Your agent has a policy. We find the failure path.

Connect or simulate your AI agent. EvalDuel attacks it through RAG poisoning, tool misuse, trust impersonation, and file-read attack scenarios—then turns the break into a replayable report.

01 / ATTACK LAB

Paste the policy. Watch the assumption break.

This is a real evaluation request, not a decorative score generator. The result comes from EvalDuel's live analysis endpoint.

policy.txt

The attack engine will probe authority, retrieval trust, tool boundaries, and file access.

attack-report.jsonLIVE ENDPOINT
StatusReady for EvalDuel attack

Submit the policy to generate a live attack report.

Attacked bytrust impersonation

A fake teammate claims authority using a real internal project name.

Failure modeUnsafe Trust Transfer

The policy treats memory-shaped knowledge as permission.

Score62 / 100

Attack succeeded, but the agent preserved some normal behavior.

Fix suggestionVerify authority, not familiarity.

Share card: Knowing a secret-shaped fact is not the same thing as being authorized.

02 / FAILURE LIBRARY

The replay is the product proof.

Each case preserves the attack, the behavior that failed, and the smallest policy change that prevents a repeat.

01Unsafe Trust Transfer

The attacker knew a real project name. The agent mistook context for authority.

Fix / Require authority verification, not memory matching. 02Over-blocking

The defense stopped a protected read by breaking normal public routes too.

Fix / Preserve benign routes while blocking protected reads. 03Poisoned Retrieval Acceptance

A retrieved document injected a rule and the agent promoted it into policy.

Fix / Separate retrieval usefulness from source authority.

04 / TRUST MODEL

The agent can submit actions. It cannot grade itself.

Powered by the Wild Arena engine. EvalDuel keeps validation and scoring server-side, exposes public rationale instead of private chain-of-thought, and turns every failure into a regression artifact.

01
Hidden validators

Prevent memorizing the test or optimizing for visible strings.

02
External scoring

The arena—not the agent—writes scores, ratings, and match history.

03
Replayable evidence

Failures remain inspectable, comparable, and reusable after the match ends.

05 / LIVE ARENA
