publish_sessionFreeze the current music into a new immutable session and return its URL. The source session stays editable at its own URL. Only call this when someone explicitly asks to publish; it is never a side effect of editing or exporting.
| Name | Required | Description | Default |
|---|---|---|---|
| session_id | Yes | The UUID after /s/ in a Keyboardia share URL. Pass only the UUID, not the full URL. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds valuable behavioral context beyond the annotations: it explains the resulting session is immutable, the source remains editable, and a URL is returned. This complements the annotated hints (e.g., destructiveHint=false aligns with 'source session stays editable'). No contradictions found.
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?
Two concise sentences with no wasted words. The first sentence states the action and result, the second clarifies the non-destructive nature and usage guard. Information is front-loaded.
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?
Given the tool's simplicity (one parameter, no output schema) and the strong annotations, the description covers purpose, behavior, return value, and usage guard. It is fully sufficient for an agent to invoke the tool 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 description coverage is 100% for the single parameter, including the instruction to pass only the UUID and not the full URL. The description adds no additional parameter details, so the baseline 3 applies.
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 uses a specific verb ('freeze') and clearly states the resource ('current music') and outcome ('new immutable session and return its URL'). It distinguishes this from sibling tools by noting the source session stays editable, making it distinct from edit_session or export_midi.
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?
Explicitly states when to call ('only when someone explicitly asks to publish') and when not to ('never a side effect of editing or exporting'). This provides clear boundaries and prevents unintended use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool targets a distinct action: analyze, create, edit, export, get, publish, and remix. Even similar actions like create versus publish are clearly separated by whether the result is editable or immutable.
All tool names follow a consistent verb_noun pattern with clear, domain-appropriate verbs (analyze, create, edit, export, get, publish, remix). The naming is uniform and predictable.
Seven tools is well-scoped for the session lifecycle: create, read, edit, export, publish, remix, and analyze. There are no redundant tools and the count feels appropriate for the domain.
The tool set covers the core session lifecycle well, including editing, publishing, remixing, and exporting. A minor gap is the lack of a delete or list operation, but these may be handled outside the server or are not essential for the intended workflow.
