Higher is better. Accent marks what is costing you most.

Fix these first

Agent instruction file

Add an AGENTS.md at the root: what the project is, how to install, how to run, how to test, and the two or three conventions a newcomer always gets wrong.

Instruction quality

Instructions earn their keep by naming exact commands. 'Run the tests with `pnpm test`' beats three paragraphs of philosophy.

Static type checking

A type checker gives an agent an error message instead of a runtime surprise. It's the second-fastest feedback loop after the compiler.

The full marking

Every deduction below names the file or setting it came from.

Instructions 3/27 F

Whether the repo tells an agent how to behave before it starts guessing.

✗Agent instruction file 0/12

None found. Every agent that opens this repo starts from zero.

Add an AGENTS.md at the root: what the project is, how to install, how to run, how to test, and the two or three conventions a newcomer always gets wrong.

Looked for AGENTS.md, CLAUDE.md, .github/copilot-instructions.md, .cursorrules

✗Instruction quality 0/12

Nothing to judge, since there are no instructions.

Instructions earn their keep by naming exact commands. 'Run the tests with `pnpm test`' beats three paragraphs of philosophy.

✓README as an entry point 3/3

README has a clear getting-started section.

Setup 18/20 A

Whether an agent can install the project and get it running without a human.

✓Deterministic install 6/6

gemfile.lock pins the dependency tree.

Found gemfile.lock

✓Discoverable commands 6/6

Commands are declared where an agent will look for them.

Makefile

✗Environment config 2/4

Env vars are mentioned in the README but there's no example file to copy.

Add a .env.example listing every variable with a safe placeholder value. It's the cheapest possible fix and it unblocks the whole first run.

✓Pinned runtime version 2/2

The language runtime version is pinned.

Found .ruby-version

✓Reproducible environment 2/2

dockerfile gives a known-good environment.

Verification loop 22/25 A

Whether an agent can check its own work. This is the category that most decides whether agent output is trustworthy.

✓Tests exist 8/8

27 test files against 28 source files.

e.g. spec/async_spec.rb, spec/integrations/auto_cd_spec.rb, spec/integrations/bracketed_paste_magic_spec.rb

✓Test command is discoverable 7/7

An agent can find and run `make test`.

✓Continuous integration 4/4

1 GitHub Actions workflow define what "passing" means.

✓Lint and format rules 3/3

.rubocop.yml encodes the house style.

✗Static type checking 0/3

No static type checking.

A type checker gives an agent an error message instead of a runtime surprise. It's the second-fastest feedback loop after the compiler.

Context economy 19/20 A+

Whether the repo fits in a context window, or fights it.

✓No committed build output 6/6

No generated directories committed.

✗.gitignore hygiene 2/3

.gitignore has only 1 rules.

Start from a standard template for your stack. It prevents the previous problem before it happens.

✓File sizes fit in context 6/6

No source file is large enough to crowd out a context window.

✓Repository weight 5/5

About 583KB checked out, which is comfortable.

Here is your AGENTS.md

Drafted from what is actually in this repository: the install command from your lockfile, the commands you already declare, your real directory layout. Anything marked TODO needs a person. Save it at the root as AGENTS.md.

AGENTS.md — drafted for zsh-users/zsh-autosuggestions

# AGENTS.md

Fish-like autosuggestions for zsh

## Setup

```
bundle install
```

## Commands

```
make clean
make test    # run the test suite, must pass before any commit
```

## Layout

- `spec/` 27 source files

## Conventions

- Tests live alongside the code they cover, following `spec/async_spec.rb`.
- CI defines what passing means. See `.github/workflows/integration.yml`, and keep it green.
- TODO: add the two or three conventions a newcomer always gets wrong here.

Think this mark is wrong?

Every deduction above names the file it came from, so this can be settled by looking. If a check missed something, that is a rule worth fixing.
