◇ Could this help me?

Yes: Context7 and Plan Mode are immediately actionable. Context7 prevents outdated API usage (high value). Sequential Thinking MCP is worth trying for complex multi-step tasks. Research each add-on before installing, per the Instruction column.

Four Claude Code add-ons. Research each before installing, do NOT install until each has been reviewed and approved:
Context7 MCP: feeds current library docs on demand. It's in the official Claude Code plugin marketplace (/plugin -> search 'Context7'); still confirm what it is and that it's the official one before installing.
Sequential Thinking MCP: adds a reasoning/pause layer. Find its GitHub repo and research who publishes it and whether it's safe.
Superpowers MCP: forces Claude to back up work before claiming done. Same research-first flow via its GitHub repo.
Plan Mode: built-in, nothing to install (Shift+Tab until 'plan mode' shows).
For the three MCPs, present the findings for review and install ONLY after explicit approval.
