Code Review Summary

I've reviewed this PR which contains two commits:

1. Schema version bump (dfbac38) - Updates MCP schema from 2025-10-17 to 2025-12-11
2. Documentation updates (c433a27) - Aligns documentation with agent-skills-spec format

✅ Strengths

Schema Update:

• Clean, focused change updating the $schema URL in packages/mcp/server.json:2
• Follows semantic versioning convention for schema dates
• Commit message follows conventional commits format: chore: bump mcp schema version

Documentation Updates:

• Comprehensive documentation alignment across 7 files
• Detailed commit message explaining all changes
• Fixes inconsistent directory structure diagrams
• Updates plugin discovery mechanism references from "via AGENTS.md" to "via marketplace.json"
• Properly scoped as docs: type commit

🔍 Observations

Missing PR Description:
The PR has no description explaining:

• Why the schema version was bumped (breaking changes? new features?)
• Whether this is a breaking change for users
• If any action is required from users or downstream consumers
• Link to MCP schema changelog or release notes

Commit Message Scope:
The first commit (chore: bump mcp schema version) could be more specific with scope: chore(mcp): bump schema version per git-workflow.md:69 which states: "Use package name for package-specific changes: (mcp), (ai-sdk-plugin)"

Schema Verification:
I cannot verify the new schema URL is valid due to network restrictions, but the pattern follows the expected format: https://static.modelcontextprotocol.io/schemas/YYYY-MM-DD/server.schema.json

📋 Recommendations

Before Merging:

1. Add PR description explaining:

   • Reason for schema version bump
   • Whether this introduces breaking changes
   • Link to MCP schema changelog
   • Any migration steps needed

2. Consider scope in first commit: While not blocking, adding (mcp) scope would improve consistency: chore(mcp): bump schema version

✨ Overall Assessment

The changes are technically sound and follow project conventions well. The documentation updates are thorough and well-explained. The main improvement would be adding context via a PR description to help reviewers and future maintainers understand the motivation and impact of the schema version change.

Status: ✅ Approved with minor suggestions (non-blocking)

🐛 Pre-existing Bug Found (Not Introduced by This PR)

Location: docs/MARKETPLACE.md:20

The Claude Code installation example is missing the required --claude flag:

# ❌ Current (line 20) - will fail with error
curl -fsSL https://raw.githubusercontent.com/youdotcom-oss/dx-toolkit/main/scripts/install-plugin.sh | bash -s teams-anthropic-integration

# ✅ Should be
curl -fsSL https://raw.githubusercontent.com/youdotcom-oss/dx-toolkit/main/scripts/install-plugin.sh | bash -s teams-anthropic-integration --claude

Why this is a bug: The install script validates inputs at lines 77-78 and will error if no mode flag is provided:

if [ -z "$PLUGIN_NAME" ] || [ -z "$INSTALL_MODE" ]; then
  error "Usage: curl -fsSL ... | bash -s <plugin-name> --claude|--cursor|--agents

Note: This bug exists on main branch and was NOT introduced by this PR. However, since it affects user experience, it should be fixed in a follow-up PR.

⚠️ Security & Best Practices

1. Sparse Checkout Security (scripts/install-plugin.sh:115-121)

cd "$TEMP_DIR"
git init -q
git remote add origin "https://github.com/$REPO.git"
git config core.sparseCheckout true
echo "plugins/$PLUGIN_NAME/" >> .git/info/sparse-checkout
git pull -q --depth=1 origin "$BRANCH"

✅ Good: Uses sparse checkout to download only needed files
✅ Good: Uses --depth=1 to limit history
✅ Good: Validates $PLUGIN_NAME format at lines 104-107 to prevent path traversal

2. jq Dependency Handling (scripts/install-plugin.sh:175-183)

if command -v jq &> /dev/null; then
  jq --arg name "$MARKETPLACE_NAME" --arg repo "$MARKETPLACE_REPO" '...'
else
  warning "jq not found - please manually add marketplace to .claude/settings.json"

✅ Good: Gracefully degrades when jq not available
✅ Good: Provides clear manual instructions as fallback

3. Cleanup Trap (scripts/install-plugin.sh:39-47)

TEMP_DIR=""
cleanup() {
  if [ -n "$TEMP_DIR" ] && [ -d "$TEMP_DIR" ]; then
    info "Cleaning up temporary files..."
    rm -rf "$TEMP_DIR"
  fi
}
trap cleanup EXIT

✅ Good: Ensures temp files are cleaned up even on errors

📋 Code Quality Observations

1. Input Validation

• ✅ Plugin name format validation (lines 104-107)
• ✅ Mode flag validation (lines 77-78)
• ✅ Plugin existence check (lines 124-128)
• ✅ Skills directory validation (lines 131-134)

