withdraw_invitation

DestructiveIdempotent

Withdraw a pending sent connection request. Use to cancel a pending sent invitation (from list_sent_invitations), for example one older than three weeks. Not for received invitations, see decline_invitation.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {
      "account_id": "<account_id>",
      "linkedin_id_or_url": "<linkedin_id_or_url>"
    },
    "name": "withdraw_invitation"
  }
}

Input Schema

Name	Required	Description
`account_id`	Yes	Reach id of the LinkedIn account to act on, from list_accounts.
`idempotency_key`	No	Optional. A key you choose (a UUID is fine) that names this exact call. If you retry with the same key and the same arguments, the first call's result is returned and nothing is done twice on LinkedIn. Reusing a key with different arguments is refused. Keys expire after 24 hours.
`linkedin_id_or_url`	Yes	The LinkedIn member: profile URL, vanity name (the part after /in/), Sales Navigator URL, or internal member id.

Output Schema

Name	Required	Description	Default
`withdrawn`	No

TDQS

A4.2/5.0

Behavior3/5

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

Annotations already declare destructiveHint=true, idempotentHint=true, openWorldHint=true and readOnlyHint=false, covering the safety profile. The description adds only the constraint that the target must be pending, but says nothing about reversibility, failure modes, or quota cost. With annotations carrying the burden, this is a modest but acceptable addition.

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?

Three short sentences, front-loaded with the core action, then usage context, then the exclusion. Every sentence earns its place with no filler.

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

Completeness4/5

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

An output schema exists, so return values need not be described, and the annotations plus schema cover arguments and safety. The description supplies the key routing information; only failure/precondition detail is absent.

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

Parameters3/5

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

Schema description coverage is 100%, so account_id, linkedin_id_or_url and idempotency_key are fully documented in the schema. The description adds no parameter-level detail beyond what is already structured, which matches the baseline 3.

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?

States a specific verb (withdraw) and resource (a pending sent connection request), and explicitly delineates it from the sibling decline_invitation. An agent can pick this over the other invitation tools without opening a schema.

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

Usage Guidelines5/5

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

Gives the when ('cancel a pending sent invitation from list_sent_invitations, e.g. older than three weeks'), the when-not ('Not for received invitations'), and the named alternative ('see decline_invitation'). Routing is fully specified.

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