firecrawl-knowledge-base is a Claude Code skill that crawls web content with Firecrawl and organizes it into clean markdown for RAG, docs mirrors, or fine-tuning datasets.

About

firecrawl-knowledge-base is a skill that crawls and scrapes web content with Firecrawl and organizes it into clean, LLM-ready markdown. It supports reference libraries, RAG-ready chunks, documentation mirrors, topic corpora, and fine-tuning datasets. A developer uses it to bootstrap a vector store or mirror third-party docs offline without writing a bespoke crawler. It requires a FIRECRAWL_API_KEY and runs an onboarding step to infer source, depth, and output goal.

  • Turns URLs or topics into LLM-ready markdown
  • Output modes: reference, RAG, training, docs mirror
  • Uses Firecrawl map, search, and scrape
  • Requires FIRECRAWL_API_KEY
  • Preserves code examples and tables

How do I turn a website or topic into clean, structured markdown ready for RAG or fine-tuning without maintaining my own crawler?

Crawl and scrape web content with Firecrawl into clean LLM-ready markdown for RAG, docs mirrors, topic corpora, or fine-tuning datasets.

Who is it for?

Developers bootstrapping a vector store, mirroring third-party docs offline, or building training data from public web pages.

Skip if: Users who need a self-hosted or keyless crawler, since it depends on the hosted Firecrawl service and a FIRECRAWL_API_KEY.

When should I use this skill?

When building a knowledge base from web content for local reference docs, RAG chunks, fine-tuning datasets, documentation mirrors, or topic corpora.

What you get

A directory of organized LLM-ready markdown plus manifests (sources.json, manifest.json, or training-data.jsonl) depending on output mode.

  • LLM-ready markdown files
  • sources.json / manifest.json
  • training-data.jsonl for training mode

By the numbers

  • 4 output modes
  • asks at most 1-3 onboarding questions

Firecrawl Knowledge Base

Use this to turn URLs or topics into organized LLM-ready content.

Onboarding Interview

Infer the source, goal, depth, and output location from context. If the source and goal are clear, proceed immediately.

Ask at most 1-3 concise questions only if blocked, such as the source URL/topic, whether the output is reference/RAG/training/docs, or training format if training is requested.

Firecrawl Collection Plan

Use Firecrawl map for documentation sites, search for topic-based corpora, scrape pages into markdown, and preserve code examples and tables.

For files, follow the Firecrawl download-style convention:

.firecrawl/
  <hostname>/
    <path>/
      index.md

Parallel Work

If appropriate, use sub-agents or equivalent parallel task runners:

  • one docs section per researcher
  • official docs, tutorials, community discussions, and references by source type
  • source scraping vs chunk generation vs manifest generation

Output Modes

  • Reference: markdown files, index.md, and sources.json.
  • RAG: markdown files plus chunk files and manifest.json.
  • Training: scraped source files plus training-data.jsonl and training-metadata.json.
  • Docs mirror: complete markdown mirror with a table of contents.
