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

Annotations already declare readOnlyHint=false, openWorldHint=true and destructiveHint=false, so the safety profile is covered. Beyond that, the description only restates that commits are pushed to the linked branch; it says nothing about authentication needs, conflict/force-push behavior, or what happens if no repo is linked — the kind of context that would earn credit over the annotations.

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 tight sentence with the key scope ('Mythex commits', 'linked branch') front-loaded and no filler. Its brevity is what leaves gaps elsewhere, but as structure it is efficient.

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 touching a remote GitHub repo with no output schema and half of its parameters undocumented, this is too thin. An agent is left uninformed about required setup, the purpose of the message parameter, and what a successful push returns.

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 coverage is 50%: project_id is documented in the schema while 'message' has no description anywhere. The description does not compensate — it never mentions the commit message parameter or any format/constraint on either input, so an agent must guess what 'message' means.

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 gives a specific verb (push) and resource (Mythex commits to the linked GitHub branch), which is enough to distinguish it from github_pull and github_link_repo. It stops short of naming those siblings explicitly, so the differentiation is inferred rather than stated.

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 'linked GitHub branch' implies the prerequisite that a repo must already be linked via github_link_repo, but there is no explicit when-to-use or when-not-to-use guidance and no mention of alternatives such as github_status or github_pull.

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