#3402: docs(discord): clarify search doesn't support OR/AND operators

## Summary Agents often mistakenly try to use boolean operators (OR/AND) in Discord search queries, expecting SQL-like or web-search behavior. Discord's search API matches queries literally as phrases. ## Changes Added a note to the Discord skill's search section clarifying this limitation and suggesting separate calls for multiple terms. ## AI-assisted - **Tool:** Claude - **Testing level:** Lightly tested (documentation-only change) - **Understanding:** Yes, this is a simple doc clarification based on observed agent behavior <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> This PR updates the Discord skill documentation (`skills/discord/SKILL.md`) by adding a note in the message search section clarifying that Discord search does not support boolean operators like `OR`/`AND` and that queries are matched literally; it recommends issuing separate searches for multiple terms. This fits into the repo’s skill docs as guidance to reduce common agent/user misuse of `searchMessages` queries. <h3>Confidence Score: 5/5</h3> - This PR is safe to merge with minimal risk. - Documentation-only change localized to the Discord skill docs; no code paths or tooling behavior are modified, and the added note is consistent with the described Discord search limitation. - No files require special attention <!-- greptile_other_comments_section --> **Context used:** - Context from `dashboard` - CLAUDE.md ([source](https://app.greptile.com/review/custom-context?memory=fd949e91-5c3a-4ab5-90a1-cbe184fd6ce8)) - Context from `dashboard` - AGENTS.md ([source](https://app.greptile.com/review/custom-context?memory=0d0c8278-ef8e-4d6c-ab21-f5527e322f13)) <!-- /greptile_comment -->
