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

### `assess_trip`

- 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 long-description

Description, as the server wrote it:

```untrusted-server-text
Assess one trip: current disruption status for its destinations and dates.

    Use this tool when the user asks whether a specific trip is affected by
    strikes, weather, transport disruptions or other travel risks.
    Give the destinations and the travel window (date_from/date_to,
    YYYY-MM-DD). Destinations are the EU-27 ISO2 codes (Greece = "EL") PLUS the
    non-EU27 countries we actively monitor: Norway ("NO", rail via Entur, live),
    the United Kingdom ("UK" or "GB", transit via TfL, live), and Switzerland
    ("CH", rail via SBB — key-pending, so it is reported as a declared blind
    spot until the feed is keyed, never a false all-clear). A code we do not
    monitor is rejected with {"error": "unknown_country"} rather than silently
    all-cleared. Returns a Decision-Support answer, not raw data:
      * travel_status: NORMAL | MINOR_DISRUPTION | MAJOR_DISRUPTION;
      * actionable_lines: per-event DECISION-IMPACT guidance — what the
        disruption means for THIS trip and what to do (e.g. "affects regional
        trains, not airports -> take a road airport transfer, leave ~30 min
        earlier"), or a clearly-labelled "nothing material" line when calm;
      * confidence: a LABELLED model output (coverage/corroboration/recency/
        blind-spots blend, not a probability) — read its caveats;
      * sources_checked: proof of what was monitored (sources_ok, blind spots);
      * events + caveats.
    Sub-floor noise (a deep, far-field seismic blip) is omitted; calm is a
    monitoring result for the window, never an invented forecast. Invalid
    inputs return an explicit {"error": ...}; nothing is fabricated.

    Top-level MCP-facing structure (additive; existing fields preserved):
      * presentation: a three-section block — affects_your_trip[] (each
        item with verified_sources[] as display-ready names, source_count,
        corroborated flag (≥2 distinct sources), an honest for_you line
        bound to destinations+dates only, report_url, first_detected_at,
        last_verified_at); doesnt_affect_your_trip (the proof-of-work
        pile — shown[] of {headline, reason_excluded}, additional_checked_count,
        summary_line, total_checked); next_steps[] (deterministic — re-check
        date, aviation-handoff watch when blind spot, per-active monitor URLs);
      * track_record_ref: lean {window_days, flagged, ended, still_active,
        monitoring_since, url} — numbers + URL only, no narrative;
      * suggested_next_call: {tool, context} — the suggested follow-up
        (watch_trip) when the user wants continued monitoring.
    These exist so an LLM consumer can quote verbatim — every fact is
    traceable to a named source or an input field, never invented.

    Destinations also accept natural input: IATA airport codes (e.g. 'TSR',
    'AMS', 'ZRH') and major city names (e.g. 'Timișoara', 'Amsterdam',
    'Zürich', 'London'), resolved deterministically to a monitored country
    code. The response includes a 'resolved' list ([{input, country, kind}])
    disclosing how each token was mapped (e.g. 'TSR -> RO via iata-airport').
    A token that resolves to a country we do not monitor is rejected with
    {'error': 'unknown_country'}; a token we cannot resolve at all is rejected
    with {'error': 'unknown_destination', 'tokens': [...]} — we reject rather
    than guess.

    Pass `lang` (e.g. "de", "ro", "pl", "fr", "es", "it"; default English) to
    answer in the traveller's language — useful for a traveller
    in a country whose language they do not speak. The response then carries a
    `localized` block with the status sentence, an honest reassurance line
    (calm ONLY when status is NORMAL), the decision-impact lines, AND — never
    dropped — the localized caveats + blind_spots. Source-derived free text the
    traveller cannot read (an event headline in the source language) is
    AI-translated via Gemini and carries the label "AI-translated — verify
    against the linked… [1230 more characters not shown]
```

### `country_tourism_profile`

- The input takes a statement or command to run (input.code), which can change anything it can reach.
- 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
Tourism profile for one EU-27 country — a decade of Eurostat data.

