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

Fix these first

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.

Pinned runtime version

Add a .nvmrc, .python-version, or equivalent so the agent's toolchain matches yours.

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.

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: CLAUDE.md

✓Instruction quality 12/12

Specific enough that an agent can act on it.

11,899 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 14/18 A-

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

✓Deterministic install 6/6

poetry.lock pins the dependency tree.

Found poetry.lock

✓Discoverable commands 6/6

Commands are declared where an agent will look for them.

Makefile

pyproject.toml scripts

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 0/2

No pinned runtime version.

Add a .nvmrc, .python-version, or equivalent so the agent's toolchain matches yours.

–Reproducible environment n/a

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

Verification loop 24/25 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

328 test files against 1045 source files.

e.g. .github/scripts/infer-component-labels.test.js, .github/scripts/pr-gate-docs-exemption.test.js, .github/scripts/vouch-decision.test.js

✓Test command is discoverable 7/7

An agent can find and run `make test`.

✓Continuous integration 4/4

34 GitHub Actions workflows define what "passing" means.

✓Lint and format rules 3/3

pyproject.toml encodes the house style.

✗Static type checking 2/3

Type checking is configured, but not in strict mode.

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 17/20 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 101 patterns.

✗File sizes fit in context 4/6

3 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.

mem0-ts/src/oss/tests/vector-stores-compat.test.ts — 177KB

mem0/memory/main.py — 166KB

integrations/claude-code-plugin/tests/test_memory_core.py — 160KB

✗Repository weight 4/5

About 65.7MB 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 mem0ai/mem0

# AGENTS.md

The Memory Layer for AI Agents - Drop-in memory infrastructure for AI agents and apps. Context that persists. Built for production.

## Setup

```
poetry install
```

## Commands

```
make install
make install_all
make format        # format
make sort
make lint          # lint
make docs
```

## Layout

- `integrations/` 239 source files
- `mem0-ts/`      227 source files
- `mem0/`         148 source files
- `server/`       128 source files
- `examples/`     115 source files
- `tests/`        104 source files

## Conventions

- Tests live alongside the code they cover, following `.github/scripts/infer-component-labels.test.js`.
- CI defines what passing means. See `.github/workflows/agent-plugins-python-checks.yml`, and keep it green.
- TODO: add the two or three conventions a newcomer always gets wrong here.

## Gotchas

- `mem0-ts/src/oss/tests/vector-stores-compat.test.ts` is 177KB. 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/mem0ai/mem0.md

A draft gets the commands right and stops at the things only a maintainer knows. What a good Python 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.
