## Findings

No check matched anything in these tool definitions.


## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `calculate_inventory`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `classify_activity`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

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

### `verify_result`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

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

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `describe_agent`

- The name "describe_agent" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return fleet-standard capabilities, version, pack digest, and pricing.
```

### `get_factor_pack`

- The name "get_factor_pack" says "get": a word for reading.

Description, as the server wrote it:

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

### `list_factor_packs`

- The name "list_factor_packs" says "list": a word for reading.

Description, as the server wrote it:

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