octet 0.6.0

Released 2026-08-23.

Highlights#

Subagent overhaul — extension-routed child sessions with raised limits (eight concurrent workers), opt-in edit/write/bash mutation grants, continue/resume across sessions, live worker telemetry while root tools run, a native /subagents browser, and styled subagent transcripts in the TUI.
First-party extension bundles ship for the first time — checksum-verified, atomically installed, inert until enabled and trusted: ygg-browse, ygg-web-search, ygg-mcp, ygg-subagents, plus the version-matched loopback-only ygg-serve.
Deferred tool-schema loading ported from Pi's deferred-tools design: tools registered mid-session are announced on the tool result and excluded from static request schemas by deferred-capable providers.
Tool wall-time telemetry, bash-only duration rendering, and speculative recon execution.
Responses WebSocket preferred where available; improved provider failure diagnostics.
ygg-web-search: web_open renamed to web_fetch (extension v0.3.0).
The ygg-ssh portal extension was removed from the catalog.

Extension bundles require executable-extension API 0.2 and Ygg = 0.6.0 for the version-matched Serve package.
Prompt templates remain Pi-compatible; skills follow the Agent Skills spec.
