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

With no annotations provided, the description carriees the full behavioral burden — and it does so thoroughly: it discloses the write/cost tier, possible approval gating, the default-count no-bulk policy, the 'never invents from empty corpus' guardrail, and the human_pre_gate constraint. This lets an agent anticipate consequences well beyond simply 'this creates something.'

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 dense but every sentence earns its place: front-loaded action, clear constraints, explicit alternatives, and a compact approval note. There is no added fluff or restatement of the schema. It is longer than a one-liner because it genuinely needs to carry approval, cost, and semantic fidelity rules.

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 complex, write-tier tool with no output schema, the description is complete enough for correct selection and invocation. It tells the agent what the tool produces, when to use it instead, how many angles to create, why not to overuse it, and what behavioral guards apply — so the agent can safely use the tool and set expectations.

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 the baseline is 3 — the schema already documents count, theme, and companyId. The description reinforces the count constraint ('do NOT bulk-fill the queue') and adds usage intent, but it does not materially redefine any parameter beyond what the schema already gives.

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 names a specific action ('Mint the NEXT content angle(s)'), the source ('from the company's corpus'), and the output ('into content_ideas + Command Center cards'). It explicitly differentiates from day-to-day retrieval tools like list_knowledge / read_knowledge / list_corpus_inventory, so an agent can tell it apart without reading scores of sibling definitions.

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 gives concrete when-to-use conditions ('only when a human-facing card is needed... weekly queue, a Held post, operator asked') and when NOT to use it ('For day-to-day drafting, prefer list_knowledge / read_knowledge / list_corpus_inventory'). This is explicit decision guidance, not just a vague keyword hint.

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