V0.8.2/patch behaviour

[gimlichael]

This pull request is a patch release (v0.8.2) focused on skill refinement and documentation updates, with an emphasis on deprecating skill-creator-agnostic in favor of Anthropic's skill-creator, expanding and clarifying documentation for several skills, and improving repository guidance. The most important changes include deprecation notices and removal of skill-creator-agnostic from recommendations, major workflow and documentation enhancements for git-keep-a-changelog, and improved guidance for other skills.

Skill Deprecation and Documentation Updates

• skill-creator-agnostic is now explicitly deprecated, no longer maintained, and scheduled for removal in 1.0.0. All documentation (including README.md and AGENTS.md) now directs users to use Anthropic's skill-creator with repository-specific rules instead. It is removed from recommended install lists and its SKILL.md is now a deprecation shim. [1] [2] [3] [4] [5] [6]

Skill Workflow and Guidance Improvements

• git-keep-a-changelog: Expanded with step-by-step workflow sections, a deterministic reduction model for semantic-delta analysis, mandatory release highlight contract, checkpoint enforcement, and improved documentation of good/bad output characteristics and user-intent gates. SKILL.md is refactored to include these changes.
• git-nuget-release-notes and git-visual-squash-summary: Documentation and eval coverage are enhanced, including improved guidance on workflow, history reduction, and semantic grouping. [1] [2] [3]

Repository Guidance and Third-party Skills Policy

• AGENTS.md is updated to clarify that third-party skills (like Anthropic's skill-creator) must not be modified or wrapped with overlays; repo-specific behavior should be documented only in AGENTS.md.

Changelog and Versioning

• CHANGELOG.md is updated with detailed entries for v0.8.2 and v0.8.1, including all major documentation, workflow, and deprecation changes. Compare links for the new versions are added. [1] [2]

Skill Validation Tooling

• Skill validation scripts are enhanced to better check skill content, structure, and consistency, with new eval coverage for validation behavior.

These changes ensure that users follow up-to-date, reliable workflows, avoid deprecated tools, and have clear, enforced guidance for skill authoring and repository management.

Filename	Overview
AGENTS.md	Adds the deprecation policy and clarifies that repository-specific rules must not be implemented as third-party skill overlays.
