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

Despite readOnlyHint and idempotentHint already covering safety, the description adds extensive behavioral context: page size limits, char_offset continuation, no separators when concatenating, privacy redaction, no substitution of corrected text, lack of snapshot consistency, stable ordering, untrusted-data warnings, and explicit oversized-segment failures. This goes far beyond the annotations and directly affects how the agent should process output.

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?

The description is long but every sentence adds a distinct invariant or operational detail required for correct use. It opens with the core purpose and exclusion, then proceeds through pagination, data semantics, safety, and budget; no filler or tautological sentences are present.

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?

This is a paginated, edge-case-heavy read tool, and the description addresses cursor traversal, continuation, quoting rules, stability, redaction, failure behavior, budget, and trust. An output schema exists, so return-value shape does not need to be restated; nothing material needed to call the tool correctly is missing.

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 100%, and the schema already documents cursor as an opaque next_cursor that should be omitted for the first page and session_id as an exact public session ID with the access restriction. The description largely restates this, though it adds the operational rule to reuse the same session_id while following cursors; that is marginal enrichment over the schema, so a baseline 3 is appropriate.

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 specific verb ('Read'), a precise resource ('saved final transcript segments from an ended or interrupted public session'), and explicitly excludes the 'AI-edited sermon section', which differentiates it from sibling tools like get_sermon. The title reinforces a page-level read rather than a composite sermon object.

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 states the access condition (ended/interrupted public sessions), tells the agent to follow next_cursor with the same session_id until null, and to retrieve only needed pages due to the listing budget. It does not name a sibling alternative like get_sermon explicitly, but 'not the AI-edited sermon section' signals the exclusion clearly enough.

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