## Only reads (6)

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

### `compare_firms`

- The name "compare_firms" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Two firms side by side. Reports each figure with its evidence state and whether the pair is comparable at all: a field neither firm records is not a tie, and a field only one records is not a win. No per-field winner is declared, because the direction of "better" for several of these is a judgement the published scoring model already makes; each firm's grade is returned alongside so the verdict comes from that model rather than from this tool.
```

### `find_firms`

- The name "find_firms" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Firms matching every criterion given. A firm whose record does not carry a criterion is never counted as a match and never silently dropped: it is returned separately under unknown, with the field that could not be tested. Absence is common here, so read counts before treating the matched list as the answer.
```

### `get_evidence`

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

Description, as the server wrote it:

```untrusted-server-text
The stored reading behind a figure: the verbatim quote, the page it came from, and the date we read it. Answers "we hold none" explicitly rather than returning an empty list. `outcome` is load-bearing: a `contradicted`, `contradiction` or `absent` row records what we read, not a figure we publish. Use get_firm for the published figure.
```

### `get_firm`

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

Description, as the server wrote it:

```untrusted-server-text
One prop trading firm. Every figure states whether we hold evidence for it, and a firm whose score range spans more than one band carries no letter grade at all.
```

### `get_rule_changes`

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

Description, as the server wrote it:

```untrusted-server-text
The dated record of what changed, newest first. Every entry states its KIND, and most of this tape is FirmFax correcting its own data rather than a firm changing its rules. Read counts before describing industry activity: a total taken across kinds overstates it.
```

### `list_firms`

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

Description, as the server wrote it:

```untrusted-server-text
Every firm slug and name. Carries no figures, so nothing here needs evidence.
```
