The dispatcher's circuit breaker only protected against spawn-side
failures (profile missing, workspace mount error, exec failure).
Workers that successfully spawned but then timed out or crashed
re-queued to ``ready`` with no counter increment, so the next tick
re-spawned them — loops forever until someone noticed. Reported
externally on Twitter (Forbidden Seeds) and confirmed by walking the
kernel: ``enforce_max_runtime`` flipped the task back to ready, emitted
a ``timed_out`` event, and never touched ``spawn_failures``; same for
``detect_crashed_workers``.
Fix: unify the counter across all non-success outcomes.
Schema
------
* ``tasks.spawn_failures`` → ``tasks.consecutive_failures``
* ``tasks.last_spawn_error`` → ``tasks.last_failure_error``
* Migration renames the columns in-place on existing DBs (``ALTER
TABLE RENAME COLUMN`` — SQLite >= 3.25) so historical counter
values are preserved. Row mappers fall through to the legacy names
if both column renames and a migration somehow got out of sync.
Counter lifecycle
-----------------
New helper ``_record_task_failure(conn, task_id, error, *, outcome,
release_claim, end_run, event_payload_extra)`` is the single point
every non-success outcome funnels through:
* ``spawn_failed`` → ``_record_spawn_failure`` (kept as alias)
calls it with ``release_claim=True, end_run=True`` — transitions
running→ready, clears claim, closes run.
* ``timed_out`` → ``enforce_max_runtime`` already does the status
transition + run close + event emission, then calls
``_record_task_failure`` with ``release_claim=False, end_run=False``
just to bump the counter (and trip the breaker if needed).
* ``crashed`` → ``detect_crashed_workers`` same pattern, but the
counter increment runs after the main write_txn closes (SQLite
doesn't nest write transactions).
If the counter hits the breaker threshold (``DEFAULT_FAILURE_LIMIT=5``,
same as before), the task transitions to ``blocked`` with a ``gave_up``
event on top of whatever outcome-specific event was already emitted.
Reset semantics changed: the counter now clears only on successful
``complete_task`` (and operator ``reclaim_task`` — an explicit "I've
looked at this, try again with a fresh budget"). Previously
``_clear_spawn_failures`` ran on every successful spawn, which would
have wiped the counter before a timeout could accumulate past threshold
— exactly the loop this fix prevents.
Diagnostics
-----------
* ``_rule_repeated_spawn_failures`` → ``_rule_repeated_failures``. Now
fires regardless of which outcome is at fault. Classifies the most
recent failure (spawn_failed / timed_out / crashed) from the run
history so the title ("Agent timeout x3", "Agent crash x4", "Agent
spawn x5") and suggested action (``doctor`` for spawn, ``log`` for
timeout/crash) stay outcome-specific without N duplicate rules.
* ``_rule_repeated_crashes`` kept as a narrower early-warning at
threshold 2 (vs 3 for the unified rule), but now suppresses itself
when the unified rule would also fire — avoids double-flagging.
* Diagnostic ``data`` payload now carries
``{consecutive_failures, most_recent_outcome, last_error}`` instead
of spawn-specific keys.
CLI
---
* ``Task.consecutive_failures`` / ``Task.last_failure_error`` are the
public fields now. Existing callers that referenced the old names
get migrated (tests updated in this commit).
* Backward-compat: ``DEFAULT_SPAWN_FAILURE_LIMIT``,
``_clear_spawn_failures``, ``_record_spawn_failure`` stay as aliases.
Tests
-----
* 6 new kernel tests: timeout increments counter, 3 consecutive
timeouts trip the breaker (was the reported gap), crash increments
counter, reclaim clears counter, completion clears counter, spawn
success does NOT clear counter.
* Diagnostic tests: updated ``repeated_spawn_failures`` cases to use
the new kind name and add a timeout-loop test.
* Dashboard API test: spawn_failures column update → consecutive_failures.
389/389 kanban-suite tests pass.
Live verification
-----------------
Seeded 4 tasks in an isolated HERMES_HOME: 3 timeouts, 4 crashes,
2-spawn-failed + 2-timed-out, and a task that had prior failures but
completed successfully. Board correctly shows "!! 3 tasks need
attention" (the successful one has no badge because the counter
reset). Drawer for the timeout-loop task renders "Agent timeout x3"
with most_recent_outcome=timed_out and the "Check logs" suggested
action (not the spawn-flavoured "Verify profile"). The successful
task has zero diagnostics.
Closes the Forbidden-Seeds-reported gap.

Hermes Agent ☤
The self-improving AI agent built by Nous Research. It's the only agent with a built-in learning loop — it creates skills from experience, improves them during use, nudges itself to persist knowledge, searches its own past conversations, and builds a deepening model of who you are across sessions. Run it on a $5 VPS, a GPU cluster, or serverless infrastructure that costs nearly nothing when idle. It's not tied to your laptop — talk to it from Telegram while it works on a cloud VM.
