testpass_save_pack

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

No annotations are provided, so the description carries full burden. It reveals the tool creates or updates, but lacks details on side effects, permissions, idempotency, or constraints on the pack_id format or YAML size. More behavioral context is needed.

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 two sentences with no wasted words. It front-loads the core purpose and adds the create/update behavior concisely. Excellent structure for a simple tool.

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?

For a simple CRUD tool with two parameters and no output schema, the description covers basic purpose and behavior. However, it lacks usage guidance and behavioral details (e.g., merge vs overwrite, return value hints), making it adequate but not fully complete.

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% with descriptions for pack_id and yaml. The tool description echoes that pack_id identifies the pack and yaml is the definition, but adds no new meaning beyond the schema. Baseline of 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 clearly states 'Save a TestPass pack YAML definition for the caller' and specifies 'Creates or updates the pack identified by pack_id.' This accurately describes the verb (save) and resource (pack definition), and distinguishes it from siblings like testpass_edit_item which edits items within a pack.

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?

The description provides no guidance on when to use this tool versus alternatives like testpass_edit_item or testpass_run. It does not mention prerequisites, exclusions, or context where this tool should or should not be used.

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