Based on SOC occupation classification
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 FOR: tasks where Helix/AzDO MCP tools are already available in context (prefer ci-analysis skill when MCP server is loaded). INVOKES: bash (hlx CLI commands with --json output).
{what this skill teaches agents}
Audit pattern for comparing WorkItemSummary (list API) fields against WorkItemDetails (per-item API) after a Helix.Client SDK bump
Domain-layer normalizer + JSON-stable cache key pattern for filter types with server-side defaults and case-insensitive fields.
Strict unknown-parameter rejection for MCP tools: Stage A (UnmappedMemberHandling.Disallow) + Stage B (did-you-mean CallToolFilter).
Audit MCP/CLI tool parameter surface against underlying REST API capabilities to find silently-dropped params.

Use this when an MCP tool should expose a small, canonical enum in AllowedValues, but callers may realistically send adjacent platform spellings or natural-language synonyms.
AllowedValues limited to the canonical names you want in the schema.inProgress, in-progress, and active as silent aliases for canonical running.notStarted and not-started as silent aliases for canonical pending.AllowedValues, forcing callers to choose between synonyms.
