What it does
Firecrawl Security Basics is an agent skill from jeremylongshore/tons-of-skills-marketplace. Secure Firecrawl identities, targets, request options, webhooks, untrusted content, retention, logs, and self-hosted exposure. Use when threat-modeling or hardening an integration. Trigger with "secure Firecrawl", "Firecrawl security review", or "Firecrawl secrets".
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 Security, covering Web scraping and Webhooks. 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.

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:
ReadGlobGrepWriteEdit
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 Security Basics 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 73 tokens; SKILL.md has 493 words of instructions outside code blocks.
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 Security Baseline
Overview
Protect both directions of the integration: credentials and requests sent to Firecrawl, and hostile or sensitive content returned from target sites.
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
Cloud uses Bearer API keys; enterprise controls can restrict key endpoints/formats and source IPs and can add threat protection and SIEM evidence. Webhooks use X-Firecrawl-Signature with sha256=hex over the raw body. Cache, ZDR, lockdown, headers/actions, profiles, screenshots, and self-hosting have distinct data and threat boundaries.
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
- Inventory secrets, teams/roles, key owners, environments, source networks, allowed endpoints/formats, domains, custom headers, retained data, webhooks, stores, and downstream actions.
- Move every key and webhook secret to an approved secret manager; use workload identity, least privilege, rotation, revocation, and separate environments.
- Canonicalize and authorize targets before requests. Block private/link-local networks, embedded credentials, disallowed redirects/ports, lookalike hosts, and unauthorized authenticated pages.
- Minimize formats, actions, headers, profiles, proxies, and retention. Apply key/IP/threat controls where available and keep application policy fail closed.
- Verify every webhook against raw bytes, require the sha256 prefix, decode equal-length hex, compare timing-safely, deduplicate webhookId, and acknowledge only accepted work.
- Treat scraped content and extracted JSON as untrusted. Sanitize active content, isolate it from privileged prompts/actions, validate schemas, and scan stored artifacts.
- For self-hosting, add supported authentication, network controls, TLS, durable stores, patching, backups, monitoring, and provider data-flow review before exposure.

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 security/data approval before authenticated scraping, custom headers, browser profiles/actions, sensitive retention, restriction changes, self-host exposure, or adding external providers.
Output
Return a threat model, identity and secret inventory, target and request controls, webhook verification design, content trust boundary, retention decision, self-host posture, tests, and residual risks.
Error Handling
- A secret appears in logs or artifacts: revoke/rotate as required and invoke incident handling.
- Webhook raw bytes are unavailable or signature malformed: reject the delivery.
- Target resolution or redirect escapes policy: stop before sending headers or credentials.
Examples
- "Verify Firecrawl webhooks" validates the exact signed raw body and sha256 format.
- "Pass customer cookies to any URL" is rejected until target, secret, retention, and session controls are approved.
Resources
Read official Firecrawl evidence before relying on an endpoint, SDK method, plan limit, price, retention option, or self-hosted release.
