This skill should be used when the user says "planning", "arness planning", "plan a feature", "start planning", "I want to build", "new feature", "plan something", "what should I build", "pick an issue", "plan a bug fix", "I have an idea", "spec and plan", "plan from scratch", "plan this", "feature planning", "bug planning", "plan this issue", "arn-planning", or wants to go from an idea, issue, or bug report through to a complete implementation plan ready for execution. Handles severity-aware scope routing across three ceremony tiers (swift, standard, thorough), routing between feature specs, bug specs, and quick implementations, and produces a reviewed plan ready for execution. Chains to arn-implementing at completion.

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 skill explicitly invokes "Skill: arn-code:arn-code-pick-issue" (browse mode) from Step 0/Step 1/G1 ("Pick from backlog") to load issue backlog items from the configured issue tracker (e.g., GitHub or Jira), and then uses the loaded issue content as planning input—this consumes untrusted, user-generated third‑party content that can materially influence decisions and tool chaining.
