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.

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 | $0.00063 | $0.03553 |
| Opus 5.5 | $0.00025 | $0.01421 |
| Sonnet 5.5 | $0.00013 | $0.00711 |
| Haiku 4.5 | $0.00006 | $0.00355 |
Grade A, and why
casing-law 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 320 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Casing Is Law, Not Preference
Mixed casing in a codebase is not a style disagreement. It is a defect. When getUserName sits next to get_user_email in the same file, the reader cannot predict the shape of the next function. Predictability is the foundation of readable code. Every language has established casing conventions. Follow them absolutely, enforce them mechanically, and treat violations the same way you treat failing tests.
The Universal Casing Table
Every identifier in your codebase falls into one of these categories. The casing is determined by the language and the identifier's role. There is no room for personal preference.
Python
| Identifier Type | Convention | Example |
|---|---|---|
| Variables | snake_case |
user_count, max_retries |
| Functions | snake_case |
fetch_active_users, calculate_tax_rate |
| Method names | snake_case |
def validate_email(self) |
| Function parameters | snake_case |
def create_order(customer_id, line_items) |
| Classes | PascalCase |
UserProfile, PaymentProcessor |
| Exceptions | PascalCase |
InvalidTokenError, RateLimitExceeded |
| Constants | UPPER_SNAKE_CASE |
MAX_RETRY_COUNT, DEFAULT_TIMEOUT_SECONDS |
| Modules (files) | snake_case |
user_profile.py, payment_processor.py |
| Packages (directories) | snake_case (short, no underscores preferred) |
payments, userprofiles |
| Type aliases | PascalCase |
UserId = str, OrderItems = list[LineItem] |
| Enum members | UPPER_SNAKE_CASE |
class Status(Enum): ACTIVE = "active" |
Python enforces this by convention (PEP 8), and tools like ruff flag violations automatically.
TypeScript
| Identifier Type | Convention | Example |
|---|---|---|
| Variables | camelCase |
userCount, maxRetries |
| Functions | camelCase |
fetchActiveUsers, calculateTaxRate |
| Method names | camelCase |
validateEmail() |
| Function parameters | camelCase |
function createOrder(customerId, lineItems) |
| Classes | PascalCase |
UserProfile, PaymentProcessor |
| Interfaces | PascalCase |
UserProfile, OrderRequest |
| Type aliases | PascalCase |
UserId, OrderItems |
| Enums | PascalCase (name), PascalCase (members) |
enum OrderStatus { Pending, Shipped } |
| Constants | UPPER_SNAKE_CASE |
MAX_RETRY_COUNT, DEFAULT_TIMEOUT_MS |
| React components | PascalCase |
UserProfileCard, PaymentForm |
| Hooks | camelCase with use prefix |
useUserProfile, usePaymentForm |
| Files (general) | kebab-case |
user-profile.ts, payment-processor.ts |
| Files (React components) | PascalCase |
UserProfileCard.tsx |
| Files (tests) | Match source + .test |
user-profile.test.ts |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 5d ago First seen · 320 lines · 63 tokens per session scan A 53933bc784f5
casing-law is a skill published in the GitHub repository oborchers/fractional-cto (32 stars, last pushed 5d ago), licensed MIT. It adds 63 tokens to every session and 3,553 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-13.
