context_sync_guidance

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

With no annotations, the description carries the full burden of behavioral disclosure. It fails to state whether the tool performs a read-only operation, what the output looks like, or any side effects. The phrase 'provides guidance' suggests a non-mutating action, but that is implicit and not explicitly confirmed.

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 short and front-loaded, but it may be too terse to be useful. It states the purpose in one sentence without unnecessary fluff, but the sentence is vague and doesn't earn its place by providing actionable details. It's concise but lacks substance.

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?

Given there is no output schema and no annotations, the description needs to explain what the tool returns and how it fits into the larger workflow. The description is minimal, leaving ambiguity about the nature of the 'guidance' and how it relates to sibling tools like timeline_reconstruction or update_context_file. This is a clear gap for a 4-parameter tool.

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 100%, so all parameters have descriptions. The description adds minimal value beyond the schema, only echoing 'timeline data' and 'sync type.' It doesn't clarify the relationship between parameters or the expected format of timelineData, but the schema already handles basic semantics, so a baseline 3 is appropriate.

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 states a clear resource ('project contexts') and a general action ('syncing') but uses the weak verb 'provides contextual guidance,' which is vague and doesn't distinguish this tool from siblings like 'request_thinking_guidance' or 'timeline_reconstruction.' It conveys the core idea but lacks specificity.

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 description implies use cases via 'based on timeline data and sync type' but gives no explicit when-to-use guidance, prerequisites, or comparison to alternative tools. There is no mention of when this tool is preferred over related siblings, leaving the agent to guess.

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