get_halal_index_summary

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

With no annotations, the description carries the full burden, and it does disclose useful provenance context: asset count (820), the AAOIFI standard, and the Zenodo DOI, all of which signal data source and authority. However, it says nothing about the return format, whether the data is static or refreshed, or versioning of the methodology.

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 purpose is stated immediately followed by qualifying metadata that 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 zero-parameter read-only tool this is close to sufficient, and the metadata adds credibility. Still, with no output schema and no annotations, the description does not convey what the summary actually contains (which statistics, what methodology sections), leaving the return value underspecified.

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 there is nothing for the description to disambiguate; the baseline for a no-parameter tool is 4. No parameter documentation is needed here.

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 names a specific verb ('Get') and resource ('institutional statistics and methodology summary for the Halal Crypto Index'), and the scope details (820 audited assets, AAOIFI standard, Zenodo DOI) sharpen what the tool returns. It is distinguishable from listing or compliance-checking siblings by implication, though it never explicitly contrasts itself with them.

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 guidance on when to use this tool rather than check_shariah_compliance or list_halal_coins, nor any stated prerequisites. The agent must infer that a summary/statistics call is the right choice for overview information.

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