## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `send_feedback`

- The name "send_feedback" says "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Passes the user's feedback about the timetable service on to its developer (what worked, what did not, wishes). Only call it when the user has said they want to give feedback, and send what the user said in their own words (you may shorten it; any language is fine). Never include teacher names, other personal data or the school's data files. Tell the user briefly that it was sent. Nobody replies through this channel - if the user wants an answer, give them the support email timetablingengine.support@gmail.com.
```

## Changes things (1)

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

### `create_schedule`

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

Description, as the server wrote it:

```untrusted-server-text
Starts calculating the full timetable from the 8 input files (validate them first). Returns a job_id at once; the calculation takes about 5-8 minutes. Then keep calling get_schedule_result with the job_id in the same reply until it is done.
```

## Only reads (3)

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

### `get_interview_guide`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the interview guide: which questions to ask the user, default values, engine limits and the exact format of the 8 input files. Call this first.
```

### `get_schedule_result`

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

Description, as the server wrote it:

```untrusted-server-text
Gets the status or result of a job from create_schedule (or a slow validate_input). While running: progress. When done: a compact timetable as text plus a link (valid 1 hour) to the full JSON result. view='classes' (default) = one table per class, 'teachers' = one per teacher incl. preparation time, 'summary' = key figures and lists of classes/teachers only. Use 'names' to get only some classes/teachers (recommended for big schools). If impossible: the reasons.
```

### `validate_input`

- The name "validate_input" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Checks the 8 input files in a few seconds without creating a timetable: file structure, engine limits and a capacity analysis (enough teachers/time?). Returns VALID (with warnings) or INVALID (with reasons). Always run this before create_schedule.
```
