bootstrap

bootstrap is a skill for Claude Code, Codex from fullstack455/deer-flow. It costs 0 tokens per session (1,101 once invoked), scanned A, a copy of bootstrap, MIT.

An onboarding skill for creating a personalised SOUL.md file, which defines an AI partner’s identity, behaviour, and working style. It gathers this information through a short conversation and uses project templates and guidance.

In plain words
What is it for?
It helps set up a new AI partner, define its personality and working rules, and update those instructions when the user’s preferences change.
Why use it?
It turns vague preferences into written instructions that the AI partner can follow consistently. This gives the agent a clearer understanding of the user’s needs and interaction style.

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 1mo 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.

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.

Origin

This is a copy

100% identical to bootstrap — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Bootstrap Soul

A conversational onboarding skill. Through 5–8 adaptive rounds, extract who the user is and what they need, then generate a tight SOUL.md that defines their AI partner.

Architecture

bootstrap/
├── SKILL.md                          ← You are here. Core logic and flow.
├── templates/SOUL.template.md        ← Output template. Read before generating.
└── references/conversation-guide.md  ← Detailed conversation strategies. Read at start.

Before your first response, read both:

  1. references/conversation-guide.md — how to run each phase
  2. templates/SOUL.template.md — what you're building toward

Ground Rules

  • One phase at a time. 1–3 questions max per round. Never dump everything upfront.
  • Converse, don't interrogate. React genuinely — surprise, humor, curiosity, gentle pushback. Mirror their energy and vocabulary.
  • Progressive warmth. Each round should feel more informed than the last. By Phase 3, the user should feel understood.
  • Adapt pacing. Terse user → probe with warmth. Verbose user → acknowledge, distill, advance.
  • Never expose the template. The user is having a conversation, not filling out a form.

Conversation Phases

The conversation has 4 phases. Each phase may span 1–3 rounds depending on how much the user shares. Skip or merge phases if the user volunteers information early.

Phase Goal Key Extractions
1. Hello Language + first impression Preferred language
2. You Who they are, what drains them Role, pain points, relationship framing, AI name
3. Personality How the AI should behave and talk Core traits, communication style, autonomy level, pushback preference
4. Depth Aspirations, blind spots, dealbreakers Long-term vision, failure philosophy, boundaries

Phase details and conversation strategies are in references/conversation-guide.md.

Extraction Tracker

Mentally track these fields as the conversation progresses. You need all required fields before generating.

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.
