operating-live-sinks

operating-live-sinks is a skill for Claude Code from Extelligence-ai/bagel. It costs 45 tokens per session (227 once invoked), scanned A, original, Apache-2.0.

A setup for recording live robot data from sources such as MQTT and rosbridge into rolling, per-topic files on a bagel server.

In plain words
What is it for?
Use it to discover available robot data, start live recording, run queries or pipelines on the recorded files, and preserve startup pipelines and exported artifacts.
Why use it?
It keeps ongoing data recordings and processing pipelines running across restarts while limiting each topic's disk buffer size.

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

operating-live-sinks 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.

What it actually says

Operating live sinks

Live data flows into per-topic rolling disk buffers on the bagel server; standing pipelines run against them.

  • Discover what a live source publishes with list_live_topics, then subscribe_live_topics to start recording; each topic gets a rolling buffer (JSONL_BUFFER_SIZE_PER_TOPIC_BYTES, default 1 GB per topic).
  • The subscription's directory path is returned; pass it as the path for queries and pipelines over the live data.
  • Standing pipelines that must survive container restarts belong in the STARTUP_PIPELINES_FILE manifest: they are re-established on boot.
  • Artifacts (snippets, exports) land under the artifacts directory and are never cleaned up automatically: they are the user's deliverables. See references/settings-knobs.md for every knob and its default.

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.
