One thing to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

What its author says it does

Copied from the file, not written here

Use when the user wants to rename, extract, split, move, or restructure code safely. Examples: "Rename this function", "Extract this into a module", "Refactor this class", "Move this to a separate file"

Refactoring with GitNexus

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

If "Index is stale" → run npx gitnexus analyze in terminal.

Checklists

Rename Symbol

- [ ] gitnexus_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: gitnexus_rename({..., dry_run: false}) — apply edits
- [ ] gitnexus_detect_changes() — verify only expected files changed
- [ ] Run tests for affected processes

Extract Module

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

Split Function/Service

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

Tools

gitnexus_rename — automated multi-file rename:

gitnexus_rename({symbol_name: "validateUser", new_name: "authenticateUser", dry_run: true})
→ 12 edits across 8 files
→ 10 graph edits (high confidence), 2 ast_search edits (review)
→ Changes: [{file_path, edits: [{line, old_text, new_text, confidence}]}]

gitnexus_impact — map all dependents first:

gitnexus_impact({target: "validateUser", direction: "upstream"})
→ d=1: loginHandler, apiMiddleware, testUtils
→ Affected Processes: LoginFlow, TokenRefresh

gitnexus_detect_changes — verify your changes after refactoring:

gitnexus_detect_changes({scope: "all"})
→ Changed: 8 files, 12 symbols
→ Affected processes: LoginFlow, TokenRefresh
→ Risk: MEDIUM

gitnexus_cypher — custom reference queries:

MATCH (caller)-[:CodeRelation {type: 'CALLS'}]->(f:Function {name: "validateUser"})
RETURN caller.name, caller.filePath ORDER BY caller.filePath

Risk Rules

Risk Factor	Mitigation
Many callers (>5)	Use gitnexus_rename for automated updates
Cross-area refs	Use detect_changes after to verify scope
String/dynamic refs	gitnexus_query to find them
External/public API	Version and deprecate properly

Example: Rename `validateUser` to `authenticateUser`

1. gitnexus_rename({symbol_name: "validateUser", new_name: "authenticateUser", dry_run: true})
   → 12 edits: 10 graph (safe), 2 ast_search (review)
   → Files: validator.ts, login.ts, middleware.ts, config.json...

2. Review ast_search edits (config.json: dynamic reference!)

3. gitnexus_rename({symbol_name: "validateUser", new_name: "authenticateUser", dry_run: false})
   → Applied 12 edits across 8 files

4. gitnexus_detect_changes({scope: "all"})
   → Affected: LoginFlow, TokenRefresh
   → Risk: MEDIUM — run tests for these flows
