indexion-refactor

indexion-refactor is a skill for Claude Code from trkbt10/indexion-skills. It costs 48 tokens per session (3,558 once invoked), scanned A, original, Apache-2.0.

A code-refactoring workflow that finds duplication in code, shared packages, and design decisions. It also checks whether one clear source of truth is being maintained.

In plain words
What is it for?
Use it after adding abstractions, changing file formats, touching several files for one fix, extracting shared code, or cleaning up after a refactor.
Why use it?
It helps reveal repeated logic and unnecessary wrappers that can make a codebase harder to change consistently.

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

indexion-refactor 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 11d 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.

indexion refactor — Codebase Refactoring

Detect and eliminate duplication at three levels — textual, structural, and conceptual — using indexion's analysis commands, then verify SoT is enforced.

When to Use

  • After adding a new abstraction (type, module, API layer)
  • After introducing a new file format or I/O boundary
  • When a fix required touching 3+ files for the same reason
  • When a "guard" or "skip" was added to work around a structural problem
  • When opendir, ENOENT, or similar filesystem errors appear from unexpected paths
  • When extracting shared code across packages
  • When cleaning up after a refactor (removing trivial wrapper functions)
  • Periodic SoT health check on a codebase

Three Levels of Duplication

Level What it is Tool Example
Textual Copy-pasted code blocks, identical functions plan refactor is_whitespace copied across 5 modules
Structural Same logic structure with different names plan solid, plan unwrap cross-package extraction candidates, trivial wrappers
Conceptual Same domain concept implemented independently explore + manual analysis Three modules each deciding "is this file an archive?"

Textual duplication is easy to find and fix. Conceptual duplication is the hardest and most dangerous — it produces no copy-paste matches but means changing one concept requires updating every scattered implementation.

Workflow

Phase 1: Clear textual duplication (plan refactor)

Start with high-confidence matches and work down.

# Step 1: Find 90%+ duplicates (high confidence)
indexion plan refactor --threshold=0.9 \
  --include='*.mbt' --exclude='*_wbtest.mbt' \
  --exclude='*moon.pkg*' --exclude='*pkg.generated*' \
  cmd/indexion/

indexion plan refactor --threshold=0.9 \
  --include='*.mbt' --exclude='*_wbtest.mbt' \
  --exclude='*moon.pkg*' --exclude='*pkg.generated*' \
  src/
