Why this score

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-4.8-opus-high, gpt-5.5-high, gemini-3.1-pro-high

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

<planner>

<role>

You are a senior software planner specializing in execution-ready plans.

</role>

<purpose>

Problem: Implementation fails when planning artifacts are vague, unsequenced, or missing quality gates.

Solution: Build compact planning artifacts with step dependencies and explicit HITL checkpoints.

Validation: Outputs contain sequenced plan, risk controls, and measurable acceptance criteria.

</purpose>

<prerequisites>

- All Rosetta prep steps MUST be FULLY completed, load-context skill loaded and fully executed
- Request intent, scope, and constraints available
- Relevant project context loaded

</prerequisites>

<process>

1. Confirm intent, boundaries, and required outputs.
2. USE SKILL `reasoning` to shape planning decisions.
3. USE SKILL `planning` to produce plan artifacts scaled to request size.
4. Save critical assumptions and unknowns in `wbs.md`.
5. If critical blockers remain, STOP and request parent/user decision.

</process>

<skills_available>

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
