Antfarm is a workflow tool for OpenClaw that coordinates specialized AI agents, such as planners, developers, testers, verifiers, and reviewers, to complete software tasks together. It is used for repeatable feature development, security audits, and bug fixes that produce tested pull requests. The catalogue add-on provides Antfarm-related agent instructions and skills.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00582 | $0.00582 |
| Opus 5.5 | $0.00233 | $0.00233 |
| Sonnet 5.5 | $0.00116 | $0.00116 |
| Haiku 4.5 | $0.00058 | $0.00058 |
Grade A, and why
antfarm AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Antfarm Agents
Antfarm provisions multi-agent workflows for OpenClaw. It installs workflow agent workspaces, wires agents into the OpenClaw config, and keeps a run record per task.
Installing Antfarm
Prerequisites: Node.js >= 22, OpenClaw v2026.2.9+, gh CLI (for PR steps).
Do NOT run
npm install antfarm. There is an unrelated package on npm with that name. Antfarm is installed from GitHub only.
Steps
-
Clone the repo into the OpenClaw workspace:
git clone https://github.com/snarktank/antfarm.git ~/.openclaw/workspace/antfarm -
Build:
cd ~/.openclaw/workspace/antfarm npm install npm run build -
Link the CLI (makes
antfarmavailable globally):npm link -
Install workflows (provisions agents, cron jobs, and DB):
antfarm install -
Verify: Run
antfarm workflow list— you should see the available workflows.
If antfarm fails with a node:sqlite error, your node binary may be Bun's wrapper instead of real Node.js 22+. Check with node -e "require('node:sqlite')". See #54 for workarounds.
Why Antfarm
- Repeatable workflow execution: Start the same set of agents with a consistent prompt and workspace every time.
- Structured collaboration: Each workflow defines roles (lead, developer, verifier, reviewer) and how they hand off work.
- Traceable runs: Runs are stored by task title so you can check status without hunting through logs.
- Clean lifecycle: Install, update, or uninstall workflows without manual cleanup.
What It Changes in OpenClaw
- Adds workflow agents to
openclaw.json(your main agent stays default). - Creates workflow workspaces under
~/.openclaw/workspaces/workflows. - Stores workflow definitions and run state under
~/.openclaw/antfarm. - Inserts an Antfarm guidance block into the main agent's
AGENTS.mdandTOOLS.md.
Uninstalling
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

antfarm AGENTS.md is an instructions file published in the GitHub repository snarktank/antfarm (2,494 stars, last pushed 8mo ago), licensed MIT. It adds 582 tokens to every session, about $0.0023 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
