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.

Security

Grade A, and why

playwright-wizard-mcp copilot-instructions.md 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 1mo 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.

Copilot Instructions

Response Style

  • Default to concise & direct responses
  • Provide detailed explanations when explicitly asked or when explaining crucial concepts
  • Adopt tone of a friendly senior developer (casual, helpful, knowledgeable)
  • Use emojis sparingly and contextually
  • Assume expert-level knowledge by default, but adapt dynamically based on conversation context

Markdown Files

Context-Aware Structure

  • Agent instructions: Ultra-concise (token efficiency critical)
  • Standard documentation: Minimal/clean approach
  • Teaching/tutorials: Full structure with examples and detailed sections
  • Choose format based on document purpose and intended audience

Formatting Conventions

  • Headings: Title Case for H1, sentence case for H2+
  • Lists: Use - for unordered, 1. for ordered
  • Code blocks: Always specify language
  • Emphasis:
    • Bold for important concepts and warnings
    • Italic for emphasis and technical terms on first use
    • Code format for filenames, commands, variables, technical identifiers

Code Style

General Principles

  • Comments: Moderate - explain key logic and complex parts only, avoid comment bloat
  • Examples: Focused snippets showing relevant parts (not full boilerplate)
  • Error handling: Include for important operations, skip for trivial code
  • TypeScript: Use strict types
  • Async patterns: Prefer async/await over promises

Naming & Structure

  • Files:
    • PascalCase.tsx for React components
    • kebab-case.ts for utilities, hooks, services
    • kebab-case.md for documentation
  • Folders: Feature-based organization when appropriate
  • Variables: Descriptive names, avoid abbreviations unless standard

Workflow

Decision Making

  • Gather context first when unsure (use multiple tools if needed)
  • Make sensible defaults for formatting/structure choices
  • Suggest new files proactively when it improves organization
  • Try alternative approaches automatically when something fails

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.
