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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, so the safety profile is covered; the description then adds genuinely new behavioral facts: it reflects live constants, it discloses no specific manager's private standing, and it distinguishes ENFORCED brakes (freeze-at-dispatch, ladder) from mere DETECTION that escalates to a human. That enforced-vs-detected distinction is substantive context an agent could not get from the annotations.

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 purpose is front-loaded, but the body is a dense run-on stack of jargon-laden clauses and internal ticket references ('CO 694', 'CO 295') that add noise rather than decision value. The trailing 'Example: call federation_governance with arguments {}.' is redundant for a no-argument tool and could be cut without loss.

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 carries the burden of describing the return value, and it discharges that well by enumerating the governance-model object's fields (ladder levels and rank ordering, clamps with worked example, thresholds, standing states, detection ceilings, accountability statement). What it omits is how to act on those fields, but for an informational read tool the coverage is close to complete.

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?

The tool takes zero parameters, so the baseline of 4 applies; the description correctly shows the call shape as an empty argument object. There is nothing further for the description to disambiguate on the input side.

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 opening clause states the resource precisely: 'How the federation governs its agents', followed by an enumerated model (autonomy ladder, manager ceiling, override clamp, thresholds, enforcement). The purpose is unmistakable, but it never names which sibling it differs from (federation_why, federation_help, about_us_about), so an agent must infer that this is the governance-model explainer rather than a generic help tool.

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?

It gives one strong usage cue: 'Verify against the live tools rather than taking it on trust', which signals this is documentation to be cross-checked, not an operational source of truth. However, there is no explicit when-to-use or when-not-to-use versus the many sibling explainer tools, so the routing decision is left implicit.

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