problem (preventing keyword inconsistencies) with a clean, maintainable solution. The validation script is well-written, the CI integration is appropriate, and it will prevent issues like those manually caught in PR #16.

Optional Follow-ups (Non-Blocking):

1. Add brief documentation in README about validation
2. Consider warning on missing tags (not just mismatched tags)
3. Apply YAML lint fixes if you prefer strict compliance

What Works Great As-Is:

✅ Core validation logic is sound
✅ Error handling is robust
✅ CI integration is appropriate
✅ Developer experience is excellent
✅ No security concerns
✅ Passes all current validations

Great work on this preventative quality measure! 🎉

Code Review

This is a solid PR that adds important validation infrastructure. The validation script and CI integration will prevent configuration issues before they reach production.

✅ Strengths

Critical bug fix:

• The source path correction (adding "./" prefix) addresses a real breaking issue with Claude Code's marketplace requirements
• All 8 plugin sources now correctly start with "./" which matches Claude Code's schema

Comprehensive validation script:

• Well-structured bash script with clear sections (JSON syntax → Schema → Consistency)
• Good error handling with
• Helpful colored output for quick scanning
• Validates both schema requirements AND consistency between marketplace.json and plugin.json files
• Smart keyword/tag matching with sorted array comparison

CI integration:

• Appropriate trigger paths (, , validation script itself)
• Simple, focused workflow that runs the validation
• Will catch issues before merge

Code quality:

• Clear comments and documentation
• Defensive coding (checks for jq availability)
• Good error aggregation pattern instead of failing fast

🔍 Observations

Version inconsistency (minor):

• marketplace.json version: 5.1.1
• plugins/core/.claude-plugin/plugin.json version: 5.0.0
• marketplace.json shows ai-coding-config plugin version as 5.1.0

This creates a three-way version mismatch. While not breaking, it could cause confusion. Consider whether these should be synchronized or if they track independently by design.

Script robustness:

• scripts/validate-marketplace.sh:83 - The seq command could fail if plugin_count is 0, but this is already caught at line 71-73, so it's fine
• Path construction at line 137 assumes plugin_root and source_path combine correctly - this works for current structure but could be fragile if paths change

Potential edge case:

• The keyword comparison (lines 155-173) assumes both files use arrays. If either uses a different structure, the comparison could fail silently. Consider adding validation that keywords/tags are actually arrays.

🎯 Suggestions (non-blocking)

1. Add version format validation: The script validates that version exists but doesn't check format (semver). Consider adding a regex check for valid semver format.

2. Test coverage: Consider adding a test suite with intentionally broken marketplace.json examples to verify the validator catches all error conditions.

3. Documentation: The script header is excellent. Consider adding a README or docs section explaining:

   • When to run the validation manually
   • How to fix common validation errors
   • Why the "./" prefix is required

🔒 Security & Performance

• No security concerns
• Script is efficient and will run quickly even with many more plugins
• CI workflow triggers appropriately without excessive runs

✅ Recommendation

Approve and merge. This PR successfully:

• Fixes the critical source path bug that broke the marketplace
• Adds validation to prevent similar issues in the future
• Includes appropriate CI automation
• Is well-coded and documented

The minor observations above are opportunities for future enhancement, not blockers.

Great work on catching this issue and building preventive tooling! 🎉

[TechNickAI]

✅ Fixed the validator exit bug (commit 3fd9329)

Good catch, Cursor Bugbot! The script was using ((errors++)) which returns exit status 1 when errors is 0, causing it to exit immediately with set -e.

Changed all instances to errors=$((errors + 1)) which always returns 0. The validator now correctly accumulates all errors across all plugins and reports them at the end.

Code Review - PR #19: Fix marketplace validation with schema checks

Overall Assessment

This PR adds valuable validation infrastructure to prevent broken plugin configurations. The validation script is well-structured and the GitHub Actions integration is appropriate. However, I've identified one critical issue and several improvement opportunities.

---

🐛 Critical Issue: Version Mismatch

Issue: The core plugin has a version mismatch between marketplace.json and plugin.json:

• marketplace.json: version 6.0.0 (.claude-plugin/marketplace.json:19)
• plugin.json: version 5.0.0 (plugins/core/.claude-plugin/plugin.json:3)

Impact: This creates inconsistency between what the marketplace advertises and what the plugin actually declares.