    Use this tool for questions about a country's tourism statistics,
    seasonality or visitor mix, not for live disruptions.
    Pure projection of the published artifacts (countries/<code>.json +
    competitiveness.json): yearly nights/arrivals totals with YoY, average
    stay, seasonality (peak month and peak-to-mean ratio, formula disclosed),
    domestic vs foreign visitor share, recovery vs 2019, growth vs the EU
    average, and computed competitiveness insights (each labeled with its
    basis). Every number is computed from the same public dataset the site
    serves — nothing narrated, nothing estimated; links carry the citable
    page + raw JSON. `code` is EU-27 ISO2 (Greece = "EL"). Unknown country ->
    {"error": "unknown_country"}; missing artifact -> {"error": "unavailable"}.
    
```

### `watch_trip`

- The description's first verb is "start": a word for a change.
- Findings: info long-description

Description, as the server wrote it:

```untrusted-server-text
Start monitoring one trip for disruption changes over time.

    Use this tool when the user wants ongoing monitoring of a trip rather
    than a one-off assessment (for a one-off answer, use assess_trip).
    Persists the trip as a monitored object and returns its initial assessment
    plus a random, unguessable trip_id AND a one-time `owner.owner_token`.
    Store BOTH: the trip_id is the (public, shareable) URL handle, the
    owner_token is the private key needed to change or stop the trip later.

    CREATE vs REFRESH: called with just destinations+dates it CREATES a new
    trip every time (it does NOT dedupe on identity — that is deliberate, so
    nobody can reach your trip by guessing your itinerary). To update an
    existing trip (change its label or webhook), call again passing BOTH its
    `trip_id` and `owner_token`; a missing/wrong token is rejected. Each
    pipeline run then re-evaluates the trip and appends an update ONLY when
    something materially changes (a new/cleared event, a severity/status shift,
    or a travel_status change) — never on a calm tick.
    Args: destinations — EU-27 ISO2 codes (Greece = "EL") plus the non-EU27
    countries we monitor: Norway "NO" (Entur, live), United Kingdom "UK"/"GB"
    (TfL, live), Switzerland "CH" (SBB, key-pending → declared blind spot until
    keyed); date_from/date_to (YYYY-MM-DD); optional label. An unmonitored code
    is rejected with {"error": "unknown_country"} rather than a false all-clear.
    Returns {trip_id, assessment, created_at}; invalid inputs return an explicit
    {"error": ...}.

    Destinations also accept natural input: IATA airport codes (e.g. 'TSR',
    'AMS', 'ZRH') and major city names (e.g. 'Timișoara', 'Amsterdam',
    'Zürich', 'London'), resolved deterministically to a monitored country
    code. The initial assessment includes a 'resolved' list
    ([{input, country, kind}]) disclosing how each token was mapped
    (e.g. 'TSR -> RO via iata-airport'). A token that resolves to a country we
    do not monitor is rejected with {'error': 'unknown_country'}; a token we
    cannot resolve at all is rejected with
    {'error': 'unknown_destination', 'tokens': [...]} — we reject not guess.

    Pass `lang` (e.g. "de", "ro", "pl"; default English) to localise the
    initial assessment into the traveller's language: the returned
    assessment carries the same `localized` block as assess_trip (honest
    reassurance, AI-translated-and-LABELLED source text, and the localized
    caveats + blind_spots that are never dropped). Localization never becomes a
    false all-clear; the aviation handoff discloses the blind spot, not coverage.

    Pass `audience` ("tmc" | "hotel" | "ota" | "tour_operator") for role-specific
    operational actions — the initial assessment then carries the same `persona`
    block as assess_trip (audience + per-event role actions, projected from the
    audience-tagged recommendations). Built for the B2B travel-risk buyer.

    Pass `notify_webhook_url` (https only) to get PUSH delivery: on every
    MATERIAL change the radar POSTs the update record (summary, status
    transition, event report URLs) to your URL, signed HMAC-SHA256 over the
    raw body (header X-TravelTrends-Signature: sha256=<hex>). The response
    then includes `notify.secret` — shown ONLY once, never published; store
    it to verify signatures. To change or remove the webhook later, re-call
    with the trip_id + owner_token and the new notify_webhook_url (or "" to
    remove delivery). After 5 consecutive delivery failures the webhook is
    disabled with an honest notify_disabled entry in the trip's updates log.
    Non-https or private-network URLs are rejected with
    {"error": "invalid_webhook_url"}.
    
