bootstrap

bootstrap is a skill for Claude Code from rp1-run/rp1. It costs 21 tokens per session (3,539 once invoked), scanned A, original, Apache-2.0.

A workflow for starting a new software project by interviewing the user and creating a project plan, then optionally revising and applying that plan.

In plain words
What is it for?
It helps collect initial requirements, define project preferences, make a bounded plan, and scaffold the project.
Why use it?
It provides structure for a greenfield project, meaning one started from little or no existing code, while keeping unfinished decisions in saved project documents.

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 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.

How it starts

The opening of the file, as written. The whole thing — 303 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bootstrap

The top-level skill owns every user-facing question. The retained scaffolder is a bounded, non-interactive worker invoked only after the answer it needs is durable in the target knowledge base.

{% include_shared "parent-owned-interview.md" %}

Invariants

  • Keep metadata.is_workflow: false; bootstrap may start outside an initialized project.
  • Known _TBD_ sections in charter.md and preferences.md are the only resume state.
  • Workflow events are telemetry only. Never use them to decide which question or action comes next.
  • Do not create scratch pads, bootstrap markers, checkpoint comments, context sidecars, relay envelopes, continuation payloads, or generalized scaffold probes.
  • Use the same parent-owned topology on every platform. Do not use platform-specific interaction tags.
  • MUST NOT dispatch inside either interview loop. Across one invocation, dispatch at most one PLAN action, one optional REVISE action, and one APPLY action.

Procedure

1. Validate Every Project Name Before Effects

Begin from a non-mutating directory inventory. Inspect only the current directory and safe-named direct children when looking for resumable work; do not recurse through arbitrary directories.

Validate every supplied, inferred, or recovered project name against ^[a-z0-9][a-z0-9-]*$ before using it as a path segment. Do not trim, sanitize, lowercase, or otherwise rewrite a candidate. Reject separators, .., whitespace, globs, punctuation other than -, an empty name, or a leading hyphen with actionable lowercase-kebab-case guidance.

Target discovery:

  1. Enumerate the current directory name and direct-child names without entering them.
  2. Discard a name unless it passes the project-name regex, then retain only candidates with their own .rp1/project_id. Never derive a candidate path from an unsafe name, and never treat an ancestor project as candidate initialization.
  3. If one initialized candidate exists, offer to inspect and use it. If several exist, present only the validated names and ask the user to choose one or provide a new name. If none exists and no argument was supplied, infer the current directory basename only when the current directory is already its own rp1 project; otherwise ask for a name.
  4. Do not call a selected initialized target resumable until Section 2 resolves its canonical directories and {targetKbRoot}/preferences.md exists. A resumable candidate exists only when its resolved {targetKbRoot}/preferences.md exists. Do not inspect run state, marker files, package manifests, or expected scaffold outputs to infer resume state.

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 rp1-run/rp1 (38 stars, last pushed yesterday), licensed Apache-2.0. It adds 21 tokens to every session and 3,539 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 2026-09-07.
