Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Prompt Injection · line 149 Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00122 | $0.04421 |
| Opus 5.5 | $0.00049 | $0.01768 |
| Sonnet 5.5 | $0.00024 | $0.00884 |
| Haiku 4.5 | $0.00012 | $0.00442 |
Grade A, and why
bwfc-identity-migration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Web Forms Identity → Blazor Identity Migration
Overview
| Web Forms Auth System | Era | Blazor Migration Path |
|---|---|---|
| ASP.NET Identity (OWIN) | 2013+ | ASP.NET Core Identity (closest match) |
| ASP.NET Membership | 2005-2013 | Core Identity (schema migration required) |
| FormsAuthentication | 2002-2005 | Core Identity or cookie auth |
Related: /bwfc-migration (markup), /bwfc-data-migration (EF/architecture)
Critical Rules
- Cookie auth requires HTTP endpoints — login/register/logout MUST use
<form method="post">+ minimal API endpoints. Component event handlers (@onclick) silently fail for cookie operations in interactive mode. - NEVER replace LoginView with AuthorizeView — BWFC
LoginViewusesAuthenticationStateProvidernatively with same template names (AnonymousTemplate,LoggedInTemplate). - DisableAntiforgery required — Blazor forms don't include antiforgery tokens. All auth endpoints must call
.DisableAntiforgery(). - Session-based auth data works —
Session["key"]viaWebFormsPageBase.Session/SessionShim. Don't injectIHttpContextAccessor.
Quick Reference
BWFC Login Controls (drop-in replacements)
<Login />, <LoginName />, <LoginStatus />, <LoginView>, <CreateUserWizard />, <ChangePassword />, <PasswordRecovery />
Auth Endpoint Pattern
// Program.cs — login via HTTP POST (required for cookie auth)
app.MapPost("/Account/LoginHandler", async (HttpContext ctx, SignInManager<IdentityUser> sm) =>
{
var form = await ctx.Request.ReadFormAsync();
var result = await sm.PasswordSignInAsync(form["email"]!, form["password"]!, false, false);
return result.Succeeded ? Results.Redirect("/") : Results.Redirect("/Account/Login?error=failed");
}).DisableAntiforgery();

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

bwfc-identity-migration is a skill published in the GitHub repository FritzAndFriends/BlazorWebFormsComponents (455 stars, last pushed 4mo ago), licensed MIT. It adds 122 tokens to every session and 4,421 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
