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

No annotations are provided, so the description carries the full burden. It does disclose two meaningful behavioral facts: the tool is disabled and would require a member-signed request. But it says nothing about what happens on invocation, whether the disabled state is an error or a no-op, or any permission model beyond 'signed request'.

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 short sentences with the blocking status front-loaded in a bracketed tag. Nothing is wasted, though the '[PLAY]' prefix is opaque and the second sentence could be tighter.

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 deliberately disabled stub with no output schema and no required parameters, the description tells the agent the one thing it needs: do not call this. It is complete for its stated non-operational state, though a pointer to a working alternative would close the loop.

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 admittedly documents both parameters as 'Ignored', which is low-value, but the description adds nothing about tier_id or agent_wallet either — consistent with the tool being non-functional, so no penalty below baseline.

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 the resource (points redemption) and states a critical fact — that it is temporarily unavailable and requires a signed request — but never says what redemption would actually do (spend points for what?). Compared to siblings like redeem_voucher or get_redemption_offers, it does not delineate the actual operation.

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 'not open yet' statement functions as an effective when-NOT-to-use signal, which is real routing value. However, it names no alternative — get_redemption_offers or redeem_voucher are obvious siblings the agent should be pointed to instead. Implied usage only.

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