## In short

Velocity release of the self-improving Hermes Agent collapses run_agent.py from 16,083 to 3,821 lines, ships an orchestrator-driven Kanban swarm, and adds Promptware defense against Brainworm-class injections.

## What it is

Hermes Agent is Nous Research's open-source MIT-licensed agent framework that creates skills from experience, persists memory across sessions, and runs on 200+ models via OpenRouter, OpenAI, and Anthropic. v0.15.0 lands 1,302 commits, 747 merged PRs, and 1,746 changed files from 321 contributors. The release positions the project as a swarm-capable agent platform instead of a single-loop chatbot.

## How it works

The 16,083-line run_agent.py was decomposed across 14 cohesive agent/* modules, leaving a 3,821-line core. The Kanban subsystem gained orchestrator auto-decomposition, swarm topology, scheduled tasks, worktree-per-task isolation, and per-task model overrides across 104 PRs. session_search was rebuilt without an auxiliary LLM and dropped from ~90s to ~20ms. Promptware defense scans memory at load time and tags tool results with delimiters to block Brainworm-style indirect injections.

## Why it matters

Hermes is one of the most-starred agent frameworks on GitHub (171k stars) and Nous routinely rolls research into it before broader release. The velocity rewrite cuts per-conversation function calls by 47% (399k → 213k for a 31-turn chat), which lowers both latency and provider bills. Skill bundles let one slash command load whole workflows, and the Nous-approved MCP catalog gives self-hosters a vetted tool index.

## Who it's for

Self-hosters and indie agent builders running multi-platform Hermes deployments.
