Investment Analysis Workflow
When the user asks about stock performance, portfolio advice, or market analysis:
- Get live data via CLI — quotes, positions, K-line history, intraday
- Get news/catalysts via CLI — prefer Longbridge first; fall back to WebSearch only if insufficient
- Combine — price action + volume + catalyst → analysis + suggestion

Only fall back to WebSearch when Longbridge news is insufficient (e.g., breaking news not yet indexed, macro events unrelated to a specific symbol).

Related skills
The skills below are siblings in the longbridge/skills family. If they're installed, defer to them for the listed user intents — they're more specialised and produce better-formatted output. If they're not installed, this skill's own CLI workflow above can handle the same queries with less specialised formatting; the foundation skill remains usable standalone.
