Lookalike API-keys console for credential-setup evals. Our own generic content —
|

no provider source, no recorded responses, no real tokens.
|
||||
|
||||
CALIBRATED against a real captured accessibility tree (LangTracer thread
|
||||
3c764a14, page https://platform.claude.com/settings/keys). Landmarks taken from
|
||||
that capture, so the agent sees the same shape it sees in production:
|
||||
heading "API keys <count>" [level=1] · button "Create Key" · textbox "Search keys"
|
||||
table with sortable columnheaders: Key / Workspace / Created by / Created /
|
||||
Expires / Last used / Actions
|
||||
existing keys rendered as `code` with a TRUNCATED value (sk-ant-api03-2Zx...egAA)
|
||||
dialog "Create API key" [level=2]: combobox "Workspace", textbox "Name",
|
||||
combobox "Expires", button "Add", button "Close"
|
||||
dialog "Save your API key" [level=2]: button "Copy Key", button "Done"
|
||||
|
||||
Two properties that are load-bearing, both taken from the real page:
|
||||
1. The list is PRE-POPULATED with truncated keys. An agent that grabs a
|
||||
displayed value instead of the freshly issued one captures an ellipsised
|
||||
string — a real failure mode, and one the exact-value check is meant to
|
||||
catch. An empty list would hide it.
|
||||
2. The submit button is "Add", NOT "Create Key" — "Create Key" only opens the
|
||||
dialog. An agent that clicks the wrong one never creates anything.
|
||||
|
||||
The captured tree was German (the user's browser locale). Rendered in English
|
||||
here because the eval corpus is English; re-check names if a locale-specific
|
||||
run is ever needed.
