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

Beyond the annotations (readOnlyHint=false, openWorldHint=true, destructiveHint=false), the description discloses idempotency behavior ('a repeat returns already_filed'), a preview/side-effect-free mode, a real data-exposure warning that public_repository=true makes tickets visible to anyone, and a full error taxonomy with retry semantics for ambiguous outcomes. This is exactly the behavioral context an agent needs before triggering an external write.

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 core action, routing rule, and batch limit are front-loaded in the first sentence, and the dry_run/public_repository warnings follow immediately. The 18-item error-code enumeration is bulky, but it is material rather than filler, since it underpins the retry guidance that follows.

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 no output schema, the description carries the return-value burden and does so for the notable paths (already_filed repeat, dry_run ticket payload) plus error outcomes. It omits what a successful filed response contains and any permission/role prerequisites, though the permission_missing/role_missing error codes partially signal those.

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 only 33% (only `destination` is documented in-schema), so the description has to compensate, and it largely does: it defines dry_run's semantics ('returns the exact tickets without sending'), the 1-50 cardinality of threat_entry_ids, and `destination` as a route override. It stops short of clarifying the nested destination fields (provider, channel_ref, destination) or the id type/format expected in threat_entry_ids.

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 names a specific verb and resource ('Send 1-50 threat report entries to the tracker') plus the routing mechanism (route or `destination`), so the agent knows exactly what action is performed and against what. It does not, however, explicitly distinguish this filing tool from siblings like sync_threat_tickets or comment_threat_on_change, which an agent evaluating near-duplicate sending tools would want.

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 concrete operational guidance: batch range 1-50, use dry_run=true to preview without sending, one ticket per threat per report, and specific resend rules for ambiguous outcomes (do not resend filed_unrecorded/outcome_unknown; resend not_attempted). What is missing is any explicit statement of when to use this rather than sync_threat_tickets, or prerequisite permissions before invoking.

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