dsh-agent-replay

Harness ships a powerful Trajectory diagnostic view that is ideal for developers debugging event-level details. But when you need to explain what a session actually did to teammates, maintainers, or documentation readers, the raw event ledger is often too verbose and still carries system context and live state that should not leak. Agent Replay fills that communication gap.

It adds a native Replay tab right beside Conversation and Trajectory, turning messages, model replies, tool calls, commands, errors, and timings into a searchable, filterable timeline. You can scrub through events at 1×, 2×, or 4× speed, expand any entry for full detail, copy content, or load earlier history. When the story reads well, one click on Export Shareable Page produces a self-contained, dependency-free HTML file with dark-mode support that any recipient can open in a browser and interact with.

Before export, the plugin automatically drops system and context events as well as hidden assistant reasoning, and redacts macOS/Windows user paths, common GitHub, OpenAI, and Slack-style tokens, Bearer tokens, and key-value credentials. Agent Replay is not a replacement for Trajectory; it is a session-narrative tool designed for anyone who needs to tell a clear, safe story about an agent run and hand it off with confidence.
