package-creation

A guide for adding a new publishable package to the Rozenite project, including its documentation, package metadata, and library entry points.

In plain words
What is it for?
Use it to prepare a package README and package.json, define its import and type entry points, and run the required checks.
Why use it?
It helps a new package match the repository's existing structure so it can be built, published, and used consistently.

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.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 152 The whole file, excluding the scripts and references it only reads on demand.

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

package-creation 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 today.

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

New packages

  • Compare with similar packages under packages/.
  • README must follow the shared repository structure:
    • banner
    • tagline
    • badges
    • description
    • features or exports
    • installation
    • usage
    • Callstack footer and link definitions
  • Copy standard package.json metadata:
    • homepage
    • bugs
    • repository
    • author
    • license
    • publishConfig
    • files
  • Library packages must also define matching main, module, types, and exports fields.
  • Use package-specific npm links in README badges and links.
  • Run formatting and package checks before opening a PR.

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.

package-creation is an agent published in the GitHub repository callstackincubator/rozenite (653 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 152 tokens. 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 2026-08-31.
