Issue

Closes #23

Status: ✓ verified

Build, tests, and lint all pass locally.

Summary

Automated implementation by Ralph (rlmkit + MiniMax M2.5).
Review the changes carefully — this was generated by a local model.

Summary by CodeRabbit

New Features

  • Added five new guided coding exercises for practicing common refactoring tasks: fixing linting errors, renaming symbols, eliminating code duplication, adding type annotations, and updating deprecated APIs. Each exercise includes automated verification and evaluation criteria.

Walkthrough

Five new bootstrap YAML case files introduce standardized coding tasks: linting error fixes, symbol renaming, code deduplication extraction, TypeScript type annotations, and deprecated API updates. Each specifies task metadata, target file templates with initial content, and evaluation rubrics using command-based validators (linter, grep, type-checker, tests) to verify task completion.

Five new YAML task definitions for common refactoring/maintenance workflows. Each includes metadata (id, title, difficulty, language), a file template with seeding content, and a rubric with evaluators (linting, search, type-checking, or test commands) to validate completion against pass thresholds.

🧹 Nitpick comments (1)
cases/bootstrap/boot-002-rename-symbol.yaml (1)

28-36: Template code uses new on a plain function, which is misleading.

Line 34 calls new ${OLD_NAME}() on a function that simply returns x * 2. Using new on a non-constructor function silently discards the return value and yields an empty object. For a rename exercise template, a plain function call (const result = ${OLD_NAME}(5)) would be more representative and less confusing to the agent.

Suggested template fix
       function ${OLD_NAME}(x) {
         return x * 2;
       }

-      const ${OLD_NAME}_instance = new ${OLD_NAME}();
+      const ${OLD_NAME}_result = ${OLD_NAME}(5);

       module.exports = { ${OLD_NAME} };

⚠️ Potential issue | 🟠 Major

Missing evaluator to verify the old symbol is removed.

The rubric only checks that ${NEW_NAME} exists but never verifies that ${OLD_NAME} is absent. An agent could pass this criterion by simply adding the new name without removing the old one. The sibling cases (boot-003, boot-005) use a search + low passThreshold (0.1) to assert pattern absence — this case should do the same.

Proposed fix: add an evaluator for old-name absence

All functions and variables should have proper type annotations.

⚠️ Potential issue | 🟡 Minor

language should be typescript, not javascript.

The task is explicitly about adding TypeScript type annotations, the tags include typescript, and the evaluator runs a type-checker. The metadata field should match.
