openclaw - 💡(How to fix) Fix Dead Code Audit: 358 isolated production functions (static call graph analysis) [1 comments, 1 participants]

Dead Code Audit: 358 Isolated Production Functions

Static analysis of the codebase (via cqs call graph extraction) found 358 functions in production code that have:

• Zero callers (no other indexed function calls them)
• Zero callees (they don't call any other indexed function)

These are across 245 files. Test files, constructors, render methods, and main/entry points were excluded.

Categories

Many of these are likely:

1. Framework callbacks (Android lifecycle, macOS delegates) — called by the OS, not by code
2. Dependency injection setters (setXxxForTest) — called in test setup, not production
3. Exported utilities — called by consumers, not within this repo
4. Genuinely dead code — can be safely deleted

Prompt for cleanup

For each file listed below, check whether the flagged functions are:

• Framework callbacks: Keep, but add a comment like // Called by Android OS so future audits skip them
• Test injection points: Keep if tests use them; consider making them test-only exports
• Dead code: Delete and verify tests still pass

Methodology

Analysis performed with cqs v1.9.0 using BGE-large-en-v1.5 embeddings and tree-sitter call graph extraction across 51 supported languages. The call graph captures static function calls from tree-sitter AST analysis. Dynamic dispatch, framework callbacks, and cross-repo consumers are not captured — hence the false positive categories above.

Agent-ready prompt

For each file in the list above, read the file and classify each flagged function:

1. If it's a framework callback (Android lifecycle, macOS NSView delegate, 
   event handler interface method) — add a brief comment above it:
   `// Framework callback — called by OS/runtime, not by application code`

2. If it's a test injection setter (setXxxForTest, xxxMock, resetXxxForTests) — 
   check if any .test. file actually imports and calls it. If yes, keep it.
   If no test imports it, delete it.

3. If it's a Solid.js signal accessor (getter/setter pair with same name in 
   tui.ts or ui/ files) — these are reactive state. Keep them but skip future 
   dead code audits on signal accessors.

4. If it's none of the above and nothing imports it — delete it. Run the test 
   suite after each file to verify nothing breaks.

Work file by file. Commit after each file with message: 
"chore: remove dead code in <filename> (N functions)"

Start with the files that have the most isolated functions — they're most 
likely to contain genuinely dead code rather than framework callbacks.
