Before you run it

Dual-use. otlite prints this before installing it: You are solely responsible for how you use these tools and for complying with all applicable laws. Use them only on targets you are authorized to investigate.

What it takes

Typed inputs after -- become H8Mail's own arguments. Anything else after -- passes through unchanged, so every option of the tool still works.

Input	With otlite	`h8mail` receives
Email`e:`	`otlite run h8mail -- e:ada@example.com`	`h8mail -t ada@example.com`

What a run leaves

Every run is saved under results/ where you run otlite (or --output, or OTLITE_RESULTS_DIR): what the tool printed, a sidecar with how it ran, and an envelope.

results/h8mail/ada@example.com/<time>_h8mail_ada@example.com_<run id>.txt
results/h8mail/ada@example.com/<time>_h8mail_ada@example.com_<run id>.meta.json
results/h8mail/ada@example.com/<time>_h8mail_ada@example.com_<run id>.envelope.json

{
  "envelope": 1,
  "tool": "h8mail@2.5.6",
  "runtime": "otlite",
  "input": { "target": "ada@example.com" },
  "case": null,
  "started_at": "…", "ended_at": "…", "duration_ms": …,
  "exit_code": 0,
  "status": "complete",
  "entities": [{ "type": "url", "value": "…" }, …],
  "warnings": [],
  "output": { "path": "results/h8mail/ada@example.com/<time>_h8mail_ada@example.com_<run id>.txt", "sha256": "…", "bytes": … }
}

The envelope's shape, the same for every tool; values elided. Its entities are the emails, domains, IP addresses and URLs found in the output, or the tool's own when it prints them.

otlite results --tool h8mail

otlite extract h8mail

otlite diff h8mail ada@example.com

List the saved runs, pull out every indicator, or compare the two latest runs against the same target.

With other tools

These run it with every other installed tool that takes the same input, a few at a time, and save each run:

otlite run --all e:ada@example.com

otlite auto ada@example.com
