Why it matters

This is the clearest signal yet that Hermes is modularizing aggressively. Builders need to know which commands now require plugin installs and how subagent routing changes multi-agent setups. The spend limits and usage gauges directly address real operational friction.

Hermes Agent v0.23.0: The Hearth Release

Official release of Hermes Agent v0.23.0. Full Desktop workspace now runs in any browser tab (including phone). One gateway owns every conversation across CLI, TUI, Desktop, bots, and cron.

Plugin catalog grew from ~600 to 1,050+. ~1,950 PRs from 666 contributors.

Hermes Skill Lock + Pre-LLM Blocking Hooks (v0.22.6/7 window)

HermesWatcher highlighted key changes from the Nov 1–3 merge window (rolled into v0.22.6/7): Skill Lock lets you lock individual skills from Desktop or CLI so Hermes cannot rewrite them via skill_manage, write_file, patch, or terminal. Plugins and shell hooks can now block a request before it ever reaches the model (no tokens spent). Approval prompts surface hidden Unicode/control characters. `/model reset` restores default model without losing conversation. Cron jobs receive actual run time + timezone.

Hermes Agent v0.22.5 Patch + Pluggable Delegation

v0.22.5 (stable ~Oct 22–23) rolled up ~81 PRs / 231 commits. Notable: pluggable delegation backends (route subagents by model or profile), simplified Nous device sign-in, usage-window plan support, Windows update recovery, and moving certain features (mcp serve, Singularity) out of core into plugins. Full curated notes deferred to v0.23.0.
