Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

bluebubbles-hardened scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

94% identical to bluebubbles — 13 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

BlueBubbles plugin

Use this skill when working on the BlueBubbles channel plugin.

Layout

  • Extension package: extensions/bluebubbles/ (entry: index.ts).
  • Channel implementation: extensions/bluebubbles/src/channel.ts.
  • Webhook handling: extensions/bluebubbles/src/monitor.ts (register via api.registerHttpHandler).
  • REST helpers: extensions/bluebubbles/src/send.ts + extensions/bluebubbles/src/probe.ts.
  • Runtime bridge: extensions/bluebubbles/src/runtime.ts (set via api.runtime).
  • Catalog entry for onboarding: src/channels/plugins/catalog.ts.

Internal helpers (use these, not raw API calls)

  • probeBlueBubbles in extensions/bluebubbles/src/probe.ts for health checks.
  • sendMessageBlueBubbles in extensions/bluebubbles/src/send.ts for text delivery.
  • resolveChatGuidForTarget in extensions/bluebubbles/src/send.ts for chat lookup.
  • sendBlueBubblesReaction in extensions/bluebubbles/src/reactions.ts for tapbacks.
  • sendBlueBubblesTyping + markBlueBubblesChatRead in extensions/bluebubbles/src/chat.ts.
  • downloadBlueBubblesAttachment in extensions/bluebubbles/src/attachments.ts for inbound media.
  • buildBlueBubblesApiUrl + blueBubblesFetchWithTimeout in extensions/bluebubbles/src/types.ts for shared REST plumbing.

Webhooks

  • BlueBubbles posts JSON to the gateway HTTP server.
  • Normalize sender/chat IDs defensively (payloads vary by version).
  • Skip messages marked as from self.
  • Route into core reply pipeline via the plugin runtime (api.runtime) and openclaw/plugin-sdk helpers.
  • For attachments/stickers, use <media:...> placeholders when text is empty and attach media paths via MediaUrl(s) in the inbound context.

Config (core)

  • channels.bluebubbles.serverUrl (base URL), channels.bluebubbles.password, channels.bluebubbles.webhookPath.
  • Action gating: channels.bluebubbles.actions.reactions (default true).

Message tool notes

  • Reactions: The react action requires a target (phone number or chat identifier) in addition to messageId. Example: action=react target=+15551234567 messageId=ABC123 emoji=❤️

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
