Pi · operational visibility

One place to see what my agents are doing.

I wanted a simple view of the agents Herdr is managing. Black Signal Cockpit keeps the roster visible and adds richer diagnostics when a harness publishes them.

Representative Black Signal Cockpit terminal panel showing session, model and context, tools, version control, and worker telemetry for one selected Pi agent. — The selected-agent view mirrors Pi’s /cockpit layout. This screenshot uses representative data rendered by the plugin’s production code; it is not a live session capture.

The join is the product.

Herdr inventorySupplies the live roster, pane identity, workspace, focus, and basic process status.

Versioned snapshotsAdapters publish bounded telemetry keyed to the same Herdr pane and workspace.

Unified diagnosticThe selected agent is projected into the familiar session, model, trace, tools, VCS, and workers view.

Useful detail without invented certainty.

Harnesses: Agent kinds are arbitrary strings; there is no Pi/Codex allowlist.
Missing data: Unavailable capabilities stay unavailable instead of being inferred.
Freshness: Published records expire after five minutes and are pruned during reads.
Controls: Tab switches agents; j/k scrolls; r refreshes.

The telemetry boundary is explicit. Publishers should not emit prompts, responses, tool arguments or results, environment values, or credentials.

Evidence boundary: architecture and controls reflect the README and renderer at commit 969171167147528ea1d382e4fc2d3aaab6a11895. The screenshot’s values are illustrative, while its structure and styling are produced by the real panel renderer.
