Token cost

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	$0.02059	$0.02059
Opus 5.5	$0.00824	$0.00824
Sonnet 5.5	$0.00412	$0.00412

Security

Grade C, and why

blake copilot-instructions.md scanned grade C with 2 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 11d 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.

Blake - Copilot Instructions

Blake is a Blazor-based static site generator that embraces Occam's Razor and convention-over-configuration principles. It allows developers to create static websites using familiar .NET technologies: Markdown files, Razor templates, and Blazor components.

Development Guidelines

Always search Microsoft documentation (MS Learn) when working with .NET, Windows, or Microsoft features, or APIs. Use the microsoft_docs_search tool to find the most current information about capabilities, best practices, and implementation patterns before making changes.

Project Philosophy

Blake is guided by simplicity and minimalism:

Minimal assumptions: Use familiar .NET and Blazor patterns
Convention-over-configuration: Folder structure determines behavior
Transparency: Developers should understand their build process
Familiarity: Leverage existing .NET/Blazor knowledge

Core Principle: "Bake your Blazor into beautiful static sites" with the fewest assumptions and maximum developer control.

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.
