claude-mods

A comprehensive extension toolkit for Claude Code that transforms your AI coding assistant into a powerhouse development environment.

23 expert agents. 10 slash commands. 30 skills. Custom output styles. One plugin install.

Why claude-mods?

Claude Code is powerful out of the box, but it has gaps. This toolkit fills them:

• Session continuity — TodoWrite tasks vanish when sessions end. We fix that with /plan --save and /plan --load, implementing Anthropic's recommended pattern for long-running agents.

• Expert-level knowledge on demand — 21 specialized agents covering React, TypeScript, Python, AWS, PostgreSQL, and more. Each agent is deeply researched with real-world patterns, not generic advice.

• Modern CLI tools — Stop using grep, find, and cat. Our rules automatically prefer ripgrep, fd, eza, and bat — 10-100x faster and token-efficient.

• Smart web fetching — A fallback hierarchy that actually works: WebFetch → Jina Reader → Firecrawl. No more "I can't access that URL."

• Workflow patterns — TDD cycles, code review, feature development, debugging — all documented with Anthropic's best practices.

Key Benefits

• Persistent task state — Pick up exactly where you left off, even across machines
• Domain expertise — Agents trained on framework docs, not just general knowledge
• Token efficiency — Modern CLI tools produce cleaner output, saving context window
• Team sharing — Git-trackable state files work across your whole team
• Production-ready — Validated test suite, proper plugin format, comprehensive docs
• Extended thinking — Built-in guidance for "think hard" and "ultrathink" triggers
• Zero lock-in — Standard Claude Code plugin format, toggle on/off anytime

just test

# Or run directly
bash validate.sh

# Windows
powershell validate.ps1

What's Validated

• YAML frontmatter syntax
• Required fields (name, description)
• Naming conventions (kebab-case)
• File structure (agents/.md, skills//SKILL.md)

Available Tasks

cd tests
just              # List all tasks
just test         # Run full validation
just validate-yaml # YAML only
just validate-names # Naming only
just stats        # Count extensions
just list-agents  # List all agents

Session Continuity

The /plan command fills a gap in Claude Code's native session management.

The problem: Claude Code's --resume flag restores conversation history, but TodoWrite task state does not persist between sessions—by design. Claude Code treats each session as isolated; the philosophy is that persistent state belongs in files you control.

TodoWrite tasks are stored at ~/.claude/todos/[session-id].json and deleted when the session ends. This is intentional.

The solution: /plan --save and /plan --load implement the pattern from Anthropic's Effective Harnesses for Long-Running Agents:

"Every subsequent session asks the model to make incremental progress, then leave structured updates."

What Persists vs What Doesn't

Claude Code Feature	Persists?	Location
Conversation history	Yes	Internal (use --resume)
CLAUDE.md context	Yes	./CLAUDE.md
TodoWrite tasks	No	Deleted on session end
Plan Mode state	No	In-memory only

Session Workflow

Session 1:
  /sync                              # Bootstrap - read project context
  [work on tasks]
  /plan --save "Stopped at auth module"  # Writes .claude/session-cache.json

Session 2:
  /sync                              # Read project context
  /plan --load                       # Restore TodoWrite, show what changed
  → "In progress: Auth module refactor"
  → "Notes: Stopped at auth module"
  /plan --status                     # Quick status check anytime

Why Not Just Use --resume?

Feature	--resume	/plan --save/--load
Conversation history	Yes	No
TodoWrite tasks	No	Yes
Git context	No	Yes
Human-readable summary	No	Yes
Git-trackable	No	Yes
Works across machines	No	Yes (if committed)
Team sharing	No	Yes

Use both together: claude --resume for conversation context, /plan --load for task state.

Updating

git pull

Then re-run the install script to update your global Claude configuration.
