firecrawl — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited firecrawl (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

firecrawl search "query" --scrape --limit 3Follow this escalation pattern:
map --search to find the right URL, then scrape it.| Need | Command | When |
|---|---|---|
| Find pages on a topic | search | No specific URL yet |
| Get a page's content | scrape | Have a URL, page is static or JS-rendered |
| Find URLs within a site | map | Need to locate a specific subpage |
| Bulk extract a site section | crawl | Need many pages (e.g., all /docs/) |
| AI-powered data extraction | agent | Need structured data from complex sites |
| Interact with a page | browser | Content requires clicks, form fills, pagination, or login |
| Download a site to files | download | Save an entire site as local files |
For detailed command reference, use the individual skill for each command (e.g., firecrawl-search, firecrawl-browser) or run firecrawl <command> --help.
Scrape vs browser:
scrape first. It handles static pages and JS-rendered SPAs.browser when you need to interact with a page, such as clicking buttons, filling out forms, navigating through a complex site, infinite scroll, or when scrape fails to grab all the content you need.search instead.Avoid redundant fetches:
search --scrape already fetches full page content. Don't re-scrape those URLs..firecrawl/ for existing data before fetching again.Firecrawl is the default for public, text-based web content. Route elsewhere when the source is auth-walled, audio/video, or when you already have the text and just need it shorter:
| Situation | Use instead | Why | |
|---|---|---|---|
X / Twitter post, thread, article, or /bookmarks | mktg-x skill | Twitter serves a degraded logged-out page to unauthenticated clients. mktg-x uses stored MKTG_X_AUTH_TOKEN to fetch the real content. Firecrawl will return a stub. | |
| YouTube / podcast / TikTok / any audio or video URL | mktg transcribe <url> | Firecrawl returns the page chrome (title, description), not the spoken content. mktg transcribe runs the yt-dlp → ffmpeg → whisper.cpp pipeline and returns the full transcript. | |
| Fetched page is too long to ideate on | Chain into summarize after the firecrawl call | Firecrawl is the fetcher, summarize is the compressor. `firecrawl scrape <url> -o page.md && cat page.md \ | summarize --tldr` is the canonical pattern — don't re-fetch or ask firecrawl to summarize. |
Escalation rule of thumb: if a human would need to log in, press play, or skim-and-condense to get value from the source, firecrawl alone is the wrong tool.
Unless the user specifies to return in context, write results to .firecrawl/ with -o. Add .firecrawl/ to .gitignore. Always quote URLs - shell interprets ? and & as special characters.
firecrawl search "react hooks" -o .firecrawl/search-react-hooks.json --json
firecrawl scrape "<url>" -o .firecrawl/page.mdNaming conventions:
.firecrawl/search-{query}.json
.firecrawl/search-{query}-scraped.json
.firecrawl/{site}-{path}.mdNever read entire output files at once. Use grep, head, or incremental reads:
wc -l .firecrawl/file.md && head -50 .firecrawl/file.md
grep -n "keyword" .firecrawl/file.mdSingle format outputs raw content. Multiple formats (e.g., --format markdown,links) output JSON.
These patterns are useful when working with file-based output (-o flag) for complex tasks:
# Extract URLs from search
jq -r '.data.web[].url' .firecrawl/search.json
# Get titles and URLs
jq -r '.data.web[] | "\(.title): \(.url)"' .firecrawl/search.jsonRun independent operations in parallel. Check firecrawl --status for concurrency limit:
firecrawl scrape "<url-1>" -o .firecrawl/1.md &
firecrawl scrape "<url-2>" -o .firecrawl/2.md &
firecrawl scrape "<url-3>" -o .firecrawl/3.md &
waitFor browser, launch separate sessions for independent tasks and operate them in parallel via --session <id>.
