get_discord_syntax_guide

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 is a zero-parameter, inherently read-only reference, so there is little risk to disclose, but it says nothing about the form of the returned content or its size/length despite being billed as 'comprehensive'.

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; the enumerated topics are the useful content. The list is long but each item adds scope information rather than padding.

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 no-param, no-output-schema lookup tool the description is minimally adequate: it tells the agent what topics are covered but not how the guide is returned or how it relates to the other Discord formatting tools it sits beside. Nothing is misleading, but routing information is absent.

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 tool takes zero parameters, so per the rubric the baseline is 4. There are no inputs whose meaning the description could or should clarify.

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 ('Get') and resource ('reference guide of all Discord Markdown shortcuts, techniques, mentions, timestamps, subtext, spoilers, and internal navigation links'), enumerating the covered topics. It is clear what the tool does, but it doesn't distinguish itself from nearby siblings like get_discord_symbols or format_discord_mention, which could plausibly overlap.

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 gives no when-to-use context, no prerequisites, and no pointer to alternatives among the many Discord formatting/mention siblings (get_discord_symbols, format_discord_mention, resolve_discord_mentions). An agent must infer that this is the general reference and those are narrower tools.

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