What is codexspec-market marketplace?

A requirements-first software development toolkit for Claude Code, an AI coding assistant. It provides commands for recording requirements, writing specifications, planning work, breaking it into tasks, reviewing code, and managing configuration.

Use it to clarify requirements, generate specifications and plans, create implementation tasks, review work, and manage project settings.

It gives a project a structured path from an idea to implementation, so important decisions are not left only in chat or scattered across files.

Security

Grade A, and why

codexspec-market marketplace 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 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.

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.

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.
