Hermes Agent v0.19.0: ~80% faster first token, smart approvals on by default, password-manager secrets

Large Hermes release cutting cold-start time to first token from ~4.3s to ~0.9s across CLI, gateway, TUI, desktop and cron, with reasoning now streamed live by default. It also flips flagged-command approvals to LLM-reviewed by default, adds Bitwarden/1Password as secret sources, live subagent transcripts, and a durable ledger so a finished response survives a gateway crash. Anyone running Hermes unattended or with approval gates should read the approval-behaviour change before upgrading.

  • Cold-start agent init ~4.3s → ~0.9s (~80% cut) on CLI, gateway, TUI, desktop, cron
  • Reasoning models stream thinking live by default; response box paints per token instead of per line
  • Desktop: 20+ perf PRs — 14× cheaper markdown splitting on long replies, virtualized diff pane, no sidebar/tool-row re-render per token, backend pre-warm on hover, idle-mount for hidden panes
  • TUI renders markdown incrementally
  • /subscription and /topup manage the Nous plan from TUI or classic CLI: plan + remaining allowance, upgrade cost preview, downgrade timing, scheduled-change banners, undo; matching desktop billing settings tab
  • Smart approvals now default: an LLM reviewer assesses each flagged command, verdicts scoped to that exact command (no pattern-wide blanket approval)
  • User-defined deny rules block commands even under yolo mode; /deny <reason> passes the refusal reason back to the agent
  • New pluggable SecretSource interface: Bitwarden and 1Password (op:// refs) at load time, multiple vaults at once, deterministic precedence, conflict warnings, per-variable provenance
  • delegate_task writes one live human-readable transcript file per subagent (tail-able during the run)
  • Background delegation completions are durable — results restored and delivered through an ownership-checked ledger after a restart
  • Final responses recorded in a delivery-obligation ledger in state.db so a gateway crash between generation and platform delivery no longer loses a paid turn
  • Rolls up the v0.18.1 and v0.18.2 infrastructure patch tags
  • Window totals: ~2,245 commits, ~1,065 merged PRs, ~3,300 issues closed, 450+ contributors
