v0.2.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true. The description adds useful behavioral context by clarifying that the latest checkpoint is not replaced, which confirms a non-mutating comparison operation without contradicting 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?
The description is a single front-loaded sentence with no filler. It states the operation, target, and key non-mutating constraint 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?
The description is adequate for selecting a read-only comparison tool, especially given the annotations. However, it leaves parameter meanings and comparison result behavior unstated, and the schema provides no parameter descriptions while 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 description coverage is 0%, and the description does not explain any of the three parameters. It does not clarify what owner, number, or first mean, nor how 'first' controls pagination or comparison scope, so it fails to compensate for the undocumented schema.
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 names a specific verb (compare) and resource (current normalized state of an allowed GitHub Project vs. latest stored checkpoint). It implicitly distinguishes itself from the sibling create_github_project_state_checkpoint by stating 'without replacing that checkpoint,' though it does not name other similar read/comparison siblings.
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?
Usage is implied by the non-replacement condition: use this to compare current state against the latest checkpoint rather than to create or update one. It does not explicitly say when to use this instead of get_github_project_snapshot, analyze_github_project_state_gaps, or analyze_github_project_reconciliation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
