TDQS

B3.4/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds no behavioral context beyond the read itself — no mention of pagination/part mechanics, response size, or that omitted parts may require follow-up calls, even though the schema hints at multi-part delivery.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with the verb and resource first and the enumeration trailing. Slightly weakened by the open-ended "etc." and by duplicating content the schema already enumerates more completely.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a three-parameter, read-only fetch tool with full schema coverage and clear annotations, the description is adequate but thin: it omits the multi-part retrieval behavior and the section-filtering workflow that materially change how an agent should call it. Not misleading, just incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with the full canonical filename list, part indexing, and section-filter syntax all documented in the schema, so the baseline is 3. The description's category list partially overlaps that same name documentation and adds no new semantics for `part` or `section`.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource: "Read a canon file," then enumerates concrete document categories (invariants, anti-patterns, framework-matrix, troubleshooting, etc.) so an agent knows the domain of retrievable content. It does not explicitly contrast with sibling tools like tide_list or tide_gaps, so it stops short of a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied: the enumerated categories suggest 'call this when you need reference documentation on X,' but there is no explicit when-to-use, when-not-to-use, or alternative routing (e.g., vs. tide_list or tide_playbook). The genuinely useful routing tip ("use section when another document points you at one entry") lives in the schema, not the description.

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