NanoClaw is an AI assistant that runs agents inside separate Linux containers, isolating their files and execution environments. People use it to connect agents to messaging services and run assistants with memory and scheduled jobs. The catalogue contains skills and instructions for extending or operating NanoClaw.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

- NVIDIA SkillSpector warn
SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00065 | $0.04323 |
| Opus 5.5 | $0.00026 | $0.01729 |
| Sonnet 5.5 | $0.00013 | $0.00865 |
| Haiku 4.5 | $0.00006 | $0.00432 |
Grade A, and why
add-opencode 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 yesterday.
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 — 345 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenCode agent provider
Install OpenCode as an optional NanoClaw runtime. The payload is included in this skill; it needs no separate provider branch. It uses the upstream runtime, instructions, host, and setup metadata contracts. The host contract remains at version 1; the container owns its non-secret ChatGPT placeholder file.
OpenCode is offered by the standard setup provider picker. Existing installs can
add or authenticate it with pnpm exec tsx setup/index.ts --step provider-auth opencode.
To replace an installed payload and update its pins, append --refresh; back up
local payload edits first. Ordinary re-authentication leaves installed files and
the container image alone. Backend defaults are installation-wide; model and
reasoning effort can be overridden per group through the existing container
configuration. Per-group backend/auth selection and structured channel attachment
transport are separate work.
Authentication checks the installed files, registration lines, and exact pins against this skill's declarations without launching a subprocess or container. Install and refresh run the existing provider contract verification; the build step owns image freshness. Model selection does not repeat installation checks. A working backend and account are checked separately by sending a real request.
Install
After installing this payload, run pnpm exec tsx scripts/opencode-host.ts --configure
for host OpenCode setup, or use --update / --debug for the corresponding
operational skill. An existing OpenCode CLI can also run directly in the checkout;
it discovers .claude/skills natively. Host sign-in uses OpenCode's own settings
and is independent of the container's gateway credentials. Installed setup failures
use the existing provider failure-assist hook, including wizard authentication
and installation-check failures. Host diagnostic context is model input and may
remain in native OpenCode history; deleting its private temporary file does not
erase those records. The helper requires stable OpenCode 1.18.25 or newer with
--prompt and prefers the newest compatible installation it finds.
--debug, --update and failure help launch it with an OPENCODE_PERMISSION
override, so OpenCode asks before every edit and command even when the
operator's top-level config allows them (OpenCode itself skips the prompt for
a bare redirection with no command, such as > file). --configure keeps
OpenCode's native permissions.
Automatic help before payload
installation is optional and is not part of the runtime contract.
What ships with it
41 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

add-opencode is a skill published in the GitHub repository nanocoai/nanoclaw (30,980 stars, last pushed today), licensed MIT. It adds 65 tokens to every session and 4,323 once invoked, about $0.0003 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.
