## Findings

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

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

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

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

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

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


## Deletes or cancels (3)

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

### `clockify_delete_time_entry`

- The name "clockify_delete_time_entry" 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
WRITE (destructive): permanently delete one time entry. It cannot be undone. DELETE /v1/workspaces/{workspaceId}/time-entries/{id}.
```

### `clockify_stop_timer`

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

Description, as the server wrote it:

```untrusted-server-text
WRITE: stop the running timer of a user (default: you) at end (default now). Clockify answers 404 if no timer is running. PATCH /v1/workspaces/{workspaceId}/user/{userId}/time-entries.
```

### `clockify_update_time_entry`

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

Description, as the server wrote it:

```untrusted-server-text
WRITE: change a time entry's start, end, description, project, task, tags or billable. Only the fields you pass change: the entry is read first and every other field (custom fields included) is sent back as it was. The entry is rewritten (PUT) from a fresh read, so an edit made to the same entry in between (e.g. in the Clockify app) can be lost. A new project without task_id clears the task. GET then PUT /v1/workspaces/{workspaceId}/time-entries/{id}.
```

## Can't be undone (2)

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

### `clockify_detailed_report`

- 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
Every time entry in a date range across the workspace (user, project, client, task, tags, description, start/end, duration in seconds, amount), with totals; newest first, paged. POST reports /v1/workspaces/{workspaceId}/reports/detailed.
```

### `clockify_summary_report`

- 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
Totals of tracked time (seconds) and amounts for a date range across the workspace, grouped by up to 3 levels (default project → time entry), e.g. hours per user per project last month. Respects the filters. POST reports /v1/workspaces/{workspaceId}/reports/summary.
```
