StyleSeed makes expert design judgment repeatable by coding agents. Version 4.2.0 strengthens the project context, diagnostics, installation paths, and evidence needed to do that reliably.
What's new
- Project diagnostics: a read-only project doctor reports registry, compiled-context, and evidence state without rewriting approved decisions or inventing acceptance.
- Artifact-scoped workflows: build, component, and visual-verification guidance stays within the selected artifact and uses actual project paths/APIs.
- Windows reliability: corrected file-URL/path handling, clean PowerShell installation checks, and exit-code propagation that cannot hide an earlier failed check.
- Edge and stable channels: repository installs follow edge; release archives carry stable-channel metadata and compare against the published release manifest, not mutable main.
- Inspectable delivery: evaluator quickstart, external-app regression, browser evaluator calibration, signed source tag, checksums, two SBOMs, and GitHub attestations.
- Dependency maintenance: demo security updates and a graceful GitHub-star-count fallback.
Install
Install this version's core skills into a Codex project:
npx skills add https://github.com/bitjaru/styleseed/releases/download/v4.2.0/styleseed-core-4.2.0.tar.gz --agent codex --yes --copyThe repository install remains the edge channel:
npx skills add bitjaru/styleseedThe archive contains 23 physical core skills. Optional learning, ss-learn, and MCP are not included. This release does not publish a listing in the public Codex plugin directory.
Verification and assets
- Signed tag:
v4.2.0, targetingedb9cba7f3050b0aa7c1551d53a3c87c37b771e4. - Release preparation workflow: canonical source/build checks, production dependency audit, browser smoke, external-app regression, and browser evaluator calibration.
- Version PR and Windows/Linux checks.
- Six attached files: the core archive, inventory, release manifest, core SPDX SBOM, demo-production CycloneDX SBOM, and
SHA256SUMS.
After downloading all six files, verify their checksums (macOS):
shasum -a 256 -c SHA256SUMSVerify the core archive's source provenance with GitHub CLI:
gh attestation verify styleseed-core-4.2.0.tar.gz \
--repo bitjaru/styleseed \
--signer-workflow bitjaru/styleseed/.github/workflows/prepare-release.yml \
--source-ref refs/tags/v4.2.0 \
--source-digest edb9cba7f3050b0aa7c1551d53a3c87c37b771e4The attached manifest describes the immutable preparation stage (draft-prepared); publication is recorded by this GitHub release, not by rewriting the attested manifest afterward. Website deployment is a separate state.
Evidence limits
No new BENCH-V2 run, gate-effect claim, superiority claim, or expert-level visual-quality claim is made. The browser evaluator calibration covers 70 applicable normal cases, 15 intentional defects, and five execution-boundary probes; it is not an autonomous-agent trial or expert visual approval. BENCH-V1 remains historical evidence.
