          "D8 \u2014 Journey Stage: UPGRADE\n\nFriction point: v1 Client.evaluate() removed with no migration path\n\nProject/branch: EvalKit SDK 2.0.0b1 / main\n\nELI10: When developers upgrade from v1 to v2, `Client.evaluate()` is gone and replaced by `Client.run()`. No deprecation warning, no compatibility alias, no migration guide, no codemod. Any v1 user who does `pip install --upgrade evalkit` gets a silent AttributeError on their next eval run \u2014 probably in production. This is called an 'upgrade cliff' and it's one of the most reliable ways to destroy developer trust in an SDK.\n\nStakes if we pick wrong: Every v1 user who upgrades without reading the full changelog (most of them) will have their production evals silently fail with `AttributeError: 'Client' object has no attribute 'evaluate'`. They will immediately downgrade, stop upgrading, or switch SDKs.\n\nRecommendation: A \u2014 add a deprecation shim. `Client.evaluate()` calls `Client.run()` and logs a DeprecationWarning. Costs almost nothing, eliminates the upgrade cliff.\n\nCompleteness: A=10/10, B=8/10, C=3/10.\n\nPros / cons:\nA) Fix: add Client.evaluate() compatibility alias that calls Client.run() with a DeprecationWarning (recommended)\n  \u2714 Zero-risk upgrade path for v1 users; their code works immediately, the warning tells them to migrate\n  \u2714 Three lines of code in client.py; changelog entry takes 2 sentences; migration guide takes one paragraph\n  \u274c Keeps v1 API surface in v2 codebase; must be removed in v3 (planned obsolescence, not technical debt)\nB) Add a migration guide only (no alias)\n  \u2714 Documents the change clearly; developers who read it can migrate in minutes\n  \u274c Requires every v1 user to read the migration guide before upgrading; most won't; they still hit AttributeError\nC) Retain hard break with no migration path per the plan\n  \u2714 Cleanest v2 codebase; no legacy surface area\n  \u274c Every v1 user who upgrades will get an AttributeError in their production code; this is the plan the DX review was asked to improve\n\nNet: A three-line compatibility shim eliminates a production-breaking upgrade cliff for all v1 users. The cost of shipping it is near zero. The cost of not shipping it is measured in lost users and support tickets.\n\n<gstack-qid:plan-devex-review-fp-upgrade>": "A) Fix: add Client.evaluate() compat alias + DeprecationWarning (Recommended)"

  "report": "# DX Review: EvalKit SDK 2.0.0b1 Beta Release Polish\n\n## Context\n\nEvalKit is a Python SDK for ML engineers evaluating LLM responses. This review\napplies **DX POLISH** mode to the existing release scope \u2014 no new surfaces, no new\nhosted services, no new language bindings. The goal is to make every documented\ntouchpoint bulletproof before the beta ships.\n\nFive developer-facing contracts in the current plan are actively harmful to the ML\nengineer persona: a broken quickstart reference, a silent 5-minute CI block, a\nzero-information auth error, reversed argument order between the two main functions,\nand a production-breaking v1\u2192v2 upgrade cliff. All five were confirmed by tracing\nthe actual getting-started path through README.md, docs/current-contracts.md,\ndocs/api.md, and docs/package-contents.txt.