delete_announcement_with_confirmation

DestructiveIdempotent

Delete a Canvas course announcement permanently after running optional safety checks. Use dry-run mode and title matching to verify before removal.

Instructions

Delete an announcement with optional safety checks.

Permanent — Canvas may retain a recycle-bin copy depending on admin settings.

Input Schema

TableJSON Schema

dry_runNoVerify but don't actually delete (default: False)
announcement_idYesAnnouncement ID to delete
course_identifierYesCourse code or Canvas ID
require_title_matchNoOnly delete if title matches this string exactly
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate idempotent and destructive behavior. The description adds a note about permanence and potential recycle-bin retention, which provides extra context but does not go into detail about the safety checks or failure modes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is exceptionally concise, consisting of two short sentences with no redundancy or unnecessary details. It efficiently conveys the core action and a key consequence.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the basic action and permanence but lacks information on the confirmation process, outcomes of dry-run, or error handling. Given the lack of an output schema, more context on behavior would be beneficial, but the description is not misleading.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already provides descriptions for all parameters, achieving 100% coverage. The tool description does not add any additional semantic meaning beyond what the schema already explains, so a baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool deletes an announcement and mentions optional safety checks, which adds some specificity. However, it does not explicitly differentiate from the sibling 'delete_announcement' tool, which could cause confusion.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives like 'delete_announcement' or 'bulk_delete_announcements'. It lacks context on scenarios where confirmation or safety checks are needed.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
