What it does

Firecrawl Known Pitfalls is an agent skill from jeremylongshore/tons-of-skills-marketplace. Audit a Firecrawl integration for legacy v1 calls, unbounded crawls, incomplete pagination, unsafe retries, retention mistakes, and untrusted-content handling. Use when reviewing code or onboarding maintainers. Trigger with "Firecrawl pitfalls", "review Firecrawl code", or "Firecrawl anti-patterns".

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Designed for Claude Code; Firecrawl Cloud work requires network access

It sits in Data & Analytics, covering Web scraping. It works with Firecrawl. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Onboarding maintainers
  • With Firecrawl pitfalls
  • Review Firecrawl code
  • Firecrawl anti-patterns

Example prompts

  • “Firecrawl pitfalls”
  • “review Firecrawl code”
  • “Firecrawl anti-patterns”
  • “/firecrawl-known-pitfalls”

Requirements

  • A credential in FIRECRAWL_API_KEY
  • Compatibility (from SKILL.md): Designed for Claude Code; Firecrawl Cloud work requires network access
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Write, Edit

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Locate Firecrawl dependencies, imports, wrapper clients, REST paths, config, queues, webhooks, stores, tests, and deployment files.
  2. Flag legacy v0/v1 routes or FirecrawlApp-style methods unless they are intentionally isolated behind the documented feature-frozen…
  3. Find every crawl, batch, search, agent, and browser call. Require explicit scope, credit/time limits, cancellation ownership, and…
  4. Verify SDK versus REST response handling, metadata.statusCode checks, complete pagination, terminal-state handling, and idempotent webhook…
  5. Compare retry logic with the official error catalog. Reject retries for auth, credits, restrictions, validation, and other non-retryable…
  6. Trace scraped or extracted content into logs, prompts, stores, and actions. Require sanitization, provenance, prompt-injection boundaries…
  7. Rank findings by exploitability and impact, propose minimal fixes and regression tests, and verify the corrected paths.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • Write
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • FIRECRAWL_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code; Firecrawl Cloud work requires network access

    From compatibility in the SKILL.md frontmatter.

Context cost

Firecrawl Known Pitfalls loads about 1.1k tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 81 tokens; SKILL.md has 478 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~81
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Firecrawl Integration Pitfall Review

Overview

Find high-impact failure modes before production. Tie every finding to current Firecrawl behavior and repository evidence instead of applying a generic checklist.

Prerequisites

  • The target repository or integration path and the requested operator outcome.
  • The source authorization, data classification, and environment policy.
  • Current Firecrawl documentation, credentials only when needed, and an owner for approvals.

Current Contract

Common current hazards include legacy scrapeUrl/crawlUrl method names, implicit crawl scope, confusing API success with origin status, dropping pagination, retrying 4xx errors, assuming one credit per request, trusting scraped instructions, enabling cache on sensitive data, skipping webhook HMAC verification, and exposing the self-host quickstart.

Authentication

For authenticated Cloud operations, inject FIRECRAWL_API_KEY from an approved secret manager. REST requests use Authorization: Bearer with the key. Never print, commit, transmit, or place a key in a URL. Keyless access is suitable only where the current documentation explicitly allows it and the workload accepts its limits; production workflows should make identity and team ownership explicit.

Instructions

  1. Locate Firecrawl dependencies, imports, wrapper clients, REST paths, config, queues, webhooks, stores, tests, and deployment files.
  2. Flag legacy v0/v1 routes or FirecrawlApp-style methods unless they are intentionally isolated behind the documented feature-frozen compatibility surface.
  3. Find every crawl, batch, search, agent, and browser call. Require explicit scope, credit/time limits, cancellation ownership, and environment policy.
  4. Verify SDK versus REST response handling, metadata.statusCode checks, complete pagination, terminal-state handling, and idempotent webhook processing.
  5. Compare retry logic with the official error catalog. Reject retries for auth, credits, restrictions, validation, and other non-retryable failures.
  6. Trace scraped or extracted content into logs, prompts, stores, and actions. Require sanitization, provenance, prompt-injection boundaries, retention, and deletion.
  7. Rank findings by exploitability and impact, propose minimal fixes and regression tests, and verify the corrected paths.

Tool Discipline

Use Read, Glob, and Grep to inspect code, configuration, tests, and evidence. Use Write/Edit only for approved implementation or documentation changes. Do not call Firecrawl, rotate keys, change account settings, scrape a target, or deploy merely because this skill was invoked.

Approval Boundaries

Require approval before changing dependencies, expanding crawl scope, enabling raw formats/actions, weakening cache or retention safeguards, or auto-fixing production code.

Output

Return evidence-linked findings, severity, affected paths, current contract, recommended patch, tests, approvals, and residual risk. Report clean controls as evidence, not as a blanket assurance.

Error Handling

  • Current docs disagree with installed types: pin both versions and resolve the discrepancy before editing.
  • The target policy is missing: report the missing authority rather than assuming scraping is allowed.
  • A fix would change behavior broadly: isolate it behind a canary and rollback boundary.

Examples

  • "Review our Firecrawl wrapper" checks v2 methods, pagination, retries, provenance, and data boundaries.
  • "All requests return 200" still fails if captured documents have metadata.statusCode errors.

Resources

Read official Firecrawl evidence before relying on an endpoint, SDK method, plan limit, price, retention option, or self-hosted release.
