Intro

Understand your agent's decisions
Replayable infrastructure for agent investigations

Trace includes
Analyst agents can inspect
Checkpoint forks
Fixture requirements
Replay diffs
Trial matrix
Ranked effects
Validity labels
Platform

Capture runs, branch hypotheses, and explain what changed

isplay turns agent execution into structured evidence: context inventory, checkpoints, fixture requirements, diffs, statistics, and ranked effects.

01

Capture

Record prompts, context, model calls, tool proposals, tool results, artifacts, and checkpoints

02

Replay

Run fixture-first replays from explicit checkpoints without repeating unsafe side effects

03

Branch Experiments

Apply typed interventions to context, prompts, model policy, or tool outputs and compare traces

04

Ranked Effects

Measure first divergence, fixture dependence, low-N risk, and comparable downstream effects

05

Validity Labels

Keep every conclusion bounded by replay evidence instead of unsupported causal claims

Let an agent wire replay into your project

npx skills add combined-ai/isplay --skill isplay-analysis

Recommended: install the skill, restart your agent app, then ask it to choose the adapter, capture a run, and analyze it.
