A comprehensive extension toolkit that transforms Claude Code into a specialized development powerhouse.

claude-mods is a production-ready plugin that extends Claude Code with 87 specialized skills, 3 expert agents, 13 output styles, 11 hooks, and modern CLI tools designed for real-world development workflows. Whether you're debugging React hooks, optimizing PostgreSQL queries, or building production CLI applications, this toolkit equips Claude with the domain expertise and procedural knowledge to work at expert level across multiple technology stacks.

Built on the Agent Skills specification (an open standard backed by Anthropic, Vercel, Google, Microsoft, and 40+ agent platforms), claude-mods fills critical gaps in Claude Code's capabilities: persistent session state that survives across machines, on-demand expert knowledge for specialized domains, token-efficient modern CLI tools (10-100x faster than traditional alternatives), and proven workflow patterns for TDD, code review, and feature development. The toolkit implements Anthropic's recommended patterns for long-running agents, ensuring your development context never vanishes when sessions end.

From Python async patterns to Rust ownership models, from AWS Fargate deployments to Craft CMS development - claude-mods provides the specialized knowledge and tools that transform Claude from a general-purpose assistant into a domain expert who understands your stack, remembers your workflow, and ships production code.

3 agents. 87 skills. 13 styles. 11 hooks. 7 rules. One install.

Recent Updates

v3.0.0 (June 2026)

• Skills-first restructure - Breaking: the expert-agent layer was cut from 23 to 3. Per Anthropic's guidance, knowledge belongs in skills (progressive disclosure, single source of truth) and subagents are reserved for context isolation — so all domain-knowledge agents became -ops skills (the 11 language/framework experts → their twins; cypress/cloudflare/bash/craftcms/payloadcms/asus-router → new skills; claude-architect/aws-fargate folded into existing skills). The 3 remaining agents are pure isolation/worker roles: git-agent (background commits/PRs), firecrawl-expert (noisy multi-page scrapes), project-organizer (bulk restructure). Dispatching skills now route general-purpose agents that preload skill references.
• claude-code-ops skill - claude-code-debug/-headless/-hooks merged and rebuilt from current official docs: the 30-event hook catalog with per-event JSON contracts, today's SKILL.md frontmatter spec, headless/CLI reference, and extension-debugging decision trees.
• Three new skills, doc-verified - claude-api-ops (Messages API, tool use, prompt caching, structured outputs, Agent SDK), playwright-ops (selector hierarchy, fixtures, CI sharding, flake hunting), terraform-ops (state, modules, OIDC plan/apply, secrets).
• Live security guards, zero hand-wiring - config-change-guard.sh scans Claude settings files for worm-persistence IOCs the moment they're edited; worktree-guard.sh mechanically enforces worktree boundaries. Plugin-level hooks/hooks.json auto-wires the security set on install.
• Skill Resource Protocol - one build standard for skill scripts and assets (docs/SKILL-RESOURCE-PROTOCOL.md), headlined by the staleness-verifier pattern: offline checks gate PR CI, live drift checks run weekly without ever blocking a PR. Four verifiers ship with it.
• fleet-ops v2 - repositioned as landing discipline (sequential queue, test-gated merge, pre-land scrub, one-shot revert, new fleet track) on top of native agent teams and background agents, which now own session spawning.
• Docs that can't rot - new CHANGELOG.md; a CI doc-drift gate fails the build when README counts diverge from disk or a link goes ghost; every skill's behavioural suite runs in CI; /save + /sync repositioned as portable, team-shareable state alongside native auto-memory.
