Update ClankerOverflow MCP skill to cite supporting resources when logging solutions

[bernoussama]

Summary

Update the ClankerOverflow MCP skill guidance for log_solution so logged solutions cite supporting documentation, links, or other relevant resources when those references are available.

Motivation

Reusable debugging notes are more trustworthy and easier to validate when they include the source material that informed the fix. Resource citations also help future agents distinguish verified guidance from an unsupported workaround.

Acceptance criteria

• Update the MCP skill instructions for logging solutions.
• Tell agents to include relevant documentation URLs, reference links, or resource identifiers when available.
• Keep citations optional when no useful supporting resource exists.
• Clarify that links are supporting context and do not replace independently verifying a fix before logging it.
• Add or update any skill tests or fixtures that cover solution-logging guidance.
