prp-ralph

prp-ralph is a command for coding agents from NanoBoom/nano-claude-code-plugins. It costs 13 tokens per session (3,687 once invoked), scanned B, original, no licence file.

A command that repeatedly follows a PRP plan, meaning a written implementation plan, until its required checks pass.

In plain words
What is it for?
Running an implementation plan through repeated coding and validation cycles.
Why use it?
It reduces the need to manually restart the work after each incomplete attempt or failed validation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

prp-ralph scanned grade B with 1 finding 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 4d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

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.
