• Standardize file skills terminology on 'directory' (#5205)

  Rename authored identifiers, XML docs, log messages, and comments
  from 'folder' to 'directory' across the file skills codebase for
  consistency with the agentskills.io specification and .NET conventions.
  
  Public API changes (experimental):
  - ScriptFolders → ScriptDirectories
  - ResourceFolders → ResourceDirectories
  
  .NET BCL API calls (Directory.Exists, Path.GetDirectoryName, etc.)
  were already using 'directory' and are unchanged.

• .NET: Support reflection for discovery of resources and scripts in class-based skills (#5183)

  * support reflection for discovery of resources and scripts in class-based skills
  
  * fix format issues
  
  * refactor samples to use reflection
  
  * Validate resource member signatures during discovery
  
  Add discovery-time validation in AgentClassSkill.DiscoverResources() to
  fail fast when [AgentSkillResource] is applied to members with incompatible
  signatures:
  
  - Reject indexer properties (getter has parameters)
  - Reject methods with parameters other than IServiceProvider or
    CancellationToken
  
  Throws InvalidOperationException with actionable error messages instead of
  allowing silent runtime failures when ReadAsync invokes the AIFunction with
  no named arguments.

  * .NET: Add JsonSerializerOptions support to programmatic skill APIs
  
  Allow callers to pass custom JsonSerializerOptions when creating inline
  resources and scripts via AgentInlineSkill, AgentClassSkill,
  AgentInlineSkillResource, and AgentInlineSkillScript. A skill-level
  default can be set on AgentInlineSkill and overridden per-resource/
  script call.

• .NET: Add API breaking change validation for RC packages (#4977)

  * Add API breaking change validation for RC packages
  
  Enable .NET Package Validation for release candidate packages to detect
  API breaking changes in CI. This follows the same pattern used by
  Semantic Kernel, centralized through nuget-package.props.
  
  Changes:
  - Enable EnablePackageValidation for IsReleaseCandidate packages
  - Update PackageValidationBaselineVersion to 1.0.0-rc4 (latest published)
  - Generate CompatibilitySuppressions.xml for existing known API changes
    in 5 packages (AI, AzureAI, OpenAI, Workflows, Workflows.Declarative.AzureAI)
  - Opt out Workflows.Declarative.Mcp (not yet published to NuGet)
  - Add breaking changes guidance to CONTRIBUTING.md
  
  Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
  
  * Address PR review feedback
  
  - Remove unnecessary empty PackageValidationBaselineVersion override
    in Workflows.Declarative.Mcp.csproj (EnablePackageValidation=false
    is sufficient)
  - Tighten CONTRIBUTING.md wording to clarify opt-out possibility
  
  Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
  
  * Enable package validation for GA packages (no VersionSuffix)
  
  Expand the EnablePackageValidation condition to also cover future GA
  packages that have no VersionSuffix, not just RC packages.
  
  Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
  
  * Fix EnablePackageValidation GA condition to check PackageVersion
  
  The previous condition VersionSuffix=='' matched all packages (preview
  included) since VersionSuffix defaults to empty. Now uses two separate
  conditions: one for RC, one for true GA (PackageVersion == VersionPrefix).
  
  Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
  
  * Add IsGeneralAvailable flag for package validation
  
  Replace fragile PackageVersion condition with explicit IsGeneralAvailable
  property, following the same per-project self-declaration pattern as
  IsReleaseCandidate.
  
  - Directory.Build.props: Add IsGeneralAvailable=false default
  - nuget-package.props: EnablePackageValidation on RC OR GA
  - CONTRIBUTING.md: Update docs to mention both flags
  
  When packages go GA, they set IsGeneralAvailable=true in their .csproj.
  
  Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
  
  * Rename IsGeneralAvailable to IsGenerallyAvailable

• .NET: Validate SkillsInstructionPrompt contains {0} placeholder in FileAgentSkillsProvider (#4642)

  * Fix FileAgentSkillsProvider accepting SkillsInstructionPrompt without {0} placeholder (#4638)
  
  BuildSkillsInstructionPrompt validated only format-string syntax via
  string.Format(template, ""), which silently accepted templates without a
  {0} placeholder. The generated skills list was then dropped from the final
  instructions.
  
  Tighten validation to format with a sentinel string and verify it appears
  in the output, rejecting templates that do not reference argument 0 with
  an ArgumentException.

    template string using IndexOf
  - Add positive test verifying custom SkillsInstructionPrompt with {0}
    is accepted and applied to output
