Use when setting up a project with the plumb-line discipline — interviews the builder to find their source-truth layer and layering, generates a domain-neutral ruleset, and installs parameterized enforcement (boundary check, test gate, pre-commit gate, branch guard) for the project's language. Ships no default layers and invents no answers.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Bootstrap a project with plumb-line

Part of the five-skill flow: find your fit with `plumb-line-adopt`, learn the
discipline with `plumb-line-method`, set the project up here, review changes
with `plumb-line-audit`, and apply findings with `plumb-line-remediate`.

REQUIRED READING FIRST: `reference/portable-principles.md` and
`adapters/adapter-contract.md` (plugin root).
If either file cannot be read, stop immediately and report which file is missing. Do not proceed from memory.

## Two entries: full bootstrap vs. declaration-only (mid-audit)

This skill has two entry modes. **Full bootstrap** — the builder asked for
setup — runs every step below. **Declaration-only** — `plumb-line-audit`
invoked this skill because the project declares no architecture and the audit
needs that context before proceeding — runs a deliberately two-minute detour:

- Ask ONLY interview questions 1–3 (layers + direction; source-truth layer;
  composition root). The audit needs the declaration, not the ceremony.
- Write the ruleset from those answers (Step 3), marking every section the
  interview did not reach as `planned` — an un-asked question must not read as
  an answered one.

How to install

The exact contents, by fingerprint
mdr add slopstopper/plumb-line/plumb-line-bootstrap@sha256:122b1b92622d8e62

The line at the top of this page pins the label git:20261003.edc1711, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
