set_replay_saved

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

No annotations are provided, so the description carries the full behavioral burden. It says this mutates saved state but does not disclose permissions, reversibility, side effects, or response behavior, leaving important mutation details unexplained.

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 single sentence is front-loaded, efficient, and free of filler. Its terseness contributes to the completeness gaps, but as a conciseness measure it is strong.

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 mutation tool with four parameters, no annotations, no output schema, and zero schema description coverage, the description is under-specified. It does not explain required identifiers, mutation behavior, or what the agent should expect after saving or unsaving.

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 0%, so the description needs to compensate. It only clarifies that name is used when saving, while websiteId, replayId, and isSaved are left to schema names and types without added semantic or format guidance.

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 clear verb pair (save/unsave) and resource (session replay), so an agent can distinguish it from read-oriented siblings like get_replay_saved_status and list_saved_replays. It stops short of explicitly naming or contrasting those siblings.

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?

There is no explicit when-to-use guidance or mention of alternatives. The parenthetical about name only covers a parameter condition, not selection criteria relative to get_replay_saved_status or list_saved_replays.

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