[GitHub release](https://github.com/outfitter-dev/skillset/releases/tag/v0.27.0) · [Package changelog](https://github.com/outfitter-dev/skillset/blob/24800e02ed4e7150ea1bc7130c35603c98ea9da2/apps/skillset/CHANGELOG.md)

## Publication

Published the seven-package Skillset 0.27.0 set to npm with dist-tag `latest`.

## Changes

### Minor Changes

- 545a73f: Adopt the validated Agent Instructions, Agent Skills, and Agent Plugins profiles so default builds emit their inherent standards projections with pinned conformance evidence.
- b0f6b1c: Remove standards selection from source configuration and add Agent Skills `compatibility` plus `allowed_tools.agents`. Standards remain distinct from provider targets, and an explicit empty `compile.targets` selection is available for applicable adopted standards output. Normal builds gain each inherent applicable standard when its profile is adopted; pre-v3 generated locks require an owner-reviewed one-time rebuild and never authorize cleanup.
- 21940a2: Generate individually installable Agent Skills from self-contained plugin source while diagnosing plugin dependencies and skill-local hooks that cannot survive standalone installation.
- ec70bf5: Generate one repository-owned ChatGPT marketplace catalog from ordered Skillset marketplace source, with closed native source, policy, listing fallback, and interface mappings.
- b863f40: Render the Codex-selected ChatGPT product bundle as an Agent Plugins root with a closed OpenAI extension, portable Agent Skills and MCP components, deterministic ownership locks, and pinned OpenAI consumer evidence.
- 774b9de: Add a public registry surface for immutable candidate Agent Instructions,
  Agent Skills, and Agent Plugins 1.0 evidence, including offline plugin and MCP
  schema snapshots and report-only drift checks.

### Patch Changes

- e792ac3: Render Agent Instructions independently from provider selection, coalesce shared Codex `AGENTS.md` output under one standard owner, and honor explicit Agent Instructions opt-outs without recreating provider fallback files.
- ccc667b: Render Agent Plugins 1.0 package manifests and neutral support files under `plugins/<plugin>/agents`, preserve standard ownership in the shared lock, report provider-only components as uncovered without leaking them into the standard package, and reject symlinked or out-of-scope license inputs before reading them.
- d25e439: Render Agent Skills baselines for standalone and plugin-owned skills, coalesce compatible Codex skill trees with standard ownership, reject resource symlink escapes, and report standard-invalid components without suppressing valid provider output.
- 16830c0: Fix implicit Claude marketplace catalogs so local plugin sources are not rebased twice by consumers.
- cb9704c: Render canonical listing display names into Claude plugin manifests while preserving provider-native and marketplace label precedence.
- 7c5143a: Coalesce standard baselines and provider deltas into one deterministic physical output plan, and safely clean inactive standard roots across live and isolated builds.
- efe5cc7: Render versioned, flat Cursor plugin hook handlers from existing grouped hook source, preserve validated Cursor-native handler fields, omit portable status text that has no Cursor destination, and reject malformed flat handlers that previously bypassed validation.
- 24bb38b: Lower canonical `implicit_invocation` to Cursor `disable-model-invocation` with inverse polarity, preserve native override precedence, and scope adopted provider-native invocation policy so it cannot leak into unrelated targets.
- 953809b: Read current generated locks and render results through validated, versioned
  readers while preserving lock identity and logical-consumer evidence. Diagnose
  pre-v3 generated state as a coordinated rebuild instead of granting it cleanup
  authority.
- 1c2c8cb: Import Agent Plugins 1.0 packages into canonical plugin source, including portable metadata, skills, MCP configuration, and recognized support files, while blocking unmappable extensions before adoption writes.
- ebadb1f: Document Agent standards as inherent adopted projections, distinguish project-agent and provider configuration from standards, enforce Agent Skills names in `skillset new skill`, and clarify the generated CI scaffold.
- 6008bf9: Add version-qualified provider location evidence for distinct Claude, Codex, Cursor, and ChatGPT surfaces and expose it through the static lookup API and CLI.
- c338af7: Refresh the exact hosted provider validator evidence and expose receipt-based freshness assessment for maintenance tooling.
- 1926f66: Keep command-only build mode overrides out of generated lock provenance so later default status, check, diff, and update commands remain current.
- 0c783cf: Expose standard-profile lifecycle, scope, evidence, ownership, and consumer
  identity across CLI and JSON inspection surfaces while keeping provider
  activation readiness separate from standards conformance.
- 72447c0: Derive inherent Agent standards projections from applicable source and adopted registry profiles, independently from provider target selection.
- f5fb227: Track SEP-2640 as an immutable candidate standard and record OpenAI's separate plugin-submission skill importer limits.
- 20bd533: Parse plugin MCP source into one portable model, validate the Agent Plugins contract, render provider bundle bytes from that model, emit standard `mcp.json`, and rewrite provider dialects during import.
