# AGENTS.md

Instructions for coding agents working in this repository. People should read

[CONTRIBUTING.md](CONTRIBUTING.md); this file is the short version of it.

## Layout

- `skills/measured-type/`: the skill (SKILL.md, `references/`) and its tools

(`scripts/`, tests in `scripts/test/`). Run commands from here.

- `specs/`: one numbered spec per change, with requirement IDs.

- `evals/`: eval cases, graders, analysis scripts and committed results.

## Commands

```bash

cd skills/measured-type

npm install && npx playwright install chromium # once

npm test # the whole suite

node --test scripts/test/<name>.test.js # one file

```

+ From the repository root, `npm run gate` runs the prose check and every test;

+ it is what "done" is checked against.

Set `MT_PYTHON` to a Python that has fontTools, or four tests skip.

## Rules

- **Test first.** Add the requirement to a spec in `specs/`, write the test

named with its ID, watch it fail, then change the code. Run the whole suite

before you say a change works.

- **Never approve what was not computed.** A check that cannot run reports

under Not verified; it never passes in silence.

- **Do not edit anything under `evals/results/`** except to add a new

experiment. Do not change a grader after the runs it grades.

- **Do not touch `.github/brand/`** or the license files.

- **Claims need evidence.** Every rule, number and statement in SKILL.md and

`references/` is either measured by a script or cited (Bringhurst section,

WCAG criterion, specification URL). Paraphrase sources; do not paste them.

- **Style for prose:** no em dashes, no middle dots, no comma before the "and"

or "or" that ends a list, British spelling outside code.

## Done means

- `npm test` passes from `skills/measured-type/` with nothing skipped that was

+ `npm run gate` passes from the repository root with nothing skipped that was

not skipped before, and the change, its spec and its tests are in one commit.
