Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-starter-kit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (install.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent Starter Kit

The skills, plugins, and MCP servers worth installing the moment you open a new agent — bundled into one install. Instead of hunting them down one by one, run the installer and the agent starts with real capabilities: it can find and install more skills on demand, drive a browser, reason with guardrails, design clean UI (Arabic included), review its own code, and automate the browser + GitHub.

What it installs

Tier 1 — Skills (work on 70+ agents via npx skills: Claude Code, Codex, Cursor, …):

Skill What it gives the agent
find-skills Discovers and installs any other skill on demand — the meta-skill
agent-browser A real browser the agent controls itself (open, click, fill, verify)
karpathy-guidelines Behavior rules: no silent assumptions, minimal solutions, verify before acting
ui-ux-pro-max Design-system intelligence — styles, color palettes, font pairings
caveman Blunt, no-fluff answers when you want signal over politeness
arabic-design Clean Arabic in AI-generated designs (fixes the letter-spacing/RTL traps)

Tier 2 — Plugins / MCPs (Claude Code only):

Plugin / MCP What it gives Claude Code
frontend-design Anthropic's design guidance for polished, non-generic UI
superpowers TDD + subagent orchestration workflow (brainstorm → design → build → review)
code-review /code-review on any branch/PR — scored, actionable review
playwright (MCP) Browser automation & end-to-end testing
github (MCP) Read/manage GitHub repos, PRs, and issues from the agent
claude-md-management Keeps your CLAUDE.md files organized and current

How to run it

From the skill directory:

bash install.sh                 # Claude Code — installs everything
bash install.sh --agent cursor  # Cursor — installs the Tier 1 skills
bash install.sh --agent codex   # Codex  — installs the Tier 1 skills
bash install.sh --agent '*'     # every detected agent
bash install.sh --skills-only   # skip the Claude-Code-only plugins/MCPs

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
