bwfc-identity-migration

**WORKFLOW SKILL** — Migrate ASP.NET Web Forms Identity and Membership authentication to Blazor Server Identity. Covers OWIN→Core middleware, login/register/logout minimal API endpoints, BWFC login controls, cookie auth under Interactive Server, and role-based authorization. WHEN: "migrate identity", "login page migration", "OWIN to core", "cookie auth blazor", "LoginView migration". INVOKES: dotnet CLI for identity scaffolding. FOR SINGLE OPERATIONS: use bwfc-migration for markup, bwfc-data-migration for EF.

Quality

Content

42%

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

The skill excels at actionability with comprehensive, executable code examples covering the full identity migration workflow. However, it is severely undermined by extreme verbosity and redundancy — key concepts like DisableAntiforgery and LoginView guidance are repeated 3-4 times each, and content that should live in the referenced IDENTITY-PATTERNS.md companion is fully inlined. Adding validation checkpoints between migration steps would improve workflow safety for this inherently risky operation.

Suggestions

Move the detailed endpoint templates, OWIN mapping table, gotchas section, and authorization pattern examples into IDENTITY-PATTERNS.md, keeping only the quick reference table and one canonical endpoint example in SKILL.md

Eliminate redundant explanations: consolidate DisableAntiforgery into one location (Critical Rules + one code comment), remove the duplicate BWFC controls table, and state the LoginView guidance once

Add explicit validation checkpoints after Step 2 (verify services resolve), Step 4 (verify migration applied and tables exist), and Step 5 (verify login flow works end-to-end before proceeding to authorization migration)

Reduce the overall document to under 150 lines by keeping Steps 1-7 as concise instructions with code, and deferring all extended examples and edge cases to the companion document

DimensionReasoningScore

Conciseness

The skill is extremely verbose at ~350+ lines. It repeats the same concepts multiple times (e.g., DisableAntiforgery is explained in Critical Rules, the endpoint pattern, the endpoint templates section, AND a dedicated section; LoginView vs AuthorizeView is stated in Critical Rules, the migration example, AND a warning box). The BWFC login controls table appears twice. Much content that should be in the companion IDENTITY-PATTERNS.md is inlined here.

1 / 3

Actionability

The skill provides fully executable, copy-paste ready code throughout — complete C# endpoint handlers, Blazor component markup, bash commands for package installation and migrations, and specific configuration code for Program.cs. Every step has concrete, runnable examples.

3 / 3

Workflow Clarity

Steps 1-7 provide a clear sequence for the migration process, but there are no explicit validation checkpoints between steps. For a migration involving database schema changes and authentication (a destructive/risky operation), there should be verification steps after the database migration (Step 4) and after configuring identity (Step 2) to confirm the setup works before proceeding.

2 / 3

Progressive Disclosure

Despite referencing a companion IDENTITY-PATTERNS.md document, the skill inlines nearly all the content that document should contain — cookie auth details, endpoint templates, OWIN mapping table, gotchas, and authorization patterns are all present in the main file. The companion document table suggests content splitting but the skill doesn't actually practice it, resulting in a monolithic document.

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 hits all the key criteria. It provides specific concrete actions, natural trigger terms, explicit 'when' guidance, and clear boundary delineation from related skills. The description is concise yet comprehensive, using proper third-person voice throughout.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: migrate OWIN→Core middleware, login/register/logout minimal API endpoints, BWFC login controls, cookie auth under Interactive Server, and role-based authorization. Very detailed and actionable.

3 / 3

Completeness

Clearly answers both 'what' (migrate ASP.NET Web Forms Identity to Blazor Server Identity with specific sub-tasks) and 'when' (explicit WHEN clause with trigger phrases). Also includes boundary guidance via 'FOR SINGLE OPERATIONS' directing to other skills.

3 / 3

Trigger Term Quality

Includes natural trigger terms users would say: 'migrate identity', 'login page migration', 'OWIN to core', 'cookie auth blazor', 'LoginView migration'. These cover realistic user phrasings and domain-specific terms well.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive niche: ASP.NET Web Forms Identity to Blazor Server Identity migration. Explicitly differentiates from related skills (bwfc-migration for markup, bwfc-data-migration for EF), reducing conflict risk significantly.
