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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so safety is covered. The description adds real value by disclosing the shape of the output (numbered steps with times, element selectors, typing, navigation), but says nothing about volume, pagination, or failure modes for an invalid/unshared link.

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?

One compact sentence that front-loads the core concept ('numbered steps to reproduce') and then enumerates contents. Slightly awkward as a colon-delimited fragment, but there is no wasted text.

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?

With no output schema, the description must convey the return value, and it partially does by listing the kinds of events captured. It omits structure (flat list vs grouped sessions), size/limits, and how it relates to sibling read tools, leaving the agent short of what a 1-param inspection tool needs.

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% and the single 'recording' parameter is fully documented in the schema, including accepted URL forms and id fallback. The description adds nothing about the parameter, 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 explains what 'steps' means (clicks with element text and selectors, typing, navigation, timestamps) and frames it as a reproduction guide. However, it is a noun-phrase fragment with no verb, and it never distinguishes this from siblings like get_guide, get_frames, or get_transcript that plausibly return overlapping content.

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?

No guidance on when to choose get_steps over get_guide, get_frames, get_transcript, or get_annotations, nor any prerequisites (e.g., must call open_recording first). The agent must infer usage from the name alone.

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