prompt-init

prompt-init is a command for coding agents from assist-software/claude-code-repository. It costs 48 tokens per session (1,359 once invoked), scanned C, original, no licence file.

A project setup command for organising prompt-engineering files, meaning files that guide an AI model's behaviour. It creates folders for rules and features, plus a summary of existing prompts.

In plain words
What is it for?
Run it once in a project to start managing its prompts; it can also be run again safely.
Why use it?
It removes the need to create this documentation structure and inventory by hand.

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 C, and why

prompt-init scanned grade C with 1 finding 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

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.
