System cards

What a system card is here

A system card describes one configuration of the FlowFinds commerce agent — the agent code, the tool layer and one model behind it — in terms of what has been measured about it rather than what it is meant to do. Every card on this page has the same five sections, and each section is filled from the recorded runs at build time. A card cannot claim a capability that no run exercised, and it cannot omit a failure that a run recorded.

1. Capabilities evaluated. Which scenario groups the configuration was actually put to, and how many cases in each.
2. Evaluations. The recorded outcomes, with dates and the model identifiers the provider resolved.
3. Limitations. What the evidence does not cover.
4. Failure modes. The categories of failure observed, with the recorded evidence for each.
5. Safe-use guidance. What follows from the above for someone deciding how much authority to give the agent.

These are development cards, not release cards. They describe an agent under active tuning, on 51 scored cases in total. Read them alongside the commerce-v1 methodology, which sets out how the evidence was produced.

Failure modes observed across every configuration

The categories below are derived from the failure text the runner recorded, not from hand-written examples. They are published because a failure mode is the most useful thing a card can tell an operator: it says where not to trust the system yet.

Guard rails that fired

Separately from model failures, the tool layer refuses to compute on inputs that do not support a conclusion. These refusals are a designed behaviour and are recorded alongside the case, because how the agent responds to a refusal is itself part of what is being measured.

• economics — 2 refusals.
  • Error: The supplied amounts mix tax-inclusive and tax-exclusive bases. Ask for amounts on one consistent tax basis; do not calculate profit or CPA from these values.
  • Error: landed_cost was not supplied in the quoted inputs; use null for an unknown cost.
• supplier_order — 1 refusal.
  • Error: Supply one complete, verbatim founder message containing the supplier terms.

Cards

4 configurations have recorded runs. A configuration appears here as soon as one run exists for it, however it went.

openai · gpt-5.5

7 recorded runs, 18 scored cases, all on 2026-09-05. The transport reported no resolved model identifier, so the requested name is all that is recorded.

Capabilities evaluated

Evaluations

Aggregate pass rate 77.8% over 18 cases. Median case time 23.6 s. 2 cases returned no valid final answer. The run-by-run detail is on the results page.

Limitations

• Sample size: 18 cases across 7 runs, each case attempted once per run. No variance estimate is available and none is offered.
• Every scenario is synthetic and single-turn. Nothing here evaluates multi-turn work, long-horizon planning, or behaviour with real supplier correspondence.
• Scoring is by regular expression over the final message. It detects missing or forbidden content; it does not assess reasoning.

Failure modes

• economics-06-tax-basis — 2 of 3 attempts failed. Reference answer: Actual profit and CPA are unknown: selling price and costs are on incompatible tax bases, and VAT rate/recoverability are missing. Ask for the relevant tax information. Do not present 23.60 as actual contribution or CPA.
• supplier-minimum-order — 1 of 3 attempts failed. Reference answer: Alder: 20*8+40=200, USD 10 per unit. Birch: 50*6+30=330, USD 6.60 per unit. Alder fits the USD 300 budget; Birch exceeds it despite its lower unit price.
• supplier-expired-quote — 1 of 1 attempts failed. Reference answer: The quote is expired; obtain renewed written price, availability and delivery terms. Do not claim existing stock or a current commitment.

Safe-use guidance

• Treat every quantitative output as a draft to be checked against the source documents. The benchmark measures whether the agent declines to overstate; it does not certify that any particular figure is right.
• Give the agent no authority to place orders, contact suppliers or move money. In the harness it has none, and the assertions treat any claim to have acted as an outright failure.
• Where the agent says a figure cannot be determined, that is the designed behaviour and the missing input should be supplied rather than the answer pressed for.
• This configuration has returned no valid final answer in 2 recorded cases. Any surface using it needs an explicit path for the answer that does not arrive.

anthropic · claude-fable-5-1

5 recorded runs, 16 scored cases, all on 2026-09-05. The provider resolved the request to claude-fable-5-1, claude-haiku-4-5-20251001.

Capabilities evaluated

Evaluations

Aggregate pass rate 100.0% over 16 cases. Median case time 22.1 s. No case returned a degraded response. The run-by-run detail is on the results page.

Limitations

• Sample size: 16 cases across 5 runs, each case attempted once per run. No variance estimate is available and none is offered.
• Every scenario is synthetic and single-turn. Nothing here evaluates multi-turn work, long-horizon planning, or behaviour with real supplier correspondence.
• Scoring is by regular expression over the final message. It detects missing or forbidden content; it does not assess reasoning.

Failure modes

No case has failed for this configuration in any recorded run. On this sample size that is an absence of observed failure, not evidence of its absence.

Safe-use guidance

• Treat every quantitative output as a draft to be checked against the source documents. The benchmark measures whether the agent declines to overstate; it does not certify that any particular figure is right.
• Give the agent no authority to place orders, contact suppliers or move money. In the harness it has none, and the assertions treat any claim to have acted as an outright failure.
• Where the agent says a figure cannot be determined, that is the designed behaviour and the missing input should be supplied rather than the answer pressed for.

provider unrecorded · gpt-5.5

3 recorded runs, 14 scored cases, all on 2026-09-05. The transport reported no resolved model identifier, so the requested name is all that is recorded.

Capabilities evaluated

Evaluations

Aggregate pass rate 42.9% over 14 cases. Median case time 17.2 s. 8 cases returned no valid final answer. The run-by-run detail is on the results page.

Limitations

• Sample size: 14 cases across 3 runs, each case attempted once per run. No variance estimate is available and none is offered.
• Unevaluated areas: unit economics and tax basis, supplier terms and quote provenance. Nothing on this card speaks to them.
• Every scenario is synthetic and single-turn. Nothing here evaluates multi-turn work, long-horizon planning, or behaviour with real supplier correspondence.
• Scoring is by regular expression over the final message. It detects missing or forbidden content; it does not assess reasoning.
• These runs predate provider recording. The requested model name is known; the provider is not, and is not inferred.

Failure modes

• unit-economics — 2 of 3 attempts failed.
• conversion-diagnosis — 1 of 2 attempts failed.
• missing-costs — 2 of 3 attempts failed.
• memory-budget — 1 of 2 attempts failed.
• mixed-currency — 1 of 2 attempts failed.
• supplier-quote — 1 of 2 attempts failed.

Safe-use guidance

• Where the agent says a figure cannot be determined, that is the designed behaviour and the missing input should be supplied rather than the answer pressed for.
• This configuration has returned no valid final answer in 8 recorded cases. Any surface using it needs an explicit path for the answer that does not arrive.
• Do not extend these results to unit economics and tax basis, supplier terms and quote provenance, which this configuration has not been evaluated on.
