coinmarketcal-automation
by ComposioHQcoinmarketcal-automation helps agents automate CoinMarketCal workflows through Composio Rube MCP, with setup checks, active connection guidance, and tool discovery before execution.
This skill scores 66/100, which makes it acceptable but limited for directory listing. It gives agents enough trigger and setup guidance to use Coinmarketcal through Rube MCP with less guesswork than a generic prompt, but directory users should expect a thin wrapper around dynamic tool discovery rather than a detailed, Coinmarketcal-specific workflow package.
- Valid skill frontmatter clearly declares the MCP dependency on `rube` and describes the purpose: automating Coinmarketcal tasks through Composio/Rube MCP.
- Prerequisites and setup steps tell users to connect Rube MCP, manage the Coinmarketcal connection, and confirm ACTIVE status before workflows.
- The skill gives an agent an important operational pattern: always call `RUBE_SEARCH_TOOLS` first to obtain current tool slugs, schemas, execution plans, and pitfalls.
- No support files, scripts, references, or README are included beyond SKILL.md, so adoption depends entirely on the short instruction file and live Rube tool discovery.
- The excerpted workflow guidance is mostly generic Rube MCP discovery/execution rather than concrete Coinmarketcal-specific automations or examples.
Overview of coinmarketcal-automation skill
What coinmarketcal-automation does
coinmarketcal-automation is a Claude skill for automating CoinMarketCal-related workflows through Composio’s Rube MCP server. It is designed to help an agent discover the current CoinMarketCal tool schema, verify an active connection, and then execute calendar-style crypto event operations with less guesswork than a generic prompt.
The important detail is that the skill does not hard-code a fixed API shape. Its core instruction is to call RUBE_SEARCH_TOOLS first, because available CoinMarketCal actions and input schemas can change.
Best-fit users and jobs
This skill is a good fit if you want an AI agent to work with CoinMarketCal data as part of a broader crypto research, alerting, content, or workflow automation process. Typical uses include checking available CoinMarketCal operations, retrieving event-related information, preparing research inputs, or connecting CoinMarketCal tasks into an MCP-based agent workflow.
It is especially useful for teams already using Composio, Rube MCP, or Claude skills and wanting coinmarketcal-automation for Workflow Automation rather than a one-off manual lookup.
What makes this skill different
The main value of the coinmarketcal-automation skill is operational discipline: it tells the agent to verify Rube availability, manage the CoinMarketCal connection, discover tools, inspect schemas, and only then execute. That reduces failures caused by stale assumptions about tool names, required fields, or authentication state.
The repository is intentionally lightweight: the install decision mostly depends on whether you use Rube MCP and need CoinMarketCal automation, not on extra scripts or local code.
How to Use coinmarketcal-automation skill
coinmarketcal-automation install context
Install the skill from the Composio skills repository in the same environment where your Claude-compatible skill runner is configured:
npx skills add ComposioHQ/awesome-claude-skills --skill coinmarketcal-automation
You also need Rube MCP available in your client configuration. The source skill points to https://rube.app/mcp as the MCP server endpoint. After adding it, confirm that RUBE_SEARCH_TOOLS is callable. Then use RUBE_MANAGE_CONNECTIONS with toolkit coinmarketcal and complete the returned authorization flow if the connection is not ACTIVE.
Do not treat installation alone as enough. The skill depends on a live MCP connection and an active CoinMarketCal toolkit connection.
Inputs the agent needs
For reliable coinmarketcal-automation usage, give the agent a specific CoinMarketCal task, the desired output format, and any constraints. Weak input is: “Check CoinMarketCal.” Stronger input is:
“Use coinmarketcal-automation to find the available CoinMarketCal tools, confirm the connection is active, then retrieve upcoming crypto calendar events relevant to Ethereum ecosystem projects. Return a concise table with event name, project, date, source fields available, and any uncertainty. Do not invent missing fields.”
