Claude Code agents were passing --items as a single JSON array string (e.g. --items '["Step 1", "Step 2"]'), creating one malformed checklist item instead of individual items. This happened because buildToolGuidance() rendered array params as `--items <array>`, giving no indication that repeated flags are needed. - Extract formatParam() helper from buildToolGuidance() to reduce cognitive complexity and handle array-type params - Array params now render as `--item <string> (repeatable)` instead of `--items <array>` - Rename CLI flag from --items to --item (singular) to match convention - Rename tool manifest param from items → item to match the CLI flag - Add test coverage for array parameter rendering (required + optional) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
