Search Composio Tools
Tool Server Info: Composio connects 500+ apps—Slack, GitHub, Notion, Google Workspace (Gmail, Sheets, Drive, Calendar), Microsoft (Outlook, Teams), X/Twitter, Figma, Web Search / Deep research, Browser tool (scrape URLs, browser automation), Meta apps (Instagram, Meta Ads), TikTok, and more—for seamless cross-app automation. Use this tool to discover relevant tools plus the recommended plan and common pitfalls for reliable execution. Always call this tool first whenever a user mentions or implies an external app, service, or workflow—never say "I don't have access to X/Y app" before calling it. Usage guidelines: - Use this tool whenever kicking off a task. Re-run it when you need additional tools/plans due to missing details, errors, or a changed use case. - If the user pivots to a different use case in same chat, you MUST call this tool again with the new use case and generate a new session_id. - Specify the use_case with a normalized description of the problem, query, or task. Be clear and precise. Queries can be simple single-app actions or multiple linked queries for complex cross-app workflows. - Pass known_fields along with use_case as a string of key–value hints (for example, "channel_name: general") to help the search resolve missing details such as IDs. Splitting guidelines (Important): 1. Atomic queries: 1 query = 1 tool call. Include hidden prerequisites (e.g., add "get Linear issue" before "update Linear issue"). 2. Include app names: If user names a toolkit, include it in every sub query so intent stays scoped (e.g., "fetch Gmail emails", "reply to Gmail email"). 3. English input: Translate non-English prompts while preserving intent and identifiers. Example: User query: "send an email to John welcoming him and create a meeting invite for tomorrow" Search call: queries: [ {use_case: "send an email to someone", known_fields: "recipient_name: John"}, {use_case: "create a meeting invite", known_fields: "meeting_date: tomorrow"} ] Plan review checklist (Important): - The response includes a detailed execution plan and common pitfalls. You MUST review this plan carefully, adapt it to your current context, and generate your own final step-by-step plan before execution. Execute the steps in order to ensure reliable and accurate execution. Skipping or ignoring required steps can lead to unexpected failures. - Check the plan and pitfalls for input parameter nuances (required fields, IDs, formats, limits). Before executing any tool, you MUST review its COMPLETE input schema and provide STRICTLY schema-compliant arguments to avoid invalid-input errors. - Determine whether pagination is needed; if a response returns a pagination token and completeness is implied, paginate until exhaustion and do not return partial results. Response: - Tools & Input Schemas: The response lists toolkits (apps) and tools suitable for the task, along with their tool_slug, description, input schema / schemaRef, and related tools for prerequisites, alternatives, or next steps. - NOTE: Tools with schemaRef instead of input_schema require you to call COMPOSIO_GET_TOOL_SCHEMAS first to load their full input_schema before use. - Connection Info: If a toolkit has an active connection, the response includes it along with any available current user information. If no active connection exists, you MUST initiate a new connection via COMPOSIO_MANAGE_CONNECTIONS with the correct toolkit name. DO NOT execute any toolkit tool without an ACTIVE connection. - Time Info: The response includes the current UTC time for reference. You can reference UTC time from the response if needed. - The tools returned to you through this are to be called via COMPOSIO_MULTI_EXECUTE_TOOL. Ensure each tool execution specifies the correct tool_slug and arguments exactly as defined by the tool's input schema. - The response includes a memory parameter containing relevant information about the use case and the known fields that can be used to determine the flow of execution. Any user preferences in memory must be adhered to. SESSION: ALWAYS set this parameter, first for any workflow. Pass session: {generate_id: true} for new workflows OR session: {id: "EXISTING_ID"} to continue. ALWAYS use the returned session_id in ALL subsequent meta tool calls.
Why this helps
A useful request gets buried while you hunt through app catalogs and try to remember which integrations can do what.
- Find relevant Composio tools from the original request context.
- Surface prerequisites before work starts.
