osint

osint is a skill for Claude Code from transilienceai/communitytools. It costs 27 tokens per session (443 once invoked), scanned A, original, MIT.

A guide for open-source intelligence, meaning the collection of information from publicly available sources about a company’s code, developers, systems, and exposed secrets.

In plain words
What is it for?
Use it to map company repositories and developer accounts, inspect code and commit history, scan for secrets, identify endpoints and internal services, and review dependencies for known risks.
Why use it?
It helps uncover information that may be visible in public repositories or forgotten version history, including credentials, internal names, and infrastructure details.

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

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 7d ago.

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

OSINT

Passive and semi-passive intelligence gathering focused on code repositories, developer footprints, and exposed secrets across public platforms.

Phases

1. Organization Discovery

  • Enumerate GitHub/GitLab/Bitbucket orgs for target company name variants
  • Find employee personal accounts linked to the target org
  • Identify archived, forked, and deleted repositories

2. Repository Analysis

  • Map all repos: tech stack, languages, CI/CD, dependencies
  • Identify internal hostnames, IPs, endpoints, environment names
  • Check for .env, config files, secrets in current code

3. Secret & Credential Scanning

  • Scan current code with gitleaks / trufflehog
  • Scan full git history (secrets removed in commits are still accessible)
  • Search with targeted dorks (see reference/repository-recon.md)

4. Code Intelligence

  • Extract API endpoints, auth patterns, internal service names
  • Review Dockerfiles, CI configs, IaC for infra details
  • Check dependency files for version-specific CVE candidates

Output

data/reconnaissance/repositories.json   # Repo inventory + findings
reports/reconnaissance_report.md        # OSINT section appended
raw/osint/                              # Raw tool outputs

Tools

trufflehog, gitleaks, gitrob, GitHub/GitLab search, gh CLI, git log

Rules

  1. Passive discovery first (search APIs, public pages) before any cloning
  2. Scan git history — deleted secrets are still in commit objects
  3. Check employee personal accounts, not just org accounts
  4. Document every discovered credential/secret immediately as a finding
  5. All output saved to {OUTPUT_DIR}/ per CLAUDE.md directory structure

Reference

  • reference/repository-recon.md - Dorks, tool commands, secret patterns, workflow
Files

What ships with it

1 file 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.
