# Plan Only: Anthropic-Core `as any` Type Safety Improvement

## IMPORTANT
- **DO NOT execute any code changes. Produce a detailed plan ONLY.**
- Output your plan to `docs/plans/as-any-cleanup.md` in the repo.
- For each of the 94 `as any`, classify as: (FIXABLE with concrete type fix), (JUSTIFIED — explain why), or (NEEDS_UPSTREAM — requires CCB upstream context)

## Goal
Eliminate all fixable `as any` casts in Anthropic-original decompiled code, improving type safety and reducing technical debt. These are all decompilation artifacts — the original Anthropic TypeScript had proper types that were lost in decompilation.

## Scope
94 `as any` across ~60 files. EXCLUDED areas: API providers (openai/grok/gemini — JSON parsing), community commands (acp/autofix-pr/share/issue), generated types, test files, .d.ts stubs.

## Categories for Analysis

For each occurrence, classify and recommend:

A. **Zod schemas** (2,5,6,92): `SomeSchema() as any` — schema type inference lost
B. **Message/attachment access** (7,29-31,40-41,56-58,67-68,70,77,88-89): accessing sub-properties not in SDKMessage type
C. **globalThis/global MACRO** (1,13-14,36-37,78,91): dev-mode constants injected at build time
D. **ComputerUse dynamic modules** (42-53): optional native module feature detection
E. **ConsoleOAuthFlow config** (19-25): settings update type mismatches
F. **Theme/permission/config** (4,72-74,75-76,80-81): style/permission type extensions
G. **CLI key handlers** (9-12): non-standard KeyboardEvent properties
H. **Performance polyfill** (34-37): Bun lacks browser performance API
I. **Dynamic function calls** (27-28,59): execaSync, openai client calls, dynamic imports
J. **Misc runtime access** (3,8,15-18,26,32-33,38-39,54-55,60-66,69,71,79,82-87,90,93-94)

## Verification
After plan is complete, verify by running:
```bash
export PATH="$HOME/.bun/bin:$PATH"
bun run typecheck  # should still have 20 errors (community code, unchanged)
```
