Automated safety checks
This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.
Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

About this skill
The m03-mutability skill enables AI agents to handle mutable state within Rust applications, allowing them to modify variables and data structures during execution. It provides the necessary logic to manage ownership rules and borrowing constraints effectively in dynamic workflows.
When to use it
- Implementing algorithms that require updating loop counters or accumulating results in a single variable.
- Managing configuration states that need to change based on runtime conditions or user inputs.
- Building interactive tools where the application's internal data model must evolve over time.
- Developing simulations where entity properties, such as position or health, are frequently updated.
Key capabilities
- Safe modification of owned values and references within Rust code.
- Enforcement of borrowing rules to prevent data races during state changes.
- Integration with the Actionbook ecosystem for Rust-based AI agent tasks.
Example prompts
- "Create a Rust function that updates a user's score in a game loop using mutable references."
- "Write code to dynamically adjust a configuration object based on incoming sensor data."
- "Implement a simulation where an agent's position changes every frame using mutable state."
Tips & gotchas
Ensure you understand Rust's ownership and borrowing system before utilizing this skill, as improper use can lead to compile-time errors. This skill is specifically designed for the Actionbook environment; it may not function in standard Rust projects without additional context.
