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 | $0.09707 | $0.09707 |
| Opus 5 | $0.04854 | $0.04854 |
| Sonnet 5 | $0.01941 | $0.01941 |
| Haiku 4.5 | $0.00971 | $0.00971 |
Grade A, and why
ecowitt_local CLAUDE.md scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
This is a Home Assistant custom integration for Ecowitt weather stations that uses local web interface polling instead of webhooks. The integration creates stable entity IDs based on hardware IDs and organizes sensors into individual devices for better management.
⚠️ CRITICAL: Entity Creation Pipeline Issues
IMPORTANT: This codebase has ongoing entity creation failures despite proper device detection. The primary issues are incomplete entity sets and mapping pipeline failures, not architectural violations. Focus on debugging the entity creation flow rather than mapping logic.
Development Commands
Local environment
The project uses a virtualenv at .venv/ in the project root.
- Python: Homebrew Python 3.14 at
/opt/homebrew/bin/python3 - Create venv:
python3 -m venv .venv && .venv/bin/pip install -r requirements_test.txt
Testing
# Run all tests with coverage (ALWAYS use .venv, not system python)
PYTHONPATH="$PWD" .venv/bin/pytest tests/ -v
# Run with coverage report
PYTHONPATH="$PWD" .venv/bin/pytest tests/ --cov=custom_components/ecowitt_local --cov-report=term-missing
Coverage must be 100%. If coverage drops, add tests before committing.
⚠️ Mandatory pre-commit checklist
Run ALL of these before every commit. CI will fail if any step is skipped.
# 1. Format
black custom_components/ecowitt_local/ tests/
# 2. Sort imports
isort custom_components/ecowitt_local/ tests/
# 3. Type check (must show "Success: no issues found")
mypy custom_components/ecowitt_local/ --follow-imports=silent --ignore-missing-imports
# 4. Full test suite with coverage (must be 100%)
PYTHONPATH="$PWD" .venv/bin/pytest tests/ --cov=custom_components/ecowitt_local --cov-report=term-missing
Development Dependencies
Install test requirements: pip install -r requirements_test.txt
Architecture Overview
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.

ecowitt_local CLAUDE.md is an instructions file published in the GitHub repository alexlenk/ecowitt_local (59 stars, last pushed today), licensed MIT. It adds 9,707 tokens to every session, about $0.0485 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
