charter SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

charter from sno-ai/sno-station-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add sno-ai/sno-station-skills/charter@git:20261024.24e32d5

Write, revise or review a charter: the one document that tells an executor what to deliver, what is out of bounds, what the owner already decided, and how each success check will be proven. Use when work needs a written brief before someone else does it, or when asked to write, change or check a charter.

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

# charter

A charter is one markdown file that says what to deliver and how everyone will know it was
delivered. A task is named by its charter
filename. `charter` writes it; `deliver` carries a released charter out. Any kind of project
uses it: software, documents, campaigns, research, operations. The owner is whoever owns the
work (often the user); speak to them in the language they use.

Prerequisites: none to use it; its selftest needs bash and python3.

Read `references/template.md` for the file layout and `references/questions.md` before asking
the owner anything.

## Rules that keep a charter useful

- Preserve the owner's words and decisions. Never invent a decision, a fact or a requirement.
  A missing choice that would change the outcome is asked once, one question at a time, at the
  end of a message; independent work continues while it waits, and silence is not approval.
- Read the existing work first (files, documents, data, earlier decisions). Ask nothing they
  already answer.
- Every success check names what will be observed, where, and how, and can be answered pass or
  fail by a real run or inspection. The expected result comes from the requirement or from
…

How to install

The exact contents, by fingerprint

mdr add sno-ai/sno-station-skills/charter@sha256:0e2bbe6b9208d9e0

The line at the top of this page pins the label git:20261024.24e32d5, 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.
