missing required parameter '{key}'

Error message

missing required parameter '{key}'

What it means

Generic required-argument guard in the tiny.place agent-tool helpers: req_str found `key` missing, absent, or whitespace-only in the tool args (opt_str returns None for all three). Whichever parameter name appears in {key} is the one the calling tool requires as a non-empty string.

Solutions

1. Provide the named parameter as a non-empty string
2. Trim whitespace; an all-whitespace value is treated as missing