2. User Experience

• ✅ Colored output for success/error/warning/info
• ✅ Clear error messages with examples
• ✅ Next steps guidance after installation
• ✅ Helpful usage examples in help text

3. agent-skills-spec Compliance

• ✅ Validates skills/ directory exists
• ✅ Copies entire plugin directory (not just AGENTS.md)
• ✅ Works with SKILL.md format (verified in plugins/teams-anthropic-integration/skills/SKILL.md)

🔍 Additional Review Points

1. MCP Schema Version

• New schema: 2025-12-11
• ✅ URL pattern correct: https://static.modelcontextprotocol.io/schemas/2025-12-11/server.schema.json
• ⚠️ Missing PR Description: No explanation of what changed in the schema or if this is a breaking change

2. Documentation References

• ✅ AGENTS.md lines 57-62 correctly show agent-skills-spec format
• ✅ README.md lines 139-143 updated to reflect new structure
• ✅ All plugin READMEs updated with correct install commands

3. Commit Message Quality

• ✅ Follows conventional commits format
• ✅ Detailed descriptions in commit bodies
• ⚠️ First commit could use scope: chore(mcp): bump schema version

🎯 Recommendations

Non-blocking Improvements:

1. Add PR description explaining:

   • Reason for MCP schema version bump
   • Whether this is a breaking change
   • Link to MCP schema changelog/release notes
   • Any user migration steps needed

2. Consider adding scope to first commit: While not strictly required, chore(mcp): bump schema version would be more consistent with project guidelines (see .claude/rules/git-workflow.md:69)

3. Fix pre-existing MARKETPLACE.md bug in follow-up PR: Add missing --claude flag at line 20 (see bug section above)

✨ Overall Assessment

Code Quality: Excellent - The install script refactoring is well-executed with proper error handling, validation, and user experience considerations.

Documentation: Very good - Comprehensive updates across 7 files, though one pre-existing bug was discovered.

Architecture: Strong - The shift to agent-skills-spec format is the right direction, simplifying distribution and making plugins more portable.

Security: Solid - Good input validation, proper cleanup, and safe git operations.

Status: ✅ Approved - All changes in this PR are high quality. The bug found is pre-existing and should be fixed in a separate PR.

• ✅ Properly scoped: fix(scripts):

Code Quality Assessment

Shell Script Security (scripts/install-plugin.sh)

✅ Security Strengths:

1. Input Validation (lines 104-107)

   if [[ ! "$PLUGIN_NAME" =~ ^[a-z0-9-]+$ ]]; then
     error "Invalid plugin name..."
   fi

   Prevents path traversal attacks

2. Sparse Checkout (lines 119-124)

   git config core.sparseCheckout true
   echo "plugins/$PLUGIN_NAME/" >> .git/info/sparse-checkout
   git pull -q --depth=1 origin "$BRANCH"

   • Downloads only necessary files (security + performance)
   • Uses --depth=1 to limit history
   • Validated plugin name prevents directory traversal

3. Cleanup Handler (lines 39-47)

   cleanup() {
     if [ -n "$TEMP_DIR" ] && [ -d "$TEMP_DIR" ]; then
       rm -rf "$TEMP_DIR"
     fi
   }
   trap cleanup EXIT

   Ensures temp files are cleaned up even on errors

4. Mode Flag Validation (lines 77-101)

   • Requires explicit mode flag (--claude, --cursor, --agents)
   • Fails fast with helpful error messages
   • No default mode (prevents accidental installations)

5. Directory Existence Checks (lines 127-137)

   • Verifies plugin directory exists before proceeding
   • Validates agent-skills-spec compliance (skills/ directory)
   • Clear error messages for users

6. jq Graceful Degradation (lines 181-206)

   • Checks if jq is available before using
   • Provides manual instructions if not available
   • No silent failures

✅ Best Practices:

• Uses set -e for fail-fast behavior (line 12)
• Colored output for better UX (lines 14-37)
• Comprehensive usage examples in error messages (lines 78-100)
• Clear next steps after installation (lines 213-225, 240-254, 269-282)

Adherence to Project Standards

Code Patterns (from .claude/rules/code-patterns.md):

• ✅ Shell script doesn't apply most code patterns (TypeScript-focused)
• ✅ Numeric separators not applicable to shell scripts
• ✅ Error handling follows shell best practices

Git Workflow (from .claude/rules/git-workflow.md):

• ✅ Follows conventional commits format
• ✅ Clear, descriptive commit messages
• ⚠️ First commit missing scope (see note above)

Documentation (from .claude/skills/documentation):

• ✅ README.md updates use encouraging, accessible tone
• ✅ AGENTS.md updates maintain directive, technical tone
• ✅ Clear audience distinction maintained

• ✅ No unnecessary file operations or loops
• ✅ Minimal external dependencies (git, optional jq)

Architecture Notes

agent-skills-spec Adoption:

