OpenClaw Output Metrics Footer

Use this skill when an OpenClaw workspace should show compact runtime metrics under text channel outputs.

Default footer:

_🟢 ↑54k ↓157 · 21%ctx · 5h 89% · kimi-k2.6:cloud_

With subagent aggregate:

_🟢 ↑54k ↓157 · 21%ctx · 5h 89% · openai-codex/gpt-5.5 · sub ↑31k ↓4k_

What it does

• Adds a provider-agnostic channel delivery-time footer using OpenClaw plugin hooks.
• Uses llm_output for actual model/token metrics.
• Uses message_sending to append the footer without adding prompt tokens.
• Uses live/cached OpenAI Codex OAuth usage for 5h 89% when available.
• Uses color status from context usage and quota remaining.
• Optionally aggregates nearby subagent LLM usage.

Install into an OpenClaw workspace

Copy the bundled extension template:

mkdir -p ~/.openclaw/extensions/openclaw-output-metrics-footer
cp -R assets/extension-template/* ~/.openclaw/extensions/openclaw-output-metrics-footer/

Add this plugin config to ~/.openclaw/openclaw.json:

{
  "plugins": {
    "allow": ["openclaw-output-metrics-footer"],
    "load": {
      "paths": ["~/.openclaw/extensions/openclaw-output-metrics-footer"]
    },
    "entries": {
      "openclaw-output-metrics-footer": {
        "enabled": true,
        "hooks": {
          "allowConversationAccess": true
        },
        "config": {
          "enabledChannels": [],
          "cacheMs": 120000,
          "quotaCacheMs": 60000,
          "contextReserveTokens": 40000,
          "appendSubagents": true,
          "disabledChannels": [],
          "disabledConversations": []
        }
      }
    }
  }
}

Then validate and restart:

openclaw config validate
openclaw gateway restart

Channel deployment

The plugin can run for any OpenClaw text channel that emits message_sending.

Use enabledChannels to restrict to specific providers, such as ['discord', 'telegram']. Leave it empty to enable all text providers.

Use disabledChannels to disable whole providers.

Use disabledConversations to disable specific channel/chat/conversation IDs.

Recommended defaults:

• Enable in active work channels like #general, #coding, #reasoning, Telegram work chats, and audit channels.
• Disable in status-only channels like #feed and incident channels like #system if noise matters.

Configuration

Fields:

• enabledChannels: optional provider allowlist. Empty means all supported text channels.
• cacheMs: window for matching recent LLM output and subagent output.
• quotaCacheMs: minimum interval between Codex quota refreshes.
• contextReserveTokens: safety reserve included in context percentage calculations.
• appendSubagents: append sub ↑x ↓y when nearby subagent usage is detected.
• disabledChannels: provider IDs where no footer should be appended.
• disabledConversations: channel/chat/conversation IDs where no footer should be appended.

Color status

• 🟢: context under 50% and quota over 50%.
• 🟡: context 50-80% or quota 20-50%.
• 🔴: context over 80% or quota under 20%.

If context and quota disagree, show the worse status.

Guardrails

• Do not put footer instructions in agent prompts.
• Do not call an LLM to calculate footer metrics.
• Do not fetch Codex quota on every message; use cache.
• Do not show emails, OAuth profile names, token values, API key prefixes, or auth file paths.
• Do not add the footer when it would exceed the channel message limit.
