save_teams_channel_alias

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

There are no annotations, so the description carries the full behavioral burden. It does disclose the upsert-like behavior ('Create or update'), but it does not mention permissions, overwrite semantics in detail, or what the tool returns, leaving important behavioral context undisclosed.

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?

One short sentence with no filler. It front-loads the action, names the object, and gives the required identity fields efficiently.

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, no output schema, and no parameter descriptions, this is under-specified. An agent is left to infer alias naming rules, response behavior, and whether an existing alias is overwritten, so the description is not complete enough for fully confident invocation.

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 0%, so the description must compensate. It only restates the parameter roles: alias is the named alias, and team_id + channel_id identify the channel. It does not explain alias format, uniqueness, or the relationship between team and channel beyond what the parameter names already suggest.

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?

The description states a specific action ('Create or update') and a clear resource ('a named alias for a Teams channel'), and even names the identifying parameters. This clearly distinguishes the tool from its siblings list_teams_channel_aliases and delete_teams_channel_alias.

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 intended use is implied: call this tool when you want to create or update a channel alias. However, it does not explicitly say when not to use it or which sibling tool to use instead, such as listing or deleting aliases.

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