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

Adds substantial context beyond the annotations: released:true publishes and cannot be undone through this connector, confirm:true is mandatory, employeeID:null creates an unassigned shift, and there is no automatic retry. These are important operational facts for a destructive, non-idempotent mutation that the annotations alone do not convey.

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 four dense sentences with no filler. Safety-critical constraints and prerequisite conditions are front-loaded, and every sentence adds actionable information.

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 complex destructive create operation with no output schema and low schema coverage, the description covers prerequisites, irreversibility, retry behavior, and unassigned-shift behavior well. It is slightly incomplete regarding time format and comment/tag semantics, but overall gives an agent enough to act safely.

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 low (13%), and the description only clarifies three of eight parameters: confirm, released, and employeeID. It does not explain start/end formats, comment semantics, or tagIDs behavior, so meaningful gaps remain despite useful flag explanations.

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?

States a specific verb and resource ('Create one shift') and scopes it to a single shift after exact staff, role, and times are approved. This clearly distinguishes it from sibling tools like workfeed_update_shift and the various read/list tools without ambiguity.

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?

Provides a clear precondition: the user must approve the exact staff, role, and times before calling. It also gives handling guidance for uncertain outcomes ('inspect before retrying'), though it does not explicitly name workfeed_update_shift as the alternative for modifying an existing shift.

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