The 1.0s sleep between sequential tool calls has been present since the
initial commit with no documented rationale. It sleeps between local
tool executions — the next LLM request goes out only after the whole
batch — so it rate-limits nothing, and the parallel read-only path
already runs with no delay. Every multi-tool turn pays (N-1) seconds
of dead time. Remove the sleep, the internal tool_delay plumbing, and
dead test assignments. AIAgent.__init__ keeps tool_delay as a
deprecated no-op keyword for one release so existing programmatic
callers construct cleanly; passing it emits a DeprecationWarning.
Locks the contract that a non-retryable failure (a Cloudflare 403
"managed challenge" page) returns a short, HTML-free `error` field —
guarding the field path where the raw page was dumped to Discord as
~31 messages.
The test drives the standard chat-completions path with a concrete
model so the turn actually reaches `client.chat.completions.create`,
where the mocked 403 is raised. It asserts the create call happened
(guarding against a vacuous pass — an empty model on the Codex
Responses path would otherwise abort on a validation ValueError before
any API call) and that the summarized error includes "403" while
excluding <html> / _cf_chl_opt. The non-retryable abort path is
provider-agnostic; a Cloudflare managed-challenge 403 can surface on
any provider behind Cloudflare.
