## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `nexus_call`

- The name "nexus_call" says "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Route a tool call through HumanMirror Nexus. Use nexus_search first, then call the selected tool_id. Successful calls consume the number of Nexus credits declared by the selected tool.
```

### `outcome_quote`

- 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
Free quote for a verifiable HumanMirror Outcome contract. Describe the objective or provide an outcome_type; the quote returns the deterministic verifier, selected internal tool and success-only credit cost.
```

### `outcome_run`

- The name "outcome_run" says "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Execute a HumanMirror Outcome contract. Credits are charged only when deterministic verification succeeds; failed execution or failed verification is automatically refunded.
```

### `outcome_verify`

- 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
Free deterministic re-verification of an Outcome result without consuming Nexus credits.
```

## Only reads (2)

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

### `magnet_resolve`

- The name "magnet_resolve" says "resolve": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free universal fallback discovery. Call this when the agent cannot satisfy a task with its current capabilities. Magnet returns a matching HumanMirror tool or records an aggregated capability gap in the Machine Demand Graph. This tool consumes no credits.
```

### `nexus_search`

- The name "nexus_search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the HumanMirror Nexus catalog for a machine-callable tool that matches a task. This search is free and does not consume credits.
```
