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 | $0.00012 | $0.01851 |
| Opus 5 | $0.00006 | $0.00925 |
| Sonnet 5 | $0.00002 | $0.00370 |
| Haiku 4.5 | $0.00001 | $0.00185 |
Grade A, and why
negotiate 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 5d 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 — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/smartspender:negotiate
Trigger
/smartspender:negotiate [service]- "Forhandl prisen paa Netflix"
- "Negotiate my TDC subscription"
- "Kan jeg faa en bedre pris paa Fitness World?"
- "Skriv en forhandlingsmail til TDC"
Arguments
| Argument | Required | Values | Default |
|---|---|---|---|
| service | yes | Service name matching a merchant in subscriptions.csv | - |
The service argument is case-insensitive and matched against the merchant column in subscriptions.csv (e.g., tdc, netflix, fitness-world).
Prerequisites
- Subscription detected in subscriptions.csv
- Transaction history in categorized.csv (for cost analysis)
- Negotiation skill loaded:
skills/negotiation/SKILL.md
Workflow
- Normalize the service argument to lowercase, replace spaces with hyphens
- Look up the service in subscriptions.csv by matching
merchantname (case-insensitive) - If not found: "Abonnementet '{service}' blev ikke fundet i dine abonnementer. Koer /smartspender:subscriptions for at se dine aktive abonnementer."
- If already cancelled: "Abonnementet '{service}' er allerede opsagt ({cancelled_date}). Der er ikke noget at forhandle."
- Read the subscription record:
merchant,amount,frequency,annual_cost,first_seen,last_seen,status
Cost Analysis
- Read categorized.csv, filter by merchant name (case-insensitive match)
- Calculate:
monthly_cost: current subscription amount from subscriptions.csvannual_cost: from subscriptions.csvtotal_paid: sum of all matching transactions in categorized.csvmonths_as_customer: number of months betweenfirst_seenand today
- If receipts exist for this merchant in receipts.csv, read receipt-items from the relevant
receipt-items-{YYYY-MM}.csvfiles. Note any unused services or add-ons visible in line items. - If no transaction history found: "Ingen transaktionshistorik fundet for '{service}'. Koer /smartspender:sync foerst."

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.
