10/10How quickly anything new can orient itself. Full marks.
Higher is better. Accent marks what is costing you most.
Fix these first
01
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.
02
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.
03
Instruction quality
Worth fixing: it never states a build, test, or run command; has no code blocks.
The full marking
Every deduction below names the file or setting it came from.
Instructions 21/27 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, Copilot instructions
✗Instruction quality
6/12
Real instructions, with gaps.
Worth fixing: it never states a build, test, or run command; has no code blocks.
383 characters, a workable length
uses headings, so an agent can skim it
✓README as an entry point
3/3
README has a clear getting-started section.
Setup 15/18 A-
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
6/6
Commands are declared where an agent will look for them.
Makefile
scripts/ directory
✓Environment config
4/4
.env.example documents what the app needs to run.
✓Pinned runtime version
2/2
The language runtime version is pinned.
Found .python-version
–Reproducible environment
n/a
Not applicable — a library doesn't need a container to be worked on.
Verification loop 19/25 B+
Whether an agent can check its own work. This is the category that most decides whether agent output is trustworthy.
✓Tests exist
8/8
136 test files against 651 source files.
e.g. .agents/skills/hyperframes-creative/references/design-spec.md, .agents/skills/manimgl-best-practices/examples/simple_test.py, .agents/skills/media-use/scripts/lib/manifest.test.mjs
✓Test command is discoverable
7/7
An agent can find and run `make test`.
✓Continuous integration
4/4
1 GitHub Actions workflow 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
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 13/20 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 55 patterns.
✗File sizes fit in context
0/6
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.
ink-theater/examples/mocap-figure/clips.js — 528KB
ink-theater/mocap/clips.js — 528KB
tools/video/video_compose.py — 130KB
✗Repository weight
4/5
About 76.4MB 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 World's first open-source, agentic video production system. 12 production pipelines, 100+ tools, 700+ agent skill and production-knowledge files. Turn your AI coding assistant into a full video production studio. ## Setup ``` pip install -r requirements.txt ``` ## Commands ``` make ensure-venv make venv make setup make install make install-dev make install-gpu ``` ## Layout - `tools/` 168 source files - `tests/` 120 source files - `remotion-composer/` 33 source files - `lib/` 20 source files - `scripts/` 9 source files - `ink-theater/` 8 source files ## Conventions - Tests live alongside the code they cover, following `.agents/skills/hyperframes-creative/references/design-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 - `ink-theater/examples/mocap-figure/clips.js` is 528KB. It will not fit comfortably in context, so read it in parts. - Copy `.env.example` before running anything that needs configuration. - 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.