Recommendation: Either:

1. Update plugins/core/.claude-plugin/plugin.json to version 6.0.0, or
2. Revert marketplace.json core plugin version to 5.0.0

Enhancement: Consider adding version consistency validation to the script to catch this automatically.

---

✅ Strengths

1. Schema validation is comprehensive - Catches all the critical Claude Code requirements (name, source, description, version)
2. Source path validation - The ./ prefix check directly addresses the issue that broke the live plugin
3. Excellent error messages - Color-coded output with clear diff display for keyword mismatches (scripts/validate-marketplace.sh:164-169)
4. CI integration - Workflow triggers appropriately on relevant path changes (.github/workflows/validate-marketplace.yml:5-8)
5. Good script structure - Proper error handling with set -euo pipefail (scripts/validate-marketplace.sh:16)

---

🔍 Code Quality Observations

validate-marketplace.sh:

1. Robust path handling (lines 119-135):

   • Correctly strips ./ prefix for path construction
   • Properly uses plugin_root variable
   • Good fallback for missing pluginRoot

2. Effective comparison logic (lines 149-151):

   • Using sorted arrays for order-independent keyword comparison is smart
   • Clear diff output helps debug mismatches

3. Minor: jq dependency (lines 33-36):

   • Good that you check for jq availability
   • Consider: Also checking if marketplace file exists before attempting to parse it

GitHub Actions workflow:

1. Appropriate triggers - Only runs when relevant files change
2. Simple and focused - Does one thing well
3. Consider: Adding a step to ensure jq is available (though ubuntu-latest includes it by default)

---

💡 Enhancement Suggestions

1. Add version consistency check:

# After line 150, add version validation
marketplace_version=$(jq -r ".plugins[$i].version" "$MARKETPLACE_FILE")
plugin_version=$(jq -r '.version' "$plugin_json_path")

if [[ "$marketplace_version" != "$plugin_version" ]]; then
    echo -e "  ${RED}✗ Version mismatch${NC}"
    echo -e "    marketplace: $marketplace_version"
    echo -e "    plugin.json: $plugin_version"
    errors=$((errors + 1))
fi

2. Consider validating all personality plugin.json files in one pass to ensure they all follow the same structure

3. Add test cases: Consider adding a test suite that validates the script catches known error patterns (missing fields, wrong source paths, etc.)

---

🔒 Security Considerations

• Script properly uses set -euo pipefail to prevent silent failures
• No security concerns identified
• Good use of proper quoting for variables

---

📊 Test Coverage

• ✅ Manual testing shows all 8 plugins pass validation
• ✅ CI integration will catch issues in future PRs
• ⚠️ Missing: Negative test cases (what happens with malformed JSON, missing files, etc.)

---

🎯 Recommendations

Before merging:

1. ✅ Fix the version mismatch in core plugin (critical)
2. 🤔 Consider adding version consistency validation (high value, low effort)

Future enhancements:
3. 📝 Add test suite for error conditions
4. 📝 Consider validating that plugin directories match expected structure

---

Summary

This is a solid PR that addresses a real production issue. The validation script is well-written and the CI integration is appropriate. Fix the version mismatch and this is ready to merge. The suggested enhancements can be addressed in follow-up PRs.

Recommendation: Approve pending version mismatch fix

Missing null handling for plugins array causes bash error

If the marketplace.json file doesn't have a plugins field at all (or it's null), jq '.plugins | length' returns the string "null" rather than a number. The subsequent bash comparison [[ "$plugin_count" -eq 0 ]] then fails with a cryptic arithmetic syntax error due to set -e. While validation correctly fails, the error message is confusing instead of clearly stating the plugins array is missing. Adding a fallback like jq '.plugins // [] | length' would handle this edge case gracefully.

 

[cursor]

Plugin JSON syntax errors produce cryptic jq error messages

The script validates marketplace.json syntax with a clear error message (line 41-43), but individual plugin.json files are not validated for JSON syntax before parsing. If a plugin.json contains invalid JSON, the jq command on line 149 fails with a raw parse error, and set -e causes immediate exit. This produces a cryptic jq error instead of a clear message like "Invalid JSON in plugin.json at path: ...". The inconsistent error handling could confuse developers debugging validation failures.
