Session replay. Compare recorded skilled and baseline trajectories side by side.
Open session replayThese filters apply to catalogue, quality, efficiency and model comparison.
Usage order
Product preflight, then engineering
Optional standalone product workflows precede the single engineering entrypoint. Brownfield and other roots stay independent.
Source-derived catalogue
Agents, workers, lenses and skills
Controlled comparison
Quality and activation
How to read quality
Each model is compared with and without the skill. Models appear together only when the same judge scored them; “highest score” applies to this skill and judge, not to every task.
- Baseline
- Score without the skill.
- Skilled
- Score from the same model with the skill available.
- Lift
- Skilled minus baseline. Positive means the skill helped on this run set.
- Activation rate
- How often the skill loaded when expected.
- Unexpected
- Loads on prompts where the skill should have stayed inactive. Zero is the target.
- Verdict
- Statistical conclusion across paired trials, not a single success or failure.
Runtime profile
Efficiency
How to read efficiency
Compare each model with its own baseline. Lower resource use is useful only when quality remains acceptable; efficiency alone does not identify the best model.
- Duration
- Median elapsed time per trial.
- Tokens
- Median model input and output volume per trial.
- Turns
- Median number of agent reasoning cycles.
- Tool calls
- Median number of external actions taken by the agent.
- Delta
- Change from baseline. A negative percentage means the skilled run used less.
One arm per agent model
Model comparison
How to compare models
One row is one agent model. Compare rows only inside the same table: they used the same skill and were scored by the same judge. “Highest score” is local evidence, never a universal model ranking.
- Agent model
- Model that performed the task.
- Judge
- Model that scored the outputs against the rubric.
- Highest score
- Largest skilled score in this table; inspect lift and efficiency before deciding.
