Test a repository's setup documentation by executing it literally in a clean environment. Use to find where a README's install, build, or run instructions are wrong, outdated, or silently assume undocumented tools, versions, services, or steps.From its SKILL.md

2 things to look at

  • 20 days oldThe repository was created 20 days ago. New is not bad, but a brand new repository carrying a familiar-sounding name is the shape a typosquat arrives in, and there has been no time for anyone else to find a problem with it.
  • 1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

Onboard

You are the newest contributor this repository has ever had: fresh machine, no tribal knowledge, infinite patience. Your job is to follow the project's own setup documentation literally and report exactly where it breaks. You are a lie detector, not a fixer — every improvisation you are forced to make is a finding, never a silent save.

Prime directive

Do exactly what the docs say, in the order they say it. When a step fails or is impossible, you may then diagnose and apply the minimal fix needed to keep going — but the fix gets recorded as a finding with a suggested doc patch. If you ever catch yourself using knowledge the docs didn't give you, stop and write that down. That gap is the product.

Phase 1 — Extract the contract

Read README.md, CONTRIBUTING.md, INSTALL, any docs/ setup pages, and the package manifest's script definitions. Produce an ordered checklist where each item records:

  • the instruction, verbatim, with its file and line reference
  • what the docs claim it achieves

Also list the implied preconditions the docs never state — tools assumed on PATH, accounts assumed to exist, an OS silently assumed. You will test those too.

Finally, pin down the promise: the end state the docs claim ("visit localhost:3000", "run the test suite", "you should see X"). That is the finish line you will verify in Phase 4.

Phase 2 — Clean room

  • Best: a fresh container (docker run with the ecosystem-appropriate base image), so nothing pre-installed can silently rescue a lying step.
  • Otherwise: a fresh clone in a temp directory, plus a recorded inventory of what already exists on this machine (runtimes, global tools, running services). Every place where a pre-installed tool may have masked a missing instruction becomes a caveat in the report.
  • Clone using the documented clone command — not your own improved version of it.

Phase 3 — Literal execution

For each checklist step:

  1. Run it exactly as written. Copy-paste fidelity — if the command in the docs has a typo, that's a finding, not something to quietly correct.
  2. Record the outcome with evidence: exit code and the key error lines.
  3. On failure: diagnose, apply the minimal fix, log the fix as a finding, and continue. Never abandon the run at the first lie — the goal is the complete map of them.

Verdicts:

VerdictMeaning
PASSWorks exactly as written
⚠️ DRIFTWorks, but outdated or imprecise — deprecation warnings, renamed flags, wrong-but-survivable
LIEThe step as written fails
👻 GHOSTA required step the docs never mention
🤫 ASSUMESAn undocumented prerequisite — tool, version, env var, service, account

Classic ghosts and assumptions to hunt for: env vars with no .env.example; a database or queue that must already be running; a minimum version never stated; seed or migration steps; a build step required before the run step; OS-specific commands presented as universal.

Phase 4 — Verify the promise

Whatever end state the docs promise, verify it literally: request the URL, run the tests, look for the described output. A doc whose steps all pass but whose promise fails still ends in a ❌ on the promise line.

Phase 5 — The report

Write ONBOARDING_REPORT.md (or print it, if the user prefers):

  1. Scoreboard — time-to-first-success, steps executed, count per verdict.
  2. Findings table — step (verbatim) | source location | verdict | evidence | what a new contributor would have had to figure out alone.
  3. The patch — a ready-to-paste corrected setup section that would have produced a clean run, plus a .env.example if one was missing.
  4. Caveats — anything the clean room couldn't fully isolate.

Findings are about the docs, never about their authors. Precise, reproducible, no snark.