```

### `whats_changed`

- 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
Report only what changed for a watched trip since a checkpoint.

    Use this tool when the user asks for news on a trip already registered
    with watch_trip; for the stored notification log rather than a live
    diff, use get_trip_updates_since. Recomputes the
    trip's current assessment and diffs it against the checkpoint at/just-
    before `since` (or the last evaluation when `since` is omitted). Returns
    {material, summary, added_events, removed_events, changed_events,
    previous_travel_status, travel_status, confidence_from, confidence_to}.
    `summary` is a plain-language line ('Since your last check: rail strike
    CONFIRMED (was: announced); a road closure cleared; confidence 63->71%').
    A non-material tick returns material=False with a clearly-flagged 'No
    material change' summary — never invented churn. `since` is an optional
    ISO-8601 timestamp (e.g. the user's last-seen time). Id is regex-validated
    (^trip-[a-z0-9-]+$); unknown id -> {"error": "not_found"}, malformed id ->
    {"error": "invalid_trip_id"}.

    The response also forwards the presentation blocks from the current
    assessment so the LLM consumer has full context alongside the delta:
    presentation (affects_your_trip / doesnt_affect_your_trip / next_steps),
    track_record_ref (90-day counts + URL), and suggested_next_call
    (the suggested follow-up action). Forwarded in both material=True and
    material=False branches; absent if upstream did not compute them
    (legacy code paths) — never fabricated.

    `audience` (optional: tmc | hotel | ota | tour_operator) attaches the
    same `persona` block as assess_trip/watch_trip to the change alert —
    audience-tagged actions for the events currently affecting the trip, so
    the alert itself carries the operational next step. Unknown audience ->
    honest error listing valid_audiences.
    
```

## Only reads (4)

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

### `country_briefing`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get today's published daily briefing, pre-formatted for end users.

    Use this tool for a general "what is happening today in EU travel"
    question that is not tied to one specific trip.
    Returns the same payload as the underlying daily briefing artifact:
    headline counts, one plain-language headline per active event,
    monitoring coverage (sources_ok / blind_spots_count), backtest trust
    figures, and a caveats list. Always relay caveats alongside numbers.
    Optional ``country`` (EU-27 ISO2 alpha-2, Greece = "EL") narrows the
    events list only — headline_counts / monitoring / trust stay
    EU-27-wide, as flagged in the returned note. Missing artifact returns
    ``{"error": "unavailable"}``.
    
```

### `explain_silence`

- The name "explain_silence" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Explain why a watched trip has produced no updates.

    Use this tool when the user asks why they have not heard anything about
    a watched trip. Returns {recheck_count, last_checked} (proof the trip
    was actively monitored),
    {suppressed:[{what, domain, country, score, floor, reason}]} (what we saw
    for your destinations and dropped below the disclosed relevance floor —
    e.g. a deep quake at modelled felt-intensity 3.39 < floor 4.0),
    {confidence_during_window}, and {blind_spots:[{domain, country, note}]} —
    domains/countries we do NOT monitor live, so silence there is NOT a
    guarantee (e.g. aviation-IT blind spot => silence does not cover flights).
    `since` optionally scopes the recheck window. Id is regex-validated;
    unknown -> {"error": "not_found"}, malformed -> {"error": "invalid_trip_id"}.
    
```

### `get_trip_updates_since`

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

Description, as the server wrote it:

```untrusted-server-text
The watched-trip updates log filtered to entries AFTER `since`.

    The notification payload: everything logged for the trip strictly after
    the `since` ISO-8601 timestamp (the user's last-seen time), oldest-first.
    Returns {trip_id, since, new_update_count, updates}. Use this tool to
    fetch the stored update entries the user has not seen yet; for a live
    recomputed diff, use whats_changed instead. An empty `since` returns the whole
    log. Id is regex-validated (^trip-[a-z0-9-]+$); unknown id ->
    {"error": "not_found"}, malformed id -> {"error": "invalid_trip_id"}.
    
```

### `list_events`

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

Description, as the server wrote it:

```untrusted-server-text
List detected travel-disruption events for EU-27 tourism.

    Use this tool to browse or filter current disruption events across
    countries; for a question about one specific trip, use assess_trip.
    Events are deterministic, rule-based detections over published live
    snapshots and monthly indicators — thresholds are disclosed in each
    event record; nothing is model-generated here. Filters: status (e.g.
    "active"/"resolved"), country (EU-27 ISO2, Greece = "EL"), domain
    (e.g. "weather", "aviation"), min_severity on the ordered scale
    info < watch < warning < severe. Returns {count, events, filters};
    on missing index returns {"error": "unavailable"}.
    
```
