+# Changelog
+
+All notable changes to this project are documented in this file.
+
+The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this
+project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). While the
+version is below 1.0.0, breaking changes are released in a minor bump.
+
+## [0.3.0] - 2026-07-24
+
+A library-wide audit of all three pillars — skills, agents, and archetypes — measured
+against Anthropic's Agent Skills guidance. Always-resident skill context is down 73%,
+the agents concept is gone, every archetype generates a project that runs, and the
+authoring rules are now enforced in CI rather than by discipline.
+
+### Removed
+
+- **The `agents/` directory and the agent concept.** The six "agents" were never Claude
+  Code subagents: four had no YAML frontmatter (so they installed with their H1 as the
+  entire description and were effectively untriggerable), all six installed into
+  `.claude/skills/` rather than `.claude/agents/`, `agent.toml` was never parsed by any
+  code path, and both "blocking" `action.yml` files ran `pixi` against a repo with no
+  `pixi.toml`. Roughly 77% of their content duplicated existing skills, often diverging
+  from them. GSD owns agency; whet owns domain knowledge, and knowledge is a skill.
+- **`whet install --agents-only` and `--skills-only` flags**, along with
+  `discover_agents()` and the `agents_dir` config field.
+- **Skills `dvc` and `cv-model-selection`.** Guidance that referenced DVC as a generic
+  concept was rewritten tool-neutral rather than left pointing at a deleted skill.
+
+### Added
+
+- **`model-evaluation`** — detection mAP/IoU via `supervision`, confusion matrices,
+  per-class and per-size breakdowns, deployment-threshold selection, per-slice failure
+  analysis, and eval-as-CI regression gates.
+- **`pydantic-ai`** — typed LLM/VLM structured outputs and VLM-in-the-loop auto-labeling.
+- **`data-pipelines`** — storage-format selection, group-aware leakage-preventing dataset
+  splitting, schema evolution, and data-quality validation.
+- **`whet install --prune`** — removes skills that no longer exist upstream. Scoped by a
+  `.whet-manifest.json` recording what whet installed, so skills placed in the same
+  directory by other tools are never touched.
+- **`whet install --include-extras`** and a `tier` field in `skill.toml`. Skills outside
+  the flagship path are opt-in: `aws-sagemaker`, `github-repo-setup`, `gradio`,
+  `huggingface`, `kubernetes`, `mlflow`, `vscode`.
+- **`whet init --with-recommended` / `--no-skills`.**
+- **Progressive disclosure** across the library: 29 of 32 skills are now a thin index
+  plus a `references/` directory loaded on demand — 155 reference files in total.
+- **CI enforcement.** A new `archetypes` job renders every archetype and runs the
+  toolchain against the generated project, plus guards for skill-authoring rules
+  (line ceiling, reference-link integrity, orphaned references, one-level-deep
+  references, tables of contents, trigger-first and third-person descriptions,
+  listing budget) and for archetype composition and documented directory trees.
+
+### Changed
+
+- **`whet init` now installs the archetype's skills** (with their `references/`) instead
+  of printing a `whet add ...` hint. An archetype's value over a folder copy is the skill
+  set it composes, so leaving that as homework made `[skills]` advisory.
+- **Skill `pydantic-strict` renamed to `pydantic`.**
+- **All skill descriptions rewritten** as third-person, trigger-first "use this skill
+  when…" statements with explicit disambiguation between adjacent skills. They were topic
+  summaries, which under-trigger.
+- **Every archetype template now generates a project that runs.** Previously four of six
+  generated only a four-file stub, and the two with templates produced projects that could
+  not import their own entry point, crashed on the first training step, or shipped no ONNX
+  despite being named for it. Template files went from 19 to 125.
+- **pixi is the canonical environment manager** for generated projects; manifests migrated
+  from the deprecated `[project]` table to `[workspace]`.
+- **Archetype skill composition** now reflects what each template actually ships — every
+  archetype requires `pixi` and `code-quality`, and `cv-inference-service` finally
+  requires `fastapi`.
+
+### Fixed
+
+- **The published wheel shipped no skills.** `[tool.hatch.build.targets.wheel]` packaged
+  only `src/whet`, and the bundled directories were resolved relative to the repository
+  root — so `uv tool install whet` produced a CLI that reported "No skills found" outside
+  a source checkout. The wheel now force-includes `skills/`, `archetypes/`, and
+  `settings/` under `whet/_data/`, and a single resolver prefers the packaged copy while
+  falling back to the repo layout for development.
+- Template files under a `data/` path were silently excluded by the repository's own
+  `.gitignore`, so a clean checkout produced projects missing `data/raw`, `data/processed`,
+  and an entire Hydra `data` config group.
+- `.ipynb` files were not treated as text by the scaffold engine, so `${package_name}`
+  inside a notebook was never substituted.
+- Adapters now install a skill's `references/` directory (Claude, Antigravity) or inline
+  it (Cursor, Copilot), so deep-dive links resolve on every platform.
+- Documented directory trees in archetype READMEs and docs pages are regenerated from the
+  templates; 78 documented-but-absent files were removed.
