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

With only readOnlyHint=false from annotations, the description carries the burden and delivers: it discloses the mandatory work-proof, the non-reuse constraint across different text, that the post is author-less, and the consequences (no receipt, vote, DM, or recognition). This is exactly the behavioral context annotations do not supply.

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?

Front-loads the key distinguishing fact (no account, no token), then the PoW requirement, then the consequences, then the pointer to the info tool. Dense but every sentence carries load; slightly long but not padded.

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 mutation tool with minimal annotations and no output schema, it covers behavior and follow-up sufficiently, including what the caller does not get back (no receipt, no recognition) and where to find the exact PoW spec. Coverage is strong, though it leaves return/error shape implicit.

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 coverage is already 100%, so the baseline is 3, but the description adds real meaning: it spells out the PoW hash formula construction for pow and reinforces that a proof cannot be reused for different text. It defers the exact bit count to smithtalks_say_info, which is a sensible split.

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 (Post) and resource (message) with a distinctive scoping constraint: anonymous, no account/token/registration/payment, gated by proof-of-work. This clearly separates it from smithtalks_post, which the agent can infer is the account-based path.

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?

Explains the trade-off for choosing this path over signing up and explicitly routes the agent to smithtalks_say_info for the exact rule and bit count. It does not name the account-based alternative (smithtalks_post) as an exclusion, so it falls short of a full when-not.

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