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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so safety is covered structurally. The description adds that the content is AGENTS.md documenting private payments via CLI or MCP server, which is useful framing, but it does not say what is returned when no section is supplied (full document? index?) or how an invalid section name is handled.

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 no filler; the subject matter is front-loaded in the 'AGENTS.md:' lead. The colon-style opening is slightly terse but reads cleanly and the parameter example follows immediately.

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 single-parameter read-only doc lookup with no output schema, the description covers the essentials of what the tool returns and how to target a section. It should still state the no-argument fallback behavior and roughly what the returned content looks like (markdown text) to be fully self-sufficient.

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 0%, so the description must carry the parameter meaning — and it does, explaining that 'section' is optional and accepting either a number or a title, with concrete examples ('4', 'Recipes'). The only gap is the undisclosed default behavior when the parameter is omitted.

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 identifies the resource (AGENTS.md guidance on making private payments via the Blackpool CLI or local MCP server) and implies retrieval, which distinguishes it from the analytics/assets/fees/status siblings. The retrieval verb itself is only implicit — it never literally says 'returns' or 'reads' a section — but an agent can still infer the tool's function.

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: consult this when you need to learn how to make private payments. There is no explicit statement of when to prefer it over other tools, no mention of calling it before other operations, and no exclusion guidance. Adequate but inferential.

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