dsh-context

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, trend, events, and messages.
• /context command — the slash command shows the context model for current context composition and recent context evolution.

Install / Update

To Install from any DeepSeek Harness installation:

dsh plugin --profile web add dsh-context

Or to update the dsh-context plugin:

dsh plugin --profile web update dsh-context@latest

Then start the web UI with dsh web. No build step, no restart.

Use it

Three surfaces, one story — what your agent is carrying, how it got there, and what it did with it:

Where	What you get
Context tab	The full dashboard: stats, composition, per-request trend, events, file activity, and the agent network — in every session.
/context command	A centered modal with the same composition and context browser, without leaving the chat.
Settings → Plugin configuration	Per-user defaults: trend granularity & mode, File Activity sort.

📊 The Context tab

Open any session and click the Context / 上下文 tab:

Card	The question it answers
Context Stats	Turns, steps, live tool calls & images, context-event tallies — plus a list-price cost estimate (hover the ? for per-1M rates).
Token Stats	Where the billed tokens went: cache read/write, uncached input, output — around the cache-hit ring.
Timing Stats	How active time split across model calls, tool runs, and overhead.
Current Context	What's in the window right now.
Context Trend	Every request's size — and its story.
Context Browser	What any request was actually assembled from.
Context Events	When and why the window changed.
File Activity	What the agent did to your files.
Agent Network	The whole agent family, live.

The headline occupancy and composition read the same official token-meter projections as the chat composer's context ring (contextPressure / contextBreakdown), so the figures always match what the ring tells you.

🧱 Current Context — who ate the budget

A six-color stacked bar against the model's full window (hatching = free headroom): system prompt, tool schemas, user messages, injected context, assistant replies, tool results — each with its ≈token figure and share. When a conversation starts degrading, this is where you see which part is responsible.

📈 Context Trend — every request, sized and explained

One stacked bar per model request — finer than per-message — so you watch the window grow turn by turn:

• ✨ Step brief — three plain-language rows under the chart: User recalls the message that opened the turn, In lists what newly entered (usually the previous tool results), Response shows the reply and/or tools called. Click a row to open that exact message in the Context browser.
• ✂ marks the events — compactions and prunes are pinned to the bar where they happened, so the drops explain themselves.
• Read it your way — Step / Turn granularity, Total (cumulative makeup) or Delta (each request's signed change), and sideways scrolling through the whole session. In Delta mode, growth piles up above the baseline and a compaction dives below it:

• Hover & pin — scrub for an instant tooltip; click to pin the full breakdown, with provider-reported Actual Prompt / Output / Cache next to the estimates.
• Live linkage — hovering a bar previews that step's assembled context in the Context browser beside the chart; leaving the chart returns to your own pick.

🧭 Context Browser — open the box of any request

Pick Live (next request) or any retained step, and browse what that request was assembled from: six collapsible categories expand into one row per element with its token price, and every element expands again into its actual content — the system prompt, each tool's JSON schema, message text, reasoning, tool arguments, and tool outputs.

• Who provides each tool — every tool-schema row carries a best-effort source chip: tool-* first-party packages, dsh-* capability packages, mcp:<server> proxies, or the exact plugin watched live from tools.register(). Sort by size / name, and filter every category by its own searchable fields:

• Tool results open into the full call — the tool name and arguments with its OK/error status, the result body with line count and a Raw / Markdown toggle:

• Image payloads render as cards — thumbnails with name, dimensions, stored size, and the official DeepSeek image-token estimate (the dsh multimodal pipeline, e.g. read_image results and image attachments):

• Diff against the previous turn — signed delta badges per category (+N items, ±Nk tokens) tell you what a turn added or reclaimed at one glance. Steps older than a compaction are reconstructed from the removed-message archive — and the card says so when a step's makeup is only approximate.

⚡ Context Events — when and why the window changed

Every injection, compaction, prune, model switch, and plan-mode toggle — labeled with its producer (instruction file, plugin id, skill name), its net token delta (compactions show what they reclaimed), turn/step, and time. The Inject / Compact / Prune / Switch / Mode chips filter the log by kind.

📁 File Activity — what the agent did to your files

One row per touched file — read, written, or searched — aggregated up to whichever step you pick on the trend chart:

• Per-purpose counts with header chips doubling as filters (Read / Written / Searched / Images) and a path search box.
• Line deltas — every edit/write contributes its estimated +added / −removed footprint, per file and summed.
• Every mode counts — native tools, the Minimal preset's str_replace_editor, and the nested calls inside PTC run_code programs are all folded into per-tool rows.
• Searches land on real files — matched files get their own ops rows with hit counts.
• Click a row to expand its full operation log — every op jumps straight to the exact tool result in the Context browser.

🕸 Agent Network — the family portrait

The current agent, its parents, and every subagent — one node per agent, colored edges for the lineage, multi-level delegation on one map. Each ring is that session's composition scaled to its window occupancy; hover for tokens, requests, billing, and active time; click to jump into that session's own Context tab. Running agents breathe with a green pulse.

⌨️ /context command

Type /context (or pick it from the / menu) and press Enter:

A centered dialog opens with the Current Composition card and the Context browser — the same composition bar, per-step picker, and vs previous turn diff badges as the tab:

⚙️ Settings

In Settings → Plugins → Plugin configuration, the Context card holds this plugin's per-user preferences — default trend granularity (Step/Turn), default trend mode (Total/Delta), and the File Activity default sort. In-chart and in-card toggles stay per-view and never overwrite the stored preference.

Good to know

• Estimates vs actuals — category figures use dsh's own fixed-density heuristic (the same one as its built-in token meter); the pinned trend details and Token/Timing rings show provider-reported actuals next to them.
• Compatibility — works on @deepseek-ai/dsh 0.1.2-rc1+. The per-release matrix and how it is verified: docs/compatibility.md.
• I18n — UI in English and 简体中文.
