adopting-prds

adopting-prds is a skill for Claude Code from ihistand/claude-plugins. It costs 78 tokens per session (11,313 once invoked), scanned A, original, no licence file.

A workflow for creating a product requirements document (PRD) from an existing codebase. A PRD is a plain-language record of what a product or feature should do; this workflow compares that record with the code and adds characterization tests, which capture current behaviour.

In plain words
What is it for?
It helps adopt a repository or one area of it into a living PRD, confirm intended behaviour, and close the work with tests.
Why use it?
It helps teams understand and document an existing system before changing it, rather than relying on guesswork.

Skill for Claude Code

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 A, and why

adopting-prds scanned grade A 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 today.

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.

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.
