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 | $0.00957 | $0.00957 |
| Opus 5.5 | $0.00383 | $0.00383 |
| Sonnet 5.5 | $0.00191 | $0.00191 |
| Haiku 4.5 | $0.00096 | $0.00096 |
Grade A, and why
zaim-csv-converter CLAUDE.md 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 20d 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.

Project Overview
This is Zaim CSV Converter, a Python tool that converts CSV files from various financial accounts (credit cards, banks, e-money cards) into Zaim's import format. It supports multiple account types including WAON, MUFG Bank, Amazon.co.jp, PayPal, and others.

Architecture
Core Structure
- Entry point:
convert.py- Simple wrapper callingZaimCsvConverter.execute() - Main package:
zaimcsvconverter/- Core conversion logic - Configuration:
config.yml(copy fromconfig.yml.dist) - Input/Output directories:
csvinput/andcsvoutput/ - Conversion tables:
csvconverttable/- Store and item mapping definitions
Key Components
Data Flow Architecture
- Data Sources (
inputtooutput/datasources/): CSV file readers and parsers for each account type - Converters (
inputtooutput/converters/recordtozaim/): Transform account-specific records to Zaim format - Exporters (
inputtooutput/exporters/zaim/): Output Zaim-compatible CSV files - Error Handling (
errorhandling/,errorreporters/): Validation and error reporting
Account Support Pattern
Each supported account follows a consistent pattern with:
- Data model (
data/[account].py): Pydantic models for CSV structure - Record processor (
records/[account].py): Raw CSV to structured data - Converter (
converters/recordtozaim/[account].py): Business logic for Zaim conversion - CSV converter (
datasources/csvfile/converters/[account].py): File processing
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.
