Linkr qualify device

Use this skill before trusting a new Linkr profile for BIOS work, installation, or recovery.

Qualification is how you learn what is real for one machine without pretending the result is portable to every machine.

Required profile baseline

The profile should be configured in Settings with at least:

• id
• label
• origin
• tokenKeychain
• targetIdentity
• inputEnabled

If targetIdentity is vague or clearly stale, update the operational record before relying on the profile.

Read-only first

Start with:

• profile.list
• profile.select
• status
• capabilities
• snapshot

Confirm the visible attached machine matches the intended profile. Qualification belongs to the machine actually on the cable, not just the Linkr appliance.

What to qualify

Qualify, with evidence:

• screenshot freshness and resolution;
• practical cadence for repeated snapshots;
• keyboard layout assumptions;
• simple reversible HID effects;
• whether a documented firmware-entry key seems valid for this machine;
• whether unsupported families remain unsupported in practice.

Reversible HID checks

Only with operator consent:

• preview a tiny action first;
• resend with execute:true;
• verify with a new snapshot.

Good examples are moving focus one step in a visible menu or opening a harmless boot prompt. Do not begin with destructive actions.

Firmware timing qualification

Qualify firmware-entry timing only during a maintenance window. Use:

• reboot.plan
• firmware.entry.plan
• job.start with a job payload like:

{
  "action": "job.start",
  "device_id": "lab-workstation-a",
  "job": {
    "kind": "firmware-entry",
    "duration_ms": 15000,
    "capture_interval_ms": 1000,
    "key": "F2",
    "key_evidence": "Vendor splash prompt and operator both say F2.",
    "tap_start_ms": 500,
    "tap_interval_ms": 250,
    "tap_duration_ms": 4000
  },
  "execute": true
}

Tie the resulting notes to the exact targetIdentity, visible firmware version when known, and date. A recipe learned on one firmware revision or one cable path may not survive hardware changes.
