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

Annotations already cover the safety profile (readOnly, non-destructive, closed-world), and the description adds genuinely new context: ordering is newest-first, each entry records actor, token, and channel (ui/api/mcp), and calls are permission-gated. It omits deeper behavior such as whether the journal is complete or truncated by retention, which keeps it off a 5.

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 sentences, front-loaded with what the tool answers, then permissions, then the id source. The long enumerated clause is dense but every listed event type carries information. Slightly heavy for the amount of routing decision it supports.

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 no output schema, the description usefully sketches the return content (events, actor, token, channel) and ordering, which compensates well for a tool whose result shape would otherwise be unknown. It stops short of describing page size behavior or what an empty journal means.

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 id and limit (default 100, max 500, newest first) are already fully documented. The description only repeats the newest-first ordering and the list_secret_files provenance for id, adding no syntax or format detail beyond the schema. 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 resource (the journal of one secret file) and enumerates the record types it contains — uploads, downloads, reader changes, key changes — so the agent knows exactly what it returns. It is clearly distinguished from the sibling list_secret_files, which is named only as a source of ids.

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?

Gives an explicit prerequisite (get the id from list_secret_files) and an explicit access restriction (only the file's author, project lead, or company admin may read it). It does not name an alternative audit tool or say when not to call it, so it falls short of the top tier.

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