Memory snippet for agents

memory_snippet
Read-only

Retrieves a static note explaining when ToolSnap tools fit a task and how to save it in your agent runtime's memory per harness. Saves nothing; read-only.

Instructions

Free, read-only. Returns static text: a short note on when ToolSnap tools suit a task, plus how to store a note in your runtime's memory. This tool saves nothing. Use only if your user asks about persistent memory or ToolSnap setup; show them the text and save it only with their approval.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {},
    "name": "memory_snippet"
  }

TDQS

A4.7/5.0
Behavior5/5

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

Annotations already declare readOnlyHint=true and openWorldHint=false, and the description reinforces this with 'Free, read-only' and 'This tool saves nothing.' It also discloses the human-approval requirement before persisting anything, which annotations cannot express.

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?

Three tight sentences: cost/safety first, then what it returns, then usage guidance. Every clause carries a decision-relevant fact, with nothing padded.

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

Completeness5/5

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

With no output schema, the description correctly summarizes the return value ('static text' with a note and save instructions) and covers the side-effect and approval model. Nothing needed to invoke it correctly is missing.

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 coverage is 100% and the single 'harness' parameter is fully documented in the schema, including enum values. The description never mentions the harness parameter or why one would omit it, so it adds no meaning beyond the schema. Baseline 3 applies.

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?

States a specific verb and resource: returns static text containing a note on when ToolSnap tools fit and how to save it in the runtime's memory. This is clearly distinguishable from siblings like tool_catalog, use_tool, and task_recipes, which do other things.

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

Usage Guidelines5/5

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

Explicitly says when to use it ('only if your user asks about persistent memory or ToolSnap setup') and adds the operating instructions: show the user the text, save only with approval. No inference required.

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