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.

Lint and format rules

A formatter config is the cheapest way to stop reviewing whitespace in agent diffs. It moves style from opinion to a command.

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 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

scripts/ directory

✗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 19/22 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

242 test files against 1284 source files.

e.g. client/src/__tests__/checkRedirect.test.ts, client/src/__tests__/checkStatus.test.ts, client/src/__tests__/fetchRequest.test.ts

✓Test command is discoverable 7/7

An agent can find and run `make test`.

✓Continuous integration 4/4

3 GitHub Actions workflows define what "passing" means.

✗Lint and format rules 0/3

No linter or formatter config. Style is tribal knowledge, so agent output will drift from yours.

A formatter config is the cheapest way to stop reviewing whitespace in agent diffs. It moves style from opinion to a command.

–Static type checking n/a

Not applicable — the Go compiler type checks every build.

Context economy 18/20 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 32 patterns.

✗File sizes fit in context 4/6

1 source file is 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.

internal/filtering/servicelist.go — 238KB

✓Repository weight 5/5

About 31.6MB 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 AdguardTeam/AdGuardHome

# AGENTS.md

Network-wide ads & trackers blocking DNS server

## Setup

```
go mod download
```

## Commands

```
make build         # produce a build
make init
make quick-build
make deps
make lint          # lint
make test          # run the test suite, must pass before any commit
```

## Layout

- `client_v2/` 584 source files
- `internal/`  445 source files
- `client/`    225 source files
- `scripts/`   26 source files
- `snap/`      1 source file

## Conventions

- Tests live alongside the code they cover, following `client/src/__tests__/checkRedirect.test.ts`.
- CI defines what passing means. See `.github/workflows/mirror.yaml`, and keep it green.
- TODO: add the two or three conventions a newcomer always gets wrong here.

## Gotchas

- Generated output is committed (`build/`). Search will return the compiled copy, so edit the source, not that.
- `internal/filtering/servicelist.go` is 238KB. 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.
