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

Strong beyond-annotation disclosure: it states the precondition (access must be active), the return field (record_text), the exact failure mode and error code (ACCESS_REVOKED_BY_BAILIFF plus an enforcement receipt), and the blast radius ('Only this one record is affected'). The one gap is that readOnlyHint=false implies a write capability, and the description never clarifies what state the attempt itself creates — the read-flavored wording ('try to open', 'returns record_text') sits in mild tension with that hint.

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?

It is a single dense sentence with nested parentheticals and semicolons, so the key behavior (return value, revoked error, scope) is hard to extract on a first read. Word count is reasonable and no clause is pure filler, but the packaging is convoluted rather than front-loaded.

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?

With no output schema, the description carries the return-value burden and does so (record_text on success, enforcement receipt on refusal), plus preconditions and scope. It does not say what happens outside practice mode or on a non-Consumer-Pulse copy, leaving one edge unspecified, but for a demo-family tool this is largely sufficient to call it correctly.

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 both parameters (matter_id, actor_token) are already documented in the schema. The description only obliquely reinforces matter_id by referring to 'this practice copy' and says nothing about the credential parameter, so it does not add meaning beyond the structured data — 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?

The description names a concrete action and resource — opening the Panel B Q4 dataset lent to your AI — and scopes it to 'Practice mode, Consumer Pulse copy only (Bailiff demo, step 6)'. That distinguishes it from generic siblings like atlas.run_record or atlas.pulse_data, though the distinction is delivered through demo narration rather than a statement of function, so an agent outside the Bailiff scenario has to infer the general behavior.

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?

It tells the agent this is a practice-mode, Consumer Pulse copy tool and identifies its place in the Bailiff sequence ('step 6'), which implies when it is called. However, it names no alternatives and gives no explicit when-not condition or prerequisite (e.g., the order relative to atlas.bailiff_declare or atlas.bailiff_order).

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