• ✅ Excellent alignment with modern agent-skills-spec format
• ✅ Skills in plugins/*/skills/ directory structure
• ✅ YAML frontmatter + Markdown skill files
• ✅ Cross-platform compatibility (Claude Code, Cursor, Cody, Continue, etc.)
• ✅ Simplified distribution (git-based, no build artifacts)

Directory Structure Changes:

• ✅ .claude/plugins/ for Claude Code
• ✅ .agents/skills/ for universal agent discovery
• ✅ Marketplace configuration in .claude/settings.json

Missing Context

PR Description Missing: The PR has no description explaining:

• Why the MCP schema version was bumped (breaking changes? new features?)
• Whether this introduces breaking changes for users
• Link to MCP schema changelog or release notes
• Any migration steps needed

This context would help reviewers and future maintainers understand the schema update's motivation and impact.

Architecture Assessment

✅ Excellent Architecture Decisions:

1. agent-skills-spec Adoption

   • Modern format with YAML frontmatter + Markdown
   • Cross-platform compatibility (Claude Code, Cursor, Cody, Continue, etc.)
   • Skills in plugins/*/skills/ directory structure
   • Git-based distribution (no build artifacts)

2. Simplified Distribution

   • .claude/plugins/ for Claude Code
   • .agents/skills/ for universal agent discovery
   • Marketplace config in .claude/settings.json
   • Clear separation of concerns

3. Installation Improvements

   • Git sparse checkout reduces download size
   • --depth=1 minimizes git history
   • Proper validation at multiple levels
   • Minimal external dependencies

---

Performance Considerations

✅ Install Script Performance:

• Sparse checkout significantly reduces download size (only single plugin directory)
• --depth=1 reduces git history download
• No unnecessary file operations or loops
• Minimal external dependencies (git, optional jq)

---

Recommendations

Before Merging:

1. ✅ Code quality: All changes are production-ready
2. ⚠️ Add PR description: Explain MCP schema update rationale (non-blocking)
3. ⚠️ Consider scope in first commit: chore(mcp): instead of chore: (non-blocking)

After Merging:

1. 🐛 Fix MARKETPLACE.md bug: Add missing --claude flag at line 20 in follow-up PR

Code Quality Assessment

⭐ Security Analysis (scripts/install-plugin.sh)

✅ Excellent Security Practices:

1. Input Validation (lines 104-107)

   • Prevents path traversal with regex: ^[a-z0-9-]+$

2. Sparse Checkout (lines 119-124)

   • Downloads only necessary files
   • Uses --depth=1 to limit git history
   • Validated plugin name prevents directory traversal

3. Cleanup Handler (lines 39-47)

   • Ensures temp files removed on exit/error
   • Uses trap for reliable cleanup

4. Mode Validation (lines 77-101)

   • Requires explicit mode flag (no defaults)
   • Comprehensive error messages with examples

5. Directory Checks (lines 127-137)

   • Verifies plugin exists
   • Validates agent-skills-spec compliance (skills/ directory)

6. Graceful jq Handling

   • Checks availability before use
   • Provides manual instructions if unavailable

⭐ Adherence to Project Standards

Git Workflow (.claude/rules/git-workflow.md):

• ✅ Follows conventional commits format
• ✅ Clear, descriptive commit messages with Co-Authored-By trailers
• ⚠️ First commit missing scope (non-blocking)

Code Patterns (.claude/rules/code-patterns.md):

• ✅ Shell script - TypeScript patterns not applicable
• ✅ Error handling follows shell best practices

Documentation Standards:

• ✅ README.md uses encouraging, accessible tone
• ✅ AGENTS.md maintains directive, technical tone
• ✅ Clear audience distinction

🐛 Issues Found

1. Pre-Existing Bug in MARKETPLACE.md:20 (NOT introduced by this PR)

Location: docs/MARKETPLACE.md:20

The Quick Start example is missing the required --claude flag:

# ❌ Current (line 20) - will fail with error
curl -fsSL https://raw.githubusercontent.com/youdotcom-oss/dx-toolkit/main/scripts/install-plugin.sh | bash -s teams-anthropic-integration

# ✅ Should be
curl -fsSL https://raw.githubusercontent.com/youdotcom-oss/dx-toolkit/main/scripts/install-plugin.sh | bash -s teams-anthropic-integration --claude

Why this fails: The install script validates inputs at lines 77-78:

if [ -z "$PLUGIN_NAME" ] || [ -z "$INSTALL_MODE" ]; then
  error "Usage: curl -fsSL ... | bash -s <plugin-name> --claude|--cursor|--agents

Impact: Users following the Quick Start guide will encounter an error instead of successful installation.

Note: This bug has been identified in all four previous Claude reviews but has not been fixed. It exists on the main branch and was NOT introduced by this PR.
