anti-hallucination-gates

Use before claiming done/fixed/passing — or before asserting something is absent: not installed, not available, no such function, couldn't find it. Default-FAIL runs both ways — every claim needs an evidence path. A negative claim must carry its search scope and observation date; state calibrated uncertainty when evidence is missing.

# Anti-Hallucination Gates

The most common agent failure is **declaring victory too early**. This skill is the gate between "I think it works" and "evidence proves it works".

## The Iron Rule

> No claim of "done" / "fixed" / "passing" without a concrete artifact path proving it.

A claim like *"I fixed the bug"* is incomplete. The proper form:

> "Fixed by commit `abc123`. Test `tests/foo.test.ts::handles-edge-case` now passes (output captured in `.harness-anchor/test-2026-05-28.log`). Build still passes (`.build/last-build.log` exit 0)."

## The Iron Rule runs both ways
