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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuinely new behavioral detail beyond that: results are newest-first and every item includes a summary and a link. It stays silent on pagination or result-count behavior, which keeps it short of a 5.

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?

A single sentence with no filler, front-loaded with the identity of the resource and then layered with content types, scope, ordering and payload. Every clause earns its place.

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 two-optional-parameter read tool with no output schema, the description is nearly complete: it states ordering, per-item contents (summary and link) and cross-network scope. The only omission is whether results are truncated or paginated, which matters mildly given the limit cap of 10.

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%, with limit (1-10, default 5) and network (slug from list-networks, default all) fully documented in the schema. The description only echoes the network scoping ('every network or one') and adds no format or syntax detail beyond what the schema already provides, so the baseline 3 applies.

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?

Names a specific resource (BitBasic news posts), enumerates the content categories covered (upgrades, governance, advisories, reports), plus ordering (newest first) and what each item carries (summary and link). That makes it distinguishable from list-oriented siblings like governance-proposals or network-status, though it never explicitly contrasts itself with them.

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 implied rather than stated: 'on every network or one' signals the network filter is optional and defaults to all. There is no explicit when-to-use versus an alternative tool, and no guidance on when to prefer a more targeted feed (e.g. governance-proposals) over this broad news listing.

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