save_release_radar

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

With no annotations provided, this description carries the full burden and delivers richly. It openly discloses the create-or-overwrite behavior, resolution strategy ('/me/playlists exact match first, falling back to search'), the unverified status of fallback matches, dry_run preview semantics, idempotency, and the echo of source identity. This is exemplary behavioral disclosure.

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 description is packed into three sentences, each carrying unique information: operation and overwrite semantics, resolution algorithm and dry_run/idempotency, and result echo. No wasted words, every phrase is informative, and the most important behavior (archive/overwrite) 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?

The description covers operation semantics, resolution path, safety via dry_run, idempotency, and output echo. With 3 optional params, full schema coverage, and no output schema, there is no missing critical information. The only minor gap is not explicitly describing the default archive_name behavior as 'Release Radar Archive', but this is available in the schema; overall this is complete enough.

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 the baseline is 3. The description adds meaning beyond the schema by explaining the overall resolution algorithm and that archive_name is 'created if missing, overwritten if present,' which reinforces the create/overwrite semantics. dry_run is contextually enriched with 'preview' and 'validate inputs' in the description. Slight gap: response_format behavior beyond schema enum labels isn't detailed in the description, but the schema already has clear descriptions.

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 verb ('Archive') and resource ('your Release Radar'), and uniquely distinguishes this tool from siblings like save_discover_weekly or create_playlist by clarifying it creates or overwrites an archive playlist. It also explains how Release Radar is resolved, which fully disambiguates the operation.

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 description implies usage context: it should be used when the user wants to save their Release Radar playlist to an archive, and it mentions dry_run for preview and idempotency when the archive already matches. It doesn't explicitly name sibling alternatives or state when not to use it, but the context is clear enough.

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