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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00094 | $0.00667 |
| Opus 5 | $0.00047 | $0.00333 |
| Sonnet 5 | $0.00019 | $0.00133 |
| Haiku 4.5 | $0.00009 | $0.00067 |
Grade A, and why
dynt-month-end-summary 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 12d 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.
What it actually says
FIRST: read the parent dynt skill for connection, safety rules and tool families.
Month-end summary
Outcome: one briefing with numbers the user can trust, each traceable to a tool call. Read-only — this skill never writes.
Period
Default to the previous full calendar month unless the user names a period.
State the exact startDate–endDate you used at the top.
Collect (parallel where the client allows)
get_transaction_summary(startDate, endDate) → count, needs-review count, income, expenses. These are the headline numbers.list_merchants→ top 10 by spend in the period (filter to the period if the tool supports it; otherwise say "all-time").list_invoices→ unpaid and overdue outgoing invoices: customer, amount, due date, days overdue. Paginate fully.list_bills→ unpaid and overdue supplier bills, same fields.list_expenses→ pending employee expense claims: submitter, amount, age.get_anomaly_summary→ open anomalies count (details are indynt-anomaly-triage).list_accounts→ balances per account and currency.

Then 3–5 bullet "actions this week", each pointing to a workflow skill (receipts, cleanup, subscriptions, anomalies).
Gotchas
- Do not add signed transaction amounts yourself; use the summary tool.
- Multi-currency accounts: report per currency; do not convert unless asked, and then say which rate you assumed.
- "Needs review" is a count of transactions awaiting accounting status, not errors.
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.
