Hi @denis-samatov,

Thank you for this fix! Swallowing flag arguments (like --limit 3 or --type Fact) into bundleDir when no explicit path was provided was indeed a subtle and nasty CLI parsing bug. Your positional boundary separation in splitOptionalPath along with the comprehensive test coverage in cmd/okf/main_test.go solves this cleanly.

I have merged your contribution directly into our develop branch with full author attribution in commit a09e049 (along with your improvements in #15, #16, and #17).

A quick note for future contributions:
Starting today, we have updated our contribution guidelines to an Issue-First workflow on the develop branch (see CONTRIBUTING.md):

Please open an Issue first to discuss ideas or bug reports before submitting PRs.
Always base and target your PRs against develop (our default branch) rather than main (which is reserved for tagged production releases).
Please fill out the PR description template with context and verification details.
Thanks again for helping improve okf-agent-memory!
