What it does
Refactor Simple is an agent skill from greenfield-inc/Pane. Read-only code quality analysis of the branch against the remote default branch for small to medium changes - classifies the diff, derives conventions from the target repo, and writes a refactor plan to ./tmp/. Usually run by the refactor orchestrator; use directly for a quick pre-PR check on 2-10 files.
Its SKILL.md is about 2.2k 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, covering Refactoring and Code quality. The repository describes itself as: Terminal-first, open-source AI agent manager for any CLI agent (agent agnostic), any OS (mac, windows, linux). The Open-Source Agentic Development Environment for running…
When your agent uses it
- Tasks that involve Refactoring
- Tasks that involve Code quality
Example prompts
- “/refactor-simple”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Classify Changes
- Learn the Repository's Conventions
- Analyze Files
- Generate Report
- Show Next Steps
What it can do on your machine
Read from SKILL.md and the folder at commit b08541d. 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
Refactor Simple loads about 2.2k tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 916 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 916 words (~2,161 tokens).
