Instruct Compact

Synthesize the current session into a directive block the user copy-pastes into /compact <paste>. The block tells the built-in summarizer what to preserve verbatim, what to compress, and what to drop — so intentional compaction keeps signal and sheds noise.

Output: a fenced block only, printed to terminal. No file written. Target: 250-400 tokens. Speed: 3-5s.

Distinct from /save-context (durable CONTEXT-*-llm.md for resuming later). This is ephemeral steering for compaction now.

When to Use

• User is about to run /compact and wants to control what survives
• Long session nearing auto-compaction; user wants to front-load survival priorities
• Triggers: "instruct compact", "compaction instructions", "steer compact", "prepare compaction"

Instructions

1. Read the conversation (last 15-20 messages) — no shell needed unless confirming a file path.
2. Synthesize the 7 sections (below). Write directives to the summarizer, not the content itself — e.g. "Preserve exact path x/y.md", not a copy of the file. Embed a literal only when losing it is expensive (exact paths, the one key decision).
3. Print the block using the template. Nothing else after it except one line: Copy the block above into /compact.
