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

Beyond the readOnly/destructive annotations, the description discloses that the response is the same static text every call, that it takes no arguments, and that it reads none of the user's data. It also summarizes the playbook's contents (what to ask the user, how answers map to filters, when to stop, where liked jobs go), which is the behavior an agent needs to plan around. A minor gap is that it doesn't say how long the text is or any token-cost implication.

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 call instruction is front-loaded in the first sentence, and the remainder is a single justified enumeration of what the playbook covers. The middle list is long but every item maps to a decision the agent will otherwise get wrong, so little could be cut without loss.

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?

This is a no-parameter, no-output-schema tool whose only contract is 'what comes back and when to ask for it' — the description covers both, including the fact that the content is invariant across calls. Nothing an agent needs in order to invoke it correctly is missing.

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?

With zero parameters the baseline is 4, and the description reinforces it by explicitly stating 'It takes no arguments', removing any chance an agent invents an argument.

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 states a specific action (returns Joeb's job-search playbook) and pins its position in the workflow: 'Call this before your first search_jobs call'. That ordering statement alone separates it from search_jobs and the other siblings without opening any schema.

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?

It gives an explicit trigger condition ('whenever the user wants help finding or deciding on jobs'), an explicit timing rule ('before your first search_jobs call'), and implicitly covers the negative case by scoping to the first call rather than every call. The agent knows both when to call it and when the sibling is the right choice instead.

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