jev-browser-wingman 0.3.2 (superseded by 0.3.3)

Superseded by v0.3.3. 0.3.2 was never published to npm, so the install line below does not work. Two statements below are wrong. The "60% lower median cost" is a prompt-cache artifact; the robust figure is 30% lower total cost. And the tool description already carried a weaker form of the skip-open-page rule. 0.3.3 also fixes two defects in this tag: the press after a fill skipped the confirm gate, and a wait for something to disappear could be skipped.

jev-browser-wingman 0.3.2

This release makes wingman finish nearly every step on its own. In the 0.3.1 benchmark run the agent had to take over a step 7 times across the 34 wingman runs; in this run it was twice, both in a single run of the longest task.

What changed

• A press after a fill no longer asks the decision service. When a fill lands and the next step is a key press (Enter to submit, for example), wingman presses the key itself instead of asking which element to target. This removed all 5 of the todo-app hand-backs from the previous run.
• The agent's step guidance covers an "open the page" step that is already done. The tool text now tells the agent to skip a step that opens the page it is already on, instead of re-sending it and bouncing on low confidence.
• Sign-in state survives a trimmed step list. If the agent signs in during one call and later re-sends only the remaining steps, wingman still treats the sign-in as done instead of asking for it again.
• A "wait until text appears" step that is already satisfied is skipped. If the page already shows the expected text, the step completes immediately instead of waiting anyway.
• The calling agent's benchmark prompts carry the same skip-already-open guidance, matching the tool text.

Benchmark

These are the same 17 tasks as 0.3.0 and 0.3.1: each ran twice with wingman and twice with Playwright alone, for 68 runs.

	wingman 0.3.2	Playwright alone
Runs completed	34 of 34	32 of 34
Median cost per run	$0.075	$0.185
Total cost, 34 runs	$3.75	$5.35
Median time per run	16.0 s	15.5 s

Wingman was cheaper on 16 of 17 tasks and faster on 8. Calls that ended by handing a step back fell from 7 in the 0.3.1 run to 2 (both in one run of the seven-page chain, which still completed). Both Playwright misses were the file-upload task, the same task it missed in both earlier runs.

Wall-clock medians rose on both setups against the previous run (wingman 12.0 s to 16.0 s, Playwright 12.7 s to 15.5 s), so part of that shift is the calling model getting slower rather than wingman. The wingman-side decision work per run stayed roughly constant.

With two runs per task, read the differences as indicative, not statistically established. Costs are token use at list prices, not billing.
