splunk_update_index_settings

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

With no annotations, the description carries the full behavioral burden. It discloses that this is a write-mode mutation and can disable/enable an index, but it does not warn about operational impact such as ingestion disruption when disabling an index or data freezing/deletion when reducing retention.

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 purpose is front-loaded in the first sentence, with parameters listed compactly afterward. The Args list is useful and not padded, though the formatting is slightly verbose rather than maximally concise.

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?

An output schema exists, so return values need not be explained. For a mutation tool with no annotations, the description should provide more about side effects and prerequisites; it does give write mode and all parameter meanings, which is minimally adequate but leaves operational impact gaps.

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 description coverage is 0%, so the description must compensate, and it does: all four parameters are named and given meaning, including units for max_size_mb and frozen_retention_days. It could still clarify optional/default behavior, but it adds substantial value beyond the schema titles.

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 states a specific verb and resource: update settings, quotas, or disable/enable an index. It is clearly distinct from sibling tools like splunk_create_index and splunk_get_index, though it does not explicitly name alternatives.

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?

It gives a useful prerequisite, '(requires write mode)', which implies this is a mutation tool. However, it does not say when to use this rather than splunk_create_index, splunk_get_index, or splunk_list_indexes, nor does it describe when not to use it.

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