dsh-green-meter

Energy & carbon metering for DeepSeek Harness — see what your agentic sessions cost.

A dsh-plugin that turns every model call into energy (J/kWh), carbon footprint (g CO2e) and electricity cost (CNY) — estimated from token accounting, so it works with any API-backed provider (DeepSeek API, OpenAI-compatible endpoints, local vLLM) without touching hardware.

Install it, chat as usual, and watch your session's energy bill in real time.

✨ Features

Surface	What you see
Composer dock (always visible under the input box)	live 能耗 1.5 kJ · 碳 0.2 g readout + per-turn energy sparkline
Detail panel (click the readout)	floating draggable drawer with per-turn energy chart, per-request energy list, session totals (tokens / energy / carbon / electricity cost), carbon saved by caching ≈ N trees per year
/green	one-command session energy report
green_meter tool	the agent can query its own energy, carbon, cost and budget at any time
Energy budget	optional per-session budget — over-budget steps are rejected with a warning
JSONL ledger	every model call recorded, ready for your own analysis

🚀 Quick start

# 1. Install into your dsh profile
cd ~/.dsh/profiles/web          # (Windows: %USERPROFILE%\.dsh\profiles\web)
pnpm add dsh-green-meter dsh-client-ui-green-meter

# 2. Mount the plugins in your profile's cordis.patch.yml (see examples/)

- insert:
    - id: green-meter
      name: 'dsh-green-meter'

    - id: ui-green-meter
      name: 'dsh-client-ui-green-meter'
      config:
        panelPlacement: overlay   # overlay (default) = floating draggable drawer, zero-config

Restart dsh web, refresh, and the readout appears under the composer. Type /green anytime.

The detail panel opens as a floating drawer you can drag anywhere — no changes to the DeepSeek Harness repo are needed. panelPlacement can be omitted (overlay is the default); popover is another patch-free option.

Sidebar panel (optional, needs a one-time DSH edit)

panelPlacement: sidebar renders the detail panel inside the sidebar's blank space. Skip this section if the drawer above is enough — it is the recommended setup. The seat needs one small addition to packages/client/ui-sidebar (everything else stays untouched). Two ways, pick one:

A. Patch (fresh checkout of deepseek-harness)

cd /path/to/deepseek-harness
git apply /path/to/dsh-green-meter/patches/ui-sidebar-sidebar-energy.patch
pnpm --filter @deepseek-ai/dsh-client-ui-sidebar bundle

B. Anchor-based installer (any version; use this when git apply fails)

cd /path/to/deepseek-harness
powershell -ExecutionPolicy Bypass -File /path/to/dsh-green-meter/patches/apply-sidebar-energy.ps1
pnpm --filter @deepseek-ai/dsh-client-ui-sidebar bundle

The installer edits by unique code anchors (no line numbers), so it works even when the patch's context no longer matches your checkout, and it is idempotent — running it twice is safe.

⚙️ Configuration

Key	Default	Meaning
profile	proxy	calibration profile (proxy, qwen-h20-*, gemma-h20-*, qwen3-4b-*)
carbonFactorKgPerKwh	0.5777	grid carbon intensity
electricityPriceCnyPerKwh	0.56	electricity price (CNY/kWh)
dir	<DSH_HOME>/green-meter	ledger directory
budgetJ	0 (off)	session energy budget in joules

Environment fallbacks: DSH_GREEN_PROFILE, DSH_GREEN_CARBON_FACTOR, DSH_GREEN_PRICE_CNY, DSH_GREEN_DIR, DSH_GREEN_BUDGET_J.

📌 Method notes

• Estimate, not measurement — energy is modeled from token accounting with calibrated per-model profiles; carbon and cost are energy × configurable factors.
• GPU operational energy only — CPU, memory, cooling and embodied carbon are out of scope.
• Cache savings are counterfactual — cached tokens that would otherwise be recomputed.
