Agent Resilience & Networking MCP

resilient_cookie_jar_session_sync

Sync cross-domain cookie sessions for agents and scraping pipelines by managing RFC-6265 tokens, SameSite policies, expiration, and proxy synchronization.

Instructions

B3.3/5.0

Behavior2/5

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

No annotations are provided, so the description must fully disclose behavior. It describes the scope of management (cross-domain, SameSite, expiration, proxy sync) but does not disclose whether the tool mutates state, requires authentication, has side effects, or what it returns. The mention of a price suggests a payment requirement but does not explain the payment flow. The description is insufficient for a complex engine.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that front-loads the main purpose. The parenthetical price adds operational context but could be seen as extraneous. Overall, it is concise and readable, though slightly unstructured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity of a cookie jar engine with multiple responsibilities and no output schema or annotations, the description is incomplete. It does not explain what the tool returns, how to structure the payload, or any prerequisites or side effects. An agent would have to guess many details.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema already documents both parameters (payload and paymentSignature) with clear descriptions. The tool description does not add any additional semantics beyond what is in the schema, such as payload format or expected structure. Since schema coverage is 100%, the description adds no extra value here.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's function: an RFC-6265 compliant cookie jar engine that manages cross-domain session tokens, SameSite policies, expiration schedules, and proxy synchronization. It is specific and distinct from sibling tools, none of which deal with cookie management.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description does not explicitly state when to use this tool or when to prefer an alternative. It implies usage for cookie and session management, but does not provide exclusions or alternatives. Since no sibling is similar, the guidance is minimal but not misleading.

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