What investigation-memo does

The skill reads the investigation log and produces the first cut of the privileged memo. When a draft already exists, it shows what changed before rewriting anything. Every output carries the PRIVILEGED AND CONFIDENTIAL — ATTORNEY WORK PRODUCT marking.

Under the hood it loads the internal-investigation reference skill and runs Mode 4, draft or update memo. The memo structure, the credibility-assessment framework and the update rules all live in that reference skill, so it gets loaded before any substantive work starts.

On a first draft, the skill warns you if high-priority sources are still open on the checklist. Worth checking that list before the memo goes anywhere. The command takes a matter name as its argument: [matter name].

What it helps with

  • produce a first draft of the investigation memo from the log
  • refresh an existing memo after new data arrives
  • see a diff of changes before the rewrite
  • catch high-priority sources still open on the checklist
  • mark the document as attorney work product

Example prompts for the agent

  • /employment-legal:investigation-memo [matter name]
  • /employment-legal:investigation-memo [matter name] — update the existing memo
  • Draft the investigation memo for [matter name] from the investigation log
