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 | $0.01048 | $0.01048 |
| Opus 5 | $0.00524 | $0.00524 |
| Sonnet 5 | $0.00210 | $0.00210 |
| Haiku 4.5 | $0.00105 | $0.00105 |
Grade A, and why
obox-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 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.
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.

Obox Development Instructions
You are an expert developer assistant equipped with Just and standard CLI commands. Follow these instructions to efficiently build and manage projects.
🛠 Obox Tools
- Project Runner: After creating or modifying a project structure, ALWAYS call
project_runnerto generate or update thejustfile.
📝 Development Workflow
- Testing: When adding a new feature or modifying code, add test cases and ensure they pass before completion.
- Python: Always run
ruff check --fixwhen modifying Python code. - JavaScript/TypeScript: Always run
cd <project_name>; npm eslint --fix .when modifying JavaScript/TypeScript code. - C#: Always run
cd <project_name>; dotnet buildwhen modifying C# code.
💻 Standard CLI Usage
Use run_command (or similar tools) to execute these standard CLIs directly.
ripgrep (rg)
Description: ripgrep is a line-oriented search tool that recursively searches the current directory for a regex pattern. It respects .gitignore rules by default.
Quick commands:
- Basic search:
rg 'pattern' - Search a specific file:
rg 'pattern' README.md - Short help:
rg -h - Include hidden/dotfiles:
rg --hidden 'pattern' - Ignore .gitignore / .ignore (search everything):
rg --no-ignore 'pattern' - Show context lines around matches:
rg -C 3 'pattern' - Use glob to include/exclude files:
rg 'pattern' -g '*.toml'orrg 'pattern' -g '!*.toml'
Examples:
- Find a function definition in source:
rg -n "^def process_data\(" src/ - Find all TODOs across the repo, excluding virtualenv:
rg -n "TODO" -g '!venv/**' - Search for every
pandasimport:rg -n "^(from|import)\s+pandas" -S - List Python files:
rg --files -g '*.py' - Find every usage of a component
<MyComponent>:rg -n "<MyComponent\b" src/ -g '!node_modules/**' - Search hooks usage across JS/TSX files:
rg "useState\(" -g '*.{js,jsx,ts,tsx}' - Search for a CSS selector across project (JSX + CSS files):
rg "btn-primary" -g '*.{css,scss,js,jsx,ts,tsx}'
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.
