 - `konductor update --cli` retries its smoke test of the downloaded binary when exec fails with
   "Text file busy" (ETXTBSY), instead of failing the update.
+- `k-architect` and `k-developer` no longer tell agents to use `aws___call_aws`, a tool the AWS MCP server has removed. Both now point at `aws___run_script`, which runs sandboxed Python with AWS API access.
+- `find-aws-skills`' failure-handling fallback no longer references `aws___suggest_aws_commands`, which the AWS MCP server does not expose. It now offers direct AWS API calls via `aws___run_script` (sandboxed Python).
+- `aws-service-validator` calls `aws___get_regional_availability` with `resource_type` (required), `regions`, and `filters` (required for more than one region), instead of a bare service-and-region call.