This works better because it tells the agent to discover tools first, limits the scope, defines the output, and warns against filling gaps.
Recommended workflow
A practical coinmarketcal-automation guide should follow this sequence:
- Open
composio-skills/coinmarketcal-automation/SKILL.md. - Confirm the prerequisites: Rube MCP,
RUBE_SEARCH_TOOLS, and activecoinmarketcalconnection. - Ask the agent to call
RUBE_SEARCH_TOOLSfor your exact use case, not a vague generic query. - Review the returned tool slugs, schemas, execution plan, and pitfalls.
- Execute only after the required fields are known.
- Ask for a summary that separates returned data from assumptions.
The most important repository file is SKILL.md; there are no visible helper scripts, references, or README files in this skill folder, so the behavior is driven by the skill instructions and live Rube tool discovery.
Prompt pattern for better results
Use prompts that make schema discovery explicit:
“Before taking action, call RUBE_SEARCH_TOOLS with use case: ‘CoinMarketCal event lookup for upcoming exchange listings and project milestones.’ Use the returned schema exactly. If the CoinMarketCal connection is inactive, call RUBE_MANAGE_CONNECTIONS and tell me what authorization step is required. Once active, run the appropriate tool and return only fields supplied by the tool.”
This reduces two common failures: assuming an outdated tool name and treating unavailable fields as facts.
coinmarketcal-automation skill FAQ
Is coinmarketcal-automation useful without Rube MCP?
No. The skill’s execution path depends on Rube MCP tools, especially RUBE_SEARCH_TOOLS and RUBE_MANAGE_CONNECTIONS. If your agent environment cannot add MCP servers or call Rube tools, this skill will not provide much value beyond documenting a workflow pattern.
How is it better than an ordinary prompt?
An ordinary prompt may ask the model to “use CoinMarketCal,” but it may not know the current Composio tool slug, input schema, required authentication state, or recommended execution plan. coinmarketcal-automation makes tool discovery the first step, which is the key difference for dependable automation.
Is this skill beginner-friendly?
It is beginner-friendly if you are already comfortable adding an MCP server and following an auth link. It is not ideal as a first skill for users unfamiliar with MCP, tool calls, or connection management. Beginners should first verify that their client exposes Rube tools before trying CoinMarketCal workflows.
When should I not use this skill?
Do not use it for trading advice, unsupported data guarantees, or workflows that require local scripts included with the repository. The skill is also not a replacement for reviewing CoinMarketCal’s own data terms, API limits, or the Composio toolkit documentation at composio.dev/toolkits/coinmarketcal.
How to Improve coinmarketcal-automation skill
Improve coinmarketcal-automation inputs
Better inputs produce better tool searches. Include the event type, asset universe, time window, and output format. For example, “upcoming mainnet launches for top-200 market cap assets in the next 30 days” is more actionable than “crypto events.”
If you care about downstream workflow automation, also specify whether the result should be formatted for a report, spreadsheet, alert, CRM note, or another agent step.
Watch for common failure modes
The most common failure is skipping RUBE_SEARCH_TOOLS and assuming a tool schema. Another is continuing after RUBE_MANAGE_CONNECTIONS shows the CoinMarketCal connection is not active. A third is asking for fields the tool does not return, which can lead to inferred or hallucinated values.
Require the agent to state which tool it selected and which fields came from the schema before presenting final results.
Iterate after the first output
After the first run, refine by narrowing scope, adding filters, or changing the output structure. A useful follow-up is:
“Using the same discovered CoinMarketCal schema, rerun with a 14-day window and include only events with enough returned metadata to verify project, event type, and date.”
This improves precision without changing the workflow.
Add local guidance if your team repeats tasks
Because the repository folder appears to contain only SKILL.md, teams with recurring needs may want to add their own runbook outside the upstream skill: approved event categories, preferred date windows, validation rules, and standard report templates. That turns coinmarketcal-automation from a general connector skill into a repeatable internal workflow.
