session_sync

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

No annotations are provided, so the description carries the full burden. It discloses that 'rename' automatically mutates both Claude chat and Chrome group, while 'color' and 'detect' only map/read and return /color and /rename commands. This prevents an agent from assuming every action has the same side-effect profile.

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 compact, front-loads the general purpose, and uses a consistent quoted-action structure for the three modes. No sentence is wasted and the detail is proportional to the tool's complexity.

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?

With no output schema, the description appropriately states what each action returns ('returns the /color command', 'returns matching /rename + /color commands') and what 'rename' mutates. All parameters are already covered by the schema, and the tool is simple enough that the description leaves no essential calling information missing.

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?

The input schema already documents all three parameters, so the baseline is 3; the description adds value by explaining what each action does with those parameters and gives a concrete example ('fix chrome mcp') for the 'description' field. This goes beyond the schema's terse 'For color: sync theme color' and clarifies the mapping semantics.

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 opens with a specific verb and resource ('Sync Claude session name/color with Chrome tab group') and then defines three discrete actions with distinct outcomes. This clearly differentiates session_sync from sibling browser-navigation and devtools tools, which focus on tab control or debugging rather than Claude-to-Chrome synchronization.

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 establishes a clear context for when to use the tool: whenever the user wants to synchronize Claude session naming or color with a Chrome tab group. It does not explicitly name alternatives or exclusions, but the action-specific guidance ('rename', 'color', 'detect') tells an agent which mode to choose for a given intent.

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