Summary

• Move Azure CLI target inference, changed test selection, regression coverage, AAZ source routing and CLI Extensions handoff into repository owned .x/skills.
• Update .x/x.yml to map the custom functions and approve only the scope bound shared primitives they require.
• Update the agent charters to call the repository owned skills explicitly.

Security

• Keep authentication, sensitive data enforcement, immutable policy loading, repository scoping and narrow GitHub mutations in the central runtime
• Resolve repository target roots and base branches from trusted central configuration rather than custom skill arguments

🟡 Changes recommended

The updated Tester charter omits the required repo_full_name="Azure/azure-cli" argument when instructing calls to infer_target_for_repo, which would cause the workflow to fail at runtime.

Pull request overview

This PR migrates several Azure CLI agent capabilities (target inference, changed-test selection, regression coverage, AAZ generation-source routing, and CLI Extensions handoff) from the shared/base skill set into repository-owned custom skills under .x/skills, and updates the agent charters and .x/x.yml wiring accordingly.

Changes:

• Adds repository-owned custom skills for changed-test selection, target inference, regression coverage, AAZ source promotion/routing, and extensions handoff.
• Updates .x/x.yml to map custom skill entrypoints and to include the required scope-bound shared primitives.
• Updates agent role charters (.x/*.md) to explicitly reference repository-owned custom skills.
