* .NET: Add Hosted-AgentSkills sample for Foundry Skills integration Add a new hosted agent sample that demonstrates how to load behavioral guidelines from Foundry Skills at startup using AgentSkillsProvider and the progressive disclosure pattern (advertise -> load on demand). The sample: - Downloads SKILL.md files from Foundry via ProjectAgentSkills SDK - Extracts ZIP archives with zip-slip protection - Wires skills into AgentSkillsProvider as an AIContextProvider - Hosts the agent via the Responses protocol Ships two Contoso Outdoors skills matching the Python sample (PR #5822): - support-style: tone, formatting, signature guidelines - escalation-policy: when and how to escalate tickets Includes convenience provisioning gated behind PROVISION_SAMPLE_SKILLS env var, clearly documented as NOT a production pattern. Closes #5776 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * .NET: Add unit tests and integration test for Hosted-AgentSkills Unit tests (14 tests, all passing): - ZIP extraction with zip-slip guard (valid archive, traversal attack, sibling-prefix attack, directory entries) - Skill name validation (rejects dots, separators, traversal patterns) - AgentSkillsProvider with downloaded skills (advertises both skills, load_skill returns canary tokens, unknown skill returns error) Container integration test: - New 'agent-skills' scenario in the test container that creates Contoso Outdoors skills on disk and wires AgentSkillsProvider - AgentSkillsHostedAgentFixture + 4 integration tests verifying: - Routine questions load support-style skill (STYLE-CANARY-3318) - Escalation triggers load escalation-policy (ESC-CANARY-7742) - Skills are advertised in system prompt - load_skill tool is invoked via FunctionCallContent Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * .NET: Add smoke test, bootstrap, and docs for agent-skills integration - Add scripts/smoke.ps1 for local Docker smoke testing: builds the contributor image, runs the container, verifies both skills are loaded via canary tokens (STYLE-CANARY-3318, ESC-CANARY-7742) - Add 'agent-skills' to the bootstrap script scenario list - Add agent-skills row to the integration test README scenarios table - Exclude HostedAgentSkillsPatternTests from net472 (uses net8.0+ APIs) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * .NET: Update commented-out package versions to latest across all hosted samples Update the end-user PackageReference versions (in the commented-out sections) from 1.0.0 to the current latest NuGet versions: - Microsoft.Agents.AI: 1.6.1 - Microsoft.Agents.AI.Foundry: 1.6.1-preview.260514.1 - Microsoft.Agents.AI.Foundry.Hosting: 1.6.1-preview.260514.1 - Microsoft.Agents.AI.Hosting: 1.6.1-preview.260514.1 - Microsoft.Agents.AI.OpenAI: 1.6.1 - Microsoft.Agents.AI.Workflows: 1.6.1 Also adds explicit versions to Hosted-Workflow-Handoff which had bare PackageReference entries without Version attributes. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * .NET: Fix broken markdown links in Hosted-AgentSkills README Remove references to non-existent ../../README.md. Replace with inline instructions matching other hosted samples that don't have a parent README. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * .NET: Use OS-appropriate string comparison in zip-slip guard Use Ordinal on Unix (case-sensitive FS) and OrdinalIgnoreCase on Windows to prevent case-based path bypass on Linux containers.
