bootstrap

A skill that scans an existing project for agent add-ons and gathers them into shared folders and a capabilities configuration file. It looks across tools such as Claude, Cursor, Codex, and Gemini.

In plain words
What is it for?
Use it to inventory MCP servers, skills, rules, hooks, sub-agents, and plugins, then create or update the project’s shared configuration.
Why use it?
It reduces the manual work of finding scattered project settings and consolidating them.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 B, and why

bootstrap scanned grade B with 1 finding 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 2d ago.

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.

Reads MCP configurationmediumAgent snooping

mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.

- **For each MCP server**, prefer the most complete config from any source (e.g., if `.cursor/mcp.json` has env vars and `.claude/settings.json` doesn't, take Cursor's). Replace literal secrets with `${VarName}` placehol

What ships with it

3 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.

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.
