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

Fix these first

Instruction quality

Worth fixing: it's under 200 characters, which is closer to a placeholder than instructions; it never states a build, test, or run command; has no headings to structure it; has no code blocks.

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.

Instructions 15/27 B-

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: CLAUDE.md

✗Instruction quality 0/12

Present but too thin to change an agent's behavior.

Worth fixing: it's under 200 characters, which is closer to a placeholder than instructions; it never states a build, test, or run command; has no headings to structure it; has no code blocks.

✓README as an entry point 3/3

README has a clear getting-started section.

Setup 16/20 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

scripts/ directory

✗Environment config 0/4

Nothing documents the environment this needs. An agent will get a runtime error it can't diagnose.

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

.devcontainer.json 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

2395 test files against 5518 source files.

e.g. build/ci/jenkins/pod/chaos-test.yaml, build/ci/jenkins/pod/scale-test.yaml, client/bulkwriter/bulk_import_test.go

✓Test command is discoverable 7/7

An agent can find and run `pytest`.

✓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 11/20 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 88 patterns.

✗File sizes fit in context 0/6

142 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.

internal/http/webui/assets/index-nmS7rbPW.js — 915KB

tests/python_client/milvus_client/test_milvus_client_struct_array_nullable.py — 549KB

internal/mocks/mock_mixcoord_client.go — 512KB

✗Repository weight 2/5

About 355MB checked out. Large enough that cloning and searching are both slow.

Large binaries and vendored trees slow every operation an agent performs. Git LFS or a separate assets repo keeps the working tree navigable.

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 milvus-io/milvus

# AGENTS.md

Milvus is a high-performance, cloud-native vector database built for scalable vector ANN search

## Setup

```
go mod download
```

## Commands

```
make milvus
make build-go
make milvus-gpu
make get-build-deps
make getdeps
make get-proto-deps
```

## Layout

- `internal/` 3811 source files
- `pkg/`      751 source files
- `tests/`    592 source files
- `client/`   201 source files
- `cmd/`      86 source files
- `scripts/`  39 source files

## Conventions

- Tests live alongside the code they cover, following `build/ci/jenkins/pod/chaos-test.yaml`.
- CI defines what passing means. See `.github/workflows/all-contributors.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/http/webui/assets/index-nmS7rbPW.js` is 915KB. It will not fit comfortably in context, so read it in parts.

Drafted by agentreadme.com from what is in this repository. Everything marked TODO
needs a human. Check it in as AGENTS.md at the root.

Open the raw markdown or curl -o AGENTS.md agentreadme.com/draft/milvus-io/milvus.md

A draft gets the commands right and stops at the things only a maintainer knows. What a good Go AGENTS.md looks like covers what to add by hand, and what AGENTS.md is explains the format itself.

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.
