Readiness lenses

The same repo, two ways: how ready it is for an AI coding agent, and for a human newcomer. Switch lenses to see each one's score and checks.

How ready the repo is for an AI coding agent to read, build, and operate it.

21 of 34 checks passed across 6 categories.

  • Machine Orientation

    3 checks passed4 problems found

    • mediumAgent instructions file

      AGENTS.md / CLAUDE.md is the direct, machine-read channel for entry points and conventions.

      Fix: Add an AGENTS.md naming the entry points, the build/test commands, and the house conventions.

    • lowllms.txt present

      An llms.txt is the emerging machine-orientation standard — a curated map for LLMs.

      Fix: Add an llms.txt pointing at the key docs and entry points.

    • lowTopics set

      GitHub topics situate the repo's domain and stack for an agent at a glance.

      Fix: Add a few GitHub topics describing the domain and stack.

    • lowArchitecture doc

      An ARCHITECTURE doc hands an agent the module map instead of making it infer one.

      Fix: Add an ARCHITECTURE.md describing the major components and how they fit.

    • README present — An agent reconstructs what the repo is and how to work in it from the README first.
    • Repository description set — The one-line description is the fastest orientation signal an agent reads.
    • Contribution conventions are written down — A contributor guide is where an agent learns the branch, commit, and review conventions it must follow.
  • Reproducible Setup

    3 checks passed3 problems found

    • mediumContainer or dev-container

      A Dockerfile / compose / devcontainer removes 'works on my machine' from setup.

      Fix: Add a Dockerfile, a compose file, or a .devcontainer so the environment is declared, not assumed.

    • lowEnv template present

      A .env.example tells an agent which configuration keys it must supply to run.

      Fix: Ship a .env.example listing every required key with placeholder values.

    • lowDev container

      A .devcontainer gives an agent a one-command, fully-declared environment.

      Fix: Add a .devcontainer so the toolchain is declared, not assumed.

    • Lockfile committed — Without a lockfile two clones can resolve different dependency trees — the build isn't reproducible.
    • Runtime / toolchain pinned — An unpinned runtime makes an agent guess the version a clean environment needs.
    • Version pins are exact — A floating pin (a bare major, or a range) still drifts between installs.
  • Code Navigability

    2 checks passed0 problems found

    • Conventional source layout — A recognised src/ · lib/ · app/ layout lets an agent localise code without spelunking.
    • TypeScript strict mode on — Strict typing gives an agent typed signatures to anchor an edit on, not guesses.
  • Verification Surface

    5 checks passed2 problems found

    • lowTask runner present

      A Makefile / Taskfile / justfile gives an agent a single index of the project's commands.

      Fix: Add a Makefile / Taskfile / justfile collecting the common commands.

    • lowTypecheck command

      A typecheck script lets an agent catch type errors before they ship.

      Fix: Add a `typecheck` script (e.g. `tsc --noEmit`).

    • Tests present — Runnable tests are the ground truth an agent checks its own edits against.
    • Test command defined — A `test` script is the documented, discoverable way to run the suite.
    • Lint command defined — A linter an agent can run catches a class of mistakes before they ship.
    • CI configured — Readable CI is the feedback loop an agent reads to know what 'green' means here.
    • Build command — A documented build command is the discoverable way for an agent to produce artifacts.
  • Agent Safety

    5 checks passed3 problems found

    • medium.gitignore covers env files

      An ignore rule for .env is what keeps the next careless commit from leaking secrets.

      Fix: Add `.env` (and `.env.*`) to .gitignore.

    • lowCODEOWNERS present

      CODEOWNERS marks the 'don't touch without review' zones an agent should respect.

      Fix: Add a CODEOWNERS file marking the sensitive paths.

    • lowAutomated dependency updates

      Dependabot / Renovate keeps dependencies patched without a human in the loop.

      Fix: Enable Dependabot or Renovate.

    • No committed .env — A tracked real .env hands secrets to anything — including an agent — that reads the repo.
    • No exposed secrets — Secret-shaped literals in tracked files are a live credential leak.
    • .gitignore present — A .gitignore is the first guard against an agent committing secrets or build junk.
    • Security policy — A SECURITY.md is where an autonomous security agent reads this repo's rules before acting on it.
    • License makes the code reusable — Without a license an agent cannot safely copy, redistribute, or vendor any of this code.
  • Context Economy

    3 checks passed1 problem found

    • lowGenerated / vendored files marked

      A .gitattributes linguist marker tells tools (and agents) what to skip.

      Fix: Mark generated/vendored paths in .gitattributes (linguist-generated / linguist-vendored).

