工具（9）
🟢get_pricing(slug, depth)
Full sourced pricing record for a software product: tiers, hidden costs, contract terms, market data, sentiment, negotiation tips, TCO scenarios, price history — every claim with its sources + a confidence/verification envelope.
輸入結構描述
{
"type": "object",
"properties": {
"slug": {
"type": "string",
"description": "Product slug, e.g. \"salesforce\""
},
"depth": {
"type": "string",
"enum": [
"summary",
"full"
],
"description": "summary = numbers+sources only"
}
},
"required": [
"slug"
]
}🟢get_hidden_costs(slug)
The documented hidden/implementation/add-on costs of a product (uplifts, onboarding fees, overages), each with a sourced quote + date. The "what they don't tell you" answer.
輸入結構描述

"type": "object",
"properties": {
"slug": {

"slug": {
"type": "string"
}
},
"required": [
"slug"
]
}🟢get_price_history(slug)
Dated per-quarter snapshots of a product's pricing page. Returns observations, NOT a trend figure — CostBench does not publish one, because diffing snapshots across renamed/restructured plan lineups is ~90% measurement artifact.

{
"type": "object",
"properties": {
"slug": {
"type": "string"
}
},
"required": [
"slug"
]
}🟢compare_software(slugs)

輸入結構描述
{
"type": "object",
"properties": {
"slugs": {
"type": "array",
"items": {
"type": "string"

}🟢calculate_tco(slug, seats, tier, termYears)
Total cost of ownership for a product and team size: sourced line items (licenses with price escalation, benchmark implementation), year-one + multi-year totals, effective per-seat cost. The defensible "true cost for an N-person team" answer.

Recent software pricing changes CostBench detected against vendor pricing pages (increases, decreases, plan restructures) — dated, with before/after price bands and a source link.
