Higher is better. Accent marks what is costing you most.
Fix these first
01
Instruction quality
Worth fixing: it's 23k characters, which burns context on every single turn; it never states a build, test, or run command; has no code blocks.
02
Discoverable commands
Declare the handful of commands that matter in package.json scripts, a Makefile, or a justfile. Naming them turns guesswork into a lookup.
03
Deterministic install
Commit the lockfile your package manager generates. Without it, an agent's install and your install are different builds, and 'works on my machine' becomes unfalsifiable.
The full marking
Every deduction below names the file or setting it came from.
Instructions 19/27 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.
✗Instruction quality
4/12
Present but too thin to change an agent's behavior.
Worth fixing: it's 23k characters, which burns context on every single turn; it never states a build, test, or run command; has no code blocks.
uses headings, so an agent can skim it
✓README as an entry point
3/3
README has a clear getting-started section.
Setup 5/20 F
Whether an agent can install the project and get it running without a human.
✗Deterministic install
3/6
Only requirements.txt, which pins loosely at best.
Commit the lockfile your package manager generates. Without it, an agent's install and your install are different builds, and 'works on my machine' becomes unfalsifiable.
✗Discoverable commands
0/6
No declared commands. An agent has to infer how to build and run this from the file tree.
Declare the handful of commands that matter in package.json scripts, a Makefile, or a justfile. Naming them turns guesswork into a lookup.
✗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
0/2
No container or devcontainer definition.
A Dockerfile or devcontainer removes an entire class of 'it won't install' failures.
Verification loop 20/25 A-
Whether an agent can check its own work. This is the category that most decides whether agent output is trustworthy.
✗Tests exist
6/8
115 test files against 793 source files.
e.g. tests-unit/app_test/custom_node_manager_test.py, tests-unit/app_test/database_path_test.py, tests-unit/app_test/frontend_manager_test.py
✓Test command is discoverable
7/7
An agent can find and run `pytest`.
✓Continuous integration
4/4
28 GitHub Actions workflows define what "passing" means.
✓Lint and format rules
3/3
pyproject.toml encodes the house style.
✗Static type checking
0/3
No static type checking.
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 15/20 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 26 patterns.
✗File sizes fit in context
2/6
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.
comfy_api_nodes/apis/__init__.py — 209KB
comfy_api_nodes/nodes_bytedance.py — 160KB
comfy_extras/nodes_mesh_postprocess.py — 146KB
✗Repository weight
4/5
About 95.2MB 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 The most powerful and modular diffusion model GUI, api and backend with a graph/nodes interface. ## Setup ``` pip install -r requirements.txt ``` ## Commands ``` ruff check . # lint ``` ## Layout - `comfy/` 305 source files - `comfy_extras/` 156 source files - `tests-unit/` 102 source files - `comfy_api_nodes/` 86 source files - `app/` 36 source files - `comfy_api/` 36 source files ## Conventions - Tests live alongside the code they cover, following `tests-unit/app_test/custom_node_manager_test.py`. - CI defines what passing means. See `.github/workflows/api-node-template.yml`, and keep it green. - TODO: add the two or three conventions a newcomer always gets wrong here. ## Gotchas - `comfy_api_nodes/apis/__init__.py` is 209KB. It will not fit comfortably in context, so read it in parts. - No lockfile is committed, so an install here may not match what CI produced. --- 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.

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.
