sr_list

List storage repositories (SRs) with capacity, physical usage, and virtual allocation. Filter by pool and limit results to manage XCP-ng storage.

Instructions

[READ] List SRs with capacity, physical usage, virtual allocation.

Returns {"srs": [...], "returned": N, "limit": L, "truncated": bool}.
When truncated is true there are more SRs than were returned.

Args:
    pool: Optional pool uuid to filter by.
    limit: Max SRs to return after filtering (default 200).
    target: Xen Orchestra target name from config; omit for the default.

Behavior4/5

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

No annotations provided, so description carries full burden. Clearly marks as read operation '[READ]', describes return format including truncation flag for pagination. No mention of authentication needs or performance, but sufficient for a read tool.

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?

Concise: one-line summary, return format, then args section. No wasted sentences, front-loaded with purpose.

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?

No output schema, but description details return format including 'returned', 'limit', 'truncated' fields. Covers all parameters. Complete for a simple list tool.

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

Parameters5/5

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

Schema description coverage is 0%, but description explains all three parameters: pool (optional UUID filter), limit (max results, default 200), target (optional config name). Each parameter's purpose and default are clear.

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?

Starts with '[READ] List SRs with capacity, physical usage, virtual allocation.' Clearly states verb (list) and resource (SRs), and specifies included fields. Distinguishes from sibling tools like vm_list or sr_get.

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?

Does not explicitly state when to use vs. alternatives. Implied usage via parameter descriptions (optional pool filter, limit), but no when-not or alternative tool guidance.

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