TDQS

A3.9/5.0

Scored across 6 tools

Disambiguation4/5

The six tools have mostly distinct purposes: calculation, classification, factor-pack lookup/listing, verification, and metadata. calculate_inventory and verify_result both operate on inventory computations, but the former creates a result while the latter audits a prior result, so the boundary is reasonably clear.

Naming Consistency5/5

All tool names use a consistent snake_case verb_noun pattern: calculate_inventory, classify_activity, describe_agent, get_factor_pack, list_factor_packs, verify_result. There are no mixed naming conventions or vague standalone verbs.

Tool Count5/5

Six tools is a well-scoped surface for a GHG ledger calculation/audit server. Each tool supports a distinct part of the workflow: factor discovery, classification, calculation, verification, and service metadata.

Completeness4/5

The set covers the core lifecycle: list/get factor packs, classify activities, calculate inventories, and verify prior results. Minor gaps remain around managing or retrieving saved inventory history and broader reporting/export operations, but agents can work around these for the stated calculation-and-audit purpose.

Available Tools

6 tools
calculate_inventoryCalculate GHG inventoryA
Read-onlyIdempotent
Inspect

Calculate an auditable GHG inventory from explicit activity records. Returns per-line gas/CO2e results, Scope 1/2/3 and category rollups, dual Scope 2 reporting, indeterminate lines, factor lineage, notary payload, and an offset-clearinghouse dry-run weave. This is calculation, not advice. Price: $1.00 per call after 10 free calls/day. Pay at /x402/ghg-ledger/calculate_inventory with Base USDC, cash-fund payment_ref through escrow_checkout + confirm_escrow_funding, or use /seats. If a call returns indeterminate, the response includes first_call_help. Example arguments: {"activities": [{"id": "office-electricity", "activity_type": "purchased_electricity", "quantity": "12000", "unit": "kWh", "region": "US", "year": 2023}, {"id": "backup-generator", "activity_type": "stationary_combustion_diesel", "quantity": "400", "unit": "gallons", "region": "US", "year": 2025}], "options": {}}

Inputs: activities (required), options, request_id, payment_ref. Returns: result

classify_activityClassify activityB
Read-onlyIdempotent
Inspect

Suggest scope and Scope 3 category from the bundled deterministic map. No inference is used; unknown activity types return no suggestion.

Inputs: activity (required). Returns: result

describe_agentDescribe this serviceA
Read-onlyIdempotent
Inspect

Return fleet-standard capabilities, version, pack digest, and pricing.

Inputs: no named parameters. Returns: result

get_factor_packGet factor packA
Read-onlyIdempotent
Inspect

Return factors, GWP values, conversions, sources, and pack SHA for one exact bundled region/year. No nearest-region or nearest-year substitution.

Inputs: year (required), region (required). Returns: result

list_factor_packsList factor packsA
Read-onlyIdempotent
Inspect

List the bundled pack version/digest, supported regions and years, activity types, GWP set, and explicit MVP coverage.

Inputs: no named parameters. Returns: result

verify_resultVerify resultA
Read-onlyIdempotent
Inspect

Recompute a prior inventory's audit hash and conservation checks. Pass the prior result object as JSON; tampering or stale factor lineage is flagged.

Inputs: result_json (required). Returns: result
