dsh-timeline

DeepSeek Harness session history is often a long stream of messages and tool calls. Grasping how the AI actually broke down a problem means scrolling through everything twice. dsh-timeline reshapes that raw trace into an S-shaped energy timeline: turn cards are laid out in a boustrophedon pattern, a blue-to-purple-to-pink gradient Bezier curve threads through the centre of every card, and a glow layer with pulsing light particles turns a dry event list into a rhythmic visual narrative.

The real differentiator is the process-insight layer. Each turn's tool calls are distilled into readable conclusions: multiple greps become "three searches to locate key code", read/write operations are graded by frequency, bash executions are counted, and errors are tagged with a first-failure and fix marker. A causal logic chain (search, read, modify, verify) strings each step into a readable intention. The timeline header aggregates full-trace stats: turn count, total tool calls, top-3 hottest files with heat bars, and a tool-type distribution, all on one screen.

Who is it for? DSH users who need to quickly review a complex session, walk a colleague through the AI problem-solving path, or extract structured insights from a wall of tool calls. Switch to the Timeline view and the timeline opens automatically; click any card header for a detail popover; zoom with Ctrl/Cmd plus scroll; close layers one by one with ESC. Zero configuration, ready to use.
