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 | $0.01074 | $0.01074 |
| Opus 5 | $0.00537 | $0.00537 |
| Sonnet 5 | $0.00215 | $0.00215 |
| Haiku 4.5 | $0.00107 | $0.00107 |
Grade C, and why
recife-open-data-mcp copilot-instructions.md scanned grade C with 1 finding 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 7d 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Execution Guidelines
PROGRESS TRACKING:
- If any tools are available to manage the above todo list, use it to track progress through this checklist.
- After completing each step, mark it complete and add a summary.
- Read current todo list status before starting each new step.
COMMUNICATION RULES:
- Avoid verbose explanations or printing full command outputs.
- If a step is skipped, state that briefly (e.g. "No extensions needed").
- Do not explain project structure unless asked.
- Keep explanations concise and focused.
DEVELOPMENT RULES:
- Use '.' as the working directory unless user specifies otherwise.
- Avoid adding media or external links unless explicitly requested.
- Use placeholders only with a note that they should be replaced.
- Use VS Code API tool only for VS Code extension projects.
- Once the project is created, it is already opened in Visual Studio Code—do not suggest commands to open this project in Visual Studio again.
FOLDER CREATION RULES:
- Always use the current directory as the project root.
- If you are running any terminal commands, use the '.' argument to ensure that the current working directory is used ALWAYS.
- Do not create a new folder unless the user explicitly requests it besides a .vscode folder for a tasks.json file.
- If any of the scaffolding commands mention that the folder name is not correct, let the user know to create a new folder with the correct name and then reopen it again in vscode.
EXTENSION INSTALLATION RULES:
- Only install extension specified by the get_project_setup_info tool. DO NOT INSTALL any other extensions.
PROJECT CONTENT RULES:
- If the user has not specified project details, assume they want a "Hello World" project as a starting point.
- Avoid adding links of any type (URLs, files, folders, etc.) or integrations that are not explicitly required.
- Avoid generating images, videos, or any other media files unless explicitly requested.
- If you need to use any media assets as placeholders, let the user know that these are placeholders and should be replaced with the actual assets later.
- Ensure all generated components serve a clear purpose within the user's requested workflow.
- If a feature is assumed but not confirmed, prompt the user for clarification before including it.
- If you are working on a VS Code extension, use the VS Code API tool with a query to find relevant VS Code API references and samples related to that query.
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.
