## Findings

- **warn** Mentions of other tools or servers in `capitolguide_prep` ([tool-shadowing](https://anlyon.dev/methodology#tool-shadowing))

```untrusted-server-text
The description contains "any other tool", wording about other tools or servers.

description: "Pre-flight readiness check. Run before any other tool. Verifies secrets, KV, DB connectivity,..."
```

- **warn** Annotations that disagree with the tool in `route_between` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "route_between" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"openWorldHint":true}; The input addresses people (input.to): what it sends cannot be taken back.
```

- **warn** Annotations that disagree with the tool in `accessible_route` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "accessible_route" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"openWorldHint":true}; The input addresses people (input.to): what it sends cannot be taken back.
```

- **info** The word "credentials" in `check_access` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "...plex: (visitor_type × zone) → allowed?, credential, escort, lead time, required docs, secu..."
```


## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `accessible_route`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Step-free / accessible directions between two points in the Capitol complex by mobility profile (wheelchair, limited_mobility, stroller, low_vision). Routes over elevators/ramps only, avoids stairs, and surfaces OCAS accommodation contacts. Use this instead of route_between when step-free matters.
```

### `route_between`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Turn-by-turn directions between two points in the Capitol complex. Each point can be a room code, a building name, OR a Metro station / landmark (e.g. 'Capitol South Metro' → '2412 Rayburn', 'Union Station' → '517 Hart', or to the 'Supreme Court' / 'Library of Congress'). Returns an ordered step list with mode (walk/tunnel/subway), minutes, and a flag wherever you re-clear security. Set accessible=true for a step-free route (or use accessible_route).
```

## Changes things (6)

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

### `capitolguide_prep`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn tool-shadowing

Description, as the server wrote it:

```untrusted-server-text
Pre-flight readiness check. Run before any other tool. Verifies secrets, KV, DB connectivity, and KB version + freshness. Returns a structured readiness report.
```

### `check_access`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
What access a visitor needs for a zone of the Capitol complex: (visitor_type × zone) → allowed?, credential, escort, lead time, required docs, security entrance, and the granting authority. INFORMS, never grants — final authority is the member office / Capitol Police / Secret Service. Rules are volatile and live-source-stamped.
```

### `nearby`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Nearest restroom, exit, and food for a specific point — a room code (floor-specific, e.g. the exact nearest bathroom to SH-217), a building name, or GPS coordinates {lat, lon}. Returns specific named venues ranked by distance.
```

### `overview`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Operational snapshot for the caller's tenant: KB version + freshness, queue depths (itineraries / draft meetings / active nudges), and the recent tool-invocation tail. Read-only.
```

### `plan_day`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Optimize a multi-meeting Hill day. Give a list of meetings (each a member name or room code, with an optional time like '10:30a'). Returns a sequenced itinerary: batched by chamber side to minimize cross-campus crossings, the route + minutes between each stop, the cross-campus window flagged, 'leave-by' times when meetings are timed, and warnings for connections too tight to make.
```

### `prohibited_items`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
What you cannot bring into an area of the Capitol complex (security screening). zone: 'capitol_cvc' (the Capitol + Visitor Center — strictest, no food/water), 'gallery' (House/Senate galleries — no phones/cameras), or 'office_building' (the 6 office buildings — food & drink allowed). Always returns the universal weapon/hazard bans too. Volatile — live-source-stamped; confirm at visitthecapitol.gov before you travel.
```

## Only reads (1)

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

### `find_room`

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

Description, as the server wrote it:

```untrusted-server-text
Find a Capitol office by ROOM CODE (e.g. 'SH-217', '2310 Rayburn', '167 Russell', 'H-232'), by MEMBER NAME (e.g. 'Cornyn', 'Ted Cruz', 'Womack'), or by COMMITTEE ('Senate Judiciary', 'Ways and Means', 'House Armed Services'). A room code returns the decoded location plus who currently holds it; a name returns that member's current office; a committee returns its office / principal hearing room. Member & committee assignments are the 119th Congress (volatile, live-source-stamped).
```
