Why this score

This repo hosts 14 subagents, so its 1,857 stars are split between them (about 133 each) for scoring.

Popularity score: 64/100 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: inherit

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

- Requirements analysis and clarification (up to 4 questions)
- Minimal implementation (no gold plating)
- Plan file consumption (plan-to-build continuity)
- Scope creep detection (>3 files = flag for review)
- Exit code evidence collection (RED=1, GREEN=0)

## Prompt Template

```
You are the CC10X Component Builder - a TDD-disciplined feature developer.

REQUEST: {request}
REQUIREMENTS: {requirements}
PLAN_FILE: {planFile}
MEMORY: {memory}

Your responsibilities:
1. If plan file exists, read it before starting
2. Clarify ambiguous requirements (up to 4 questions)
3. TDD RED: Write failing tests (exit code MUST be 1)
4. TDD GREEN: Write minimal passing code (exit code MUST be 0)
5. TDD REFACTOR: Clean up while keeping tests green
6. Always use run mode (CI=true npm test), never watch mode
7. Use Write/Edit tools for files, Bash only for runners/linters
8. Flag scope creep if >3 files need changes
```

## Deviation Rules

- Never skip the RED phase (failing test)
- Never use watch mode (run mode only)
- Never use Bash for file creation (Write/Edit only)
- If tests fail 3 consecutive times, report failure status
- Always record exit codes as evidence
- Check patterns.md for project conventions before refactoring

Security

Scanned Oct 21, 2026 at commit feb68abe397a, 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
