Monthly Closer

Monthly Closer

Generate structured monthly closing reports for client companies. Produces a Markdown summary with transaction statistics, category breakdowns, and anomaly detection.

When to use

Invoke this skill when:

• End of month arrives and the tax accountant needs a closing summary
• A client requests a monthly financial overview
• The firm needs to review classification quality for the period

Report structure

The generate_monthly_report tool produces a report with these sections:

1. Summary header

• Company name, reporting period (year/month)
• Generation timestamp
• Data source (freee / Yayoi / MF / imported CSV)

2. Transaction statistics

• Total transaction count
• Total expenditure (支出合計)
• Total revenue (収入合計)
• Classification breakdown: auto-classified vs. manually reviewed
• Memory hit rate for the period

3. Category breakdown (勘定科目別集計)

Table showing each category with:

勘定科目	件数	金額	構成比
旅費交通費	45	¥234,500	18.2%
会議費	32	¥128,000	9.9%
...	...	...	...

4. Month-over-month anomaly detection

Compares each category against the previous month. Flags any category where the amount changed by plus or minus 50% or more.

Example flags:

• "広告宣伝費: ¥580,000 (前月比 +210%) — 要確認"
• "外注費: ¥45,000 (前月比 -65%) — 要確認"

Anomalies are not errors — they are prompts for the tax accountant to verify that large swings are expected.

5. Classification quality metrics

• Stage 0 exclusion count
• Stage 1 keyword/memory hit count
• Stage 2 AI classification count
• Items requiring manual review (low confidence)

Output format

Reports are generated as Markdown by default. The output can be:

• Displayed directly in the terminal
• Saved to a file for archival
• Shared with clients via email or converted to PDF
