Octomind is a CLI-first AI coding agent runtime. It gives an LLM real access to your repo — reading and writing files, running shells, searching code, delegating to sub-agents — through MCP tools. The same session engine works interactively, piped through stdin, as a background daemon, over WebSocket, or as an ACP sub-agent inside another agent's stack.
octomind run developer:general
echo "Explain the auth module" | octomind run developer:general --format plain
echo "watch the build" | octomind run --name watcher --daemon --format jsonl
octomind send --name watcher "run the test suite"
Most coding agents assume a human is watching the screen. Octomind is built for the work that keeps going after you leave.
- Policy as code, not approval popups. Deterministicguardrails — pre-call guards, post-result hooks, post-turn validators — live in TOML and scripts, so they work in CI, daemons, and scheduled runs.
- Proven on real PRs. It solved 24 of 25 held-out tasks at lower cost than the closest competitor. See thebenchmarks .
- Ready-made specialists.
octomind run developer:generalpulls a packaged agent (prompt, model, MCP servers, tool permissions) from atap . Publish your own with one repo. - Sessions that stay sharp. Adaptivecompression keeps long tasks moving while retaining task knowledge and the live exchange.
- Any model, any budget. Use Octomind Cloud or your own key (OpenRouter, Anthropic, OpenAI, DeepSeek, Ollama, and more), pick a model per role, and set spend thresholds per request and per session. A request over its threshold stops; at the session threshold a terminal session asks y/N before continuing, while a non-interactive
octomind runstops with exit code 75. - One config. Models, tools, roles, guardrails, budgets: all TOML, no framework code.
1. Install (macOS, Linux):
curl -fsSL https://raw.githubusercontent.com/muvon/octomind/master/install.sh | bash
On Windows, in PowerShell:
irm https://raw.githubusercontent.com/muvon/octomind/master/install.ps1 | iex
On macOS, you can also install with Homebrew:
brew install muvon/tap/octomind
2. Get model access. The fastest path is Octomind Cloud, which includes models and needs no configuration:
octomind login
Prefer your own provider key? Skip login and export one (also OPENAI_API_KEY, ANTHROPIC_API_KEY, DEEPSEEK_API_KEY), then follow Model access to point the config at it:
export OPENROUTER_API_KEY="your_key"
3. Run a specialist in your project:
cd ~/your/project
octomind run developer:general
You're now in a session with an agent that can read your code, run commands, and edit files. The interface is a plain line prompt with markdown rendering — no TUI to learn, so it works over SSH, in tmux, and in CI logs. The first time you run a specialist, it may install its tools and ask for credentials.
developer:general comes from the default tap muvon/tap, not your local config. Plain octomind run starts the config's default role, assistant:concierge.
Try the recorded bug-fix demo: two failing tests, an agent fix, and an independent test rerun.
Measured on octobench against 25 tasks harvested from merged pull requests across Python, PHP, Rust, C++, and JavaScript. Each agent works in the pre-fix repo; held-out tests from the merged fix decide pass or fail. These are the published July 30, 2026 results, not a measurement of this checkout.
| solved | judge Σ / 2500 | cost | wall time | |
|---|---|---|---|---|
| octomind + glm-5.2 | 24/25 | 2264 | $63.43 | 3.6h |
| claude code + claude-opus-5 | 23/25 | 2262 | $81.79 | 6.7h |
| codex + gpt-5.6-sol | 21/25 | 2127 | $14.86 | 1.0h |
| opencode + glm-5.2 | 19/25 | 2093 | $129.54 | 3.3h |
- The harness matters. opencode used the same model and endpoint; octomind solved 24 vs 19 at roughly half the cost. All four agents ran stock invocations with no tuning, so this measures the whole harness, not individual features.
- Worst-case pricing, still ahead. glm-5.2 ran without prompt caching while Opus billed ~97% of context re-reads at cache rates — and octomind still led on solves, cost, and wall time.
- Reproducible. Per-case table, artifacts, and reproduction guide:BENCHMARK.md . Background:blog post .
Drop a .agents/guardrails.toml in your repo. The runtime enforces it deterministically, with no code to compile and no plugin to install.
[[guard]]
match = "shell(command=^rm\\s+-rf?)"
message = "rm -rf blocked."
[[guard]]
match = "shell(command=git push)"
when = ["+shell(command=git status)"]
message = "Review changes before pushing."
| Layer | When it runs | What it does |
|---|---|---|
| Guards | Before a tool call | Deny by capability, argument regex, and session history. A match returns a denial instead of executing the call. |
| Hooks | After a tool result | A non-zero exit injects stdout into the agent's inbox — lint and format failures become automatic corrections without restarting the turn. |
| Validators | After a turn | Scripts the agent reads on its next turn. This replaces "approve this change?" prompts in autonomous loops. |

octomind run developer:general # general dev, language skills auto-activate
octomind run doctor:blood # blood-test interpretation specialist
octomind run lawyer:sg # legal specialist
Running a specialist fetches its manifest from the tap registry, installs any required binaries, resolves credentials, starts the right MCP servers, and then opens the session.
Build and register your own:
octomind tap init yourteam/my-tap # scaffold, validate, git-init, and register locally
octomind tap yourteam/my-tap # on another machine, after publishing to GitHub
The octomind- prefix is added automatically: yourteam/my-tap maps to the repository
yourteam/octomind-my-tap.

The install script detects your OS and architecture (Linux and macOS on x86_64/aarch64) and installs to ~/.local/bin/. Pass --install-dir <DIR> or set OCTOMIND_INSTALL_DIR to override. On Windows (x86_64/aarch64), install.ps1 installs to %LOCALAPPDATA%\octomind\bin and adds it to your user PATH; it honors OCTOMIND_INSTALL_DIR and OCTOMIND_VERSION too. install.sh still works from Git Bash or MSYS2.
Command not found? Add the install directory to your PATH:
export PATH="$HOME/.local/bin:$PATH"
Building from source requires protoc; see Building from source for per-OS prerequisites.

Octomind Cloud — octomind login (device-code sign-in, like gh auth login) stores a gateway key locally. The default config already uses octohub:auto. Learn more.
Bring your own key — set the provider's environment variable (OPENROUTER_API_KEY, OPENAI_API_KEY, ANTHROPIC_API_KEY, DEEPSEEK_API_KEY, …) and point the model tables at it. The supervisor and compression profiles also default to octohub:auto, so update all three:
[model]
name = "openrouter:google/gemini-2.5-flash"
[supervisor.model]
name = "openrouter:google/gemini-2.5-flash"
[compression.model]
name = "openrouter:google/gemini-2.5-flash"
Provider details and per-role overrides: Providers & models.
Config lives at ~/.local/share/octomind/config/config.toml on macOS and Linux, and under %LOCALAPPDATA%/octomind/config/ on Windows. Set OCTOMIND_DATA_DIR to override the data root.
octomind config --show # view current config
octomind config --validate # validate config
Override any value for a single run with -c:
octomind run -c supervisor.enabled=false

Octomind reports anonymous usage: which commands, tools, and models are used, plus timings, token counts, and error kinds. It never sends your code, prompts, file paths, tool arguments, or environment values. Opt out in any of three ways:
export DO_NOT_TRACK=1 # the cross-tool standard, honored first
export OCTOMIND_TELEMETRY=0 # for subsequent commands in this shell
