# Suite C — 27 multi-step browser tasks on held-out real websites

A small live benchmark for web agents: **27 tasks on 27 real sites**, 19 of them needing 4 or more actions (search, then
filters, sort, pagination, opening the right result). Every task has a **programmatic success check** on the final page
(URL parameters, title, visible text or observed form state), so no LLM judge is needed.

Built to evaluate [cklxx/laya-browser](https://huggingface.co/cklxx/laya-browser): none of these domains appears in any of its
training sources (checked at start-up against the training domain list).

## Tasks

`tasks.jsonl`, one row per task:

```
name               e.g. "wp-cache-commercial-redis"
start_url          where the agent starts
goal               "Search the plugin directory for 'cache', show only commercial plugins, and open the 'Redis Object Cache' plugin."
scripted_steps     the length / shape of a scripted solution ("4: fill, Enter, filter, link")
check_description  what success means ("URL /plugins/redis-cache")
check_python       the exact check: lambda u, t, x, a: ...   (u = final URL, t = title, x = visible text, a = observed actions)
setup              optional pre-run hook (clear_storage: the site's localStorage is cleared first)
```

## Validation

Every task was validated with a **model-free scripted solution** (observe → pick the action by label → act): a task was
kept only if the script passed its check 3/3 on separate runs **and** the check failed on the start page (doing nothing
cannot pass). The judge scrolls the whole final page before checking, so results do not depend on where the agent left the
scroll position. Runner and scripts: `code/apps/browser_suite_c.py`, `code/apps/suite_c_scripts.py`, `code/apps/SUITE_C.md`
in [cklxx/laya-browser](https://huggingface.co/cklxx/laya-browser).

## Results

| agent | passed (27 tasks × 2 runs) |
|---|---|
| laya-browser v17s (322M, one forward pass per step) | 2 / 54 |
| laya-browser v19s | 11–14 / 54 (two ×2 runs) |

`results/` has v19s's per-task results and full step traces. Live sites change and load at different speeds: a single run
varies by about ±4 tasks, so repeat runs before comparing agents.
