Update your smart link preferences/defaults.
Changes apply to newly created links only — existing links are
not affected. Does NOT delete any data.
Common errors:
- Invalid redirect_type: must be '301' or '302'.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond annotations (idempotent, not destructive), the description adds key behavioral context: changes are not retroactive and no data is deleted. It also mentions common errors with redirect_type, enhancing transparency for the agent.
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 brief and well-structured: purpose first, then scope/safety, then error tips. Every sentence adds value without redundancy.
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 an output schema and detailed parameter descriptions in the schema, the tool description is sufficient. It could optionally mention that all parameters are optional, but the schema's defaults and nullability already convey this. Overall, it covers the necessary context.
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% in the tool description, but the input schema itself provides detailed descriptions for each parameter. The description adds a useful constraint for redirect_type ('301' or '302'), but does not compensate for all parameters. However, the schema carries the semantic load, so a baseline of 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 clearly states it updates smart link preferences/defaults, which is a specific verb+resource. It is distinguishable from siblings like get_preferences (read) and update_smart_link (updates a specific link) by using 'preferences/defaults'.
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 explicitly says changes apply only to newly created links, which clarifies when to use this tool versus alternatives for modifying existing links. It also notes it does not delete data, but does not explicitly name alternative tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool targets a distinct resource or action, from smart link CRUD to health checks, statistics, and YouTube migration lifecycle. There is no meaningful overlap; even similar-sounding tools like get_smart_link and get_smart_link_stats are clearly separated by configuration vs. detailed analytics.
All tools follow a consistent verb_noun pattern with a uniform 'youfiliate_' prefix, e.g., create_smart_link, get_smart_link, delete_smart_link, and start_migration. No mixed conventions or exceptions are present.
With 18 tools, the set is slightly larger than the ideal 3-15 range but remains well-scoped for the dual domain of smart link management and YouTube migration. Each tool has a clear purpose, and the count is not excessive given the feature coverage.
The tool surface covers the full smart link lifecycle (create, read, update, delete, list) plus advanced features like health checks, aggregate/per-link stats, and preferences. The YouTube migration workflow is also complete with connect/disconnect, status, preview, start, list, status, and rollback, leaving no obvious dead ends.
