Gitopia MCP Server

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

No annotations provided, so description carries full burden. Discloses critical behavioral trait: 'Automatically retries on account sequence mismatch' (important for blockchain/Gitopia context). However, lacks description of return value format or success/failure indicators despite no output schema existing.

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?

Four dense sentences covering usage context, core action, behavioral retry logic, parameter requirements, and alternatives. No redundancy. Front-loaded with the 'when to use' clause. Every sentence earns its place.

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 complex mutation tool (9 params) with no annotations and no output schema, the description covers prerequisites, parameters, platform specifics, retry behavior, and sibling relationships. Minor gap: does not describe what the tool returns (PR URL, number, etc.), which would be helpful given no output schema exists.

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 has 0% description coverage, but description comprehensively compensates by listing all 6 required parameters and 3 optional ones. Adds crucial semantic distinctions: 'assignees' (usernames) vs 'labels' (label IDs) vs 'issue_iids' (issue numbers), preventing type confusion between string and integer arrays.

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 specific action ('Creates a pull request on Gitopia') with platform context. Explicitly distinguishes from sibling tool create_feature_branch_pr by clarifying this is for when you've 'already pushed a branch' versus the full cycle, preventing incorrect selection.

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?

Provides explicit when-to-use ('when you have pushed a branch and want to open a PR'), when-not-to-use ('Prefer create_feature_branch_pr for the full branch-commit-push-PR cycle'), and cross-references siblings ('See also: create_feature_branch_pr, git_push'). Clear prerequisite stated.

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