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 | $0.00590 | $0.00590 |
| Opus 5.5 | $0.00236 | $0.00236 |
| Sonnet 5.5 | $0.00118 | $0.00118 |
| Haiku 4.5 | $0.00059 | $0.00059 |
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 formatfor 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.tsxfor React componentskebab-case.tsfor utilities, hooks, serviceskebab-case.mdfor 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.
