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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds real behavioral value on top: publication cadence ('each weekday'), per-issue structure, and result ordering ('Newest first'). It does not discuss the limit/pagination effect on results, which is the only material gap.

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 compact sentences, front-loaded with what the tool returns, then ordering, then the usage cue. The list of issue components is slightly dense but each element tells the agent what it can expect back, so little is wasted.

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 simple read-only, single-parameter list tool with no output schema, the description adequately conveys what comes back and when to reach for it, and annotations cover the safety profile. A brief note on how many items are returned by default vs. the limit would make it fully self-contained.

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?

Only one parameter (limit) and the schema documents it fully, including the 1-30 range and default of 5. The description adds no parameter-level detail beyond that, so the baseline 3 for high schema coverage 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 and resource ('Recent AgencyGrowth Daily issues') and then describes the actual payload of each issue (job to hand off, tool used, recipe, the catch), which is far more informative than a restated name. It doesn't explicitly name or contrast sibling content tools like get_playbook or read_guide, but the resource is distinct enough that an agent can separate 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?

Gives a concrete triggering condition: 'Use when the user wants a concrete way to automate or delegate a recurring agency task.' That is a clear use context, but there is no explicit when-not guidance and no mention of the alternative siblings (get_playbook, list_playbooks) an agent could pick instead.

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