linkr-control

linkr-control is a skill for Claude Code, Codex from rcarmo/piclaw-addons. It costs 36 tokens per session (1,032 once invoked), scanned A, original, MIT.

A procedure for controlling a selected computer through a Radxa Linkr KVM, which provides remote screen viewing and keyboard or mouse input. It requires observing the screen, previewing changes, executing approved actions, and checking the result.

In plain words
What is it for?
Use it to operate an explicitly selected remote computer when safer access such as SSH or browser automation is unavailable.
Why use it?
A successful network request does not prove that the remote computer accepted the action. Fresh screenshots, target checks, and verification reduce the risk of acting on the wrong machine or screen.

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

linkr-control 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 1mo 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.

The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Linkr control

Use this skill when Piclaw must interact with a specific machine through a Radxa Linkr KVM and safer direct methods such as SSH, guest agents, or browser automation are unavailable.

See tool contract and safety rules.

Start read-only

Before any input:

  1. Resolve the target with profile.list, profile.select, and status.
  2. Inspect capabilities and note any unsupported families.
  3. Capture a fresh snapshot and read both the image and metadata.
  4. Confirm the visible screen matches the authorised task and targetIdentity.

Do not infer authority from a selected profile alone.

Core operating loop

  1. Observe — take snapshot and identify OS, active prompt, focus, and ambiguity.
  2. Plan — choose the smallest next action that could safely advance the task.
  3. Preview — call the mutating action without execute:true first when the next step is nontrivial.
  4. Execute — resend with execute:true only when the effect is authorised.
  5. Verify — take a new snapshot and confirm the result before continuing.

HTTP or API success only acknowledges delivery. It does not prove the remote application accepted the action.

Actions to prefer

For ordinary interactive control, prefer these actions and fields:

  • snapshot
  • key.tap with device_id, key
  • key.combo with device_id, keys
  • key.repeat with device_id, key, count, interval_ms
  • text with device_id, text
  • mouse.move with device_id, x, y
  • mouse.click with device_id, x, y
  • mouse.drag with device_id, x, y, to_x, to_y
  • mouse.scroll with device_id, wheel_y, wheel_x
  • input.batch with device_id, events
  • input.release

Use job.start only for bounded local capture or firmware-entry jobs, not as a generic macro recorder.

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.

linkr-control is a skill published in the GitHub repository rcarmo/piclaw-addons (23 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 1,032 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-13.
