What is feature-driven-flow?

A plugin that organizes complex feature work into seven phases, from defining the task through reporting the result.

Guiding non-trivial feature development with defined steps for scope, exploration, clarification, design, implementation, verification, and summary.

It gives development work a consistent process for exploring a codebase, resolving unclear requirements, choosing a design, implementing changes, and checking the outcome.

Security

Grade A, and why

feature-driven-flow 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 yesterday.

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.
