What is research-plan-implement?

A coordinated workflow for researching a codebase, agreeing on a design, planning the work, implementing it, testing changes, and reviewing the result.

Use it for feature work that needs codebase research, design alignment, detailed plans, phase-by-phase implementation, verification, and review.

It keeps related development steps and their context together, so an agent is less likely to lose important decisions during a long task.

Security

Grade A, and why

research-plan-implement 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 2d 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.
