Karpathy's jagged questions — the 50 m car wash

measures: a solution of yours, bound to this task version · intent=existing_solution

tp clones the solution at its pinned commit and runs it with your provider key against the pinned task version, and progress mirrors privately to your account. The site does not grade this path: the CLI runs the task's judge locally and uploads the result, which every board marks self-reported. Reading this page creates nothing. Needs the pinned tp build (0.0.15.dev23 or newer; PyPI's 0.0.14 has no --server).

what to do

WHAT THIS LINK MEASURES: the recorded solution "car-wash-claude-sonnet-5" at its pinned commit (intent=existing_solution). Do not answer the cases yourself.

Reproduce the trapstreet solution "car-wash-claude-sonnet-5" on the task "Karpathy's jagged questions — the 50 m car wash" and report it to https://trapstreet.run.

The solution is pinned to git+https://github.com/xiaotianhan91/karpathys-jagged-solutions@c128ecb2da2189f1f259e3d2538fcc17e4523049#subdirectory=claude-sonnet-5; the task is pinned to https://github.com/xiaotianhan91/karpathys-jagged-questions at e13950d4882019936d16c6cf7b756b4d4fc68274 — task version tkv_gc2ev1a02159oyr6, the one its recorded runs used; the recorded run used tp 0.0.10.dev1+g02798c7.d20260727.

Run exactly:

    tp run git+https://github.com/xiaotianhan91/karpathys-jagged-solutions@c128ecb2da2189f1f259e3d2538fcc17e4523049#subdirectory=claude-sonnet-5 --server https://trapstreet.run --trust-remote --allow-unanchored

If the solution's trap.yaml binds more than one task, add --task <alias> where <alias> is the trap.yaml key whose `source` points at https://github.com/xiaotianhan91/karpathys-jagged-questions@e13950d4882019936d16c6cf7b756b4d4fc68274 — the alias is the author's key, not this site's task id; the site resolves the board from the pinned task, not from the alias. The site does not grade this run: the CLI runs the task's judge locally against the pinned version and uploads the result, which every board marks self-reported. If tp is missing, or `tp run --help` shows no --server flag: uv tool install --force "git+https://github.com/trapstreet/trap@7729f718a9c660cf5a20677de495453d4528dcc0" (PyPI's trap-cli 0.0.14 predates --server, live progress and site grading; this server needs 0.0.15.dev23 or newer and will say so with HTTP 426). If it has never been paired with this server: open https://trapstreet.run/cli/authorize, copy the token, then tp auth login --with-token --server https://trapstreet.run — pairing is once, not per run. --server is not optional: without it tp resolves the DEFAULT server, finds no credential for it, and runs with sync silently off. The run prints its URL before the first case — give me that URL. Do not tp submit; that is a separate step I will ask for.

the line that brought you here

Reproduce the trapstreet solution "car-wash-claude-sonnet-5" on "Karpathy's jagged questions — the 50 m car wash" (intent=existing_solution): open https://trapstreet.run/launch/solution/sol_0krla39vv68odt4b?version=tkv_gc2ev1a02159oyr6 and follow it exactly — it is pinned to that solution commit and that task version; use my paired tp with --server. Give me the run URL it produces; do not submit.

Runs stay off the board until their owner publishes them; publishing is a separate action on the run page, and nothing on this page publishes anything. A run opened with an account is private to that account. A run opened without one can be watched by anyone holding its link until it is saved — saving takes the link’s one-time code.
