This pull request introduces significant improvements to the FeatBit agent skills documentation and project structure, focusing on clarity, best practices, and skill authoring guidance. It adds comprehensive best-practice documentation for skill builders, replaces the generic skill description for feature flags with a more focused and actionable skill, and removes redundant or duplicate scripts. Additionally, it removes an unnecessary commit message instruction file.

Documentation and Authoring Best Practices:

• Added a detailed best-practice guide for skill builders in .github/prompts/skill-builder-best-practice.prompt.md, covering project structure, naming conventions, frontmatter requirements, writing style, workflow formatting, reference file management, versioning, and release processes. This guide ensures all contributors follow consistent and high-quality standards when authoring or updating skills.

Skill Content and Structure Updates:

• Replaced the generic featbit-skills skill (.github/skills/featbit/SKILL.md) with a new, focused featureflags skill (.agents/skills/featureflags/SKILL.md). The new skill provides step-by-step guidance for integrating feature flags into FeatBit MCP Server tools and code paths, including clear instructions on when and how to use feature flags, best practices, and code examples for both tool gating and conditional logic.

Code and Script Cleanup:

• Removed duplicate or redundant scripts for listing feature flags and enabling/disabling feature flags (.github/skills/featbit/list-feature-flags/script.js, .github/skills/featbit/enable-disable-feature-flag/script.js), likely because these are now covered by more maintainable or centralized documentation and workflows.

Project Hygiene:

• Removed the outdated or unnecessary commit message instruction file .copilot-commit-message-instructions.md to avoid confusion and enforce the new commit message standards described in the best-practice documentation.
