What is a Tool?
A Tool in Flowyble is a multi-step workflow automation. Unlike agents (which reason freely), tools follow a predefined sequence of steps — each step executes a specific function with configured parameters. Tools are:- Deterministic — same input produces the same sequence of operations
- Composable — chain multiple functions into complex workflows
- Reusable — run manually, via API, or triggered by webhooks
- Shareable — publish to the marketplace as templates
Tool vs Agent
| Feature | Tool | Agent |
|---|---|---|
| Execution | Sequential steps | LLM-driven loop |
| Flexibility | Fixed workflow | Dynamic reasoning |
| Predictability | High | Variable |
| Token cost | Only if steps use LLM | Every iteration uses LLM |
| Best for | Repeatable automations | Open-ended tasks |
Tool structure
A tool consists of:- Name & Description — identification
- Parameters — input configuration (JSON)
- Steps — ordered list of function calls
- Output Schema — expected output format (optional)
- Which function to call
- Input mapping — how to pass data from parameters or previous step outputs
- Output handling — how to process the result
Running tools
Tools can be executed:- Dashboard — manual execution from the tool detail page
- API —
POST /v1/tools/run/{toolId}with optional input JSON - Webhook — external systems trigger execution via HTTP
- Agent — an agent can call a tool as part of its reasoning