\n\n---\n\n## Developer Persona Card\n\n```\nTARGET DEVELOPER PERSONA\n========================\nWho:       ML engineer \u2014 writes Python daily, uses a terminal\nContext:   Evaluating whether EvalKit can replace manual LLM output review\n           before integrating it into production CI\nTolerance: ~15 minutes before abandoning; will copy-paste README commands verbatim\nExpects:   pip install + one command = working eval result; no guesswork,\n           no waiting without feedback, no broken links\n```\n\n---\n\n## Developer Empathy Narrative\n\nI'm an ML engineer. My team evaluates LLM outputs manually today. EvalKit promises\nto automate this. I have 15 minutes before my next meeting.\n\nI open the README. The first heading is `# EvalKit SDK`. The pitch is clear. I scroll\nto Getting Started.\n\n`pip install evalkit==2.0.0b1` \u2014 fine, I run it. Sets EVALKIT_API_KEY \u2014 I go to my\ndashboard, copy my key, export it.\n\nThen: *\"follow the quickstart's command: `python examples/first_eval.py`\"*\n\nI run it. `python: can't open file 'examples/first_eval.py': [Errno 2] No such file or\ndirectory`\n\nI didn't expect that. I look at the README again. Ah \u2014 there's another command further\ndown: `python -m evalkit.demo`. I run that instead.\n\nNothing happens. The cursor blinks. No output. No spinner. No \"Connecting to CI...\"\nmessage. I wait. I wait more. After 4 minutes I check if my terminal is frozen. After\n5 minutes, results print. It worked. But I have no idea what just happened or why it\ntook 5 minutes \u2014 or whether what I see is the right output.\n\nTotal time: 7 minutes including the wrong path. I'm over my TTHW target by 3.5x. And I\nstill don't know if this will be fast in CI or always take 5 minutes.\n\n---\n\n## Competitive DX Benchmark\n\n```\nTool            | TTHW   | Notable DX Choice                  | Source\nPeer SDK A      | 2 min  | No mandatory remote check at T0    | docs/benchmarks.md\nPeer SDK C      | 3 min  | Offline mode available             | docs/benchmarks.md\nPeer SDK B      | 4 min  | Requires account setup             | docs/benchmarks.md\nEvalKit 2.0.0b1 | 6 min  | Mandatory 5-min CI block on T0     | docs/current-contracts.md\nEvalKit target  | <2 min | Agreed per benchmarks.md           | docs/benchmarks.md\n```\n\nAfter fixes: EvalKit lands at **Champion tier (<2 min)** \u2014 matching the agreed target\nand beating all three peer SDKs.\n\n---\n\n## Magical Moment Specification\n\n**Delivery vehicle:** `python -m evalkit.demo` (copy-paste demo command)\n\n**Required implementation:**\n- Add `--skip-ci` flag (or `EVALKIT_SKIP_CI=1` env var) to `evalkit/demo.py`\n- Add progress output during CI wait: `\"Waiting for CI check... (up to 5 min)\"`\n  with a spinner so developer knows the process is alive\n- Demo must complete in under 60 seconds with skip flag enabled\n- README must show expected demo output (sample per-example scores + overall score)\n  so developer can immediately confirm success\n\n**Success state:**\n```\n$ python -m evalkit.demo --skip-ci\nEvaluating 10 sample responses...\n  Response 1: 0.82\n  Response 2: 0.76\n  ...\n  Response 10: 0.91\n\nOverall score: 0.84\nDemo complete. Run `evalkit --help` to evaluate your own data.\n```\n\n---\n\n## Developer Journey Map\n\n```\nSTAGE           | DEVELOPER DOES              | FRICTION POINTS        | STATUS\n----------------|-----------------------------|-----------------------|--------\n1.

