Summary

Follow-up to #69 (same crash class, different args).

plugins/_code_execution/tools/code_execution_tool.py:60 — int(self.args.get("session", 0))
plugins/_code_execution/tools/input.py:13 — same
tools/notify_user.py:14 — int(self.args.get("timeout", 30))
plugins/_a0_connector/tools/code_execution_remote.py:155 — or 0 handles None but not strings
plugins/_a0_connector/tools/text_editor_remote.py:71-73 — truthy-guarded but not type-guarded int(self.args["line_from"])

A model passing "session": "0 " or "line_from": "10-20" raises ValueError, which is not converted to a repairable tool error and kills the monologue loop.

Suggested fix

Reuse computer_use_remote._coerce_int (or promote it to helpers/tool.py as Tool.get_int(name, default)) at all sites. Optionally add Tool.get_str for #69.