    • Dependencies not vendored in — A committed node_modules / vendor tree drowns the real signal an agent needs.
    • Build output not committed — Generated dist/ · build/ output is noise an agent has to read past.
    • No oversized source file — A single file in the hundreds of KB blows past an agent's effective context window.

Where the grip slips

  1. highGetting Running+15 pts if fixed

    No DEVELOPMENT.md or setup guide—README defers all setup to external docs

    A newcomer cloning the repo sees only 'follow vuejs.org docs' and no indication of how to install, build, or test locally. The package.json reveals pnpm, Node 20+, and build scripts, but no entry-level path is documented in the repository itself. This forces every new contributor to hunt for setup instructions or ask for help.

    Fix: Add DEVELOPMENT.md (or expand README with a 'Local Development' section) documenting: (1) prerequisites (Node 20+, pnpm 11.5.2+), (2) install (pnpm install), (3) build (npm run build), (4) test (npm run test), (5) dev server (npm run dev), with copy-pasteable commands. Reference .github/contributing.md for deeper workflows.

  2. highFinding Your Way+12 pts if fixed

    No ARCHITECTURE.md—mental map of 80+ packages unclear to newcomers

    The monorepo contains compiler-core, compiler-dom, compiler-sfc, reactivity, runtime-core, runtime-dom, server-renderer, and many more. No document explains how they relate, what data flows from compiler to runtime, or where to start reading the code. A newcomer cannot distinguish between which packages are public API vs. internals or understand the dependency graph.

    Fix: Create ARCHITECTURE.md with: (1) high-level diagram of compiler → runtime → DOM flow, (2) one-line descriptions of each core package (compiler-core, reactivity, runtime-core, etc.), (3) which packages are public vs. private, (4) how to navigate from a user question to the right module. Link from README and CONTRIBUTING.md.

  3. mediumFirst Impression+8 pts if fixed

    README lacks a working code example—feels abstract for newcomers

    The README explains nothing about what you can *do* with Vue by running the code in this repository. No example of compiling a component, using reactivity, or running a minimal project. It reads as 'this is important' rather than 'here's what you get.'

    Fix: Add a 'Quick Example' section to README showing: (1) a minimal .vue component, (2) one line showing how to compile or run it from this repo (e.g., `npm run build && npm run dev`), (3) what output or behavior to expect. This gives newcomers immediate proof of what the repo does.

  4. mediumPath To Contribute+8 pts if fixed

    Contributing guide not visible in snapshot; unclear contribution workflow for beginners

    The README references 'Contributing Guide' at .github/contributing.md, but the snapshot does not show its content. Without seeing it, a newcomer cannot verify that the guide is beginner-friendly, includes examples, or labels 'good first issues.'

    Fix: Verify .github/contributing.md includes: (1) step-by-step PR workflow (fork → branch → commit → PR), (2) commit message conventions with examples (link to .github/commit-convention.md), (3) test and lint commands (npm run test, npm run lint), (4) link to ARCHITECTURE.md for code navigation. If not, expand it.

  5. lowPath To Contribute+6 pts if fixed

    No 'good first issue' labels or beginner task list visible

    With 983 open issues, a newcomer has no signal for which issues are suitable for a first contribution. Many might be advanced compiler internals or edge cases.

    Fix: Add 'good-first-issue' or 'beginner-friendly' labels to 5–10 small, well-scoped issues (e.g., doc fixes, small refactors, test coverage). Curate a list in CONTRIBUTING.md under 'Getting Started' pointing to these labels. GitHub's built-in tooling (https://github.com/vuejs/core/contribute) will then highlight them.

  6. mediumOpen Door+5 pts if fixed

    No CODE_OF_CONDUCT.md—missing explicit social safety signal for large project

    With 53k+ stars and hundreds of contributors, the absence of a visible code of conduct is a red flag for inclusive projects. Newcomers may hesitate to ask questions or report issues if there's no stated community standard.

    Fix: Add CODE_OF_CONDUCT.md (e.g., based on Contributor Covenant) to the repository root. Link it from the main README and .github/contributing.md. This is table-stakes for projects of this scale.

  7. lowGetting Running+5 pts if fixed

    Scripts in package.json lack inline documentation—npm run dev doesn't say what it does

    Scripts like 'npm run dev', 'npm run build-dts', 'npm run dev-sfc' are terse and undocumented. A newcomer has no idea what 'dev-sfc-prepare' vs. 'dev-sfc-run' means or why they would use one over the other.

    Fix: Add a 'scripts' section to DEVELOPMENT.md listing each npm script with a one-line description: 'npm run dev — start dev server for core, 'npm run test — run unit tests with vitest', etc. Or use a tool like ntl (npm task list) to make scripts self-documenting.
