- [x] **Fix**: Remove `Record<string, unknown>`/`as` usage in Claude agent files:
- `packages/server/src/server/agent/providers/claude-agent.test.ts:99`, `packages/server/src/server/agent/providers/claude-agent.test.ts:109`, `packages/server/src/server/agent/providers/claude-agent.test.ts:110`, `packages/server/src/server/agent/providers/claude-agent.test.ts:456`, `packages/server/src/server/agent/providers/claude-agent.test.ts:463`, `packages/server/src/server/agent/providers/claude-agent.test.ts:1279`
- `packages/server/src/server/agent/providers/claude-agent.ts:159`, `packages/server/src/server/agent/providers/claude-agent.ts:164`, `packages/server/src/server/agent/providers/claude-agent.ts:784`, `packages/server/src/server/agent/providers/claude-agent.ts:785`, `packages/server/src/server/agent/providers/claude-agent.ts:874`, `packages/server/src/server/agent/providers/claude-agent.ts:1120`, `packages/server/src/server/agent/providers/claude-agent.ts:1138`, `packages/server/src/server/agent/providers/claude-agent.ts:1162`, `packages/server/src/server/agent/providers/claude-agent.ts:1163`, `packages/server/src/server/agent/providers/claude-agent.ts:1249`, `packages/server/src/server/agent/providers/claude-agent.ts:1343`, `packages/server/src/server/agent/providers/claude-agent.ts:1347`, `packages/server/src/server/agent/providers/claude-agent.ts:1350`, `packages/server/src/server/agent/providers/claude-agent.ts:1364`, `packages/server/src/server/agent/providers/claude-agent.ts:1375`, `packages/server/src/server/agent/providers/claude-agent.ts:1392`
- **Done (2025-12-25 11:12)**: WHAT: replaced casted command/output handling with key-value type guards in `packages/server/src/server/agent/providers/claude-agent.test.ts:99`, `packages/server/src/server/agent/providers/claude-agent.test.ts:467`, `packages/server/src/server/agent/providers/claude-agent.test.ts:1157` and normalized Claude event/input parsing without casts in `packages/server/src/server/agent/providers/claude-agent.ts:112`, `packages/server/src/server/agent/providers/claude-agent.ts:1355`, `packages/server/src/server/agent/providers/claude-agent.ts:1463`, `packages/server/src/server/agent/providers/claude-agent.ts:1651`. RESULT: Claude agent/provider tests no longer use `Record<string, unknown>` or `as` assertions while preserving tool input/output and history parsing. EVIDENCE: `rg -n "Record<string, unknown>|\\bas\\b" packages/server/src/server/agent/providers/claude-agent.ts packages/server/src/server/agent/providers/claude-agent.test.ts` (no matches).
- [x] **SKIP**: Codex SDK agent files (`codex-agent.ts`, `codex-agent.test.ts`) - DEPRECATED.
- `codex-agent.ts` is the old SDK provider, replaced by `codex-mcp-agent.ts`
