NULL — the complete agent handbook (do everything, correctly)

null_agent_guide

One read that teaches an agent to use every NULL capability with the right privacy posture: create an identity, seal + send + scan, start forward-secret sessions, drop an anonymous tip, check a Legacy heartbeat, make/detect stealth payments, and what each action reveals to whom. All crypto is local (SDK at /svc/msg2-sdk.mjs; browser bundle /svc/anygas-web.js); this MCP only relays sealed/signed material. Read-only, static knowledge.

Tool call template

A4.7/5.0
Behavior5/5

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

With no annotations provided, the description carries full behavioral disclosure and does so well: it states the tool is read-only, static knowledge, that all crypto is local, gives exact SDK/browser bundle paths, and clarifies that the MCP only relays sealed/signed material. This gives an agent a complete safety and privacy picture with no assumptions left to infer.

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

Conciseness5/5

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

The description is front-loaded with its purpose and uses a compact, concrete list of covered capabilities, followed by security-critical context and a clear read-only/static label. Every sentence adds distinct value, and none merely restates the title.

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

Completeness5/5

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

For a zero-parameter static guide with no output schema, the description is complete: it covers purpose, covered capabilities, privacy posture, local-crypto implementation, and behavioral boundaries. An agent can safely decide to invoke this tool without needing additional context from elsewhere.

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

Parameters4/5

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

The tool has zero parameters, so the baseline is 4. The description adds useful non-parameter context like SDK paths and relay behavior, but there are no parameters for it to document.

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 uses a specific verb/resource ('teaches an agent to use every NULL capability') and enumerates concrete covered actions: identity creation, sealed sends, forward-secret sessions, anonymous tips, and stealth payments. It unambiguously labels itself as 'read-only, static knowledge,' which distinguishes it from sibling operation tools.

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

Usage Guidelines4/5

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

The description presents itself as the 'complete agent handbook' and a 'one read' that teaches proper use of all NULL capabilities, making it clear this is the starting reference. It does not explicitly name alternatives or exclusions, but its read-only/static framing separates it from the many sibling action tools without needing further explanation.

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