Trajectories

Agent trajectory evaluation with reviewable evidence

The final answer is not enough. AgentClash evaluates the trajectory — tool choices, observations, retries, artifacts, and stop conditions — then preserves replay evidence for auditors and release owners.

Why trajectories matter

Built for reviewable agent decisions

Two agents can return the same answer while taking wildly different paths. Trajectory evaluation catches unsafe shortcuts, runaway loops, and brittle tool strategies.

OpenTelemetry-compatible trace import

Pinned datasets and golden test cases

Baseline versus candidate regression checks

Replay trails for tool calls, outputs, and artifacts

Scorecards for correctness, cost, latency, and evidence

CI gates for prompt, model, RAG, and tool changes

Workflow

Trajectory eval workflow

Import the evidence

Start from OpenTelemetry traces, curated datasets, support transcripts, or a real failure your team already saw.

Pin the baseline

Record the current accepted behavior so every prompt, model, RAG, or tool change has a fair comparison point.

Replay the evidence

Inspect tool calls, outputs, artifacts, latency, cost, and judge evidence when a candidate gets worse.

Gate the release

Compare candidate and baseline runs, then fail CI before a regression reaches users.

FAQ

Trajectory evaluation FAQ

What is agent trajectory evaluation?

Trajectory evaluation scores the sequence of actions and observations an agent took to complete a task, not just the final output string.

How does AgentClash store trajectory evidence?

Each run keeps replay events, tool calls, logs, artifacts, and scorecards so reviewers can reconstruct the path that produced the result.

Can trajectory evals gate releases?

Yes. Compare candidate and baseline trajectories via scorecards, then fail CI when correctness, cost, latency, or evidence quality regresses.
