replace_flow

Overwrite a Langflow workflow's entire content—name, description, data, and folder—by specifying its flow ID.

Instructions

Replace an entire flow (PUT) with new content. Overwrites name, description, data, and folder for the given flow ID.

Behavior2/5

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

No annotations exist, so description must convey behavioral traits. It mentions overwriting fields but lacks details on side effects, authorization needs, or behavior when optional parameters are omitted (e.g., will fields be cleared?).

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?

Two sentences, zero waste. The first sentence states the action and HTTP method; the second lists overwritten fields. Front-loaded and efficient.

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

Completeness3/5

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

With 5 parameters (including nested objects) and no output schema, the description is adequate for core purpose but fails to explain return values or the effect of omitting optional parameters.

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 coverage is 100%, so baseline is 3. Description adds context (PUT, overwrites) but does not significantly enhance parameter meaning beyond the schema descriptions.

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?

The description clearly states the tool replaces an entire flow using PUT, overwriting name, description, data, and folder. It uses specific verbs and resources, distinguishing it from sibling tools like update_flow (partial update).

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

Usage Guidelines3/5

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

The description implies usage for full replacement (PUT), but does not explicitly state when to use this vs. alternatives like update_flow, nor provides when-not-to-use guidance.

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