From 41c91db755bf67c52a8370ef52e33206d5cc55e1 Mon Sep 17 00:00:00 2001 From: nihalnihalani <24360630+nihalnihalani@users.noreply.github.com> Date: Tue, 14 Jul 2026 22:04:25 +0530 Subject: [PATCH 1/5] =?UTF-8?q?feat(sdk):=20rocketride.evals=20=E2=80=94?= =?UTF-8?q?=20golden-dataset=20evaluation=20engine=20for=20.pipe=20files?= =?UTF-8?q?=20(#1578)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New evals package: strict-JSON eval specs (.eval.json, versioned in git next to the pipeline they test), a deterministic assertion engine (contains/not_contains, regex, equals, min/max_length, json_path with dot-paths into structured output, latency_max_ms), and LLM-as-judge where the judge is itself a .pipe run on the same engine — no new LLM provider dependencies; the default judge template ships inside the wheel (rocketride/evals/templates/judge-default.pipe) and any judge pipeline can be substituted per spec or per case. - spec.py validates eagerly with file/case/assertion context (unique case names, known types, per-type required and unknown-key checks, min_score range) and resolves pipeline paths relative to the spec. - runner.py orchestrates use() → per-case chat() → guaranteed teardown in finally; judge pipelines run through the same client with per-path token caching; sync assertion evaluation runs on a worker thread bridged back to the loop via run_coroutine_threadsafe. - judge.py hardens the composed prompt against instructions embedded in the evaluated output and parses verdicts robustly (direct JSON, fenced, first balanced object); malformed verdicts fail the assertion with the raw text — never crash the run. - reporters.py renders human, single-document JSON, and JUnit XML (testsuite per spec, testcase per case, times in seconds). 158 unit tests across spec/assertions/judge/reporters/runner.

<24360630+nihalnihalani@users.noreply.github.com> Date: Tue, 14 Jul 2026 22:04:44 +0530 Subject: [PATCH 2/5] feat(cli): add 'rocketride eval' subcommand (#1578) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit rocketride eval [--case SUBSTR] [--fail-fast] [--json] [--junit PATH] — runs golden-dataset eval specs against the connected engine with the same connection flags/env fallbacks as the sibling subcommands. All specs are validated before connecting (any spec parse/validation error exits 2 before any network I/O); per-spec run failures are isolated so remaining specs still execute. --json prints a single machine-readable document; --junit writes standard JUnit XML for CI while keeping human output. Exit codes: 0 all cases pass; 1 any case fails; 2 usage/spec/connection error or no case produced a result. 31 CLI tests drive the full command against a fake client — no server required.
