huytieu/COG-second-brainSubagent
Web research agent. Searches, fetches URLs, extracts facts and evidence. No synthesis — just structured findings.
Why this score
This repo hosts 20 subagents, so its 1,301 stars are split between them (about 65 each) for scoring.
Popularity score: 62/100 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
What it can use
- Every tool, because it sets no tools list (it inherits all of yours, including shell and MCP tools)
Model: flash
This agent can act outside your files. Read it before installing, and narrow its tools: line if it needs less.
The agent file
--- name: worker-researcher description: Web research agent. Searches, fetches URLs, extracts facts and evidence.

Security
Scanned Oct 22, 2026 at commit 36ac9d78d66e, 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
