Using Axe
Evidence and sources
How Axe ties claims to their sources, separates facts from calculations and assumptions, and says plainly when evidence is missing.
Research is only useful if it can be checked. Axe keeps the evidence for its work next to the work itself.
Every claim keeps its source
When a result states something it found, it records where: the document or page, the location within it, and the excerpt or value it relied on. Select a claim's numbered marker to see its source, and the sources list under the answer shows them all, so a reviewer can confirm a figure in one step.
Facts, calculations and assumptions
Results from an Agent go one step further and label each output by the kind of support behind it:
- Fact: taken directly from a source.
- Calculation: derived from other outputs. The result shows the formula and which inputs it used.
- Assumption: a judgement the method calls for, stated as one.
When evidence is missing
Axe does not fill gaps. When a value cannot be established, the result says so and gives the reason: not found, not applicable, access blocked, or unclear. The rest of the result still arrives, with the gap marked where the value would be.
Checks in a workflow
An Agent's workflow can include checks, steps that test the work against a rule in your method before it continues. Axe evaluates the rule in code against the values the run recorded, rather than asking the AI whether its own work is right. A run shows whether each check passed or failed, and which way the workflow went as a result. See Running an Agent.
