pentest-recon-osint

pentest-recon-osint is a skill for Codex from 0x-Professor/Agent-Skills-Hub. It costs 22 tokens per session (325 once invoked), scanned A, original, Apache-2.0.

A passive reconnaissance and open-source intelligence tool for collecting information about an authorised target without directly contacting its systems. Open-source intelligence means information gathered from publicly available sources.

In plain words
What is it for?
Use it to find subdomains, email identities, technology details, leaked credentials, and other passive indicators within an approved scope.
Why use it?
It helps security testers map a target’s visible attack surface without starting active tests. It also gathers the results in consistent files for later security work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pentest-recon-osint scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/recon_osint.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Pentest Recon OSINT

Stage

  • PTES: 2
  • MITRE: TA0043 - Reconnaissance

Objective

Collect subdomains, identities, leak indicators, and passive attack surface telemetry.

Required Workflow

  1. Validate scope before any active action and reject out-of-scope targets.
  2. Run only authorized checks aligned to PTES, OWASP WSTG, NIST SP 800-115, and MITRE ATT&CK.
  3. Write findings in canonical finding_schema format with reproducible PoC notes.
  4. Honor dry-run mode and require explicit --i-have-authorization for live execution.
  5. Export deterministic artifacts for downstream skill consumption.

Execution

python skills/pentest-recon-osint/scripts/recon_osint.py --scope scope.json --target <target> --input <path> --output <path> --format json --dry-run

Outputs

  • subdomains.txt
  • emails.txt
  • technologies.json
  • leaked-creds.json
  • osint-report.json

References

  • references/tools.md
  • skills/autonomous-pentester/shared/scope_schema.json
  • skills/autonomous-pentester/shared/finding_schema.json
WARNING AUTHORIZED USE ONLY
This skill executes real security testing tools against live targets.
Use only with written authorization.

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
