Create a GifOS broadcast (link and invite details, no join)

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

With no annotations, the description carries the full load and does well: it discloses the side-effect profile (nothing is created live, no one joins, no messages sent) and that the host password is used only for this call and is never stored, logged, or returned. It stops short of covering re-invocation behavior (e.g., whether calling twice mints two broadcasts), which matters for a creation 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?

Front-loaded with the mint action and return payload, then the non-effects, then the stream flag, then the password caveat. Dense and mostly efficient, though the host password guarantee is stated twice (body and again at the end), which is slight redundancy.

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?

No output schema exists, and the description compensates by enumerating the returned payload (title, times with time zone, link, Visit link, description, access details, roles) and its dual form as fields and ready-to-send text. Combined with the effect and credential disclosures, an agent has everything needed to call it correctly.

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 100%, so every parameter is already documented in the input schema, making 3 the baseline. The description adds a little context on the stream flag ('Stream to friends broadcast') and reiterates the host_password handling, but largely repeats what the schema descriptions already state.

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 and resource ('Mints a GifOS broadcast') followed by exactly what it returns: watch link plus invite fields and ready-to-send text. It also distinguishes itself from siblings by asserting 'Nothing goes live, nothing joins and nothing is sent', separating it from go_live, join_broadcast, and send_chat.

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 exclusions ('nothing goes live, nothing joins, nothing is sent') effectively route the agent away from go_live/join_broadcast toward this tool when it only wants to mint an invite. However, it never names a sibling explicitly or says 'use this when you only need the link and invite', so the guidance is inferential rather than stated.

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