71%Scale 1-5Reviews 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 covering the key implementation patterns (RLS, middleware, ORM scoping). Its main weakness is verbosity — the edge cases, best practices, and 'never do this' sections, while individually valuable, make the file long enough to warrant splitting into referenced files. The workflow is clear and well-sequenced but could benefit from explicit verification/testing checkpoints after critical steps like RLS setup.
Suggestions
Split 'Edge Cases', 'Best Practices', and 'Never Do This' into separate referenced files (e.g., EDGE_CASES.md, BEST_PRACTICES.md) to reduce the main file's token footprint and improve progressive disclosure.
Add an explicit verification step after RLS setup, such as: 'Test: connect as app user, SET app.current_tenant_id to tenant A, SELECT from table — verify only tenant A rows return. Then SET to tenant B and confirm isolation.'
Trim explanatory rationale that Claude can infer — e.g., 'Sequential IDs let attackers enumerate other tenants' resources by incrementing the ID' can be shortened to 'Sequential IDs enable enumeration attacks across tenants.'
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill contains valuable, non-obvious information but is noticeably verbose in places. Step 1's discussion of tenancy model tradeoffs, some of the 'Never Do This' explanations, and the 'Best Practices' section include rationale that Claude could infer. The edge cases section, while useful, adds significant length. However, most content is domain-specific knowledge Claude wouldn't inherently know (RLS patterns, SET LOCAL gotchas, Prisma middleware specifics). | 3 / 5 |
Actionability | The skill provides fully executable SQL for RLS policies, complete TypeScript middleware for Express with proper error handling and connection cleanup, and a working Prisma middleware with edge case handling (createMany, global tables). All three examples are copy-paste ready and cover the most common implementation patterns. The workflow steps give specific commands and patterns rather than vague directions. | 5 / 5 |
Workflow Clarity | The 8-step core workflow is clearly sequenced and logically ordered (determine model → add columns → set up RLS → build middleware → scope ORM → migrations → admin routes → provisioning). Step 8 includes a transaction-based validation checkpoint. However, there's no explicit verification step after RLS setup (e.g., 'test that an unscoped query returns only tenant data') and no feedback loop for validating the middleware is correctly scoping queries. The 'Never Do This' section partially compensates by highlighting failure modes. | 4 / 5 |
Progressive Disclosure | The content is well-structured with clear sections (Core Workflow, Examples, Never Do This, Edge Cases, Best Practices), but at ~200+ lines it would benefit from splitting edge cases, best practices, or the examples into separate referenced files. There are no bundle files and no references to external documents. The monolithic structure means Claude loads all content even when only the core workflow or a single example is needed. | 3 / 5 |
