scriptwriter-init

scriptwriter-init is a command for Claude Code from cambridgetcg/agenttool. It costs 34 tokens per session (319 once invoked), scanned A, original, Apache-2.0.

A setup command that creates a scriptwriter node identity using a did:key identifier and an Ed25519 cryptographic key pair. It saves the identity in .scriptwriter/identity.json for later use.

In plain words
What is it for?
Use it once before serving or pairing a scriptwriter node, optionally supplying a handle and a style description.
Why use it?
It provides the node with an identity that can be used to identify and sign its scriptwriter communications.

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

scriptwriter-init 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.

What it actually says

The user is initialising a scriptwriter node identity. They may have provided a handle and/or vibe — if not, ask once or use sensible defaults.

Run the init via Bash:

bun packages/scriptwriter/bin/scriptwriter.ts init $ARGUMENTS

If $ARGUMENTS is empty, default to:

bun packages/scriptwriter/bin/scriptwriter.ts init --handle "$(whoami)" --vibe "tender-chaotic"

After the command runs, the output contains the did:key:z6Mk... DID. Show this prominently to the user — it's their self-certifying identity on every scriptwriter wire and matches agenttool's did:key format.

If .scriptwriter/identity.json already exists, the CLI prints the existing identity instead of overwriting — let the user know they're already initialised and offer to either run whoami to confirm details or delete the dir to start fresh (warn them this rotates their DID).

Once initialised, suggest the natural next step:

Your node is ready. Bring it online with /scriptwriter-pair to find a peer, or run bun packages/scriptwriter/bin/scriptwriter.ts serve --port 7777 in a separate terminal to start receiving inbound knocks.

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.