Run with Claude Code or Codex; checkbox as you ship.\n\n- [ ] **T1 (P1, human: ~2h / CC: ~15min)** \u2014 Demo module \u2014 Add `--skip-ci` flag (or `EVALKIT_SKIP_CI=1` env var) to `python -m evalkit.demo` for offline first-run path\n  - Surfaced by: Pass 1 (Getting Started) \u2014 mandatory 5-min CI block makes TTHW 6 min vs 2-min target (docs/benchmarks.md)\n  - Files: `evalkit/demo.py`, `evalkit/client.py`\n  - Verify: `python -m evalkit.demo --skip-ci` completes in <60 seconds with real per-example scores from sample_responses.json\n\n- [ ] **T2 (P1, human: ~30min / CC: ~5min)** \u2014 README \u2014 Replace `python examples/first_eval.py` with `python -m evalkit.demo` as the primary getting-started command\n  - Surfaced by: Pass 1 (Getting Started) \u2014 `examples/first_eval.py` is absent from published package (docs/package-contents.txt)\n  - Files: `README.md`\n  - Verify: Follow README verbatim from a clean install; confirm no FileNotFoundError\n\n- [ ] **T3 (P1, human: ~1h / CC: ~10min)** \u2014 Demo module \u2014 Add progress indicator during CI check\n  - Surfaced by: Pass 1 (Getting Started) \u2014 5-min silent wait with no output looks like a frozen process\n  - Files: `evalkit/demo.py`\n  - Verify: Without skip flag, terminal shows `\"Waiting for CI check... (up to 5 min)\"` or equivalent spinner\n\n- [ ] **T4 (P1, human: ~30min / CC: ~5min)** \u2014 Error handling \u2014 Fix `AuthError` message to include cause and actionable fix\n  - Surfaced by: Pass 3 (Error Messages) \u2014 `AuthError(\"request failed\")` violates current-contracts.md's own error standard\n  - Files: `evalkit/client.py`\n  - Verify: With invalid `EVALKIT_API_KEY`, error message names the env var and directs to key regeneration\n\n- [ ] **T5 (P1, human: ~2h / CC: ~15min)** \u2014 API design \u2014 Standardize `run_batch` argument order to `(dataset, evaluator)` to match `run_eval`\n  - Surfaced by: Pass 2 (API/CLI/SDK) \u2014 reversed positional order causes silent wrong results when using both functions\n  - Files: `evalkit/client.py`, `docs/api.md`\n  - Verify: `run_eval(ds, ev)` and `run_batch(ds, ev)` both evaluate `ds` using `ev`; changelog notes the change\n\n- [ ] **T6 (P1, human: ~1h / CC: ~10min)** \u2014 Client \u2014 Add `Client.evaluate()` compatibility alias calling `Client.run()` with `DeprecationWarning`\n  - Surfaced by: Pass 5 (Upgrade Path) \u2014 v1 users get `AttributeError` on upgrade with no migration path\n  - Files: `evalkit/client.py`\n  - Verify: v1 code using `Client.evaluate()` works with a `DeprecationWarning` instead of `AttributeError`\n\n- [ ] **T7 (P2, human: ~1h / CC: ~10min)** \u2014 Docs \u2014 Add v1\u2192v2 migration guide to `docs/api.md`\n  - Surfaced by: Pass 5 (Upgrade Path) \u2014 no migration guide for `Client.evaluate()` \u2192 `Client.run()` rename\n  - Files: `docs/api.md`\n  - Verify: A developer upgrading from v1 finds clear instructions in docs/api.md\n\n- [ ] **T8 (P2, human: ~30min / CC: ~5min)** \u2014 README \u2014 Add sample demo output under Getting Started\n  - Surfaced by: Pass 4 (Documentation) \u2014 demo output not documented; developer can't confirm success\n  - Files: `README.md`\n  - Verify: README shows expected output format with per-example scores and overall score\n\n---\n\n## Unresolved Decisions\n\nNone.\n\n---\n\n## GSTACK REVIEW REPORT\n\n| Review | Trigger | Why | Runs | Status | Findings |\n|--------|---------|-----|------|--------|----------|\n| CEO Review | `/plan-ceo-review` | Scope & strategy | 0 | \u2014 | \u2014 |\n| Outside Review | codex (disabled) | Independent 2nd opinion | 0 | disabled | \u2014 |\n| Eng Review | `/plan-eng-review` | Architecture & tests (required) | 0 | \u2014 | \u2014 |\n| Design Review | `/plan-design-review` | UI/UX gaps | 0 | \u2014 | \u2014 |\n| DX Review | `/plan-devex-review` | Developer experience gaps | 1 | issues_found | score: 4/10 \u2192 7/10, TTHW: 6 min \u2192 <2 min |\n\n**OUTSIDE COVERAGE:** codex disabled (user preference).
