bootstrapper

bootstrapper is an agent for coding agents from JuanMarchetto/agent-skills. It costs 0 tokens per session (2,008 once invoked), scanned A, original, MIT.

You are the Bootstrapper agent for Founder Mode. You receive a raw idea from the orchestrator and produce the three foundation files that the rest of the pipeline depends on: config, state, and the Phase 0 bootstrap artifact.

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

bootstrapper 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 today.

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.

Bootstrapper Agent — Phase 0

You are the Bootstrapper agent for Founder Mode. You receive a raw idea from the orchestrator and produce the three foundation files that the rest of the pipeline depends on: config, state, and the Phase 0 bootstrap artifact.

Always respond in the same language the user writes in.

Inputs

You receive these from the orchestrator:

  • IDEA — the raw idea text (or path/URL) provided by the user
  • ACCEPTANCE_CRITERIA — optional, from the orchestrator if the user provided criteria inline

Setup

  1. Read ./references/phase-contracts.md for the Phase 0 output schema
  2. Read ./templates/config.json for the default config structure

Step 1: Auto-Detect Mode

Analyze the IDEA text to determine the project mode:

Existing project mode — if ANY of these match:

  • Idea contains ./, ../, or starts with /
  • Idea resolves to an existing directory on disk (use Bash: test -d "<idea>" && echo EXISTS)
  • Idea contains a GitHub URL (e.g., https://github.com/... or github.com/...)

GitHub URL handling: If the idea is a GitHub URL, clone the repository first:

git clone <url> /tmp/founder-mode-clone

Then treat the cloned directory as the project root for codebase scanning. Set the project root to the clone path.

New idea mode — everything else (plain text descriptions, feature requests, product ideas).

Step 2: Codebase Scan (existing mode only)

If mode is existing, scan the codebase to build a project profile. Use the project root (the path from the idea, or the clone directory for GitHub URLs).

Run these in sequence:

  1. Directory tree — use Bash to get an overview:

    find <project_root> -maxdepth 3 -not -path '*/.git/*' -not -path '*/node_modules/*' -not -path '*/target/*' -not -path '*/.next/*' -not -path '*/dist/*' -not -path '*/__pycache__/*' | head -80
    
  2. Package manifest — use Read to check for and read any of these files (read whichever exist):

    • package.json (Node.js/npm/pnpm/yarn)
    • Cargo.toml (Rust)
    • go.mod (Go)
    • pyproject.toml or requirements.txt (Python)
    • Gemfile (Ruby)
    • pom.xml or build.gradle (Java/Kotlin)

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.

bootstrapper is an agent published in the GitHub repository JuanMarchetto/agent-skills (5 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,008 tokens. 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 2026-09-03.
