Create comprehensive feature implementation plan with codebase analysis and research. Also wires bidirectional back/forward references between existing plans (the update-references workflow). Use when the user wants to plan a feature, turn a PRD into an implementation plan, "link two plans", "add a back/forward reference", "connect related plans", or invokes $prp-plan.

High
Do not use without reviewing
Security
1 high severity finding. You should review these findings carefully before considering using this skill.
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
The prompt explicitly requires including "actual (copy-pasted)" code snippets and pattern references from the codebase into the plan, which forces the agent to reproduce any plaintext secrets or credentials present in the repository verbatim, creating a high exfiltration risk.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
The required runtime workflow includes Phase 3 launching `web-researcher`, which fetches and summarizes external documentation from URLs on the public web into the agent’s LLM context (indirect prompt-injection risk via outsider-authored free text).
