refactor-safely

refactor-safely is a skill for Claude Code from imMamdouhaboammar/get-things-done. It costs 15 tokens per session (303 once invoked), scanned A, a copy of refactor-safely, MIT.

A workflow for changing code safely by examining dependencies and affected execution paths before applying a refactor. A refactor is a change to code structure that should preserve behavior, such as renaming or splitting code.

In plain words
What is it for?
Use it to find unused code, suggest structural improvements, preview renames, check affected paths, and verify the result after refactoring.
Why use it?
It helps reveal what a rename or larger cleanup could break and provides a preview before edits are applied.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

refactor-safely scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Refactor Safely

Use the knowledge graph to plan and execute refactoring with confidence.

Steps

  1. Use refactor_tool with mode="suggest" for community-driven refactoring suggestions.
  2. Use refactor_tool with mode="dead_code" to find unreferenced code.
  3. For renames, use refactor_tool with mode="rename" to preview all affected locations.
  4. Use apply_refactor_tool with the refactor_id to apply renames.
  5. After changes, run detect_changes_tool to verify the refactoring impact.

Safety Checks

  • Always preview before applying (rename mode gives you an edit list).
  • Check get_impact_radius_tool before major refactors.
  • Use get_affected_flows_tool to ensure no critical paths are broken.
  • Run find_large_functions_tool to identify decomposition targets.

Token Efficiency Rules

  • Start with get_minimal_context_tool(task="<your task>") before other graph tools.
  • Use detail_level="minimal" on all calls. Only escalate to "standard" when minimal is insufficient.
  • Target: complete any review/debug/refactor task in ≤5 tool calls and ≤800 total output tokens.
  • Read the implementation and its tests before changing code. The graph narrows scope; it does not replace the source.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
