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.

Environment config

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.

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

go.sum pins the dependency tree.

Found go.sum

✓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.

go.mod declares a Go version

✓Reproducible environment 2/2

dockerfile gives a known-good environment.

Verification loop 22/22 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

208 test files against 523 source files.

e.g. cmd/info_test.go, internal/client/client_test.go, internal/client/config_test.go

✓Test command is discoverable 7/7

An agent can find and run `make test`.

✓Continuous integration 4/4

4 GitHub Actions workflows define what "passing" means.

✓Lint and format rules 3/3

.golangci.yml encodes the house style.

–Static type checking n/a

Not applicable — the Go compiler type checks every build.

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 3/3

.gitignore covers 28 patterns.

✓File sizes fit in context 6/6

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

✗Repository weight 4/5

About 65.6MB 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 derailed/k9s

# AGENTS.md

🐶 Kubernetes CLI To Manage Your Clusters In Style!

## Setup

```
go mod download
```

## Commands

```
make default
make test      # run the test suite, must pass before any commit
make cover
make build     # produce a build
make imgx
make pushx
```

## Layout

- `internal/` 518 source files
- `cmd/`      4 source files

## Conventions

- Tests live alongside the code they cover, following `cmd/info_test.go`.
- CI defines what passing means. See `.github/workflows/lint.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.
