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

With no annotations, the description carries the full behavioral burden and delivers: 3-update cap, non-destructive versioning (current version stays until new one is ready), re-record vs re-render semantics for different change types, a 10% length constraint, and that it spends no minutes. This is exactly the beyond-structured-fields context an agent needs.

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?

Front-loads the core action and drops constraints in a dense, mostly sentence-per-idea block with no filler. It is somewhat long and has a slightly run-on opener ('as the editor under the podcast on the site does'), but nearly every clause conveys a distinct operational fact.

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 complex, high-parameter mutation tool with no output schema and no annotations, the description covers the safety, cost, versioning, and limits an agent must know before calling. Nothing essential to correct invocation is missing.

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 67%, and the description reinforces the parameter groups by mapping edit intents to fields ('rewrite, delete or reassign script lines' → line_changes, 'either host's voice or name' → host_*_voice/name, 'captions, sound bar or studio picture'). It adds contextual meaning but does not detail individual optional params beyond what the schema already documents.

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 verb+resource ('Change a FINISHED Animated Podcast') and enumerates what can be edited (script lines, host voice/name, captions, sound bar, studio picture), which cleanly separates it from siblings like create_podcast, get_podcast, and preview_podcast_studio. An agent can identify the tool without opening the schema.

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 clear preconditions ('FINISHED' podcast, up to 3 updates, agree exact changes first and call once) that direct when and how to invoke it. It implies but never names alternatives or explicitly states when not to use it (e.g., use get_podcast to read first, create_podcast for new ones), so it stops short of full routing guidance.

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