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.

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 | $0.00119 | $0.01975 |
| Opus 5.5 | $0.00048 | $0.00790 |
| Sonnet 5.5 | $0.00024 | $0.00395 |
| Haiku 4.5 | $0.00012 | $0.00198 |
Grade A, and why
blazor 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 24d 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.

Blazor
Trigger On
- building interactive web UIs with C# instead of JavaScript
- choosing between Server, WebAssembly, or Auto render modes
- designing component hierarchies and state management
- handling prerendering and hydration
- integrating with JavaScript when necessary
- connecting Blazor UI with AI backends and building AI agents with .NET

Render Modes (.NET 8+)
| Mode | Where It Runs | Best For |
|---|---|---|
Static |
Server (no interactivity) | SEO pages, marketing content |
InteractiveServer |
Server via SignalR | Real-time apps, thin clients |
InteractiveWebAssembly |
Browser via WASM | Offline-capable, client-heavy |
InteractiveAuto |
Server first, then WASM | Best of both worlds |

What ships with it
3 files 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.

blazor is a skill published in the GitHub repository managedcode/dotnet-skills (489 stars, last pushed today), licensed MIT. It adds 119 tokens to every session and 1,975 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.

maf-migration-retrospective
Post-migration learning skill. After a migration completes, reads the migration plan notes, build history, and surprises to improve the registry, guide, and constraint rules. Invoked as the final step of any migration. This is how the toolkit gets smarter with each use.
maf-migration-plan-creator
Generates a complete, ready-to-execute MAF migration plan (migration-plan.md) for any .NET codebase. Used by @maf-auditor (which calls this skill after scanning to produce the plan). Use this skill directly when no migration plan exists yet, or when the existing plan needs to be regenerated after a codebase audit.…
