The best DeepSeek Harness plugin for Agent's context insights and management.
dsh-context provides full context lifecycle management features.
- Context tab — an UI context dashboard for DeepSeek Harness’s context stats, composition, history, events, and messages.
/contextcommand — the slash command shows the context model for current context composition and recent context evolution.
To Install from any DeepSeek Harness installation:
dsh plugin --profile web add dsh-contextOr to update the dsh-context plugin:
dsh plugin --profile web update dsh-context@latestThen start the web UI with dsh web. No build step, no restart.
Open any session and click the Context / 上下文 tab:
Type /context (or pick it from the / menu) and press Enter: a centered dialog shows the provider-anchored occupancy headline, the six-category composition bar, and the last-10-turn trend chart — hover or click a bar for its full breakdown, exactly like the tab.
Turns, steps, how many injections, compactions, and prunes have happened.
A six-color stacked bar scaled against the model's full context window (the gray track is your remaining headroom): system prompt, tool schemas, your messages, injected context, assistant replies, and tool results — plus the top-5 most expensive tool schemas. When a conversation starts degrading, this is where you find out which part ate the budget.
One stacked bar per model request, finer than per-message. Toggle between Turn and Step granularity, scroll sideways through the session, hover any bar for a quick tooltip, and click to pin the full breakdown — including provider-reported actual prompt/output tokens next to the estimate. Hovering a bar also drives the Context browser beside it — the browser previews that step's assembled context in real time as you scrub across the history. ✂ marks where compaction or pruning happened — watch the bars drop:
Above: a real session that grew to ~563k tokens across 48 turns, then compaction (✂) recycled −535.5k in one step, and the conversation continued from a fresh, small window.
In Step granularity, hovering any bar shows that single step's context info instantly — its turn/step, timestamp, and estimated vs. provider-reported token counts:
Every compaction, tool-output prune, skill or plugin context injection, and model switch — each with its token delta, turn/step attribution, and timestamp. Filter by category (Inject / Compact / Prune / Switch) to see exactly when each kind of event happened and its impact — e.g. when a skill was injected, when instructions were added, or how much a compaction reclaimed:
The exact message list the model sees right now, newest first, with a per-message token cost.
Pick Live (next request) or any retained step from the picker, and browse what that request was actually assembled from:
Six collapsible category sections (system prompt, tool schemas, user messages, injected context, assistant replies, tool results) expand into one row per element — each with its token price — and every element expands again into its actual content: the full system prompt, each tool's description and JSON schema, message text, reasoning, tool-call arguments, and tool outputs.
- Linked with the history chart — hover any bar in the History card and the browser previews that step instantly; leave the chart and it returns to your own pick. Keep a category open while scrubbing to compare one category across steps.
- Honest about coverage — steps before a compaction are reconstructed from the removed-message archive, and the card says so when a step's makeup is only approximate. Elements older than the loaded chat window page older history in automatically when you expand them, and live injections (AGENTS.md, session-start context, …) are always listed — never a token sum without its items.
