nanobot is a small, self-hosted personal AI agent framework written in Python, providing an agent runtime that can operate through a WebUI, terminal, or chat applications. Users use it to connect language models with tools, memory, MCP integrations, scheduled automation, and multi-agent workflows. The catalogue add-ons provide skills and instructions for working with nanobot.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00019 | $0.00301 |
| Opus 5.5 | $0.00008 | $0.00120 |
| Sonnet 5.5 | $0.00004 | $0.00060 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade A, and why
nanobot-document 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 3d 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.
What it actually says
nanobot Documentation
Use the documentation in references/ beside this skill. It ships with the installed version of nanobot. Load only the material needed for the user's question.
| Topic | Entry point |
|---|---|
| Setup | Quick start |
| WebUI | WebUI |
| Provider setup | Provider cookbook |
| Provider/model behavior | Providers |
| Exact fields and defaults | Configuration |
| Chat apps and integrations | Task guides |
| Errors | Troubleshooting |
| Other topics | Documentation index |
Prefer documented WebUI steps when the setting has a graphical control, unless headless or config-file setup is requested. Configuration examples are partial snippets to merge unless stated otherwise.
Bundled docs match this installation's source and may be newer than the stable release. For latest-release questions or missing bundled docs, consult the published documentation and make any version mismatch explicit. Links leaving references/ refer to repository files that may not be bundled.
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.

nanobot-document is a skill published in the GitHub repository HKUDS/nanobot (49,064 stars, last pushed today), licensed MIT. It adds 19 tokens to every session and 301 once invoked, about $0.0001 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 2026-10-13.
