Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00298 |
| Opus 5 | $0.00000 | $0.00149 |
| Sonnet 5 | $0.00000 | $0.00060 |
| Haiku 4.5 | $0.00000 | $0.00030 |
Grade A, and why
dir.code-style scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Python Style
- Use Black for formatting (line length: 100)
- Use type hints for all function parameters and return types
- Follow PEP 8 conventions
- Use docstrings for all public functions and classes
Example:
def calculate_total(items: List[Item]) -> Decimal:
"""Calculate total price including tax.
Args:
items: List of items to calculate
Returns:
Total price with tax applied
"""
subtotal = sum(item.price for item in items)
return subtotal * Decimal("1.08")
TypeScript Style
- Use Prettier for formatting
- Enable strict mode in tsconfig.json
- Prefer const over let
- Use explicit types (avoid 'any')
- Use interfaces for object shapes
Example:
interface UserProfile {
id: string;
name: string;
email: string;
createdAt: Date;
}
const fetchUserProfile = async (userId: string): Promise<UserProfile> => {
const response = await api.get(`/users/${userId}`);
return response.data;
};
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.

dir.code-style is a cursor rule published in the GitHub repository henriquemoody/charlie (6 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 298 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
