alonso-skills/mssql-server

Writes, optimizes, and debugs T-SQL queries. Explains SQL Server internals, troubleshoots performance issues, and guides database administration tasks including backup/restore, high availability, security, and index design. Use when the user asks about T-SQL syntax, SQL Server administration, query performance, stored procedures, indexes, locking, transactions, backup/restore, high availability, security, or any MSSQL-related topic — even without saying 'SQL Server' explicitly. Also trigger on terms like SSMS, tempdb, bcp, sqlcmd, MSSQL, sp_executesql, NOLOCK, columnstore, Hekaton, RCSI, param sniffing, or execution plan.

Content

100%

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

This is an exceptionally well-structured skill that serves as a routing hub for a comprehensive SQL Server knowledge base. It is concise, actionable, and provides clear workflow instructions with excellent progressive disclosure across 54 reference files. The disambiguation column is a particularly strong feature that prevents ambiguity in topic routing.

DimensionReasoningScore

Conciseness

The skill is lean and efficient. It assumes Claude's competence with SQL Server, provides no unnecessary explanations of basic concepts, and uses a structured routing table format that maximizes information density. The quick examples are minimal but illustrative.

3 / 3

Actionability

The skill provides a clear, concrete workflow: identify topic via routing table, read the reference file, respond with code-first format. The quick examples include executable T-SQL. The routing table with 54 specific file mappings gives precise, unambiguous guidance on which reference to consult for any given topic.

3 / 3

Workflow Clarity

The 5-step workflow at the top is clearly sequenced and covers edge cases (cross-cutting questions, ambiguous keywords). The disambiguation column in the routing table explicitly handles overlapping topics with cross-references. The response format instruction (code → caveats → sources) provides a clear output template.

3 / 3

Progressive Disclosure

This is an exemplary progressive disclosure structure: a concise overview with quick examples, followed by a comprehensive routing table that points to 54 well-organized reference files. All references are one level deep with clear file paths and scope descriptions. The disambiguation column provides navigation guidance for overlapping topics.

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.

This is an excellent skill description that covers all evaluation dimensions at the highest level. It provides specific concrete actions, comprehensive trigger terms spanning both common and advanced SQL Server terminology, explicit 'Use when' guidance, and a clearly distinctive niche that would not conflict with other database-related skills.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: writes/optimizes/debugs T-SQL queries, explains SQL Server internals, troubleshoots performance issues, guides database administration tasks including backup/restore, high availability, security, and index design.

3 / 3

Completeness

Clearly answers both 'what' (writes/optimizes/debugs T-SQL, explains internals, troubleshoots performance, guides admin tasks) and 'when' with an explicit 'Use when...' clause listing comprehensive trigger scenarios and specific terms.

3 / 3

Trigger Term Quality

Excellent coverage of natural terms users would say, including both common terms (T-SQL, SQL Server, stored procedures, indexes, backup/restore) and specialized terms (SSMS, tempdb, bcp, sqlcmd, MSSQL, sp_executesql, NOLOCK, columnstore, Hekaton, RCSI, param sniffing, execution plan). Also notes triggering even without explicit 'SQL Server' mention.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive with a clear niche around SQL Server/T-SQL/MSSQL. The specific product names, tools (SSMS, sqlcmd, bcp), and internal concepts (Hekaton, RCSI, param sniffing, columnstore) make it very unlikely to conflict with generic database or other RDBMS skills.
