dev

A command that starts or reuses Notabene's review server for the current code repository and prints its web address.

In plain words
What is it for?
It is for opening a Notabene review page while working on a repository.
Why use it?
It avoids manually starting the server and prevents multiple copies from running for the same repository.

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.

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

dev 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 2d 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

Start the notabene review server for this repo as a detached daemon and report the URL. Idempotent — if one is already running for this repo it just prints the existing URL. The first run fetches the renderer (~30 s); after that it's fast. Then it returns (the server keeps running in the background).

!node "${CLAUDE_PLUGIN_ROOT}/bin/nb.mjs" dev --detach $ARGUMENTS

Report the URL from the output. If it says the port isn't responding yet, tell the user to check the log path shown, or re-run /notabene:status.

Changes

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.
