bpe

bpe is a plugin for Claude Code from MasonEgger/bpe-claude-code-plugin. Its manifest loads nothing; the 13 skills, 3 agents it bundles cost 777 tokens per session together, scanned A, original, MIT.

A development workflow for turning project ideas into tested code through brainstorming, planning, execution, and review. TDD, or test-driven development, means writing tests to define expected behavior before implementing it.

In plain words
What is it for?
Use it to develop features from specifications, run multi-step coding tasks, validate results, and continue work across sessions.
Why use it?
It gives coding-agent sessions a shared process and keeps work connected across multiple sessions. A validation step helps check whether implemented work meets the plan.

Security

Grade A, and why

bpe 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 1mo 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 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.
