Skill: cost-estimator

Estimates Make.com operation counts and monetary costs for automation plans. Also tracks actual usage against plan limits.

Operation Count Formula

Make.com charges one operation per module execution.

operations_per_run = number of modules that execute per scenario run
                     (count active modules, not error-path modules)

monthly_operations = operations_per_run × estimated_runs_per_month

Execution Frequency Estimates

Trigger type	Estimated runs/month
Manual only	10-50
Schedule: once/day	30
Schedule: 4x/day	120
Schedule: hourly	720
Schedule: 15-minute	2,880
Webhook: low volume (<10/day)	300
Webhook: medium volume (10-100/day)	3,000
Webhook: high volume (>100/day)	30,000+
Watch trigger: polling	estimate based on poll interval

Ask user for expected volume when trigger is webhook or watch and they haven't specified.

Output Format

Include in every AutomationPlan:

## Cost Estimate

### Make.com Operations
| Item | Count |
|------|-------|
| Modules per run | {n} |
| Estimated runs/month | {n} |
| **Total operations/month** | **{n}** |

### Monthly Cost Breakdown
| Item | Cost |
|------|------|
| Make.com operations | ${estimate} |
| OpenAI API (if used) | ${estimate} |
| Other APIs | ${estimate} |
| **Total estimated/month** | **${total}** |

### Plan Usage Impact
| | Before | After |
|-|--------|-------|
| Operations used | {current} | {current + new} |
| Plan limit | {limit} | {limit} |
| Usage % | {before%} | {after%} |

{Warning if after% > 80%: "This automation will push your monthly usage to X%. 
Consider upgrading your plan or reducing polling frequency."}

Usage Tracking

Read from .make/workspace.json:

• monthly_operation_limit
• operations_used_this_month

Update operations_used_this_month after each execution log is written.

Thresholds:

• 80% used → show warning in every plan and status check

• 95% used → show critical warning, recommend pausing low-priority scenarios

• 100% used → Make.com will pause scenarios. Alert user immediately.
