arch-benchmark-browser skillA
arch-benchmark-browser is agent-read markdown (skill) from baristaze/swe_guidelines: Run the benchmark prompt in the chatgpt.com, claude.ai, and gemini.google.com products, signed in, and save each answer with its conversation URL as proof..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# arch-benchmark-browser
Ask three products the same question and keep the answers with their
proof. The prompt, the contract, the size map, and the schema live at
`${CLAUDE_SKILL_DIR}/../../benchmark/browser/` and
`${CLAUDE_SKILL_DIR}/../../benchmark/schema/browser-session.schema.json`.
If any is missing, stop and say the installation is incomplete.
## Input
`$ARGUMENTS` names two sizes, `model=<size> effort=<size>`, each one of
`xs`, `s`, `m`, `l`, `xl`. When one is missing, it is `m`. It may also
name a subset of sites (`sites=claude.ai,gemini.google.com`); the
default is all three.
## What the pages are like
Facts that decide how the steps below go. Read them before the browser.
- The read tools are permitted per domain, and not as a set. On some
domains `get_page_text` and `read_page` are refused while a
screenshot works; on others `find` is refused while `read_page`
works. When a read tool is refused, use a screenshot and `zoom`, and
transcribe from it. Say in the output which site was read that way.
- The composers on chatgpt.com and claude.ai are rich text: a line that
starts with a dash and a space becomes a bullet and the next line gets one too, and

How to install
mdr add baristaze/swe_guidelines/arch-benchmark-browser@git:20260922.28cefc1mdr add baristaze/swe_guidelines/arch-benchmark-browser@sha256:ca9c771b497b27b3Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
