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 5.1 | $0.00087 | $0.00646 |
| Opus 5 | $0.00044 | $0.00323 |
| Sonnet 5 | $0.00017 | $0.00129 |
| Haiku 4.5 | $0.00009 | $0.00065 |
Grade A, and why
dynt-subscription-audit 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
FIRST: read the parent dynt skill for connection, safety rules and tool families.
Subscription audit
Outcome: a ranked list of subscriptions with monthly cost, trend and a recommendation per item — and, only on request, the recurring flags saved.
1. Detect (read-only)
If the server offers list_findings, call it first: price increases, stopped subscriptions, duplicate charges and missing-receipt clusters arrive pre-computed with evidence and money at stake — do not recompute them; use the steps below for what findings do not cover.
list_subscriptions with monthsBack (default 6; use 12 for yearly plans)
and minOccurrences: 2. This never modifies data.
For each result keep: merchant, cadence, average amount, last amount, charge history, estimated monthly spend. Compute:
- Price increase: last amount > average by more than 5% → flag with the two amounts and dates.
- Possibly unused: no charge in the last cadence period + 7 days → flag.
- Duplicates: two merchants that normalize to the same provider.
2. Enrich
For each flagged merchant, lookup_provider → free tier, pricing URL, cancel
URL, alternatives. Unknown provider → say so; do not invent pricing.
Optional evidence (admin with email:read): search_user_email for the
merchant name with includeBody=false to find plan/renewal emails; quote
subject and date only.
3. Present
Table ordered by estimated monthly spend, then a short recommendation per row: keep / downgrade (to what) / cancel (link) / switch (alternative). Total monthly and yearly figures at the bottom, in the organization's currency.
4. Persist flags (write — confirm first)
Only if the user asks to mark subscriptions on their transactions:
flag_recurring_transactions with the same monthsBack / minOccurrences.
Only monthly and yearly detections are persisted; irregular ones are returned but not flagged — say so in the report. Manual user flags are never overwritten. Requires write.
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.

dynt-subscription-audit is a skill published in the GitHub repository bpais88/dynt-agent-skills (0 stars, last pushed 11d ago), licensed MIT. It adds 87 tokens to every session and 646 once invoked, about $0.0004 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 2026-08-31.
