solid SKILL.md skillC

solid from chrisreddington/flight-school is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add chrisreddington/flight-school/solid@git:20260523.deb156a

Pins git:20260523.deb156a in mdr.lock. Pin the fingerprint 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

# SOLID Skill

## Overview

SOLID is Robert C. Martin's five object-oriented design principles. In a
TypeScript codebase like Flight School — which mixes a Next.js API surface,
a Copilot SDK adapter layer, GitHub data fetching, and a streaming UI —
SOLID is mostly a tool for keeping modules **swappable, testable, and
free of hidden coupling**. We don't have deep class hierarchies, but we
do have:

- multiple AI providers behind one interface,
- multiple persistence backends (in-memory dev, Cosmos in production),
- many API routes that share auth + rate-limit + audit concerns, and
- streams generated by very different sources (Copilot SDK, mocks, tests).

SOLID gives us shared vocabulary for when to split a module, when to add
an interface, and when *not* to.

## Authoritative reference

This skill is reference material. **The source of truth for code style,
naming, exports, and module organization is
[`.github/instructions/typescript.instructions.md`](../../instructions/typescript.instructions.md).**

If anything here appears to conflict with that file, the instructions
win. In particular:

- Single Responsibility Functions, module organization, and DRY rules

How to install

The exact contents, by fingerprint
mdr add chrisreddington/flight-school/solid@sha256:30e9b7d19571242c

The line at the top of this page pins the label git:20260523.deb156a, 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.

Starting a new one? Use a template for SKILL.md on mdpantry, which passes every one of these checks and says what to change in it.
