octo_find_profile_by_name

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It usefully discloses the auth requirement (OCTO_API_TOKEN) and the prefix-matching behavior. However, it does not describe behavior on no matches, multiple matches, or whether exact_match changes the result semantics beyond what the schema already states.

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?

The description is two short sentences plus an auth note, with the core action and key matching behavior front-loaded. Every sentence earns its place; there is no filler, repetition of the tool name, or redundant schema restating.

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 simple two-parameter lookup with an output schema, the description plus schema covers the basics: what it does, how matching works, and that a token is required. Still, with no annotations and several sibling profile-related tools, it lacks explicit selection guidance and edge-case behavior, so it is not fully complete.

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%, so the baseline is 3. The description adds real semantic value by explaining that the API matches from the beginning of the title, which clarifies how the 'name' parameter behaves. It introduces a slight name-versus-title wording inconsistency, but overall it enhances parameter understanding.

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 ('Find a profile by title') and clarifies the matching rule ('matches from the beginning of the title'). It is not a tautology and gives enough resource/scope detail. It does not explicitly distinguish itself from sibling lookup tools like octo_get_profile or octo_search_profiles, so it misses the top score.

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 prefix-matching note implies this tool is appropriate when searching by the beginning of a profile title, but there is no explicit when-to-use/when-not-to-use guidance. Alternatives such as octo_get_profile or octo_search_profiles are never mentioned. The usage context is implied rather than clearly routed.

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