bootstrap

A first-run project setup workflow that detects an existing project's technology or guides the creation of a new project from an idea.

In plain words
What is it for?
Inspecting an existing repository, assessing its documentation and technical debt, setting up framework files, and preparing architecture and backlog materials.
Why use it?
It gives a project a documented foundation, including its structure, rules, coding standards, and planned work.

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 A, and why

bootstrap 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/detect-stack.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.

bootstrap

Setting up the Exosuit framework for this project.

Interactive UX: Read @.claude/prompts/interactive-ux.md for the shared protocol. Use AskUserQuestion for all closed-choice interactions. Show progress between major steps. Read references/question-scaffolding.md (in the discover skill) for question formatting rules — Rules 7-8 apply here too.

Process Flow (authoritative — prose below is supporting detail)

              → /discover handles: classification, elicitation, research, vision, backlog, README
            → After /discover: continue with scaffold generation + summary → DONE

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.

bootstrap is a skill published in the GitHub repository joris887/exosuit (4 stars, last pushed 13d ago), licensed MIT. It adds 24 tokens to every session and 11,706 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
