pod_update

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

No annotations are provided, so the description must convey behavioral traits. It only says 'update' without explaining what exactly happens (e.g., modifies Podfile.lock, requires network, potential side effects). There is no mention of safety, destructiveness, or required permissions. For a mutation tool, this is a significant 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?

The description is a single sentence of 8 words, immediately stating the action and scope. It is front-loaded and contains no filler or redundant information. Every word 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?

The tool has no output schema, no annotations, and is a mutation operation. The description fails to explain return values, error states, or prerequisites (e.g., that a Podfile must exist). Given the complexity of dependency management, the description is incomplete and leaves the agent with insufficient context to use the tool confidently.

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% with clear descriptions of podName and projectPath. The tool description adds no new meaning beyond paraphrasing the podName parameter. Given the high schema coverage, a baseline of 3 is appropriate; the description does not compensate for any gaps but also does not mislead.

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 clearly states the verb 'update' and resource 'CocoaPods dependencies', with scope 'all or a specific pod'. It distinguishes from sibling tools like pod_install (install) and pod_outdated (list outdated), but does not explicitly differentiate from pod_install, which could be ambiguous. A explicit mention of when to use each would elevate it to 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?

The description provides no guidance on when to use this tool versus alternatives such as pod_install or pod_outdated. It does not mention prerequisites, typical use cases, or when it is inappropriate to use this tool. The agent must infer from the name alone.

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