update-setup

A one-time setup wizard for creating a personalised upgrade skill in a nanobot agent workspace. It checks whether an upgrade skill already exists and gathers version and installation details.

In plain words
What is it for?
Preparing nanobot's upgrade instructions and identifying how nanobot is currently installed.
Why use it?
It guides the setup process and helps avoid overwriting an existing upgrade skill without confirmation.

Token cost

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.

Security

Grade A, and why

update-setup 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Update Setup

Generate a personalized upgrade skill in Nanobot's agent workspace.

Use the absolute <agent-workspace>/skills/update/SKILL.md path, where <agent-workspace> is shown in the system prompt. Never substitute a project-relative path. If the write is rejected, ask the user to select the agent workspace or enable Full Access before rerunning setup.

Step 1: Check Existing

Use read_file to check if <agent-workspace>/skills/update/SKILL.md already exists.

If it exists, ask the user: "An upgrade skill already exists. Reconfigure?" Wait for the user's reply. If no, stop here.

Step 2: Current Version and Install Clues

Use exec to run nanobot --version. Tell the user the current version.

Then collect install clues with exec. These commands are best-effort; if one fails, keep going and show the useful output:

command -v nanobot || true
python -m pip show nanobot-ai || true
pipx list | sed -n '/nanobot-ai/,+3p' || true
uv tool list | sed -n '/nanobot-ai/,+3p' || true

Summarize what you found in one short paragraph. Use the clues only to suggest a likely install method. Do not treat them as confirmation.

Step 3: Confirm Required Inputs

CRITICAL: Do not write <agent-workspace>/skills/update/SKILL.md until the install method is explicitly confirmed by the user. The install method must come from a user answer or confirmation, not from inference alone. If you cannot get a clear answer, stop and ask the user to rerun this setup when they know how nanobot was installed.

Ask the user the questions below, one at a time, in your response text. Wait for the user's reply before proceeding to the next question. If you cannot get a clear answer, stop without writing the skill.

Question 1 — Install method:

question: "I found these install clues: <SUMMARY>. Which update method should this workspace use?"
options: ["uv", "pipx", "pip", "source (git clone)", "not sure"]

If the user selected not sure, explain the difference between the options and stop. Do not generate the upgrade skill.

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.
