swift-rename-symbol

swift-rename-symbol is a skill for Claude Code from drewalth/claude-xcindex. It costs 78 tokens per session (877 once invoked), scanned A, original, MIT.

A code refactoring tool for renaming a Swift or Objective-C symbol, such as a type, method, property, protocol, or enum case, across its actual uses.

In plain words
What is it for?
Use it when renaming a symbol in an Xcode project and you need its definition, references, overrides, and related protocol code updated precisely.
Why use it?
It avoids changing unrelated words in comments, text strings, or other code that happens to use the same name.

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

swift-rename-symbol 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

What this skill does

Performs an index-backed rename: every reference site for the symbol's USR is edited, and only those sites. Same-named tokens in comments, string literals, or unrelated modules are left alone.

The work is delegated to the swift-refactor-specialist subagent. The main session doesn't read 50 files — it gets a short summary back.

How to use

  1. Confirm with the user that this is an execution step, not a scoping step. If you're not sure, run swift-refactor-plan first and ask.
  2. Announce: "I'll dispatch the rename to the swift-refactor-specialist."
  3. Hand the subagent: old name, new name, project path (or index store path).
  4. Review the returned summary; spot-check 2–3 representative sites if the rename touched many files.

What the subagent does

The subagent has find_symbol, find_references, find_definition, find_overrides, find_conformances, blast_radius, Read, and Edit. It will:

  1. find_symbol(symbolName: "OldName") → resolve to a USR + definition site.
  2. Confirm the USR is the right kind/module. If multiple match, return to the main session and ask.
  3. find_references(symbolName: "OldName") → every occurrence.
  4. Edit each site precisely. The definition site is handled last and may need a different replacement (e.g. class header vs. body usage).
  5. Return: number of files touched, list of edited paths, anything skipped.

Edge cases the subagent flags

  • Overloads — multiple USRs for the same name. Surface the choice; don't guess.
  • @objc bridging — find_references flags .dynamic roles. Objective-C call sites outside the index are invisible; warn the user.
  • Extensions in other files — included by the index; check containedBy roles in the result so extension headers update with the type.
  • Protocol conformances and overrides — use find_overrides and find_conformances to avoid leaving a dangling subclass.
  • Test doubles / mocks — coveringTests from blast_radius should also update; the subagent reports any mock site it edits.

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.
