add_feature_to_app

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

No annotations are provided, so the description carries the full behavioral burden. It implies a mutation (integrating and linking a repository), but does not disclose side effects, whether it modifies repository structure or config, whether the operation is reversible or idempotent, or any permission requirements — significant gaps for a write-like operation.

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

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

A single efficient sentence with no wasted words, front-loading the verb. It is appropriately sized, though it could arguably trade a few words for a prerequisite or side-effect note.

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

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

For a mutation tool with no annotations and no output schema, the description leaves out prerequisites, side effects, and expected outcome. An agent knows what the tool does at a high level but not enough about the operational context to invoke it confidently.

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

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

Schema description coverage is 100%, with both appName and featureRepository documented in the schema with examples, so the baseline is 3. The description adds no meaning beyond the schema, only reinforcing that the feature may be existing or new.

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

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

States a specific compound verb ('Integrate and link') and resource ('an existing or newly created feature into an application workspace'), which clearly distinguishes the action from siblings like create_feature or clone_feature_template. It is clear what the tool does, though it does not name a sibling to contrast against.

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

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

The phrase 'existing or newly created feature' implies this is the linking step that follows feature creation, which gives some contextual usage signal. However, there is no explicit when-to-use guidance, no stated prerequisites (e.g., the app and feature repositories must already exist), and no mention of alternatives such as create_feature.

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