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 | $0.00069 | $0.02411 |
| Opus 5 | $0.00034 | $0.01205 |
| Sonnet 5 | $0.00014 | $0.00482 |
| Haiku 4.5 | $0.00007 | $0.00241 |
Grade A, and why
pep8 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 8d 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.

Python Style & PEP 8 Enforcement
Auto-enforce Python 3.11+ standards.
When to Use
- Writing/reviewing Python code
- Type hint issues or style violations
- User requests PEP 8 check
Core Standards
| Standard | Desc |
|---|---|
| PEP 8 | Naming, imports, spacing |
| PEP 484/585 | Type hints (modern) |
| PEP 257 | Docstrings |
| PEP 604 | Union | |
| PEP 570/3102 | / positional, * keyword |
Naming
class UserAccount: pass # PascalCase
class HTTPClient: pass # Acronyms: all caps
def calculate_total(): pass # snake_case
async def fetch_data(): pass # async same
user_name = "john" # Variables: snake_case
MAX_RETRIES = 3 # Constants: SCREAMING_SNAKE
def _internal(): pass # Private: underscore
__mangled = "hidden" # Name mangling: double
T = TypeVar("T") # TypeVars: PascalCase
UserT = TypeVar("UserT", bound="User")
Type Hints (3.11+)
Modern Syntax (Required)
# Built-in generics (NOT typing module)
def process(items: list[str]) -> dict[str, int]: ...
# Union w/ | (NOT Optional/Union)
def find_user(id: str) -> User | None: ...
# Self type
from typing import Self
class Builder:
def chain(self) -> Self: return self
Patterns
from collections.abc import Callable, Awaitable
from typing import TypedDict, Literal, TypeAlias, ParamSpec, Generic
# Callable
Handler = Callable[[Request], Response]
AsyncHandler = Callable[[Request], Awaitable[Response]]
# TypedDict
class UserData(TypedDict):
id: str
email: Required[str]
phone: NotRequired[str | None]
# Literal
Status = Literal["pending", "active", "disabled"]
# TypeAlias
JsonValue: TypeAlias = str | int | float | bool | None | list["JsonValue"] | dict[str, "JsonValue"]
# ParamSpec (decorators)
P = ParamSpec("P")
def logged(fn: Callable[P, T]) -> Callable[P, T]: ...
# Generic
class Repo(Generic[T]):
def get(self, id: str) -> T | None: ...
What ships with it
4 files 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.

pep8 is a skill published in the GitHub repository hackermanishackerman/claude-skills-vault (2 stars, last pushed yesterday), licensed MIT. It adds 69 tokens to every session and 2,411 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
