## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `build_legislative_evidence_packet`

- 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
Compile a citation-ready evidence packet for a bill: full official
    record, legislative history timeline, votes with member-level detail, and
    hearings -- each explicitly labeled official vs. derived with source URLs.

    Returns a `how_to_cite` block with a one-line `cite_as` sentence, a human
    `permalink`, a JSON `download_url`, and a `snapshot_id` that changes if and
    only if a cited fact about the bill changes -- so a reader can check later
    whether the citation still holds. Snapshots are NOT archived; the id is a
    change detector, not a way to retrieve an older packet.

    Pass `question` to record what the packet was assembled to answer; it is
    echoed into the artifact so a filed packet carries its own scope.
```

### `trace_legislative_history`

- 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
Full chronological legislative history for a bill: merged timeline of
    actions, version publications, and votes, plus related-bill links.
```

## Only reads (8)

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

### `compare_bill_versions`

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

Description, as the server wrote it:

```untrusted-server-text
Deterministic diff (unified + structured) between two versions of a
    bill's extracted text. Defaults to earliest vs. latest texted version if
    version ids are omitted. Errors if fewer than 2 versions have extracted
    text. Result is labeled 'derived' (computed by Bill Commons, not an
    official document).
```

### `find_similar_bills`

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

Description, as the server wrote it:

```untrusted-server-text
Find bills with similar titles via deterministic trigram similarity,
    across jurisdictions. Labeled 'derived' -- not an official
    cross-reference or companion-bill designation.
```

### `get_active_sessions`

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

Description, as the server wrote it:

```untrusted-server-text
List legislative sessions currently flagged active, optionally
    filtered by jurisdiction (two-letter state code or name).
```

### `get_bill_record`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch the full record for one bill: metadata, sponsors, subjects,
    actions, versions, and vote-event summaries. Look up by canonical
    bill_id (UUID), or by jurisdiction + identifier (+ optional session to
    disambiguate). For a human bill number like HB 123, use
    jurisdiction="NC", identifier="HB 123"; bill_id is for UUIDs.
```

### `get_jurisdiction_coverage`

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

Description, as the server wrote it:

```untrusted-server-text
Return the jurisdiction_coverage state-machine status for one state
    (abbreviation or name), or the full stored coverage matrix if
    state is omitted. Public-registry and unlisted row counts are explicit. Includes bounded retained official-source observation health
    and evidence links. Coverage status measures stored bill/text availability;
    local coverage timestamps can advance on count recomputation. Statewide
    semantic freshness remains unverified, including for GREEN coverage.
```

### `get_vote_details`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch vote event(s) with member-level (yes/no/other/absent) vote
    records. Provide vote_event_id for one vote, or bill_id for all recorded
    votes on that bill.
```

### `list_topics`

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

Description, as the server wrote it:

```untrusted-server-text
List Bill Commons' curated cross-state topic trackers (e.g. artificial
    intelligence, youth online safety, platform accountability,
    cybersecurity, cryptocurrency, data privacy, local government &
    preemption) -- the entry point for "what subjects does Bill Commons
    track across all 50 states + DC" and "how do I get every bill in one".
    Each topic is a title/subject membership rule tuned for precision over
    recall, with a live bill_count and how_to_fetch_bills. This tool does
    not itself return bill rows -- pair it with search_legislation or the
    REST API's /topics/{slug} for the bills.
```

### `search_legislation`

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

Description, as the server wrote it:

```untrusted-server-text
Search FULL BILL TEXT -- not just known-bill-number lookup. `q` is
    matched against titles, descriptions, AND ingested document text via
    Postgres websearch_to_tsquery (supports "quoted phrases", OR, and
    -exclusion, same syntax as a search engine), with a fuzzy pg_trgm
    title-similarity fallback when the exact query has no hits. `q` can
    ALSO be a bill number ("HB 123", "H.B. 123", "hb123" all match) and
    that fast path is tried first. Optionally filter by jurisdiction
    (two-letter state code or name), chamber, and status.

    For a curated cross-state slice of a subject (e.g. "every AI bill in the
    country") rather than an ad-hoc keyword search, call list_topics first --
    its membership rules also match on structured subject tags this
    full-text search does not see.
```
