Plugins

Automated unit-test generation: a /testgen command and generate_tests tool that scaffold, run, and fix tests until they pass (LLM + offline template generators; vitest/jest/mocha/node:test).

Structured test runner tool (test_run): auto-detect Vitest/Jest/pytest/node:test, run tests, parse failure summaries for the model.

Request Context Profiler for DeepSeek Harness — see what changed between model requests, and how cache reuse changed with it.
