Contains Valid Link
Evaluates whether output text contains at least one valid hyperlink formatted to standard URL conventions.
Contains Valid Link checks whether a response includes at least one properly formatted URL. Run it wherever a response is expected to point users to a link.
What it does
Contains Valid Link is a deterministic, rule-based eval. It scans the provided text and checks whether it contains at least one valid hyperlink.
Input
| Required Input | Type | Description |
|---|---|---|
text | string | The content to be assessed for valid hyperlinks |
Output
| Field | Type | Description |
|---|---|---|
| Result | Pass / Fail | Pass means the text contains at least one valid hyperlink; Fail means it doesn’t |
| Reason | string | A plain-language explanation of the link validation assessment |
Run it from code
Call evaluate() with the template name and the eval’s required inputs. It returns the score and the reason.
Note
Before running: install the SDK and set FI_API_KEY / FI_SECRET_KEY. The model argument in the snippets is the evaluator model Future AGI uses to run the eval; turing_flash is a fast default.
from fi.evals import evaluate
result = evaluate(
"contains_valid_link",
text="Check out our documentation at https://www.example.com",
model="turing_flash",
)
print(result.score)
print(result.reason)import { evaluate } from "@future-agi/ai-evaluation";
const result = await evaluate(
"contains_valid_link",
{
text: "Check out our documentation at https://www.example.com"
},
{ modelName: "turing_flash" }
);
console.log(result);When to use
Run Contains Valid Link wherever a response is supposed to direct the user to a resource.
- Text outputs like support replies or help-center answers that should reference a documentation link
- Content generation tasks where a citation or source link is a required element
- Regression checks after a prompt change, to confirm the model still includes expected links
What to do when Contains Valid Link fails
If the evaluation fails, review the output text to identify the absence of valid links. Consider revising the content to include appropriate hyperlinks that meet the required standards. Providing clearer instructions or constraints in the input can help prevent this issue in future evaluations.
