What it does

Firecrawl Migration Deep Dive is an agent skill from jeremylongshore/tons-of-skills-marketplace. Migrate a custom Puppeteer, Playwright, Cheerio, or third-party scraping workload to Firecrawl v2 with parity, policy, cost, and rollback evidence. Use when replacing an existing acquisition system. Trigger with "migrate to Firecrawl", "replace Playwright scraping", or "Firecrawl adoption".

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, Playwright and Puppeteer. 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.

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 Migration Deep Dive 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 80 tokens; SKILL.md has 477 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~80
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 Workload Migration

Overview

Replace a scraper only after defining observable equivalence. Preserve the old adapter until the new path meets content, policy, performance, and recovery gates.

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

Firecrawl can replace rendering, crawl discovery, mapping, search, parsing, and typed extraction, but one endpoint is not equivalent to every legacy workflow. Scrape, crawl, map, batch, parse, JSON extraction, actions, Browser, and Cloud/self-hosted capabilities have different contracts and costs.

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. Inventory legacy sources, login/session behavior, selectors/actions, discovery rules, formats, parsers, retries, proxies, schedules, storage, compliance controls, metrics, and operating cost.
  2. Create a source-to-Firecrawl capability map. Mark unsupported, Cloud-only, self-host-dependent, behavior-changing, and policy-sensitive requirements.
  3. Define an adapter contract and golden synthetic corpus with provenance, normalized content hashes, required-field coverage, latency, cost, and accepted variance.
  4. Implement the smallest v2 path behind a feature flag. Keep target authorization, explicit scope/limits, cache/retention, cancellation, and error typing visible.
  5. Shadow both paths on approved canaries, compare content and metadata without duplicating downstream writes, and investigate meaningful differences.
  6. Shift traffic in stages only after parity, security, spend, load, and rollback gates pass. Keep the old path available through the observation window.
  7. Remove legacy code and secrets only after rollback expiry, archive the decision and evidence, and verify dependency and data cleanup.

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 replaying authenticated sessions, changing target behavior or proxies, enabling Cloud-only processing, increasing spend, shifting traffic, or deleting the legacy path.

Output

Return the capability matrix, parity definition, adapter design, golden corpus, shadow results, cost and risk comparison, staged rollout, rollback evidence, and deferred gaps.

Error Handling

  • Required behavior has no Firecrawl equivalent: retain that legacy component or redesign explicitly.
  • Shadow outputs contain sensitive differences: quarantine the comparison and use content-free metrics.
  • Parity cannot be measured: block migration rather than accepting visual inspection alone.

Examples

  • "Replace our docs crawler" maps discovery, rendering, filters, retries, and indexing before shadowing.
  • "Delete Playwright first" is rejected until Firecrawl parity and rollback are proven.

Resources

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