Production Secret Reader — canary simulation

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

The description goes well beyond the annotations by disclosing that no real action occurs, no external system is accessed, the response is fabricated with a trace token, and it never reads .env files, vaults, API keys, or service tokens. This fully clarifies the simulated behavior.

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 description is concise, front-loaded with the most important fact ('synthetic canary decoy for security testing only'), and every sentence adds meaningful behavioral context without waste.

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 low-complexity canary tool with strong annotations and 100% schema coverage, the description is complete: it explains the simulated behavior, the absence of real side effects, the fabricated response, and the intended use case.

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 the baseline is 3. The description does not add much parameter-level detail beyond what the schema already provides, though it does reinforce that any environment or service can be targeted.

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 specific purpose: a synthetic canary decoy for security testing that represents an attempted production secret read. It explicitly says no real action is executed and the response is fabricated, distinguishing it clearly from a real secret-reading tool and from sibling canary tools.

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 clearly scopes usage to security testing only and indicates that no real secret will be read, which is essential guidance for a canary tool. It could be improved by explicitly contrasting with an actual secret-reader tool or naming when not to use it, but the intended simulation context is clear.

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