Ensure a GitHub project view

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

Beyond the annotations (idempotentHint true, destructiveHint false), the description discloses that validation happens before anything is written, that non-board layouts reject column_by, that roadmap date fields cannot be set by the API, and that a token with the project scope is required with a gh auth refresh remedy. It also spells out the project lookup order (owner's boards, repo-linked boards, organization's, then viewer's) so nothing is guessed.

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 core behavior is front-loaded and nearly every clause carries operational information: idempotency, validation, API limits, auth, and lookup order. It loses a point for run-on sentence construction (e.g. the long 'any other project is a title, and no project is Roadmap' clause) that would scan better as ordered points.

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 an 11-parameter, write-capable, open-world tool this is thorough: it covers idempotent semantics, failure modes, authentication and scope remediation, lookup precedence, and API capability limits. An output schema exists, so not describing return values is appropriate, and no operationally relevant gap remains.

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 91%, so the baseline is 3, but the description adds genuine meaning: project values are used as-is when they are numbers/owner-number/URL, otherwise resolved as a whole case-insensitive title among open boards, defaulting to Roadmap, and a bare number takes owner or the repo/working-tree owner. That resolution algorithm is not fully restated in the schema and materially changes how an agent should populate project, owner and repo.

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 first sentence states a precise verb and resource: ensure a saved view exists on a project board, leaving an existing case-insensitive name untouched and creating a missing one via REST with layout, filter, fields, sorting and grouping. That distinguishes it cleanly from the sibling read/create tools (github_project_read, github_project_create) and from github_project_field_ensure.

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?

It makes the ensure-vs-create contract explicit and enumerates the conditions that make a call invalid_argument before any write, which tells an agent when the call will be rejected. However, it never explicitly routes the agent to alternatives such as github_project_read to inspect an existing view or github_project_create for a new board, so the when-not guidance is conditional rather than comparative.

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