> `<cai>` is the cai-codex command line that `$setup` wrote into your instructions (the cai-codex block in AGENTS.md). `<cai-root>` is what `<cai> --root` prints.  # Encapsulate Downcast Catalog #54 · Making Method Calls Simpler · risk **L** (local and mechanical) Addresses: caller-side casts Target: `$ARGUMENTS` ## Do this 1. Read the **Encapsulate Downcast** card in `<cai-root>/skills/refactor/references/cat-10-method-calls.md`. Its **Pre** and **Mechanics** sections are authoritative — this command does not restate them, so that there is one source of truth. 2. Apply the safety protocol yourself: pre-flight, step-by-step mechanics with a test after each step, full suite, commit. It is defined once in `<cai-root>/skills/refactor/SKILL.md` under "## Non-negotiable safety protocol"; it is not restated here. The heading is the anchor on purpose -- a line number here would be stale the next time anything above it is edited, in all 72 of these files at once. 3. Behaviour must not change. Do not modify tests except for a rename you name explicitly in the report. Do not start a second refactoring — report any follow-up the card indicates instead. If a precondition fails, stop and name the correct alternative refactoring rather than forcing this one.