- Keep tool research attached to the conversation that prompted it.
Setup
Build it in a few focused steps.
- 1Connect Slack and Composio to Notis once in the portal.
- 2Create an automation in the portal and describe in plain language that channel requests for cross-app tasks should trigger a Composio tool search.
- 3Select Slack Channel Message Received as the trigger and choose a channel for run reports.
- 4Test with one real channel request that needs another app.
Questions about this workflow
Does this execute the requested task?
This workflow searches for relevant Composio tools and guidance. The prompt can specify whether Notis should only report the findings or continue with an approved next step.
Will it respond to direct messages?
No. This workflow uses the Slack channel message trigger, which does not match direct messages.

Supported Triggers and Actions
Notis builds workflows that link Slack to Composio. A trigger fires from one place; an action lands in another.
Slack triggers
Composio actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Ask Oracle
Static helper that returns a comprehensive system prompt describing how to plan and execute tasks using the available composio tools and workflows. no inputs required; simply call to retrieve the prompt. always call this after the search tool is executed -- it will provide the best context on how to proceed, chain tools, and execute the task end-to-end. relevant tools referenced by the prompt: 1. composio search tools 2. composio multi execute tool 3. composio execute code 4. composio manage connections 5. composio bash tool
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Check active connection (deprecated)
Deprecated: use check active connections instead for bulk operations. check active connection status for a toolkit or specific connected account id. returns connection details if active, or required parameters for establishing connection if none exists. active connections enable agent actions on the toolkit.
New Channel Created Trigger
Triggered when a new channel is created in Slack.
Check multiple active connections
Check active connection status for multiple toolkits or specific connected account ids. returns connection details if active, or required parameters for establishing connection if none exists. active connections enable agent actions on toolkits.
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Create Plan
This is a workflow builder that ensures the LLM produces a complete, step-by-step plan for any use case. WHEN TO CALL: - Call this tool based on COMPOSIO_SEARCH_TOOLS output. If search tools response indicates create_plan should be called and the usecase is not easy, call it. - Use this tool after COMPOSIO_SEARCH_TOOLS or COMPOSIO_MANAGE_CONNECTIONS to generate an execution plan for the user's use case. - USE for medium or hard tasks — skip it for easy ones. - If the user switches to a new use case in the same chat and COMPOSIO_SEARCH_TOOLS again instructs you to call the planner, you MUST call this tool again for that new use case. Memory Integration: - You can choose to add the memory received from the search tool into the known_fields parameter of the plan function to enhance planning with discovered relationships and information. Outputs a complete plan with sections such as "workflow_steps", "complexity_assessment", "decision_matrix", "failure_handling" "output_format", and more as needed. If you skip this step for non-easy tasks, workflows will likely be incomplete, or fail during execution for complex tasks. Calling it guarantees reliable, accurate, and end-to-end workflows aligned with the available tools and connections.
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Enable trigger
Enable a specific trigger for the authenticated user.
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Execute agent
Execute complex workflows using ai agent reasoning between multiple tool calls. use this for: complex multi-step workflows requiring reasoning, error handling and retry logic. use composio multi execute tool instead for: simple parallel operations, batch operations on similar data (e.g., fetch 5 emails, get 10 sent messages, retrieve multiple user profiles), independent tool calls that don't need each other's results, or bulk operations where all parameters are known upfront. performance: agent calls add ~2-3 seconds overhead. use for workflows >3 tools or requiring conditional logic. avoid for simple parameter passing.
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Execute Composio Tool
Execute a tool using the composio api.
Reaction Added Trigger
DEPRECATED: use `SLACK_MESSAGE_REACTION_ADDED` instead. Triggered when a reaction is added to a message in Slack.
Get Tool Dependency Graph
Get the dependency graph for a given tool, showing related parent tools that might be useful. this action calls the composio labs dependency graph api to retrieve tools that are commonly used together with or before the specified tool. this helps discover related tools and understand common workflows.
