search_discord_symbols

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

With no annotations, the description carries the full behavioral burden. It does disclose a meaningful trait — that results come from a local cache plus live online sources (emojicombos/emojidb) — but says nothing about network failure, latency, rate limits, or whether online fetching can be slow/unavailable. Nothing is contradictory, just incomplete.

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?

A single front-loaded sentence with no filler. Every clause (symbols/aesthetic combos/dividers, local + online sources, named databases) earns its place.

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?

For a two-parameter search tool with full schema coverage this is nearly adequate, but with no output schema and no annotations it would benefit from describing what results look like and how it relates to get_discord_symbols. The overlap with that sibling is left unresolved.

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 100%, so both the 'query' keyword and the 'fetchOnline' default are already fully documented in the schema. The description only adds the names of the source databases, which is marginal beyond the structured fields; baseline 3 applies.

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?

States a specific verb (Search) and resource (Discord symbols, aesthetic combos, dividers), and names the source databases (emojicombos/emojidb). However, it never differentiates itself from the sibling get_discord_symbols, which an agent could easily confuse with a search tool.

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?

There is no when-to-use or when-not-to-use guidance, and no mention of when to prefer this over get_discord_symbols or vice versa. The only hint is the phrase 'locally and dynamically from online' databases, which is not framed as actionable routing advice.

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