Investigate .NET CI failures using the hlx CLI tool via bash. USE FOR: checking Helix job status, searching build logs, downloading test results, AzDO build timeline analysis — when MCP tools aren't loaded, when the MCP server isn't configured or fails to start, or when scripting with JSON output and jq. DO NOT USE…

Completion-safe bucketing for Helix work items with nullable exit codes.
Skill Claude CodeCodex
Purpose: Look up all Helix jobs for an AzDO build using the canonical Job.ListAsync(source) + BuildId filter pattern, instead of scraping AzDO timeline task names.

Updated: 2026-05-28 (CallToolFilters middleware implemented + schema audit findings captured).
Skill Claude CodeCodex
Purpose: Audit a set of MCP tool methods for exception handling hygiene and McpException wrapping compliance.
Skill Claude CodeCodex
Purpose: Add unhappy-path tests proving MCP tool methods convert service failures into user-visible McpException messages instead of silent/null MCP failures.
Skill Claude CodeCodex
Design filter/enum parameters for MCP tools consumed by LLM clients, balancing expressiveness with discoverability.
Skill Claude CodeCodex
Rename MCP tool parameters when the wire schema drifted from semantic intent.

How to evaluate and land a major-version upgrade of the ModelContextProtocol C# SDK (e.g. 1.x → 2.x) in this repo.
Skill Claude CodeCodex
Keep MCP tool parameter schemas consistent across sibling tools that share a conceptual resource (e.g., jobId + workItem).
Skill Claude CodeCodex
Strict unknown-parameter rejection for MCP tools: Stage A (UnmappedMemberHandling.Disallow) + Stage B (did-you-mean CallToolFilter).
Skill Claude CodeCodex
Use this only for tiny results where schema carries little value and you must keep the actual tool-call payload stable.

Use this skill whenever Larry asks to cut a release (e.g., "prep vX.Y.Z release").
