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 | $0.00013 | $0.02408 |
| Opus 5 | $0.00006 | $0.01204 |
| Sonnet 5 | $0.00003 | $0.00482 |
| Haiku 4.5 | $0.00001 | $0.00241 |
Grade A, and why
roi-calculator 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

AI Automation ROI Calculator
Get a concrete dollars-and-cents estimate of what AI automation would save your business. No fluff, no inflated projections -- just math you can take to your team, your partner, or your bank account.
Usage
Provide the following:
Required Inputs
| Field | Example | Notes |
|---|---|---|
| Industry | "Digital marketing agency" | Helps benchmark against similar businesses |
| Team Size | 8 | Total people (including you) |
| Manual Hours per Week | 35 | Total hours your team spends on repetitive tasks |
| Average Hourly Cost | $45 | Loaded cost (salary + benefits + overhead / hours) |
Optional Inputs (improve accuracy)
| Field | Example | Notes |
|---|---|---|
| Annual Revenue | $1.2M | Used for revenue-impact calculations |
| Top 3 Time Sinks | "Reporting, client emails, invoice creation" | Get specific automation estimates |
| Current Tool Spend | $2,400/month | Factor in tools that automation might replace |
| Growth Target | "Double revenue without adding headcount" | Changes the framing of ROI |
| Error/Rework Rate | "~10% of deliverables need rework" | Hidden cost most businesses ignore |
Calculation Engine
Step 1: Baseline Cost Analysis
CURRENT STATE:
Manual hours/week: [X] hours
Team members involved: [X] people
Avg hourly cost (loaded): $[X]/hour
Weekly cost of manual work: $[hours x cost]
Annual cost of manual work: $[weekly x 50 weeks]
Loaded hourly cost guide (if they don't know):
- For employees: (Annual salary x 1.3) / 2,080 hours
- The 1.3 multiplier accounts for benefits, taxes, office costs
- For the business owner: Use your target hourly rate, or revenue / hours worked
- For contractors: Their rate is already loaded
Step 2: Automation Savings Estimate
Not all manual hours can be automated. Apply realistic automation rates by task type:
| Task Category | Automation Rate | Examples |
|---|---|---|
| Data entry & transfer | 85-95% | CRM updates, spreadsheet population, cross-system data sync |
| Report generation | 75-90% | Weekly reports, dashboards, client updates |
| Email & communication | 50-70% | Follow-ups, templates, meeting scheduling, auto-responses |
| Content creation | 40-60% | Social posts, email drafts, basic copywriting |
| Client onboarding | 60-80% | Welcome sequences, form processing, account setup |
| Invoicing & billing | 80-95% | Invoice creation, payment reminders, expense tracking |
| Scheduling & coordination | 70-85% | Calendar management, resource allocation, task assignment |
| Quality assurance | 30-50% | Review checklists, error detection, compliance checks |
| Research & analysis | 40-60% | Market research, competitor monitoring, data analysis |
| Customer support | 40-65% | FAQ responses, ticket routing, status updates |
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.

roi-calculator is a skill published in the GitHub repository koinod/koino-skills (8 stars, last pushed 3mo ago), licensed MIT. It adds 13 tokens to every session and 2,408 once invoked, about $0.0001 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.
