After the harness move from tools/marmot-interop/ to cli/tests/, three doc locations were still describing the old layout: - cli/DEVELOPMENT.md § Testing — the "round-trip" row pointed at a non-existent `cli/src/test/resources/scripts/`, and the "interop with other clients" row claimed it was out of scope. Both now name `cli/tests/marmot/` and `cli/tests/dm/` with what each covers, and the interop-script template points at the concrete test files rather than re-inventing a smaller example. - cli/README.md — the "For an interop-test script template" pointer now links to `cli/tests/README.md` alongside the DEVELOPMENT.md section. - .claude/skills/amy-expert/SKILL.md — the "Where things live" tree omitted the new `tests/` subtree entirely. Added it with a one-line description per suite. Also extended the wire-up checklist with a step 7: add a harness case when a new verb changes observable wire behaviour. No content changes elsewhere; just path corrections.
