Reza Rezvani 2f57ef8948 feat(agenthub): add AgentHub plugin with cross-domain examples, SEO optimization, and docs site fixes
- AgentHub: 13 files updated with non-engineering examples (content drafts,
  research, strategy) — engineering stays primary, cross-domain secondary
- AgentHub: 7 slash commands, 5 Python scripts, 3 references, 1 agent,
  dry_run.py validation (57 checks)
- Marketplace: agenthub entry added with cross-domain keywords, engineering
  POWERFUL updated (25→30), product (12→13), counts synced across all configs
- SEO: generate-docs.py now produces keyword-rich <title> tags and meta
  descriptions using SKILL.md frontmatter — "Claude Code Skills" in site_name
  propagates to all 276 HTML pages
- SEO: per-domain title suffixes (Agent Skill for Codex & OpenClaw, etc.),
  slug-as-title cleanup, domain label stripping from titles
- Broken links: 141→0 warnings — new rewrite_skill_internal_links() converts
  references/, scripts/, assets/ links to GitHub source URLs; skills/index.md
  phantom slugs fixed (6 marketing, 7 RA/QM)
- Counts synced: 204 skills, 266 tools, 382 refs, 16 agents, 17 commands,
  21 plugins — consistent across CLAUDE.md, README.md, docs/index.md,
  marketplace.json, getting-started.md, mkdocs.yml
- Platform sync: Codex 163 skills, Gemini 246 items, OpenClaw compatible

Monorepo Navigator — Agent Skill for Codex & OpenClaw Monorepo Navigator. Agent skill for Claude Code, Codex CLI, Gemini CLI, OpenClaw.

Monorepo Navigator

:material-rocket-launch: Engineering - POWERFUL :material-identifier: `monorepo-navigator` :material-github: Source
Install: claude /plugin install engineering-advanced-skills

Tier: POWERFUL
Category: Engineering
Domain: Monorepo Architecture / Build Systems


Overview

Navigate, manage, and optimize monorepos. Covers Turborepo, Nx, pnpm workspaces, and Lerna. Enables cross-package impact analysis, selective builds/tests on affected packages only, remote caching, dependency graph visualization, and structured migrations from multi-repo to monorepo. Includes Claude Code configuration for workspace-aware development.


Core Capabilities

  • Cross-package impact analysis — determine which apps break when a shared package changes
  • Selective commands — run tests/builds only for affected packages (not everything)
  • Dependency graph — visualize package relationships as Mermaid diagrams
  • Build optimization — remote caching, incremental builds, parallel execution
  • Migration — step-by-step multi-repo → monorepo with zero history loss
  • Publishing — changesets for versioning, pre-release channels, npm publish workflows
  • Claude Code config — workspace-aware CLAUDE.md with per-package instructions

When to Use

Use when:

  • Multiple packages/apps share code (UI components, utils, types, API clients)
  • Build times are slow because everything rebuilds when anything changes
  • Migrating from multiple repos to a single repo
  • Need to publish packages to npm with coordinated versioning
  • Teams work across multiple packages and need unified tooling

Skip when:

  • Single-app project with no shared packages
  • Team/project boundaries are completely isolated (polyrepo is fine)
  • Shared code is minimal and copy-paste overhead is acceptable

Tool Selection

Tool Best For Key Feature
Turborepo JS/TS monorepos, simple pipeline config Best-in-class remote caching, minimal config
Nx Large enterprises, plugin ecosystem Project graph, code generation, affected commands
pnpm workspaces Workspace protocol, disk efficiency workspace:* for local package refs
Lerna npm publishing, versioning Batch publishing, conventional commits
Changesets Modern versioning (preferred over Lerna) Changelog generation, pre-release channels

Most modern setups: pnpm workspaces + Turborepo + Changesets


Turborepo

→ See references/monorepo-tooling-reference.md for details

Workspace Analyzer

python3 scripts/monorepo_analyzer.py /path/to/monorepo
python3 scripts/monorepo_analyzer.py /path/to/monorepo --json

Also see references/monorepo-patterns.md for common architecture and CI patterns.

Common Pitfalls

Pitfall Fix
Running turbo run build without --filter on every PR Always use --filter=...[origin/main] in CI
workspace:* refs cause publish failures Use pnpm changeset publish — it replaces workspace:* with real versions automatically
All packages rebuild when unrelated file changes Tune inputs in turbo.json to exclude docs, config files from cache keys
Shared tsconfig causes one package to break all type-checks Use extends properly — each package extends root but overrides rootDir / outDir
git history lost during migration Use git filter-repo --to-subdirectory-filter before merging — never move files manually
Remote cache not working in CI Check TURBO_TOKEN and TURBO_TEAM env vars; verify with turbo run build --summarize
CLAUDE.md too generic — Claude modifies wrong package Add explicit "When working on X, only touch files in apps/X" rules per package CLAUDE.md

Best Practices

  1. Root CLAUDE.md defines the map — document every package, its purpose, and dependency rules
  2. Per-package CLAUDE.md defines the rules — what's allowed, what's forbidden, testing commands
  3. Always scope commands with --filter — running everything on every change defeats the purpose
  4. Remote cache is not optional — without it, monorepo CI is slower than multi-repo CI
  5. Changesets over manual versioning — never hand-edit package.json versions in a monorepo
  6. Shared configs in root, extended in packages — tsconfig.base.json, .eslintrc.base.js, jest.base.config.js
  7. Impact analysis before merging shared package changes — run affected check, communicate blast radius
  8. Keep packages/types as pure TypeScript — no runtime code, no dependencies, fast to build and type-check
