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

The price line ($0.10 per call) is real value beyond the annotations, telling the agent this call has a cost. However, it does not explain why readOnlyHint=false and idempotentHint=false for what reads documents, nor does it cover document count/size limits or balance/key prerequisites. With annotations present the bar is lower, so a 3.

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?

Three short sentences, front-loaded with the operation and its output before cost. The closing tagline is slightly decorative but adds a compact use-scenario, so waste is minimal.

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?

The description implies the return shape (findings and open questions), which compensates for the absent output schema, and it discloses pricing. But with 0% parameter documentation the unexplained 'question' input and unspecified document sizing make it only minimally complete for an agent to call correctly.

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%, so the description must carry parameter meaning, and it does not. The 'question' parameter — presumably the focus or framing for the summary — is never mentioned, and 'documents' is only implied, with no format guidance (raw text, paths, URLs).

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 and resource (summarise a set of documents) plus the concrete output shape (findings and open questions), which distinguishes it from extraction or comparison siblings. It does not explicitly name how it differs from near-neighbours like fikra_summarise_contract or fikra_organise_notes, so it stops short of a 5.

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 pick this over sibling tools such as fikra_summarise_contract (single contract) or fikra_organise_notes. The tagline 'Getting the signal out of a reading pile' gestures at a scenario but gives no selection criteria or exclusions.

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