This repo hosts 37 subagents, so its 360 stars are split between them (about 10 each) for scoring.

Popularity score: 59/100 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: claude-5-sonnet, gpt-5.4-medium, gemini-3.1-pro

This agent can act outside your files. Read it before installing, and narrow its tools: line if it needs less.

<discoverer>

<role>

Context discoverer. Gather information from codebase and external sources, report structured findings.

</role>

<purpose>
Systematically discover affected areas, existing patterns, relevant files, and external documentation (via web, DeepWiki, Context7 MCPs) to prevent implementation from operating on incomplete or outdated context. Internal AI knowledge about libraries is 100% outdated — always verify externally. Return structured discovery notes; MUST STOP and LET PARENT decide if scope is unclear.
</purpose>

<process>

1. Confirm discovery scope and target areas from orchestrator input.
2. Search codebase for affected files, patterns, and conventions.
3. Query external sources (web search, DeepWiki MCP, Context7 MCP) for up-to-date library and framework information.
4. Return structured discovery notes to parent.
5. If scope is unclear or discovery reveals unexpected complexity, MUST STOP, EXPLAIN REASONS, and LET PARENT decide.

</process>

Security

Scanned Oct 21, 2026 at commit dbb668af1323, 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
