relational-database-mcp-cloudbase

[Deprecated] This is the required documentation for agents operating on the CloudBase Relational Database through MCP. It defines the canonical SQL management flow with `queryMysqlDatabase`, `manageMysqlDatabase`, `queryPermissions`, and `managePermissions`, including MySQL provisioning, destroy flow, async status checks, safe query execution, schema initialization, and permission updates. New environments should use PostgreSQL — see postgresql-development skill instead.

Quality

Content

73%Weight 40%Scale 1-5

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

The body is well-structured and highly actionable, with sequenced lifecycle workflows that include explicit validation and feedback loops for destructive operations. Its main weakness is redundancy across the activation, usage, and tool-selection sections, which inflates token cost without adding new guidance.

Suggestions

Consolidate the 'Activation Contract', 'When to use this skill', and 'How to use this skill' sections into a single trigger + tool-selection block to eliminate repeated tool-to-purpose mapping.

Move the full per-tool reference into a separate references file and keep only the call shapes inline, tightening the SKILL.md overview.

Add one complete end-to-end example (input call through expected output) for a common case like provisioning then initializing a table.

DimensionReasoningScore

Conciseness

It avoids explaining concepts Claude already knows, but the Activation Contract, 'When to use this skill', and 'How to use this skill' sections substantially repeat the same tool-to-purpose mapping, so it could be tightened.

3 / 5

Actionability

Provides concrete, mostly executable guidance — explicit call shapes like queryPermissions(action="getResourcePermission", resourceType="sqlDatabase", resourceId="<tableName>"), a runQuery JSON example, and the _openid DDL snippet — with only minor gaps such as no full end-to-end example with expected output.

4 / 5

Workflow Clarity

The five lifecycle scenarios are clearly sequenced with explicit validation checkpoints (confirm=true, read-before-write), feedback loops (poll describeCreateResult/describeTaskStatus until READY or terminal), and error-recovery guidance for the destroy flow.

5 / 5

Progressive Disclosure

Content is organized into clear headed sections and points to sibling skills via one-level-deep relative paths (../relational-database-web-cloudbase/SKILL.md, ../http-api-cloudbase/SKILL.md) that are clearly signaled; the inline per-tool reference is reasonable but the redundant trigger sections are a minor organization gap.

Description

75%Weight 40%Scale 1-5

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

The description is specific and well-differentiated, naming concrete capabilities and tools while clearly scoping itself to MCP agent operations. Its main weakness is the absence of an explicit 'Use when...' trigger clause, which leaves the activation timing implied rather than stated.

Suggestions

Add an explicit 'Use when...' sentence with natural trigger phrases (e.g., 'Use when provisioning or destroying MySQL, running SQL via MCP, or managing SQL table permissions through CloudBase').

Reduce reliance on raw tool names as triggers by adding user-facing synonyms such as 'relational database', 'MySQL instance', and 'SQL security rules'.

Lead with the active capability rather than the '[Deprecated]' tag so the 'what' is immediately legible before the migration note.

DimensionReasoningScore

Specificity

Lists multiple concrete actions (MySQL provisioning, destroy flow, async status checks, safe query execution, schema initialization, permission updates) alongside the four named MCP tools, giving comprehensive coverage of capabilities.

5 / 5

Completeness

It clearly answers 'what' the skill does, but provides no explicit 'Use when...' trigger clause; the 'when' is only weakly implied by 'for agents operating on the CloudBase Relational Database through MCP', capping completeness at 3 per the missing-trigger guideline.

3 / 5

Trigger Term Quality

Includes natural terms users would say (MySQL, SQL, permissions, schema, provisioning) but leans heavily on technical tool names and omits common synonyms or a plain 'Use when...' trigger phrase, leaving a few natural terms missing.

4 / 5

Distinctiveness Conflict Risk

It carves a clear MCP-agent niche and explicitly distinguishes itself from SDK skills and the postgresql-development alternative, giving minimal conflict risk with other skills.
