devserver

Build, test, and maintain the Uno DevServer (CLI tool, RemoteControl Host, MCP proxy, add-in discovery). Use when working under src/Uno.UI.DevServer.Cli, src/Uno.UI.RemoteControl.Host, or src/Uno.UI.RemoteControl.DevServer.Tests, or on DevServer CLI commands, the MCP proxy, IDE channel, or add-in resolution.

Quality

Content

100%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A lean, information-dense reference that assumes Claude's competence and supplies concrete commands, exact file targets, and verification steps across clearly sequenced sections. It appropriately defers depth to one-level-deep referenced docs.

DimensionReasoningScore

Conciseness

Dense and project-specific — file names, paths, behaviors, and retry counts — with no boilerplate explaining ASP.NET Core, MSBuild, or MCP that Claude already knows, so every token earns its place.

3 / 3

Actionability

Provides copy-paste-ready 'dotnet build'/'dotnet test' commands and maintenance tasks that name exact files to edit (CliManager.cs, Program.cs, run-devserver-cli-tests.ps1), matching the 'fully executable; copy-paste ready' anchor.

3 / 3

Workflow Clarity

Numbered sections, a connection-state lifecycle diagram, documented retry counters, and maintenance tasks with explicit verification steps ('verify with uno-devserver disco --json', 'test with --mcp-app + an MCP client') give clear sequences with checkpoints.

3 / 3

Progressive Disclosure

Nine well-organized sections serve as an overview, and section 9 points one level deep to dedicated docs (dev-server.md, health-diagnostics.md, addin-discovery.md, specs/001-fast-devserver-startup/) with no nested reference chains; no bundle directories exist to verify against.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that states concrete capabilities and pairs them with an explicit 'Use when...' trigger clause scoped to specific source paths and feature areas. It is distinctive, complete, and free of vague fluff.

DimensionReasoningScore

Specificity

Lists three concrete action verbs ('Build, test, and maintain') tied to four named components (CLI tool, RemoteControl Host, MCP proxy, add-in discovery), matching the 'multiple specific concrete actions' anchor rather than the 'some actions' level below.

3 / 3

Completeness

Explicitly answers both 'what' (build/test/maintain the Uno DevServer and its components) and 'when' via a literal 'Use when...' clause enumerating paths and feature areas, matching the 'clearly answers both what AND when' anchor.

3 / 3

Trigger Term Quality

Natural trigger terms for this codebase ('DevServer CLI commands', 'MCP proxy', 'IDE channel', 'add-in resolution') plus concrete src/ paths give good coverage of what a developer would actually say, matching the 'good coverage of natural terms' anchor.

3 / 3

Distinctiveness Conflict Risk

A narrow, product-specific niche anchored to unique paths and component names makes it unlikely to trigger for any other skill; written in third person so no voice penalty applies.
