diffbot-automation
by ComposioHQdiffbot-automation helps Claude use Diffbot through Composio Rube MCP by discovering current tool schemas, checking the Diffbot connection, and running structured web data tasks safely.
This skill scores 66/100, which means it is acceptable for directory listing but should be presented as a lightweight MCP workflow guide rather than a complete Diffbot automation package. It gives agents enough trigger and setup guidance to use Composio/Rube for Diffbot tasks with less guesswork than a generic prompt, but directory users should expect to rely on live tool discovery for actual schemas and task-specific execution details.
- Valid skill frontmatter clearly declares the `rube` MCP requirement and describes the Diffbot automation purpose.
- Prerequisites and setup steps tell agents to verify `RUBE_SEARCH_TOOLS`, manage the `diffbot` connection, and confirm ACTIVE status before execution.
- The repeated instruction to call `RUBE_SEARCH_TOOLS` first helps agents adapt to current Diffbot tool schemas instead of relying on stale parameters.
- No install command or support files are provided; setup depends on manually adding the Rube MCP endpoint and managing the Diffbot connection.
- Workflow guidance appears mostly generic to Rube tool discovery, with limited Diffbot-specific task examples or edge-case handling.
Overview of diffbot-automation skill
What diffbot-automation is for
diffbot-automation is a Claude skill for running Diffbot operations through Composio’s Rube MCP server. It is best for users who want an agent to discover current Diffbot tool schemas, verify the Diffbot connection, and execute structured web data tasks without hardcoding outdated API parameters. The main job-to-be-done is not “write a scraper from scratch,” but “use the available Diffbot toolkit safely through MCP.”
Best-fit users and workflows
This skill fits teams using Claude with MCP who already rely on Diffbot for page analysis, extraction, enrichment, or web data automation. It is especially useful when your workflow changes often, because the skill instructs the agent to call RUBE_SEARCH_TOOLS first instead of assuming static tool names or schemas. For diffbot-automation for Web Scraping, the strongest fit is structured extraction from web pages where Diffbot’s API is appropriate and the user can provide clear target URLs, desired fields, and output format.
Key differentiator: tool discovery first
The most important behavior in the diffbot-automation skill is mandatory tool discovery. Before attempting any Diffbot action, the agent should search Rube for the current Diffbot tools, inspect the returned schemas, then run the selected tool with valid inputs. This reduces failures caused by stale examples, renamed fields, or undocumented toolkit changes.
What to check before installing
The repository path contains a single SKILL.md and no extra scripts, references, rules, or metadata files. That makes the skill lightweight and easy to inspect, but it also means adoption depends on your MCP environment being configured correctly. Install it if you want a compact operating pattern for Diffbot via Rube; skip it if you need a full scraper framework, queue system, crawler, or custom Diffbot API wrapper.
How to Use diffbot-automation skill
diffbot-automation install context
A typical install command for this repository is:
npx skills add ComposioHQ/awesome-claude-skills --skill diffbot-automation
After installation, configure Rube MCP in your Claude-compatible client by adding https://rube.app/mcp as an MCP server. The upstream skill notes that no API keys are required for adding the endpoint, but you still need an active Diffbot connection managed through Rube. Verify that RUBE_SEARCH_TOOLS is available before expecting the skill to work.
Required setup before the first run
The practical setup sequence is:
- Confirm the MCP server exposes
RUBE_SEARCH_TOOLS. - Use
RUBE_MANAGE_CONNECTIONSwith toolkitdiffbot. - If the connection is not
ACTIVE, follow the returned authorization link. - Re-check connection status before running extraction or enrichment tasks.
- Ask the agent to discover the current tool schema for your exact use case.
Do not skip discovery. The skill’s central safety rule is: search tools first, then execute.
Turning a rough goal into a strong prompt
Weak prompt:
Scrape this website with Diffbot.
Stronger prompt:
Use the
diffbot-automationskill. First callRUBE_SEARCH_TOOLSfor a Diffbot task that extracts article metadata and main text from these URLs:[URL list]. Check the Diffbot connection withRUBE_MANAGE_CONNECTIONS. Then choose the best current Diffbot tool, follow its schema exactly, and return JSON withurl,title,author,date,text, and any extraction warnings.
This works better because it gives the agent the task type, source URLs, required fields, output shape, and permission to perform the discovery-and-connection workflow.
Files to read before serious usage
Start with composio-skills/diffbot-automation/SKILL.md. It contains the only authoritative workflow in this skill: prerequisites, MCP setup, tool discovery, connection checking, and execution pattern. Because there are no bundled helper scripts or examples, users should also review the live toolkit documentation at https://composio.dev/toolkits/diffbot when they need to understand Diffbot-specific capabilities beyond the skill’s brief workflow.
diffbot-automation skill FAQ
Is diffbot-automation a scraper?
Not exactly. diffbot-automation is an MCP skill that helps an agent use Diffbot tools through Composio Rube. Diffbot may perform web extraction, but this skill does not provide crawling infrastructure, proxy rotation, browser automation, scheduling, deduplication, or storage. Treat it as an agent operating procedure for Diffbot, not a complete web scraping platform.
Why not just ask Claude to use Diffbot?
A generic prompt may hallucinate tool names, use outdated parameters, or forget to check whether the connection is active. The diffbot-automation guide pattern forces a safer sequence: discover tools, verify connection, inspect schema, execute with valid inputs. That is the main reason to install it instead of relying on ordinary prompting.
Is this suitable for beginners?
It is beginner-friendly if you already use an MCP-enabled client and can follow an auth link for the Diffbot connection. It is not ideal for someone who has never configured MCP tools, because the skill assumes Rube MCP is available and that the agent can call RUBE_SEARCH_TOOLS and RUBE_MANAGE_CONNECTIONS.
When should I not use it?
Do not use this skill when you need local-only scraping, browser interaction, login automation outside Diffbot’s supported tools, or deterministic code you can run without an agent. Also avoid it when your organization cannot permit external MCP calls or Diffbot processing for the target data.
How to Improve diffbot-automation skill
Improve inputs for diffbot-automation results
Better inputs produce better tool selection. Provide target URLs or domains, task type, desired fields, output schema, volume, freshness requirements, and acceptable failure handling. For example: “Extract product names, prices, availability, and canonical URLs from these 50 product pages; return one JSON object per URL and flag pages where Diffbot confidence is low.”
Common failure modes to prevent
The most common failures are running before the Diffbot connection is active, skipping RUBE_SEARCH_TOOLS, using guessed schemas, and giving vague extraction goals. Another common issue is asking for broad crawling when the current available Diffbot tools may only support specific extraction or analysis actions. Ask the agent to show the discovered tool slug and required fields before execution if accuracy matters.
Iterate after the first output
After the first run, review missing fields, malformed records, duplicate URLs, low-confidence extraction, and unexpected page types. Then refine the prompt with stricter field definitions, examples of valid output, and rules for unavailable data. A useful second-pass instruction is: “Repeat using the same discovered schema, but normalize dates to ISO 8601, leave unknown fields as null, and include an errors array per URL.”
Repository improvements worth contributing
The skill would be stronger with sample prompts, example RUBE_SEARCH_TOOLS responses, task-specific recipes, and troubleshooting notes for inactive connections or schema mismatches. A small examples section for article extraction, organization enrichment, and product page extraction would make the diffbot-automation usage path clearer without turning the skill into a full framework.
