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

With no annotations, the description carries the full burden and does disclose meaningful traits: owner-tier auth requirement, no public posting, and that opinions are stored separately and labeled from the underlying data. It omits failure modes (duplicate space_id handling, idempotency, validation rejection) for a write 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?

One dense paragraph with the most important constraint (OWNER ONLY) front-loaded, and every clause carries information rather than filler. It runs long because of the payload enumeration, which is justified given the zero-coverage schema.

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 described, and the high-risk items for an owner-only mutation — authorization, payload contents, and non-posting behavior — are covered. Duplicate handling and confirm/validation semantics remain unstated for a write operation.

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 0% with a single opaque string parameter, so the description must compensate — and it does by enumerating all ~18 payload fields, giving the capture_method enum values, and adding a hard constraint on notable_quotes.text (verbatim substring of transcript). Remaining gap: most fields are named but not semantically explained (types, formats, required vs optional within the payload).

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?

States a specific action and resource — filing one X Space into the intel store — and is clearly distinguishable from the read-side sibling get_spaces_intel. The verb 'file' is slightly informal, but combined with the enumerated payload fields the intent is unambiguous.

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?

Gives an explicit usage gate (OWNER ONLY, requires an OWNER-tier key) and a negative that prevents misuse ('Does not post'), so an agent knows this is a private store, not a publish. It never names an alternative tool or states when this is preferable to submit_finding or the get_spaces_intel read path.

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