sync_from_source

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

With no annotations provided, the description carries full responsibility for disclosing side effects. It mentions syncing keys but does not explain that it modifies target language files, whether it creates a backup, or the impact of copyValues. This is a significant gap for a write operation.

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 sentence that is front-loaded with the core action and scope. It is efficient and free of unnecessary words, though it omits some detail that might be valuable.

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 are 6 parameters, no output schema, and no annotations, the description is far too brief. It fails to explain return values, side effects, prerequisites, or how parameters like namespaces and copyValues interact. A more complete description is necessary for reliable tool invocation.

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 covers all parameters with descriptions (100% coverage), so the baseline is 3. The description adds minimal semantic value beyond the schema; it simply reiterates the source-to-target language flow. No additional meaning is provided.

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 clearly states the verb 'sync' and the resource 'specific missing keys' with a defined direction (from source to target languages). It distinguishes itself from the sibling tool 'sync_all_missing' by emphasizing 'specific', though it does not explicitly name alternatives.

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 phrase 'specific missing keys' implies this tool is for syncing a selected subset of missing keys rather than all missing keys, but it does not explicitly state when to use this vs. other sync tools or mention alternatives. Usage context is implied, not explicit.

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