Use whenever you are writing, reviewing, or refactoring TypeScript/TSX in this repo. Enforces the project's readability contract: self-documenting names, plain control flow, and comments that explain *why* not *what*. Trigger phrases: "clean this up", "make this readable", "refactor", "name this better", "is this code clear?", "review my code".

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

# Readable Code skill

> A reader who has **never seen this codebase before** should be able to open
> any file and understand what it does without external context.
> That is the bar. Everything in this skill exists to defend it.

This skill is the practical companion to the readability rules. The
authoritative rules live in:

- [`.github/instructions/typescript.instructions.md`](../../instructions/typescript.instructions.md) — naming, anti-patterns, validation gates.
- [`.github/instructions/documentation.instructions.md`](../../instructions/documentation.instructions.md) — TSDoc proportionality, inline-comment standards.

This file is the **how to apply them** layer.

## The four rules

### Rule 1 — Names carry the meaning

The variable, function, and type name must tell you what it is **without
reading the implementation**. If you have to scan three lines to figure out
what `data` holds, the name is wrong.

```typescript
// ❌ Generic names force readers to trace data flow
const data = await fetch(url).then(r => r.json());
const result = data.items.filter(i => i.x > 0);

// ✅ Names answer "what is this?"
const profileResponse = await fetch(url).then(r => r.json());
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add chrisreddington/flight-school/readable-code@sha256:81d949c0192918b0

The line at the top of this page pins the label git:20260524.32ea246, 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.
