get_project_changes

Read-only

Compare a GitHub Project snapshot against its checkpoint baseline to return semantic change groups without overwriting the baseline. Initialize a missing baseline when needed.

Instructions

Compare the current Project snapshot with the latest configured checkpoint baseline and return semantic change groups without replacing that baseline. Production may use durable M10 persistence; local development may remain process-local. Can initialize a missing baseline explicitly.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Behavior1/5

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

The description explicitly claims a write capability: 'Can initialize a missing baseline explicitly,' and notes durable M10 persistence in production where initialization would write state. This conflicts with the annotation readOnlyHint=true, which promises no environment modification. This is an annotation contradiction, which caps this dimension at 1 despite the otherwise useful persistence/baseline context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with the core compare operation. The 'Production may use durable M10 persistence; local development may remain process-local' sentence is environment-implementation detail that adds little to tool selection and pads the definition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema and 0% parameter documentation, so the description should carry more of the burden. It covers purpose and baseline behavior but omits return shape, pagination (the 'first' cap of 100), and the semantics of the required owner/number identifiers.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% across 4 parameters. The description only partially illuminates one parameter ('Can initialize a missing baseline explicitly' for initializeIfMissing); owner, number, and first carry no explanation in either the schema or the description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Compare the current Project snapshot with the latest configured checkpoint baseline and return semantic change groups.' This clearly conveys a diff/compare operation. However, it does not distinguish itself from the closely named sibling compare_github_project_state_checkpoint, leaving some ambiguity about which to pick.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

'Without replacing that baseline' implies the tool is for read-only diffing, and 'Can initialize a missing baseline explicitly' hints at the initializeIfMissing condition. But it never names an alternative tool or states when NOT to use this one, so routing guidance is only implied.

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