pack_create

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

With no annotations, the description carries the full burden. It does add real behavioral detail beyond structured fields: the output formats (PDF + HTML), the fact that every claim is validated against the profile, and a failure mode ("fails loudly"). However, it does not say whether the pack is persisted or returned, whether it is idempotent, what permissions or a populated profile are required, or how long generation takes.

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?

Two tight sentences with the deliverables front-loaded in the first line and the validation guarantee second. Every clause carries information; the phrase "fails loudly" is slightly colloquial but communicates a genuine safety behavior rather than filler.

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 generation tool with no annotations and no output schema, the description covers outputs and the validation guarantee but leaves out persistence, return shape (file paths or inline content), and relationship to pack_get/pack_submit. It is adequate to attempt a call but not to predict the result.

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% for the single required parameter, so the description is the only source of semantics and it never mentions job_id at all. The agent can infer from the name that a job identifier is required, but nothing explains which job it should be, or that it is the anchor for tailoring and claim-checking against the profile.

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 ("Generate the application pack") and enumerates the concrete artifacts produced: a one-page A4 CV as PDF and HTML, a cover letter, and how-to-apply guidance. An agent knows exactly what comes out. It does not distinguish itself from siblings such as pack_prompt, pack_submit, or pack_get, so it falls 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?

Usage is only implied: the tool generates a pack, so it is presumably used once a job has been selected and a profile exists. There is no explicit when-to-use statement, no prerequisites, and no routing guidance toward pack_prompt (presumably prompt generation) or pack_submit/pack_get, which an agent must disambiguate from name alone.

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