claude-skills

A Claude Code skill marketplace maintained by snkrheadz. Goal: a new teammate (engineer / PM) can use Claude Code in the same environment from day one.

We intentionally keep this lean. Anything the official Claude Code commands already cover (code review, simplification, app verification, committing, project init) is not duplicated here — see Covered by official Claude Code. This repo only ships the gaps.

Big picture: distribution has two channels

A plugin alone is not enough. By design, Claude Code cannot distribute permissions.deny (the security deny-list) or the global CLAUDE.md (your working philosophy) through a plugin, so those go through a separate channel.

Channel	What	How
A. Plugins	skills / agents / hooks	/plugin marketplace add → /plugin install
B. Settings + philosophy	permission deny-list / CLAUDE.md	paste into ~/.claude/settings.json + install CLAUDE.md

---

Channel A: install the plugins

1. Add this marketplace (everyone)

/plugin marketplace add snkrheadz/claude-skills

Works for private repos too. A manual add reuses your local git auth (gh auth login / SSH / Keychain), so if you can git clone it, you can add it. Only set GITHUB_TOKEN (with repo scope) if you also want auto-update on startup.

2. Install Core first (everyone)

/plugin install core@claude-skills

What Core ships (role-agnostic):

• first-principles — rethink a problem from fundamentals
• teach-session — teach back the work just done (great for onboarding)
• html-output — emit specs / reviews / reports as rich HTML
• pre-tool-guard hook — block access to sensitive files (defense in depth)

3. Install role packs

PM / business

# Our own business assets (maintained by snkrheadz)
/plugin install pm@claude-skills          # 業務定義シート (task definition sheet) as A4 HTML

# PM lifecycle (external, MIT, recommended for non-developers)
/plugin marketplace add phuryn/pm-skills
/plugin install pm-product-discovery@pm-skills   # discovery / prioritization / interviews
/plugin install pm-product-strategy@pm-skills    # strategy / canvases / pricing
/plugin install pm-execution@pm-skills           # PRD / OKR / roadmap / sprint
/plugin install pm-market-research@pm-skills     # personas / market sizing / competitors
# Install only what you need. All 9 plugins: https://github.com/phuryn/pm-skills

# Document generation (official, docx/pptx/xlsx/pdf)
/plugin install document-skills@anthropic-agent-skills

Engineer

/plugin install eng@claude-skills

This pack deliberately does not re-implement review/simplify/verify/commit — those are official commands now (see below). It ships the workflow gaps around them:

• Skills (7): merge-pr review-inbox test-and-fix refactor-swarm techdebt trace-dataflow db-query
• Agents (8): code-architect architecture-reviewer verify-shell migration-assistant oncall-guide state-machine-diagram aws-best-practices-advisor gcp-best-practices-advisor

Recommended alongside the official LSP plugins:

/plugin install gopls-lsp@claude-plugins-official        # Go
/plugin install typescript-lsp@claude-plugins-official   # TS

Research (role-agnostic, optional)

For anyone investigating AI/ML papers, APIs, and models — any role can add it.

/plugin install research@claude-skills

Agents (3): arxiv-ai-researcher (paper discovery & synthesis), gemini-api-researcher (Gemini API capabilities & usage), huggingface-spaces-researcher (HF Spaces / model discovery).

Marketer / Designer

These roles are served almost entirely by official Anthropic plugins — we no longer ship a custom pack for them.

# Marketer
/plugin install document-skills@anthropic-agent-skills   # brand-guidelines, internal-comms, doc-coauthoring
# + the deep-research skill; landing pages via frontend-design@claude-plugins-official

# Designer
/plugin install frontend-design@claude-plugins-official
/plugin install document-skills@anthropic-agent-skills   # canvas-design, theme-factory, algorithmic-art, slack-gif-creator

Covered by official Claude Code

These workflows ship with Claude Code itself, so this marketplace intentionally omits them. Use the official commands directly:

Need	Official command
Review the current diff / a PR	/code-review (/code-review ultra [PR#] for deep multi-agent cloud review), /review
Security review	/security-review
Simplify / de-duplicate code	/simplify
Verify a change by running the app	/verify, /run
Commit	Claude Code commits natively (or the commit-commands plugin)
Initialize CLAUDE.md / project config	/init, the update-config skill
Claude Code / Agent SDK / API how-to	the official claude-code-guide agent
