Changelog
0.2.4 - 2026-11-08
- Add an explicit Claude manifest for claude.ai marketplace synchronization.
0.2.3 - 2026-10-10
- Require Agent Plugins conformance before release, with validation evidence for the exact release candidate.
- Require explicit native-only exception documentation covering the client limitation, compatibility limits, reproducible evidence, native checks, and the condition for reconsidering portability.
0.2.2 — 2026-10-04
- Validate safe pinned external Git catalog sources alongside contained local entries.
- Add metadata-only entry validation without claiming portable-package validation.
- Add cross-platform synthetic regression coverage and document isolated-install migration checks.
0.2.1 - 2026-08-27
- Accept Codex's versioned
<plugin>/<version>/installed-cache layout during portable package validation while retaining strict source-directory identity checks. - Add installed-cache coverage and document direct validation of installed package bytes.
0.2.0 - 2026-08-07
- Added portable Agent Plugins 1.0.0 as an explicit package target with canonical root manifests and fixed component discovery.
- Added bundled canonical schemas and an
uv-native validator for schema, path, MCP transport, secret, OpenAI overlay, and marketplace conformance. - Added a portable-plus-OpenAI target and migrated the builder package itself to that layout.
- Added an explicit MCP 2026-07-28 compatibility gate covering Codex opt-in, discovery, stateless metadata, multi-round input, pagination, caching, subscriptions, and deprecations.
- Removed machine-specific validation paths in favor of active skill roots and cross-platform
uv runcommands.
