Turn a marked build error into focused research
When an error needs more than a quick guess, mark it and bring back documentation relevant to the library involved.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Query-docs
Retrieves and queries up-to-date documentation and code examples from Context7 for any programming library or framework. You must call 'resolve-library-id' first to obtain the exact Context7-compatible library ID required to use this tool, UNLESS the user explicitly provides a library ID in the format '/org/project' or '/org/project/version' in their query. IMPORTANT: Do not call this tool more than 3 times per question. If you cannot find what you need after 3 calls, use the best information you have.
Why this helps
Build errors interrupt planned work, and tracking down which docs apply can make the interruption last longer.
- Make a visible signal when an error needs documentation research.
- Look up docs for the implicated package or framework.
- Return examples that can help the team assess a fix.
Setup
Build it in a few focused steps.
- 1Connect Slack and Context7 MCP to Notis once through the portal.
- 2Create an automation with a plain-language prompt to query Context7 for docs relevant to a reacted-to library or framework build error.
- 3Select Message Reaction Added and choose a channel for run reports.
- 4Test by reacting to a real build-error message with the chosen reaction.
Questions about this workflow
Can Context7 diagnose any build error?
It can retrieve relevant library documentation and examples, but it may not explain errors unrelated to documented APIs.
Should the error include a package name?
Including the package or framework and version helps resolve the correct documentation source.

Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Query-docs
Retrieves and queries up-to-date documentation and code examples from Context7 for any programming library or framework. You must call 'resolve-library-id' first to obtain the exact Context7-compatible library ID required to use this tool, UNLESS the user explicitly provides a library ID in the format '/org/project' or '/org/project/version' in their query. IMPORTANT: Do not call this tool more than 3 times per question. If you cannot find what you need after 3 calls, use the best information you have.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Resolve-library-id
Resolves a package/product name to a Context7-compatible library ID and returns matching libraries. You MUST call this function before 'query-docs' to obtain a valid Context7-compatible library ID UNLESS the user explicitly provides a library ID in the format '/org/project' or '/org/project/version' in their query. Selection Process: 1. Analyze the query to understand what library/package the user is looking for 2. Return the most relevant match based on: - Name similarity to the query (exact matches prioritized) - Description relevance to the query's intent - Documentation coverage (prioritize libraries with higher Code Snippet counts) - Source reputation (consider libraries with High or Medium reputation more authoritative) - Benchmark Score: Quality indicator (100 is the highest score) Response Format: - Return the selected library ID in a clearly marked section - Provide a brief explanation for why this library was chosen - If multiple good matches exist, acknowledge this but proceed with the most relevant one - If no good matches exist, clearly state this and suggest query refinements For ambiguous queries, request clarification before proceeding with a best-guess match. IMPORTANT: Do not call this tool more than 3 times per question. If you cannot find what you need after 3 calls, use the best result you have.
