neo4j-graphql-skill

Build and configure a GraphQL API backed by Neo4j using @neo4j/graphql v7 (current) or v5 (LTS). Covers Neo4jGraphQL constructor, getSchema(), assertIndexesAndConstraints(), type definitions with @node, @relationship (IN/OUT/UNDIRECTED), @cypher for custom resolvers, @authorization/@authentication for JWT/JWKS security, auto-generated queries/mutations, OGM programmatic access, subscriptions via CDC, and Apollo Federation. Use when writing typeDefs, securing fields, or wiring Neo4j to Apollo Server. Does NOT handle raw Cypher outside resolvers — use neo4j-cypher-skill. Does NOT cover Spring Data Neo4j entity mapping — use neo4j-spring-data-skill.

Quality

Content

77%

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

This is a strong, highly actionable skill with excellent executable examples, a clear workflow progression, and a useful common errors table. Its main weakness is length — at ~350 lines it packs substantial detail that could benefit from splitting into bundle files for progressive disclosure. Some explanations of concepts Claude already understands (direction semantics, filter vs validate descriptions) add modest bloat.

Suggestions

Split detailed sections (Security, OGM, Subscriptions, Migration) into separate bundle files and reference them from a leaner SKILL.md overview to improve progressive disclosure and conciseness.

Remove explanatory prose Claude already knows (e.g., 'Direction rule: OUT = arrow leaves this node') and rely on the code examples which already demonstrate the concepts clearly.

DimensionReasoningScore

Conciseness

The skill is comprehensive and mostly efficient, but some sections are verbose for Claude — e.g., explaining what direction OUT/IN means, the 'filter vs validate' explanation, and the 'When to Use / When NOT to Use' section could be tighter. The Connection API explanation and some directive descriptions include context Claude likely already knows. However, the tables and code examples are well-structured and dense.

2 / 3

Actionability

Excellent actionability throughout — fully executable code examples for server setup, type definitions, OGM usage, security configuration, and mutations. Code is copy-paste ready with real imports, environment variables, and complete GraphQL queries. The common errors table maps directly to specific fixes.

3 / 3

Workflow Clarity

The skill follows a clear sequential workflow (Install → Server Setup → Directives → Security → Operations → OGM → Subscriptions) with explicit validation checkpoints like assertIndexesAndConstraints with try/catch guidance, and a comprehensive checklist at the end. The common errors table serves as a troubleshooting feedback loop.

3 / 3

Progressive Disclosure

The content is well-organized with clear sections and a logical hierarchy, but it's a monolithic ~350-line file with no bundle files to offload detailed content. The security section, OGM section, and directive reference could each be separate files referenced from a leaner overview. External references are provided but only as links to Neo4j docs, not to bundle files.

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 thoroughly covers specific capabilities, includes abundant natural trigger terms, explicitly states both what it does and when to use it, and proactively delineates boundaries with related skills. The negative boundary clauses pointing to alternative skills are a particularly strong feature for disambiguation. The description uses proper third-person voice throughout.

DimensionReasoningScore

Specificity

Lists numerous specific concrete actions and concepts: Neo4jGraphQL constructor, getSchema(), assertIndexesAndConstraints(), type definitions with @node, @relationship, @cypher, @authorization/@authentication, auto-generated queries/mutations, OGM, subscriptions via CDC, and Apollo Federation.

3 / 3

Completeness

Clearly answers both 'what' (build/configure GraphQL API with Neo4j, covering specific decorators, security, OGM, subscriptions, federation) and 'when' ('Use when writing typeDefs, securing fields, or wiring Neo4j to Apollo Server'). Also includes explicit negative boundaries directing to other skills.

3 / 3

Trigger Term Quality

Includes strong natural keywords users would say: 'GraphQL API', 'Neo4j', 'typeDefs', 'Apollo Server', '@neo4j/graphql', 'JWT/JWKS', 'OGM', '@relationship', '@authorization', 'subscriptions', 'Apollo Federation'. These cover the terms a developer working in this space would naturally use.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive with explicit boundary statements ('Does NOT handle raw Cypher outside resolvers — use neo4j-cypher-skill. Does NOT cover Spring Data Neo4j entity mapping — use neo4j-spring-data-skill.') that actively prevent conflicts with related skills. The niche of @neo4j/graphql is very specific.
