The Amnesia Rule

The Rule

Write as if a future version of you — one month out, context gone — needs to understand what you wrote. If they can’t, rewrite it.

Why It Exists

Documentation rot is invisible while it’s happening. Context compresses into shorthand; shorthand ages into noise. A breadcrumb that says “continued from last time” is worthless to anyone who wasn’t there — including you, after compaction. The cost of brevity-without-context falls on whoever reads next, and that reader is almost always future-you.

The Amnesia Rule makes the cost legible at write time. Before you close a doc or commit a note, ask once: if I had amnesia and it was a month from now, would I understand what I wrote? That question has a clear yes or no.

What It Changes In Practice

• WORK_NOTES entries carry their own context — no references to “the thing from earlier” without naming the thing
• GROWTH log entries are written for re-reading, not just first-pass recording
• Skill docs and principle docs carry their own purpose in the first paragraph (the High School Rule and the Amnesia Rule together close the same gap from different angles)
• “Next steps” sections name the actual next step, not a pointer to a conversation that no longer exists in context

Where It’s Written

Household naming and documentation standards (hearthwell-naming-and-documentation-standards.md), the High School Rule (which enforces the same accessibility demand at the paragraph level), and operationally in the WORK_NOTES and GROWTH log formats every agent uses daily.
