versioning

Repository rules for releasing and updating several related libraries. They require semantic versioning, a system where version numbers show the type of change made.

In plain words
What is it for?
Use them when changing library code, choosing a new version number, or updating the minimum version required by another library after a breaking change.
Why use it?
They help prevent users from receiving incompatible library combinations or outdated dependency requirements after code changes.

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

versioning 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

Versioning

This repository contains 5 libraries: arcade-core, arcade-tdk, arcade-serve, arcade-mcp-server, and arcade-mcp (CLI)

Dependency graph recap:

  1. arcade-core
    • The base library
  2. arcade-tdk
    • Depends on: arcade-core
  3. arcade-serve
    • Depends on: arcade-core
  4. arcade-mcp-server
    • Depends on: arcade-core, arcade-serve, arcade-tdk
  5. arcade-mcp
    • Depends on: arcade-mcp-server, arcade-core
    • Dev/optional deps: arcade-serve, arcade-tdk

Rules

  • ALWAYS use semver (semantic versioning)
  • ALWAYS increase the version of a library in pyproject.toml when a library's code is modified.
  • ALWAYS increase the minimum required version of dependencies if there is a breaking change between dependencies
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.
