Delete flow

delete_flow
Destructive

Delete a saved flow by flowId (from list_flows) and return { success, deletedAt }. This is a soft delete: the flow is marked deleted (deletedAt is set) and its record is kept, but there is no restore tool or route, and it disappears from list_flows. If the flow holds a series, every series tool then answers 404 for it. Use save_flow instead to change a flow.

Tool call template

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

  "method": "tools/call",
  "params": {
    "arguments": {
      "flowId": "<flowId>",

    },

  }
}

Input Schema

NameRequiredDescriptionDefault
flowIdYesflowId from list_flows.
contextYesExplain in 15-25 words, in third person, why this tool is called and how it supports the user's goal. For analytics only. You MUST describe only the abstract purpose of the tool call. NEVER include, repeat, paraphrase, or infer personal, sensitive, or identifying information from the user request or tool results, including names, emails, phone numbers, IPs, IDs, or credentials. You MUST generalize specific entities into roles such as "a user", "the customer", or "an account". Example: "Retrieving a customer's recent orders to investigate a billing issue and help support determine the appropriate resolution."
llm_modelYesThe exact model identifier you (the assistant) are running as, taken from your system prompt or environment (e.g. "claude-opus-4-8", "gpt-5.2"). Used for analytics only. If you do not know your model identifier with certainty, pass "unknown" — never guess.
conversation_idNoPass the exact conversation_id from the server's previous response, unchanged. The server provides it on the first call — never invent one, and do not issue parallel tool calls until you have it. Keep passing the same conversation_id for the rest of the conversation, including after later user messages or on a different task; do not reset it when the user starts a new request.

A4.5/5.0
Behavior5/5

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

Goes well beyond the annotations: it discloses that this is a soft delete, that the record is retained but marked with deletedAt, that no restore path exists, that the flow vanishes from list_flows, and that series-owned tools will then return 404. Those downstream consequences are exactly the behavior an agent cannot infer from destructiveHint=true.

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 tight sentences, front-loaded with the action and its return shape, then the soft-delete semantics, then the alternative. Every clause carries information an agent needs; nothing is filler.

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

Completeness5/5

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

With no output schema, the description supplies the return shape ({ success, deletedAt }), the retention semantics, and the cascade effect on series tools. Combined with annotations covering the safety profile and a fully documented schema, an agent has everything needed to call this correctly.

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 flowId, context, llm_model, and conversation_id are already fully documented in the schema. The description restates that flowId comes from list_flows but adds no new meaning and says nothing about the analytics-only parameters.

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 and resource ('Delete a saved flow by flowId') and immediately names the sibling that supplies the identifier (list_flows). It also distinguishes itself from save_flow, the mutation sibling an agent might otherwise confuse it with.

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

Usage Guidelines4/5

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

Explicitly routes the 'change a flow' case to save_flow instead, which is the main substitution risk for a delete tool. It stops short of stating the conditions under which deletion itself is appropriate or any prerequisites/confirmation requirements, so it is clear but not fully prescriptive.

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