The brownfield on-ramp — onboard an EXISTING codebase by deriving the shared constitution (.spec/constitution.md) from the code that is actually there: the real lint/test/build commands, the real layout, the real conventions. Read-only analysis; it never creates a ticket dir, writes SPEC.md, or touches git. Run once per project before the first tiny-spec-create, and re-run in refresh mode after the codebase drifts. For a project with no code yet, use tiny-spec-scope instead.

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

# tiny-spec-adopt

The **brownfield front door**. Most real work is a ticket inside a system that already
exists — the stack, the layout, the test command, and the conventions are all already
decided, written down in config files and visible in the code. Interviewing a user about
them is asking for a worse copy of something you can read.

This skill reads the codebase and writes `.spec/constitution.md` from what's actually
there, then stops. It does **not** create a ticket dir, write a `SPEC.md`, switch
branches, or modify a single line of source.

**Starting from a blank page instead?** Use `tiny-spec-scope` — it interviews an idea
into features. The two are the suite's two front doors, and you generally want exactly
one of them.

## The one thing that matters most

The constitution is injected **whole** into every executor and reviewer, for the life of
the project. Its **Verification commands** block is the gate the reviewer literally
executes. So:

> **A derived gate that has never been run is the most dangerous thing this skill can
> produce.** A command that looks plausible and silently fails, or passes vacuously,
…

How to install

The exact contents, by fingerprint
mdr add grayma77er/tiny-spec/tiny-spec-adopt@sha256:4c199abc4c5a6cfc

The line at the top of this page pins the label git:20261018.7e4496a, 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.
