The whole skill now loads on Antigravity, measured on 2026-10-29

The skill's load layout changed so that Antigravity's 24,000-byte load reaches Step 4 and every standing rail. The SKILL.md body is 21,047 bytes, down from 51,554.

Changed

• The steps and the standing rails move to references. The steps (Step 0 to Step 4, Memory & resume, Modes) move to references/steps.md, and Grants & denials and Always move to references/rails.md. Both are MANDATORY before Step 0 on every lane, and the References ledger lists 8 MANDATORY. The text moved byte for byte; nothing was reworded except location pointers.
• The Antigravity claim is validated, as measured. Measured 2026-10-29 with agy 1.4.8 (a self-run headless check, not third-party-audited): the whole skill loads, and a report-only load check reached Step 4 with every rail read. Claude Code's claim is unchanged; every other platform stays designed-for, unverified.

Security

• SECURITY.md now states what counts as a vulnerability for this repo.
