policy

Read or set an initiative's sharing rules and allowed clouds independently. Pass an empty clouds list to remove the cloud restriction.

Instructions

Read or set sharing policy and allowed clouds independently. Empty clouds explicitly removes the restriction.

Removed value: -"Restrict this initiative to named clouds — comma or space separated.\n`policy` says WHETHER an initiative may leave; this says WHERE TO. An\ninitiative with no list may go to any configured cloud, which is how\nevery initiative behaves until this is set. Pass an empty string to\nclear the restriction. Set independently of `policy`, so restricting\ndoes not re-open and re-opening does not un-restrict."

B3/5.0

Behavior3/5

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

The readOnlyHint=false annotation already signals that this tool can mutate state. The description adds useful behavioral context by saying empty clouds explicitly removes the restriction and that policy and clouds can be set independently, but it does not cover permissions, side effects, or the concurrency behavior referenced by expected_revision.

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 two short sentences with no wasted language, and the key read-or-set distinction is front-loaded. The empty-clouds caveat follows immediately where it is most useful.

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?

For a five-parameter mutation tool with only partial schema coverage and sparse annotations, the description omits important context such as the required initiative target, concurrency via expected_revision, and replay semantics via request_id. An output schema exists, so return values need not be described, but the invocation behavior is still under-specified.

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

Parameters2/5

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

Schema description coverage is only 40%, so the description needs to compensate for several parameters. It clarifies the empty-array behavior for clouds and implies policy values are independent, but does not explain initiative, request_id, or expected_revision, leaving much of the parameter semantics to the schema.

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

Purpose4/5

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

The description states a specific dual action, 'Read or set', on specific resources, 'sharing policy and allowed clouds'. It is clear what the tool operates on, though it does not explicitly differentiate itself from siblings such as share, unshare, or clouds.

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

Usage Guidelines2/5

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

The description says the tool can read or set policy and clouds independently, but gives no explicit guidance on when to choose this tool versus share, unshare, or clouds. Usage is implied rather than directed, with no exclusions or alternatives named.

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