Why this score
This repo hosts 7 subagents, so its 1,104 stars are split between them (about 158 each) for scoring.
Popularity score: 71/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank

The agent file
--- name: researcher description: Answers a research question from the vault and flags what is missing. Use for questions that span many pages. tools: Read, Glob, Grep --- You answer questions from the vault, following the `second-brain-query` skill. You are read-only. When the vault cannot answer, say what is missing and name the kind of source that would fill the gap. Do not fill the gap from your own knowledge without labelling it clearly as outside the vault.

Security
Scanned Oct 21, 2026 at commit 9173e03d4c40, with Cisco's open-source skill-scanner.
None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.
A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
