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

Fix these first

Instruction quality

Worth fixing: it never states a build, test, or run command; 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.

README as an entry point

Give the README an Install and a Usage heading with real commands under each. Agents pattern-match on those headings.

The full marking

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

Instructions 20/27 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 6/12

Real instructions, with gaps.

Worth fixing: it never states a build, test, or run command; has no code blocks.

455 characters, a workable length

uses headings, so an agent can skim it

✗README as an entry point 2/3

README exists but never explains how to get the thing running.

Give the README an Install and a Usage heading with real commands under each. Agents pattern-match on those headings.

Setup 14/14 A+

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

✓Deterministic install 6/6

pnpm-lock.yaml pins the dependency tree.

Found pnpm-lock.yaml

✓Discoverable commands 6/6

Commands are declared where an agent will look for them.

package.json scripts (clean, test, test:pr, test:ci, test:eslint, test:sherif…)

scripts/ directory

–Environment config n/a

Not applicable — this reads as a library, with no environment to configure.

✓Pinned runtime version 2/2

The language runtime version is pinned.

Found .nvmrc

–Reproducible environment n/a

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

Verification loop 25/25 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

309 test files against 1227 source files.

e.g. packages/angular-query-experimental/src/__tests__/infinite-query-options.test-d.ts, packages/angular-query-experimental/src/__tests__/infinite-query-options.test.ts, packages/angular-query-experimental/src/__tests__/inject-devtools-panel.test.ts

✓Test command is discoverable 7/7

An agent can find and run `npm run test`.

✓Continuous integration 4/4

4 GitHub Actions workflows define what "passing" means.

✓Lint and format rules 3/3

eslint.config.js encodes the house style.

✓Static type checking 3/3

Strict type checking is on, which catches a whole class of agent mistakes before they run.

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 40 patterns.

✗File sizes fit in context 2/6

4 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.

packages/react-query/src/__tests__/useQuery.test.tsx — 183KB

packages/preact-query/src/__tests__/useQuery.test.tsx — 179KB

packages/solid-query/src/__tests__/useQuery.test.tsx — 152KB

✗Repository weight 4/5

About 113.9MB 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.

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.
