Hermes Agent v0.21.0
Hermes Agent v0.21.0 is out. Your agents get names, faces, and group chats. Scheduled jobs remember what they did yesterday. And you can reach into a running subagent and change its course.
01 Your agents, as a team
Your agents, as a team.
Every agent gets a name and a face
- Bot Mode is bundled and on by default
- Group chats hold several bots and you
- @-mention any bot from the composer
Bot Mode is bundled into the desktop app and on by default. Every agent profile gets a name and a generated avatar face. Put several bots and yourself in one room, and at-mention any of them straight from the composer.
Bots message each other by handle
hermes peerreaches across profiles and gateways- Send from the command line or inside a conversation
- Replies land in each bot's own chat, so the exchange stays inspectable
The hermes peer command lets any agent message any other by handle, across profiles and gateways. Send it from the command line or from inside a conversation. Ask your research bot to hand findings to your coding bot, and the reply comes back to you.
Scheduled jobs remember the last run
- Cron agents load and update persistent memory
continuity=truecarries each run's output into the next- Monitor jobs skip the model entirely when nothing changed
Cron agents now load and update persistent memory like every other agent. Turn on continuity and each run's output carries into the next, so a monitor can dedupe against what it already reported. Monitor jobs skip the model when nothing changed.
02 Hands on the wheel
Hands on the wheel.
Steer a subagent while it runs
- List the children that are running right now
- Send one a course correction mid-flight
- Stop one early and keep the partial result
- New defaults: 250 iterations, 10 concurrent children
Delegation gained live orchestration. List the children that are running, send one a course correction mid-flight, or stop it early and keep the partial result. The defaults rose to 250 iterations and 10 concurrent children.
Every MCP server on one page
- Servers and catalog merged, drag anything in to import it
- Health checks nudge you to sign in again before a call fails
- Schema token estimates and 30 days of usage, per server
hermes://links install a server after you confirm
MCP servers and the catalog merged into one desktop page, and you can drag anything in to import it. Health checks nudge you to sign in again before a tool call fails, and an overlay shows schema token estimates and thirty days of usage per server.
The terminal picked up a command palette
Ctrl+Popens fuzzy search over every command/statusshows reasoning mode, pending approvals, context used- Status bar carries cache hit rate, latency, tokens per second
- A global emergency stop, and terminal pets
Control P opens a fuzzy command palette. Status shows your reasoning mode, pending approvals, and context usage. The status bar can carry cache hit rate, latency and tokens per second. There is also a global emergency stop, and terminal pets.
03 New ground
New ground.
The agent drives the in-app browser
- Hermes navigates, clicks, and reads the page directly
- Walk a docs site or debug a web app inside your own app
- Pop any page out to your system browser
The desktop browser used to be a window the agent could only look at. Now Hermes navigates it, clicks in it, and reads the page directly. Ask it to debug a web app and watch it happen inside your own app.
Six providers arrive built in
model_overrides patches any model
Six providers ship built in: Meta's Model API, CommandCode, Tencent TokenPlan, Nebius Token Factory, Ramp Router, and Actual Computer. The catalogs picked up GLM-5.3-Flash, qwen3.8 max and flash, and Gemini 3.7 Flash. Model overrides let you patch any model's context window or pricing yourself.
New skills you can call today

publish-siteships versioned sites to GitHub, Cloudflare or Netlify Pagesmerge-reconcilersettles conflicts between agents- Inbox triage, meeting action items, issue to pull request
A new skill watches a website once, then calls its hidden API directly, with no browser in the loop. Publish site does versioned publishing to GitHub, Cloudflare or Netlify Pages. A productivity wave covers inbox triage, meeting action items, and issue to pull request.
An injected agent cannot rewrite its own orders
- Writes to
AGENTS.md, skills and memory always need approval - Redaction closed leaks in terminal errors,
.envreads, checkpoints - Destructive Windows commands trip the approval system
- macOS permission grants survive every update
Writes to agents markdown, skills, and memory stores now always require approval, so a prompt-injected agent cannot quietly rewrite its own standing orders. A redaction sweep closed secret leaks across terminal errors, environment file reads, and checkpoints. And macOS permission grants survive updates.
