Install target

Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

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.

  • Pinned to a commit: passed

    Scanned actionbook/rust-skills at 5c40d3ad78.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

1 file, 165 lines
This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

The M09 Domain skill assists in structuring data and designing software based on Domain-Driven Design (DDD) principles, specifically within a Rust programming context. It helps define domain concepts by determining whether they should be modeled as Entities (with unique identities), Value Objects (interchangeable values), or Aggregates (groups of related objects). The skill provides guidance on invariants, ownership implications, and mapping these concepts to appropriate Rust patterns and code structures.

When to use it

  • When designing a new software system based on Domain-Driven Design principles.
  • To determine whether a specific data concept should be modeled as an Entity or Value Object.
  • For establishing aggregate boundaries within a domain model.
  • To define validation rules and invariants for domain objects.
  • When needing to translate domain concepts into Rust code patterns (structs, traits, enums).

Key capabilities

  • Entity vs. Value Object Identification: Determines if a concept requires a unique identity or can be treated as an interchangeable value.
  • Aggregate Boundary Definition: Helps identify groups of objects that must maintain consistency together.
  • Invariant Specification: Guides the definition of rules and constraints that domain objects must adhere to.
  • Rust Pattern Mapping: Provides guidance on translating DDD concepts into corresponding Rust code patterns (e.g., structs, traits, enums).
  • Ownership Guidance: Offers advice on ownership implications for different modeling choices (owned, shared, weak references).

Example prompts

  • "Should 'Customer' be modeled as an Entity or a Value Object?"
  • "What are the invariants that must hold for a 'Transaction'?"
  • "How do I model this concept in Rust using DDD principles?"
  • “What is the best way to define ownership for these related objects?”

Tips & gotchas

  • This skill focuses on design choices within a Domain-Driven Design context, specifically when implementing in Rust. It does not provide implementation details beyond pattern suggestions.
  • Understanding basic DDD concepts (Entities, Value Objects, Aggregates) is helpful to effectively utilize this skill.
