Trinity v0.8.5 — async orchestration, skill packages, shared rooms

[vybe]

Trinity v0.8.5 is out: 773 commits, 619 files changed, ~95 issues closed. The theme of this release is coordination — agents that work with each other, and with time, instead of being polled.

Async orchestration

• Task-completion events (feat: system-emitted agent.task.completed/failed events at execution terminal (async caller report-back) #1578) — the platform emits agent.task.completed/failed at every execution terminal; subscribed agents are woken with the outcome, duration, and cost. Orchestrators no longer poll for results.
• Agent self-reminders (feat: agent self-reminders — agent-callable one-shot deferred self-trigger ("remind me to do X later") #1296) — an agent schedules a future re-invocation of itself with a message it picks. Durable, bounded, survives restarts.
• Shared rooms (enterprise) — multi-agent sessions with a mention-wake turn engine, budgets, and a dashboard Sessions view.

Platform

• Skills as full packages — a skill is now a directory (SKILL.md + scripts/templates/resources) with versioning and safe manifest-based sync; a stateless skill-runner executes library skills over MCP (enterprise). Backward-compatible — existing agents self-heal to the new format on next sync.
• Agent display names — an editable human-facing label on an immutable slug, rendered across the UI, pickers, search, and operator surfaces.
• Ghost agents (enterprise) — disposable budgeted agents that hard-discard at their execution/TTL budget.
• Per-user GitHub credentials — each user brings their own PAT (wired into git and the gh CLI); public github: templates clone with no token at all.
• Voice replies v2 — voice is a per-message agent capability with agent-level settings and a platform ElevenLabs key.
• Two-tier telemetry — Tier-1 local product events (default-on, never leave the box); Tier-2 fleet sharing is opt-in and default-off.

Fleet hygiene

Git bloat inside agent containers root-caused and bounded, Docker volume lifecycle + orphan reclaim, and a blast-radius guard on retention prunes with an in-product approval path.

⚠️ Upgrading in place

Rebuild platform images (docker compose build) and the agent base image (./scripts/deploy/build-base-image.sh) — several features (tokenless clone, git maintenance, gh CLI) live in the new base image. Details in the notes.
