What it takes

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

Input	With otlite	`linkook` receives
Username`u:`	`otlite run linkook -- u:johndoe`	`linkook johndoe`

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/linkook/johndoe/<time>_linkook_johndoe_<run id>.txt
results/linkook/johndoe/<time>_linkook_johndoe_<run id>.meta.json
results/linkook/johndoe/<time>_linkook_johndoe_<run id>.envelope.json

{
  "envelope": 1,
  "tool": "linkook@1.1.3",
  "runtime": "otlite",
  "input": { "target": "johndoe" },
  "case": null,
  "started_at": "…", "ended_at": "…", "duration_ms": …,
  "exit_code": 0,
  "status": "complete",
  "entities": [{ "type": "url", "value": "…" }, …],
  "warnings": [],
  "output": { "path": "results/linkook/johndoe/<time>_linkook_johndoe_<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 linkook

otlite extract linkook

otlite diff linkook johndoe

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

otlite auto johndoe
