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 | $0.00028 | $0.01248 |
| Opus 5 | $0.00014 | $0.00624 |
| Sonnet 5 | $0.00006 | $0.00250 |
| Haiku 4.5 | $0.00003 | $0.00125 |
Grade A, and why
python-skills 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.

Code Style
LlamaFarm uses ruff with shared configuration in ruff.toml:
line-length = 88
target-version = "py311"
select = ["E", "F", "I", "B", "UP", "SIM"]
Key rules:
- E, F: Core pyflakes and pycodestyle
- I: Import sorting (isort)
- B: Bugbear (common pitfalls)
- UP: Upgrade syntax to modern Python
- SIM: Simplify code patterns
Architecture Patterns
Settings with pydantic-settings
from pydantic_settings import BaseSettings
class Settings(BaseSettings, env_file=".env"):
LOG_LEVEL: str = "INFO"
HOST: str = "0.0.0.0"
PORT: int = 14345
settings = Settings() # Singleton at module level
Structured Logging with structlog
from core.logging import FastAPIStructLogger # Server
from core.logging import RAGStructLogger # RAG
from core.logging import UniversalRuntimeLogger # Runtime
logger = FastAPIStructLogger(__name__)
logger.info("Operation completed", extra={"count": 10, "duration_ms": 150})
What ships with it
6 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.

python-skills is a skill published in the GitHub repository llama-farm/llamafarm (837 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 28 tokens to every session and 1,248 once invoked, about $0.0001 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 2026-08-30.
