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

Fix these first

File sizes fit in context

A single file that fills the context window forces an agent to work from fragments, and it will confidently edit code it never saw. Splitting the worst offenders pays for itself immediately.

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 27/27 A+

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

✓Agent instruction file 12/12

AGENTS.md is present, which is the format the most tools read.

Also found: Copilot instructions

✓Instruction quality 12/12

Specific enough that an agent can act on it.

4,546 characters, a workable length

names the actual commands to run

uses headings, so an agent can skim it

includes copyable code blocks

✓README as an entry point 3/3

README has a clear getting-started section.

Setup 16/18 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 n/a

Not applicable — a library doesn't need a container to be worked on.

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

127 test files against 306 source files.

e.g. .github/testdata/fs/css/test/style2.css, adapter_test.go, addon/retry/config_test.go

✓Test command is discoverable 7/7

An agent can find and run `make test`.

✓Continuous integration 4/4

21 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 13/20 B

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 30 patterns.

✗File sizes fit in context 0/6

5 source files are over 100KB.

A single file that fills the context window forces an agent to work from fragments, and it will confidently edit code it never saw. Splitting the worst offenders pays for itself immediately.

ctx_test.go — 323KB

middleware/cache/cache_test.go — 187KB

router_test.go — 135KB

✗Repository weight 4/5

About 73.9MB 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 gofiber/fiber

# AGENTS.md

⚡️ Express inspired web framework written in Go

## Setup

```
go mod download
```

## Commands

```
make help
make audit
make benchmark
make coverage
make format      # format
make markdown
```

## Layout

- `middleware/` 158 source files
- `internal/`   33 source files
- `binder/`     25 source files
- `client/`     18 source files
- `log/`        7 source files
- `addon/`      4 source files

## Conventions

- Tests live alongside the code they cover, following `.github/testdata/fs/css/test/style2.css`.
- CI defines what passing means. See `.github/workflows/after-release.yml`, and keep it green.
- TODO: add the two or three conventions a newcomer always gets wrong here.

## Gotchas

- `ctx_test.go` is 323KB. It will not fit comfortably in context, so read it in parts.

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.
