+Scan my vault for actionable ideas — tools to build, essays to write, patterns to act on.
+
+1. Read all vault notes:
+   - @my-vault/The Junior Employee Mental Model.md
+   - @my-vault/Plan Mode.md
+   - @my-vault/CLAUDE.md Best Practices.md
+   - @my-vault/Context Window Management.md
+   - @my-vault/The Verification Loop.md
+   - @my-vault/Subagents.md
+   - @my-vault/Custom Commands.md
+   - @my-vault/Hooks.md
+   - @my-vault/The Death Spiral.md
+   - @my-vault/Voice-First Workflows.md
+
+2. Run these CLI commands to find high-value targets:
+   - `obsidian orphans` — neglected notes that deserve more attention
+   - `obsidian backlinks file="Custom Commands"` — most-connected action topics
+   - `obsidian backlinks file="The Junior Employee Mental Model"` — core mental model connections
+   - `obsidian tags counts` — dominant themes
+
+3. Generate actionable ideas across four categories:
+
+   **Tools to build**: Custom commands, hooks, or automations implied by the notes but not yet built
+   **Essays to write**: Tensions or patterns in the vault that deserve a full note of their own
+   **Connections to make**: People, communities, or resources that align with vault themes
+   **Experiments to run**: Small tests that would resolve open questions or tensions in the vault
+
+4. For each idea, output:
+   - **Idea**: [what to do]
+   - **Source**: [which notes imply this]
+   - **Why now**: [what makes this the right time]

 Surfaces hidden patterns — ideas your vault implies but you never explicitly stated. Finds conclusions from scattered premises, unnamed patterns, and unarticulated directions your thinking is heading.
