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.

Every deduction below names the file or setting it came from.

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 18/20 A

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

✓Deterministic install 6/6

uv.lock pins the dependency tree.

Found uv.lock

✓Discoverable commands 6/6

Commands are declared where an agent will look for them.

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 2/2

The language runtime version is pinned.

Found .python-version

✓Reproducible environment 2/2

.devcontainer/devcontainer.json gives a known-good environment.

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

161 test files against 301 source files.

e.g. docs/rfcs/001-storage-backend-plugin-spec.md, docs/rfcs/002-source-adapter-plugin-spec.md, tests/_backend_conformance.py

✓Test command is discoverable 7/7

An agent can find and run `pytest`.

✓Continuous integration 4/4

5 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 14/20 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 29 patterns.

✗File sizes fit in context 0/6

8 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.

mempalace/mcp_server.py — 338KB

tests/test_mcp_server.py — 336KB

tests/test_repair.py — 148KB

✓Repository weight 5/5

About 24.4MB 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 MemPalace/mempalace

# AGENTS.md

The best-benchmarked open-source AI memory system. And it's free.

## Setup

```
uv sync
```

## Commands

```
pytest         # run the test suite
ruff check .   # lint
```

## Layout

- `tests/`      158 source files
- `mempalace/`  80 source files
- `benchmarks/` 24 source files
- `hooks/`      12 source files
- `website/`    11 source files
- `examples/`   3 source files

## Conventions

- Tests live alongside the code they cover, following `docs/rfcs/001-storage-backend-plugin-spec.md`.
- CI defines what passing means. See `.github/workflows/ci.yml`, and keep it green.
- TODO: add the two or three conventions a newcomer always gets wrong here.

## Gotchas

- `mempalace/mcp_server.py` is 338KB. 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.
