feature_flag_system

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

No annotations are present, so the description carries the full burden. 'Set up' is opaque: it does not disclose side effects, generated files, auth requirements, or how the storage values (database/config/launchdarkly) change behavior. This is a significant gap for a setup/mutation tool.

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 a single front-loaded sentence with no filler, which is structurally efficient. It sacrifices necessary detail, but that is a completeness concern rather than a conciseness one.

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?

With four parameters, no annotations, no output schema, and a nested feature definition, the description is too thin. It omits behavior, output, prerequisites, backend semantics, and how user/percentage gating is expressed in the schema.

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 only 50%, so the description should compensate for undocumented parameters, but it does not explain api_key, storage, or cache_ttl_seconds. Worse, it claims gating 'by plan, user, or percentage rollout' while the features schema only accepts name and plans, making the user/percentage modes unrepresentable.

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 the action and resource: 'Set up a feature flag system' and adds the gating purpose 'by plan, user, or percentage rollout.' It is not a tautology, but it does not distinguish itself from the sibling flag_setup_system.

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 'for gating features by plan, user, or percentage rollout' clause implies a use case, but there is no explicit when-to-use guidance or mention of alternatives such as flag_setup_system or flag_ab_test_setup. The agent must infer when this tool is the right choice.

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