Use any model you want — Nous Portal, OpenRouter (200+ models), NVIDIA NIM (Nemotron), Xiaomi MiMo, z.ai/GLM, Kimi/Moonshot, MiniMax, Hugging Face, OpenAI, or your own endpoint. Switch with hermes model — no code changes, no lock-in.
| A real terminal interface | Full TUI with multiline editing, slash-command autocomplete, conversation history, interrupt-and-redirect, and streaming tool output. |
| Lives where you do | Telegram, Discord, Slack, WhatsApp, Signal, and CLI — all from a single gateway process. Voice memo transcription, cross-platform conversation continuity. |
| A closed learning loop | Agent-curated memory with periodic nudges. Autonomous skill creation after complex tasks. Skills self-improve during use. FTS5 session search with LLM summarization for cross-session recall. Honcho dialectic user modeling. Compatible with the agentskills.io open standard. |
| Scheduled automations | Built-in cron scheduler with delivery to any platform. Daily reports, nightly backups, weekly audits — all in natural language, running unattended. |
| Delegates and parallelizes | Spawn isolated subagents for parallel workstreams. Write Python scripts that call tools via RPC, collapsing multi-step pipelines into zero-context-cost turns. |
| Runs anywhere, not just your laptop | Seven terminal backends — local, Docker, SSH, Singularity, Modal, Daytona, and Vercel Sandbox. Daytona and Modal offer serverless persistence — your agent's environment hibernates when idle and wakes on demand, costing nearly nothing between sessions. Run it on a $5 VPS or a GPU cluster. |
| Research-ready | Batch trajectory generation, Atropos RL environments, trajectory compression for training the next generation of tool-calling models. |
Quick Install
curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash
Works on Linux, macOS, WSL2, and Android via Termux. The installer handles the platform-specific setup for you.
Android / Termux: The tested manual path is documented in the Termux guide. On Termux, Hermes installs a curated
.[termux]extra because the full.[all]extra currently pulls Android-incompatible voice dependencies.Windows: Native Windows is not supported. Please install WSL2 and run the command above.
After installation:
source ~/.bashrc # reload shell (or: source ~/.zshrc)
hermes # start chatting!
Getting Started
hermes # Interactive CLI — start a conversation
hermes model # Choose your LLM provider and model
hermes tools # Configure which tools are enabled
hermes config set # Set individual config values
hermes gateway # Start the messaging gateway (Telegram, Discord, etc.)
hermes setup # Run the full setup wizard (configures everything at once)
hermes claw migrate # Migrate from OpenClaw (if coming from OpenClaw)
hermes update # Update to the latest version
hermes doctor # Diagnose any issues
CLI vs Messaging Quick Reference
Hermes has two entry points: start the terminal UI with hermes, or run the gateway and talk to it from Telegram, Discord, Slack, WhatsApp, Signal, or Email. Once you're in a conversation, many slash commands are shared across both interfaces.
| Action | CLI | Messaging platforms |
|---|---|---|
| Start chatting | hermes |
Run hermes gateway setup + hermes gateway start, then send the bot a message |
| Start fresh conversation | /new or /reset |
/new or /reset |
| Change model | /model [provider:model] |
/model [provider:model] |
| Set a personality | /personality [name] |
/personality [name] |
| Retry or undo the last turn | /retry, /undo |
/retry, /undo |
| Compress context / check usage | /compress, /usage, /insights [--days N] |
/compress, /usage, /insights [days] |
| Browse skills | /skills or /<skill-name> |
/<skill-name> |
| Interrupt current work | Ctrl+C or send a new message |
/stop or send a new message |
| Platform-specific status | /platforms |
/status, /sethome |
For the full command lists, see the CLI guide and the Messaging Gateway guide.

Migrating from OpenClaw
If you're coming from OpenClaw, Hermes can automatically import your settings, memories, skills, and API keys.
During first-time setup: The setup wizard (hermes setup) automatically detects ~/.openclaw and offers to migrate before configuration begins.
Anytime after install:
hermes claw migrate # Interactive migration (full preset)
hermes claw migrate --dry-run # Preview what would be migrated
hermes claw migrate --preset user-data # Migrate without secrets
hermes claw migrate --overwrite # Overwrite existing conflicts
What gets imported:
- SOUL.md — persona file
- Memories — MEMORY.md and USER.md entries
- Skills — user-created skills →
~/.hermes/skills/openclaw-imports/ - Command allowlist — approval patterns
- Messaging settings — platform configs, allowed users, working directory
- API keys — allowlisted secrets (Telegram, OpenRouter, OpenAI, Anthropic, ElevenLabs)
- TTS assets — workspace audio files
- Workspace instructions — AGENTS.md (with
--workspace-target)
See hermes claw migrate --help for all options, or use the openclaw-migration skill for an interactive agent-guided migration with dry-run previews.
Contributing
We welcome contributions! See the Contributing Guide for development setup, code style, and PR process.
Quick start for contributors — clone and go with setup-hermes.sh:
git clone https://github.com/NousResearch/hermes-agent.git
cd hermes-agent
./setup-hermes.sh # installs uv, creates venv, installs .[all], symlinks ~/.local/bin/hermes
./hermes # auto-detects the venv, no need to `source` first
Manual path (equivalent to the above):
curl -LsSf https://astral.sh/uv/install.sh | sh
