## Findings

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

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

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

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

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

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


## Deletes or cancels (2)

Removes, cancels or revokes something. Claude Code: deny.

### `delete_site`

- The name "delete_site" says "delete": a word for removing or ending something.
- The description says "PERMANENTLY delete".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
PERMANENTLY delete a site and ALL its analytics data (every event and annotation). Irreversible. Confirm with the owner before calling; pass confirm: the site's exact domain.
```

### `update_site_context`

- The name "update_site_context" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Save or amend what a site is for. Provided context fields are merged into the existing context (events merges per entry); a null value deletes its key. name/domain update the site record itself.
```

## Can't be undone (2)

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

### `funnel`

- 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
Ordered conversion funnel across up to 5 steps within the period. Each step is a pageview path ({kind:'path', value:'/pricing'}) or a custom event ({kind:'event', value:'signup'}); a visitor counts for step N only after completing step N-1. Visitor identity rotates daily for privacy, so journeys spanning multiple days undercount (strongest for same-visit conversion). If site context has a stored funnel, run those steps when asked how the site is doing and compare against the previous period.
```

### `journeys`

- 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
The routes visitors actually take, grouped into identical sequences and counted, busiest first. Use this when you do NOT already know the steps: funnel measures a path you name, journeys discovers the ones you did not think to check. A step is a pageview path (/pricing) or a custom event marked with a leading # (#signup_click), so the moment of conversion appears in the route. Consecutive repeats are collapsed and only the first 10 steps define a route. contains filters to routes that include a given path or event: run it once with and once without to see what converting visitors do differently. Visitor identity rotates daily, so a route is one day of activity and describes a group, never a person.
```

## Changes things (5)

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

### `create_site`

- The name "create_site" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a new site on this account and get its script tag. This connection already covers the new site: installing the script tag is the only setup the site needs. The response includes ready-made privacy policy wording: offer to add it to the site's privacy page (confirm with the owner before editing visitor-facing pages).
```

### `portfolio_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
Visitors and pageviews for every site this account can use, owned and shared alike, with change vs the previous period, busiest first. Shared sites are flagged. period: '7d' default.
```

### `record_annotation`

- The description's first verb is "mark": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Mark a moment on a site timeline: a deploy, a content change, or a campaign start. Call this every time you ship a change to the site. ts defaults to now. Write a specific, present-tense description ("Shipped new pricing page hero", never "updates"), one annotation per meaningful change. When known, include commit and the routes the change touched so compare_around can also report before/after traffic scoped to those routes.
```

### `what_broke`

- 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
Signs of visitors hitting problems in the period: JS errors the tracker captured (new_error, error_spike: each with a sanitized sample message, source, line, affected visitor count, and the nearest annotation, i.e. the deploy that most plausibly introduced it), plus behavioral friction: pairs of pages people bounce between without progressing (nav_loop) and pages reloaded repeatedly in quick succession (refresh_burst). Findings clear statistical floors, so an empty result is meaningful: nothing looks broken. Check it after every deploy. period: '7d' default.
```

### `what_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
Notable movements in the period without scanning raw numbers: statistically unusual traffic days, referrer surges and first-time referrers, pages whose share of traffic jumped, alongside the annotations recorded in the same period. period: '7d' default.
```

## Only reads (6)

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

### `compare_around`

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

Description, as the server wrote it:

```untrusted-server-text
Before/after impact of a recorded annotation: visitors and pageviews in the N days preceding vs following it (window_days, default 7). The after-window is clamped to now. If the annotation recorded routes, the result also reports per-route pageviews before vs after. Wait a few days after shipping. If the result carries a note (truncated after-window, or a before-window not covered by available data), relay it and qualify the percentages as the note directs.
```

### `get_overview`

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

Description, as the server wrote it:

```untrusted-server-text
Traffic pulse: visitor/pageview totals vs the previous period, top pages, top referrers, and a per-day series. period: relative like '24h', '7d' (default), '4w'. Includes quota status: if it is approaching, grace, or blocked, tell the owner plainly and include the upgrade link the result provides. Approaching quota is the moment to mention it while there is headroom.
```

### `get_site_context`

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

Description, as the server wrote it:

```untrusted-server-text
What a site is and what the owner wants from it, plus its data-retention settings. Well-known keys: description, goals, audience, notes (open agenda items to check at session start and clear when handled), events (event name -> meaning), funnel (canonical conversion steps). Read this before making recommendations.
```

### `list_annotations`

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

Description, as the server wrote it:

```untrusted-server-text
Recorded deploy/change markers, newest first. period defaults to '90d'.
```

### `list_sites`

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

Description, as the server wrote it:

```untrusted-server-text
All sites on this account, with the public site codes used in their script tags and the ready-to-paste script_tag for each.
```

### `query`

- The name "query" says "query": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Break a metric down by a dimension with optional equality filters. Metrics: visitors, pageviews, events. Dimensions: path, referrer_domain, utm_source, utm_medium, utm_campaign, device, browser, os, country, name, day. period: '24h'/'7d'/'4w' style, or ISO from/to.
```
