codeindex-refactoring

A guided method for safely changing the structure of existing code, such as renaming symbols, extracting modules, splitting services, or moving code to another file.

In plain words
What is it for?
Use it to plan and apply code renames, extractions, splits, moves, and other structural changes, with previews and change checks.
Why use it?
It maps dependent code, execution paths, and references before edits, reducing the chance that a refactor breaks callers or tests.

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

codeindex-refactoring 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 2d 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.

Refactoring with CodeIndex

When to Use

  • "Rename this function safely"
  • "Extract this into a module"
  • "Split this service"
  • "Move this to a new file"
  • Any task involving renaming, extracting, splitting, or restructuring code

Workflow

1. codeindex_impact({target: "X", direction: "upstream"})  → Map all dependents
2. codeindex_query({query: "X"})                            → Find execution flows involving X
3. codeindex_context({name: "X"})                           → See all incoming/outgoing refs
4. Plan update order: interfaces → implementations → callers → tests

In Conductor worktrees, "Index is stale" can be an overlay/canonical-checkout mismatch. Use scripts/codeindex-health.sh; only run scripts/codeindex-health.sh --repair when it reports the shared base index is stale. Verify branch-local code with source files/diffs.

Checklists

Rename Symbol

- [ ] codeindex_rename({symbol_name: "oldName", new_name: "newName", dry_run: true}) — preview all edits
- [ ] Review graph edits (high confidence) and ast_search edits (review carefully)
- [ ] If satisfied: codeindex_rename({..., dry_run: false}) — apply edits
- [ ] codeindex_detect_changes() — verify only expected files changed
- [ ] Run tests for affected processes

Extract Module

- [ ] codeindex_context({name: target}) — see all incoming/outgoing refs
- [ ] codeindex_impact({target, direction: "upstream"}) — find all external callers
- [ ] Define new module interface
- [ ] Extract code, update imports
- [ ] codeindex_detect_changes() — verify affected scope
- [ ] Run tests for affected processes

Split Function/Service

- [ ] codeindex_context({name: target}) — understand all callees
- [ ] Group callees by responsibility
- [ ] codeindex_impact({target, direction: "upstream"}) — map callers to update
- [ ] Create new functions/services
- [ ] Update callers
- [ ] codeindex_detect_changes() — verify affected scope
- [ ] Run tests for affected processes

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.

codeindex-refactoring is a skill published in the GitHub repository GetKlai/klai (11 stars, last pushed 2d ago), licensed MIT. It adds 52 tokens to every session and 1,064 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
