vibeside_restore_session_snapshot

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

With no annotations, the description carries the full behavioral burden. It usefully discloses that decryption happens (implying a passphrase may be required) and that storage is injected into the active page, but it omits key mutation semantics: whether existing cookies/storage are overwritten, whether the operation is reversible, and any auth/permission requirements.

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?

A single front-loaded sentence with no filler; the core action and target are stated immediately and nothing is wasted.

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 no annotations and no output schema, the description covers the core operation but leaves out side-effect semantics (overwrite behavior, failure modes) and any usage context. Schema richness compensates for parameter documentation, but behavioral completeness is only partially satisfied.

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%, so all five parameters (navigate, timeoutMs, passphrase, profileName, snapshotName) are already documented in the schema. The description's reference to 'decrypt' loosely maps to the passphrase parameter but adds no syntax or format detail beyond structured fields, so 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?

States a specific compound verb (decrypt and restore), the exact resource (cookies and web storage snapshot), and the target (active browser page). This clearly distinguishes it from siblings like save_session_snapshot and delete_session_snapshot, though it doesn't explicitly name those alternatives.

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 says what the tool does but gives no when-to-use guidance, no prerequisites, and no mention of alternatives such as import_session or list_session_snapshots. The agent must infer usage entirely from the verb.

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