Add Claude Code plugin marketplace

[plx]

Expand agentic-navigation-guide into a full Claude Code plugin marketplace with comprehensive resources for creating and maintaining navigation guides.

This PR adds:

• 4 skills: authoring guides, summarizing items, revising guides, and configuring hooks
• 3 agents: summarize-item, create-guide, and refresh-guide
• 2 new commands: setup-guide and update-guide (plus existing verify/check)
• Enhanced plugin metadata updated to v0.2.0

All documentation includes practical examples, anti-patterns to avoid, and clear workflows for both manual and automated guide management.

Pull Request Review: Add Claude Code Plugin Marketplace

I've reviewed PR #7 and have the following feedback:

Overall Assessment

This is an excellent addition that transforms the tool into a comprehensive Claude Code plugin with rich educational resources. The documentation is well-structured, practical, and follows good patterns. The code changes themselves are minimal (only metadata files), making this a low-risk, high-value PR.

---

Strengths

1. Comprehensive Documentation: The skills, agents, and commands provide clear, actionable guidance with excellent examples and anti-patterns
2. Practical Examples: Every document includes realistic scenarios that users will encounter
3. Consistent Structure: All markdown files follow a consistent format with YAML frontmatter
4. Well-Organized: The directory structure (skills/, agents/, commands/, hooks/) is logical and discoverable
5. Updated Navigation Guide: The AGENTIC_NAVIGATION_GUIDE.md correctly reflects all the new files with appropriate comments

---

Issues Found

1. Missing name Field in Command Files

The commands/*.md files have only description in the YAML frontmatter, while skills and agents have both name and description. For consistency, commands should also include a name field:

Files affected:

• commands/check-guide.md
• commands/setup-guide.md
• commands/update-guide.md
• commands/verify-guide.md

Suggested fix:

---
name: check-guide
description: Check navigation guide syntax without filesystem verification
---

2. Truncated Content in skills/configuring-hooks.md

The diff output for skills/configuring-hooks.md appears to be cut off at line 100. The file should be reviewed to ensure it's complete, particularly:

• The GitHub Actions section appears incomplete
• Pre-commit hook configuration may be missing
• Examples and guidelines might be truncated

Action needed: Verify the file is complete with all sections

3. Hook Configuration May Trigger Too Broadly

In hooks/hooks.json, the matcher Write|Edit|Bash will trigger verification after every Bash command, which could be noisy for commands unrelated to file changes (e.g., git log, cargo --version).

Current:

"matcher": "Write|Edit|Bash"

Consideration: This is probably acceptable for the default hook, but users should be made aware they can customize this. The documentation in skills/configuring-hooks.md should emphasize this.

4. Plugin Installation Path Uses Repository URL

In skills/configuring-hooks.md:33-34, the installation instructions reference the GitHub repo:

/plugin marketplace add https://github.com/plx/agentic-navigation-guide
/plugin install agentic-navigation-guide@agentic-navigation-guide-marketplace

Questions:

• Is this the correct installation path for when the plugin is published?
• Should there be additional instructions for local development/testing?

---

Minor Suggestions

1. Version Bump Documentation

The version was bumped to 0.2.0 in plugin.json. Consider:

• Updating the README.md with a changelog section
• Documenting what changed between 0.1.x and 0.2.0
• Adding version compatibility notes if needed

2. Cross-References Between Documents

The documents reference each other well ("/verify-guide", etc.), but some additional cross-references could be helpful:

• agents/create-guide.md could reference skills/authoring-guide.md
• agents/refresh-guide.md could reference skills/revising-guide.md
• commands could reference the corresponding agents

3. Example Commands Use Slash Syntax

The commands/*.md files show usage as:

/setup-guide

But earlier in the docs, CLI usage is shown as:

agentic-navigation-guide verify

Clarification needed: Are these slash commands Claude Code plugin commands, or shell aliases? The documentation should clarify the relationship between:

• CLI commands (agentic-navigation-guide <cmd>)
• Plugin commands (/setup-guide)

4. TODOs in Command Files

Files like commands/check-guide.md:34 contain:

<!-- TODO: Customize this command description or add usage examples -->

These should either be addressed or removed before merging.

---

Security & Performance

No security concerns identified. All files are documentation and metadata.

No performance concerns. The hook runs verification which should be fast for typical projects.

---

Testing Recommendations

Before merging, verify:

1. File Completeness: Check that skills/configuring-hooks.md is complete
2. Plugin Installation: Test the plugin installation workflow end-to-end
3. Hook Functionality: Verify the PostToolUse hook works as expected
4. Navigation Guide: Run cargo run -- verify to ensure the updated guide is valid
5. Cross-References: Test that all internal command references work (/verify-guide, etc.)

