Higher is better. Accent marks what is costing you most.
Fix these first
01
Agent instruction file
Add an AGENTS.md at the root: what the project is, how to install, how to run, how to test, and the two or three conventions a newcomer always gets wrong.
02
Instruction quality
Instructions earn their keep by naming exact commands. 'Run the tests with `pnpm test`' beats three paragraphs of philosophy.
03
Tests exist
This is the single highest-leverage change on this page. Agents don't need full coverage, they need one command that goes red when they break something. Even a handful of tests on the core path converts blind editing into a feedback loop.
The full marking
Every deduction below names the file or setting it came from.
Instructions 2/27 F
Whether the repo tells an agent how to behave before it starts guessing.
✗Agent instruction file
0/12
None found. Every agent that opens this repo starts from zero.
Add an AGENTS.md at the root: what the project is, how to install, how to run, how to test, and the two or three conventions a newcomer always gets wrong.
Looked for AGENTS.md, CLAUDE.md, .github/copilot-instructions.md, .cursorrules
✗Instruction quality
0/12
Nothing to judge, since there are no instructions.
Instructions earn their keep by naming exact commands. 'Run the tests with `pnpm test`' beats three paragraphs of philosophy.
✗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 12/14 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 (format, sync:content-to-repo, sync:repo-to-database, cleanup:orphaned-content)
scripts/ directory
–Environment config
n/a
Not applicable — this reads as a library, with no environment to configure.
✗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
n/a
Not applicable — a library doesn't need a container to be worked on.
Verification loop 7/25 F
Whether an agent can check its own work. This is the category that most decides whether agent output is trustworthy.
✗Tests exist
0/8
No test files found. An agent has no way to know whether its change broke anything.
This is the single highest-leverage change on this page. Agents don't need full coverage, they need one command that goes red when they break something. Even a handful of tests on the core path converts blind editing into a feedback loop.
✗Test command is discoverable
0/7
There's no obvious way to run the tests. Even if tests exist, an agent won't reliably find the entry point.
Add a `test` script or a `test` target that runs the whole suite with no arguments. The convention is the interface — an agent tries `npm test` and `make test` before it tries reading your CI config.
✓Continuous integration
4/4
8 GitHub Actions workflows 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
3/3
Strict type checking is on, which catches a whole class of agent mistakes before they run.
Context economy 17/20 A
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 11 patterns.
✓File sizes fit in context
6/6
No source file is large enough to crowd out a context window.
✗Repository weight
2/5
About 363MB 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.
# AGENTS.md Interactive roadmaps, guides and other educational content to help developers grow in their careers. ## Setup ``` pnpm install ``` ## Commands ``` pnpm format # format pnpm sync:content-to-repo pnpm sync:repo-to-database pnpm cleanup:orphaned-content ``` ## Layout - `scripts/` 8 source files ## Conventions - There are no tests yet. An agent has no way to check its own work here. - TypeScript runs in strict mode. Type errors are the fastest feedback available, so do not weaken it. - CI defines what passing means. See `.github/workflows/aws-costs.yml`, and keep it green. - TODO: add the two or three conventions a newcomer always gets wrong here. --- 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.
