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

With no annotations, the description carries the full burden, and it does disclose two meaningful behaviors: encryption at rest and deduplication. However, it omits important behavioral details such as whether duplicates are rejected or silently ignored, whether the operation is idempotent, what auth is required, and what happens on success or failure. The disclosure is useful but incomplete for a mutation-style 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, compact sentence that front-loads the primary action and resource, then adds two high-value behavioral details in parentheses. Every phrase earns its place with no redundant or filler content.

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 tool with no annotations and no output schema, the description leaves significant gaps: it does not explain the workflow around flag candidates, whether this affects challenge state, or what response the caller should expect. It also does not clarify how this relates to claim_challenge or list_flags. The core action is clear, but the surrounding context is under-specified.

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?

The schema already provides descriptions for value and source, and a UUID format/pattern for challenge_id, covering 67% of parameters. The description adds no parameter-specific semantics, such as explaining that 'value' is the raw flag string or that 'source' is optional context. This is acceptable but not exceptional given the schema's existing coverage.

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 uses a specific verb ('Store') and resource ('a flag candidate for a challenge'), making the tool's core purpose clear. It also adds two distinguishing operational details—encrypted at rest and deduplicated—that separate it from read-only siblings like list_flags. However, it does not explicitly contrast it with any sibling tool, so it stops short of full differentiation.

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. It does not mention that this is for storing a candidate before final submission, nor does it route users to list_flags or claim_challenge for related operations. Usage context is entirely implied by the tool's name and schema.

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