---

Code Quality: ✅ Excellent

The JSON files are well-formed and the markdown is properly structured.

Documentation Quality: ✅ Outstanding

Comprehensive, practical, and well-organized.

Potential Bugs: ⚠️ Minor (TODOs, possible truncation)

Test Coverage: ⚠️ N/A (documentation-only PR)

Consider adding integration tests that verify the plugin metadata and hook configuration are valid.

---

Recommendation

Approve with minor revisions. Address the missing name fields in command files and verify the configuring-hooks.md file is complete, then this is ready to merge.

Great work expanding this into a full-featured plugin marketplace!

Pull Request Review: Add Claude Code Plugin Marketplace

Great work on this comprehensive expansion! This PR transforms the navigation guide tool into a full-featured Claude Code plugin with excellent documentation.

---

Strengths

1. Excellent Documentation Quality

• The skills, agents, and commands documentation is clear, well-structured, and practical
• Great use of examples throughout (e.g., authoring-guide.md has good vs bad comment examples)
• Comprehensive workflows with step-by-step processes
• Proper frontmatter metadata for Claude Code integration

2. Well-Designed Plugin Structure

• Logical separation: skills (how-to guides), agents (automated workflows), commands (CLI wrappers)
• The 4 skills + 3 agents + 4 commands provide comprehensive coverage
• Plugin metadata files (.claude-plugin/plugin.json, marketplace.json) are properly formatted

3. Developer Experience Improvements

• Makefile: Excellent addition with sensible targets (make ci, make install-hooks)
• pre-commit hook: Comprehensive checks (fmt, clippy, guide verification)
• hooks.json: PostToolUse hook for automatic verification is very clever

4. Updated Navigation Guide

• AGENTIC_NAVIGATION_GUIDE.md properly reflects the new structure
• Comments are descriptive and follow the project's own best practices

Issues and Recommendations

Critical Issues

None found! No security vulnerabilities, major bugs, or breaking changes detected.

Minor Issues and Suggestions

1. Makefile install-hooks Target (Lines 44-55)

• Issue: Complex fallback logic for worktree/submodule support may fail silently in edge cases
• Recommendation: Add error handling for the cp command inside the fallback to ensure chmod operation is also applied in the worktree case

2. scripts/pre-commit Graceful Degradation (Lines 34-43)

• Good: The script checks if agentic-navigation-guide is available before running verification
• Suggestion: Consider adding a comment explaining that users should run cargo install --path . for the hook to fully work

3. hooks/hooks.json Hook Matcher Scope (Line 4)

• Current: matcher Write|Edit|Bash
• Consideration: This triggers on all Bash commands, which might be overly aggressive. Even ls or git status will trigger verification
• Alternative: matcher Write|Edit (skip Bash entirely)
• Recommendation: Document this behavior in skills/configuring-hooks.md so users understand the tradeoff between correctness and latency

4. Documentation Missing Installation Prerequisites

• Several command docs reference the CLI without explaining installation (check-guide.md, verify-guide.md, setup-guide.md)
• Recommendation: Add a common Prerequisites section or link to installation instructions

---

Test Coverage

Observation: No new tests added for plugin metadata validation, hook configuration parsing, or command wrapper functionality.

Recommendation: Consider adding integration tests for plugin metadata validation. However, this is not blocking since the new content is primarily documentation and configuration.

---

Best Practices Assessment

• Code Quality: Excellent - Follows Rust conventions, shell scripts use set -e
• Security: No Concerns - No credential exposure, hooks use documented CLI flags
• Performance: Appropriate - Hook verification runs only on file changes
• Documentation: Outstanding - Clear, actionable, with examples

---

Suggestions for Follow-up PRs

These are not blockers, but nice-to-haves:

1. CI Workflow: Add a GitHub Actions workflow that uses the new make ci target
2. Plugin Tests: Add basic validation tests for plugin metadata
3. Example Repository: Create a companion repo demonstrating plugin usage
4. Version Alignment: Ensure version bump (0.2.0) is reflected in Cargo.toml

---

Final Verdict

Approval: LGTM with minor suggestions

This is a well-executed PR that significantly enhances the project's utility. The documentation quality is excellent, the tooling additions are thoughtful, and the integration with Claude Code is seamless.

Recommendations Summary:

• High Priority: Fix Makefile install-hooks error handling (1 min fix)
• Medium Priority: Document hook matcher behavior
• Low Priority: Add installation prerequisites to command docs
• Optional: Add plugin metadata validation tests

The minor issues noted above are suggestions for improvement, not blockers. The PR is ready to merge as-is, with optional refinements in future commits.

Great work!
