tool-loop

ok

Forces a tool call, feeds the result back, and checks the continuation uses it.

  • step1 (required): multiply({"a":23,"b":17}) → step2: "23 multiplied by 17 is 391."

web-search

ok

Enables server-side web search and checks invocation counts, the per-request cost surcharge, and provider-executed output blocks.

  • Skipped: model does not support the catalog's web_search tool version.
Result
{
  "skipped": "no server-side web search support"
}

reasoning-tool-continuity

ok

Reasoning model: continuity token captured on a tool call and replayed so the follow-up succeeds.

  • Step 1 didn't engage reasoning (adaptive discretion) — signature not exercised this run.
  • reasoned=false, none token —; follow-up → "**Balance for account `acme-42`:** $1,234.00 **Calculation (5% annual"
Result
{
  "signatureType": "none",
  "tokenCaptured": false,
  "reasoned": false,
  "answered": true,
  "continuation": "**Balance for account `acme-42`:** $1,234.00\n\n**Calculation (5% annual compound growth for 7 years):**\n\n\\[\n\\text{Future Balance} = 1234 \\tim"

prompt-cache

ok

Repeat a large prefix; assert cache-read tokens are reported and cost drops.

  • Skipped: provider has no (known) prompt-cache reporting.
Result
{
  "skipped": "cacheStyle=none"
}

json-output

ok

Requests a strict JSON object and checks it parses with the required keys.

  • Output parsed as JSON.
  • All required keys present.
  • Output is bare JSON (no leading prose/fence).
Result
{
  "parsed": {
    "name": "Anthropic",
    "founded": 2021,
    "headquarters": "San Francisco, California, United States"
  },

truncation

streaming-only-rejection

ok

Streaming-only models reject complete(); all others accept it.

  • streamingOnly=false; complete() succeeded.
Result
{
  "streamingOnly": false,
  "completeThrew": false
}

abort

ok

A pre-aborted signal rejects the call (abort is threaded + honored).

  • pre-aborted signal → rejected (AbortError).
Result
{
  "rejected": true,
  "errorName": "AbortError"
}
