TDQS

A3.8/5.0
Behavior3/5

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

With no annotations, the description carries full burden. It states it reads log_entries and returns a markdown summary, suggesting a read-only operation. However, it does not disclose potential side effects, prerequisites (e.g., session existence), or limits (e.g., entry count). Adequate but not detailed.

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

Conciseness5/5

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

The description is concise: a clear headline sentence, a brief explanation, and a command equivalence. Every sentence adds value without redundancy.

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

Completeness4/5

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

Given the tool's simplicity (single param, read-only), the description covers the core purpose and output format (markdown). It could mention if it only reads from the provided session or has size limits, but overall it is fairly complete for a straightforward tool.

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?

The schema has 0% description coverage, so the description must add meaning. It mentions 'Equivalent to /summary: [session name] command', which hints that session_name is the session's name. This provides some context beyond the bare schema, but still lacks format details or examples.

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

Purpose5/5

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

The description clearly states the tool generates a 'paste-ready context block for new chats' by reading log entries and returning a formatted markdown summary. This distinguishes it from siblings like marm_log_show (raw logs) and marm_log_entry (adding entries).

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?

The description implies usage by equating to a /summary command, indicating it should be used to get a compact summary. However, it does not explicitly state when to use vs. alternatives like marm_log_show or marm_smart_recall, nor provide when-not-to-use guidance.

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