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

Discloses the non-obvious truth that this 'get' call mutates state and is not idempotent, consistent with the annotations, and warns that callers must poll. It also explains link semantics (absolute signed URLs with no login required), link expiry, the extra 'tiles' stage for sheet packs, and what the tiles array contains. This goes well past what the annotations convey.

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?

Dense and mostly earning its place, but the lead is the auth/setup sentence and URL rather than the core action, so the key behavior ('advances the pack and reports status') arrives third. Long, but almost every sentence carries operational information.

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 takes responsibility for return semantics: designPackage.status/imageUrl, designApproved, per-scene status, tiles array fields, and the complete flag. Combined with the polling loop instructions and auth prerequisite, an agent has everything needed to call it correctly in a loop.

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 single parameter has 100% schema description coverage, so the schema already carries the meaning. The description adds the provenance note that projectId comes from create_design_sheet or create_overlay_pack, which is slightly beyond schema text but nothing more is needed for a one-parameter tool.

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 behavior: running ~15 seconds of rendering work and returning pack/scene status, including designPackage and tiles detail. It is far more than a restatement of the name. It does not, however, differentiate itself from closely-named siblings such as get_alert_pack_status, get_render_status, or get_style_sheet_character_edit_status, so an agent cannot fully infer which status tool applies to which pack family.

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 concrete operating instructions: call repeatedly every few seconds until `complete` is true, and poll a design-sheet-only project until designPackage.status is 'ready' before calling approve_design_sheet. The prerequisite (approved AlertForge account connection, OAuth flow) is also spelled out. What is missing is routing guidance versus the sibling status tools.

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