What it does
Performing Osint With Spiderfoot is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. Automate OSINT collection with the SpiderFoot REST API and CLI (sf.py/spiderfoot-cli) across 200+ modules, selecting scan modes (footprint, investigate, passive) and parsing results for domains, IPs, emails, leaked credentials, and DNS records into a target intelligence profile. Use when mapping an organization's attack surface or profiling a target for threat intelligence.
Its SKILL.md is about 610 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `SKILL.es.md`, `references/api-reference.md` and `scripts/agent.py`).
It sits in Security, covering OSINT. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.
When your agent uses it
- Mapping an organizations attack surface
- Profiling a target for threat intelligence
Example prompts
- “/performing-osint-with-spiderfoot”
Requirements
- Python 3
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Connect to SpiderFoot REST API or use CLI interface
- Create a new scan with target specification (domain, IP, email, name)
- Select scan modules by use case (all, footprint, investigate, passive)
- Monitor scan progress via API polling
- Retrieve and parse scan results by data element type
- Extract key findings: subdomains, IPs, emails, leaked credentials
- Generate structured OSINT intelligence report
What it can do on your machine
Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
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 no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Performing Osint With Spiderfoot loads about 608 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 102 tokens; SKILL.md has 227 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); the scripts in this folder are not scanned.

Performing OSINT with SpiderFoot
Overview
SpiderFoot is an open-source OSINT automation tool with 200+ modules that integrates with data sources for threat intelligence and attack surface mapping. This skill uses the SpiderFoot REST API and CLI (sf.py/spiderfoot-cli) to create and manage scans, select modules by use case (footprint, investigate, passive), parse structured results for domains, IPs, email addresses, leaked credentials, and DNS records, and generate target intelligence profiles.
When to Use
- When conducting security assessments that involve performing osint with spiderfoot
- When following incident response procedures for related security events
- When performing scheduled security testing or auditing activities
- When validating security controls through hands-on testing
Prerequisites
- SpiderFoot 4.0+ installed or SpiderFoot HX cloud account
- Python 3.8+ with requests library
- SpiderFoot server running on default port 5001
- Optional: API keys for VirusTotal, Shodan, HaveIBeenPwned modules
Steps
- Connect to SpiderFoot REST API or use CLI interface
- Create a new scan with target specification (domain, IP, email, name)
- Select scan modules by use case (all, footprint, investigate, passive)
- Monitor scan progress via API polling
- Retrieve and parse scan results by data element type
- Extract key findings: subdomains, IPs, emails, leaked credentials
- Generate structured OSINT intelligence report
Expected Output
JSON report containing OSINT findings organized by data type (domains, IPs, emails, credentials, DNS records), module source attribution, and target profile summary with risk indicators.
