# Changelog

All notable changes to this project should be documented here.

## [0.2.0](https://github.com/tryingET/pi-evalset-lab/compare/v0.1.0...v0.2.0) (2026-02-17)


### Features

* **evalset:** add JSON to HTML report export helper ([802e7d2](https://github.com/tryingET/pi-evalset-lab/commit/802e7d2a13a44205e519e0f0c778788fd093340f))

## [Unreleased]

### Added

- Added `/evalset` MVP command with subcommands:
  - `init` to generate a starter fixed-task-set dataset
  - `run` to evaluate one variant against a dataset
  - `compare` to evaluate baseline vs candidate system prompts
- Added example files in `examples/`:
  - `fixed-task-set.json`
  - `fixed-task-set-v2.json`
  - `fixed-task-set-v3.json`
  - `evalset-compare-sample-embedded.html`
  - `evalset-compare-sample.png`
  - `system-baseline.txt`
  - `system-candidate.txt`
- Added report output support to `.evalset/reports/*.json` with per-case and aggregate metrics.
- Added run identity metadata to reports (`runId`, `datasetHash`, `casesHash`, `variantHash`).
- Reduced session message payload size by storing only lightweight report metadata instead of full report bodies.
- Added `scripts/export-evalset-report-html.mjs` and `npm run evalset:export-html` for repeatable JSON -> static HTML report exports.

### Changed

- Clarified `/evalset` invocation docs: use `pi -p` (or `pi -e ... -p`) for non-interactive runs; `/evalset` is not a standalone shell binary.
- Added the same non-interactive invocation note to `/evalset help` output.
- Declared publish-time runtime artifacts with `package.json` `files` whitelist and documented peer/runtime dependency behavior in README.

## [0.1.0] - 2026-02-08
