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

Fix these first

Repository weight

Large binaries and vendored trees slow every operation an agent performs. Git LFS or a separate assets repo keeps the working tree navigable.

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.

License

Without a license nobody can safely reuse this, and some tools will refuse to work with it at all.

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.

17,809 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 20/20 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 (prepare, preinstall, build, build:unchecked, build:n8n, build:deploy…)

scripts/ directory

✓Environment config 4/4

.env.local.example documents what the app needs to run.

✓Pinned runtime version 2/2

The language runtime version is pinned.

package.json engines.node >=24.0.0

✓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

9982 test files against 20985 source files.

e.g. .github/actions/ci-filter/__tests__/ci-filter.test.ts, .github/scripts/attest-image-sbom.test.mjs, .github/scripts/branch-replay.test.mjs

✓Test command is discoverable 7/7

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

✓Continuous integration 4/4

96 GitHub Actions workflows define what "passing" means.

✓Lint and format rules 3/3

biome.jsonc encodes the house style.

✗Static type checking 2/3

Type checking is configured, but not in strict mode.

Turn on `"strict": true`. Type errors are the fastest feedback an agent gets, and non-strict mode silently discards most of them.

Context economy 11/20 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 91 patterns.

✗File sizes fit in context 2/6

38 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/frontend/editor-ui/src/app/composables/useCanvasOperations.test.ts — 278KB

packages/@n8n/agents/src/runtime/__tests__/agent-runtime.test.ts — 276KB

packages/nodes-base/nodes/UProc/Json/Tools.ts — 268KB

✗Repository weight 0/5

About 539MB checked out. Large enough that cloning and searching are both slow.

Large binaries and vendored trees slow every operation an agent performs. Git LFS or a separate assets repo keeps the working tree navigable.

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.
