bullpen

bullpen is a plugin for Claude Code from ccplugins/awesome-claude-code-plugins. Its manifest loads nothing; the 10 skills it bundles cost 1,738 tokens per session together, scanned A, original, Apache-2.0.

A bundle of coding guidelines for an AI agent, covering design decisions, verification, security checks, and finishing work to a senior-engineer standard.

In plain words
What is it for?
It helps an AI coding agent make decisions, test completed work, look for security problems, and improve code quality.
Why use it?
It gives the agent several focused habits for questioning weak plans, checking results, and reviewing its own code.

Security

Grade A, and why

bullpen scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it installs

The manifest is a name and a version. 10 skills travel with it, and installing the plugin installs all of them — 1,738 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
