What it does

Remove Crate Prefix is an agent skill from r3bl-org/r3bl-open-core. Enforce the "Clean Imports over Inline Absolute Paths" rule by removing inline crate:: prefixes and adding proper use statements.

Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. The repository describes itself as: TUI framework and developer productivity apps in Rust 🦀. The licence is Apache-2.0.

When your agent uses it

  • Development work in your project

Example prompts

  • “Clean Imports over Inline Absolute Paths”
  • “/remove-crate-prefix”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Determine Target Files
  2. Scan the targeted file(s) for instances of inline crate:: usage for types.
  3. Group the required imports into a single use crate::{...}; statement.
  4. Remove the crate:: prefix from the inline usages.
  5. Verify the changes compile successfully using ./check.fish --check.

What it can do on your machine

Read from SKILL.md and the folder at commit 89db352. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Remove Crate Prefix loads about 600 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 291 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~600

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Enforce the "Clean Imports over Inline Absolute Paths" rule by removing inline crate:: prefixes and adding proper use statements.

Remove Crate Prefix Skill

Purpose

This skill enforces the "Clean Imports over Inline Absolute Paths (Mandatory)" rule defined in the project's AGENTS.md. It automatically scans code for inline crate:: prefixes (e.g. crate::Type, crate::Size) and refactors the code to use clean imports at the top of the file or scope.

Rules

Do NOT write absolute inline paths like crate::Type or crate::Size inside function signatures or bodies.

✅ Good:
rust
use crate::{Size, Pos};

pub fn render(size: Size) -> Pos { ... }
❌ Bad:
rust
pub fn render(size: crate::Size) -> crate::Pos { ... }

Exceptions

  • Declarative Macros (macro_rules!): Do NOT apply this refactor inside declarative macros, and NEVER touch or remove the $crate:: prefix. Modifying $crate:: will result in a syntax error because it turns a built-in macro keyword into an undeclared macro variable.
  • Macro invocations often require absolute paths (e.g., crate::key_press!). This rule primarily targets structs, traits, and enums (e.g., crate::ModifierKeysMask).
  • Sometimes in generated code or highly isolated scopes, a use crate::{...} block directly inside a function or if block is preferred over a file-level import to minimize scope pollution.

Execution

When invoked:

  1. Determine Target Files:
    • If specific files are provided as arguments, target those files.
    • If no arguments are supplied, find all modified staged and unstaged files (e.g., via git diff --name-only and git diff --cached --name-only) and target all of them.
  2. Scan the targeted file(s) for instances of inline crate:: usage for types.
  3. Group the required imports into a single use crate::{...}; statement.
    • For production code: Place the use statement at or near the top of the file, joining existing file-level imports (even if the crate:: usage is inside an inner module).
    • For test code: The use statement can be added to the closest inner test module where the other test imports are located.
  4. Remove the crate:: prefix from the inline usages.
  5. Verify the changes compile successfully using ./check.fish --check.
