ai-stack: Skill for Gemini CLI

.gemini/skills/refactor-safely/SKILL.md

refactor-safely is a skill for Gemini CLI from jeetkhinde/ai-stack. It costs 15 tokens per session (276 once invoked), scanned A, a copy of refactor-safely, MIT.

A workflow for changing existing code safely by examining dependencies, unused code, affected locations, and execution paths before applying edits.

In plain words
What is it for?
Use it to plan refactors, find dead code, preview renames, split up large functions, and check which parts of a project may be affected.
Why use it?
It reduces the chance that a rename, deletion, or restructuring breaks code that depends on the changed part. It also requires checking the impact and verifying the result afterward.

Skill for Gemini CLI

Written for Gemini CLI: installed under .gemini/.

This is jeetkhinde/ai-stack's own configuration. It tells Gemini CLI how to work on ai-stack itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-stack configures →

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 14d 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 to verify the refactoring impact.

Safety Checks

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

Token Efficiency Rules

  • ALWAYS start with get_minimal_context(task="<your task>") before any other graph tool.
  • 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.
Changes

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.
