Migrate Core Code to Submodules
tinyhumansai/openhuman
Plans and carries out moving non-host-specific code and its tests from the OpenHuman core into vendored tiny submodule libraries, then releases the submodule and re-pins the host.
Propose or implement Rust refactors for a specific coupling finding or requested structural change.

What it does
Refactor is an agent skill from nwiizo/cargo-coupling. Propose or implement Rust refactors for a specific coupling finding or requested structural change. Use when changes are requested, not for a diagnosis-only review.
Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `patterns.md`).
It sits in Development, covering Refactoring. It works with Rust. The repository describes itself as: A coupling analysis tool for Rust projects - measuring the 'right distance' in your code. The licence is MIT.
When your agent uses it
- Changes are requested
- Not for a diagnosis-only review
Example prompts
- “/refactor”
What it can do on your machine
Read from SKILL.md and the folder at commit 8ef1441. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Refactor loads about 511 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 243 words of instructions outside code blocks.
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.

Refactor Coupling
Use the user's finding or a current analysis to identify the change in scope. If analysis is needed, follow analyze. Treat issue-type labels as review filters, not CLI arguments.
Confirm the problem in the implementation and callers. Prefer the smallest change that reduces shared knowledge or change impact while preserving behavior. Existing entrypoints, re-export facades, and stable hubs may be appropriate. Use patterns.md only for a relevant example, not as a required design.
For proposal requests, explain the problem, recommendation, and validation plan; include before/after code or migration steps when they help assess the change. For implementation requests, carry out the authorized change and verification without stopping after the proposal. Resolve only material unanswered choices.
Apply the repository's Rust structural-analysis guidance, using
similarity for duplicate candidates and cargo-coupling
for boundary effects. Inspect findings before extracting abstractions; retain
similar code when the responsibilities or reasons to change differ.
Compare the affected behavior and analysis with the same settings and Git history.
Preserve input validation and error handling. Characterize uncovered behavior
before a behavior-preserving refactor; such a test should pass on the old code.
For a bug fix, first demonstrate the bug with a failing regression test when a
practical test seam exists. Run relevant tests and required
repository checks; repeat passing checks only after a relevant change or failure.
Complete with the actual change, verification results, and remaining limitations. Commit or push when requested; a refactor request alone does not authorize either.

What does Refactor do?
Propose or implement Rust refactors for a specific coupling finding or requested structural change. Refactor is an agent skill from nwiizo/cargo-coupling. Propose or implement Rust refactors for a specific coupling finding or requested structural change.
When should I use Refactor?
Refactor fits situations like: changes are requested; not for a diagnosis-only review.
How do I install Refactor in Claude Code?
Run `npx skills add nwiizo/cargo-coupling --skill refactor -a claude-code`. Or copy the skill folder (.agents/skills/refactor in nwiizo/cargo-coupling) into .claude/skills/refactor in your project. Claude Code loads it when a task matches its description.
How do I install Refactor in Codex?
Run `npx skills add nwiizo/cargo-coupling --skill refactor -a codex`. Or copy the skill folder (.agents/skills/refactor in nwiizo/cargo-coupling) into .agents/skills/refactor in your project. Codex loads it when a task matches its description.
Can I use Refactor in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add nwiizo/cargo-coupling --skill refactor -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/refactor, .gemini/skills/refactor, .github/skills/refactor and .opencode/skills/refactor in your project.
What does Refactor need to run?
SKILL.md names no scripts, command-line tools or credentials: Refactor is instructions for the agent only.
Does Refactor access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Refactor safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Refactor use?
Refactor is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Refactor use?
About 511 tokens (SKILL.md is roughly 2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Refactor?
