Detach Tag from Issue

detach_tag
Idempotent

Remove a tag from a MantisBT issue. Permissions depend on whether you own the tag; REPORTER for own tags, DEVELOPER otherwise.

Instructions

Remove a tag from a MantisBT issue.

Requires tag_detach_own_threshold (default: REPORTER) for own tags, or tag_detach_threshold (default: DEVELOPER) for tags attached by others.

Behavior2/5

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

The description indicates a destructive action (remove), but annotations set destructiveHint=false, creating a contradiction. The description does provide permission context beyond annotations, but the contradiction undermines reliability.

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 extremely concise: two sentences, front-loaded with purpose and followed by key permission details. Every sentence adds value.

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

Completeness4/5

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

For a simple tool with two parameters and no output schema, the description covers purpose, permissions, and parameter meaning (via schema). It omits nothing critical for selection or invocation.

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 both parameters with 100% coverage. The tool description adds no additional parameter semantics beyond what the schema offers.

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

Purpose5/5

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

The description clearly states the action (remove) and the resource (tag from a MantisBT issue). It is specific and distinguishes from the sibling tool 'attach_tags' which does the opposite operation.

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

Usage Guidelines4/5

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

The description provides permission thresholds required for the operation, which guides the agent on when the tool can be used. However, it does not explicitly state when not to use it or mention alternatives.

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