## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `federal_deadline`

- 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
Compute one federal civil deadline under the Federal Rules of Civil Procedure, FRAP 4 or 28 U.S.C. 1446 and 1447, from the date of the event the rule counts from. Counts under FRCP 6(a) (FRAP 26(a) for an appeal), rolls off weekends and legal holidays in the direction the rule requires, and adds 3 days under Rule 6(d) or FRAP 26(c) only when that rule reaches the period and the method of service calls for it. Returns the due date under the prevailing reading and, when the readings differ, the earliest date (safe for a party computing its own deadline) and the latest date (the floor for arguing someone else was late), with every open question, the rule text, the authority and the countersign status. A deadline a district court's own local rules set is returned by federal_local_deadline.
```

### `federal_local_deadline`

- 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
Compute a deadline a federal district court's own local rules set, for the districts whose local rules this site applies: a motion, an opposition or a reply counted back from the hearing date, and the court's other periods the rules fix. Give the rule as the court's own citation or a row id; rule "list" returns the district's rows and the date each counts from. Counts under FRCP 6(a) and the court's computation rule, applies the days the court's posted schedule closes it and the court's own mail rule, and returns the due date under the prevailing reading with the earliest and latest dates where the readings differ, the federal date a local rule replaces, the time of day where the rule sets one, the court's notes, the rule text and the countersign status. A district this site does not cover returns the districts it does.
```

## Only reads (2)

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

### `federal_count_days`

- The name "federal_count_days" says "count": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Count a period stated in days from a date under FRCP 6(a) or FRAP 26(a): leave out the trigger day, count every day, and if the last day is a weekend or legal holiday roll to the next open day (or, for a period counted backward before an event, to the preceding one). Optionally adds 3 days under FRCP 6(d) or FRAP 26(c) after the roll, for a period that runs after being served. Returns the due date under the prevailing reading, and the earliest and latest dates when observed or closure days make the readings differ. Use this for a period no specific rule row covers, such as one set by a court order. With court_open_days, counts only days a district court is open instead, for a local rule that states its period that way.
```

### `federal_legal_holidays`

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

Description, as the server wrote it:

```untrusted-server-text
List the legal holidays for a year under FRCP 6(a)(6) and FRAP 26(a)(6): the eleven days in 5 U.S.C. 6103(a), the Friday observed for a Saturday holiday (5 U.S.C. 6103(b)(1)), the Monday observed for a Sunday holiday (Executive Order 11582), and the days the President closed the executive branch. These are the days a federal deadline rolls off. Each observed or closure day says which reading treats it as a legal holiday and that the point is not settled. State holidays are not applied.
```
