Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.00667 |
| Opus 5.5 | $0.00015 | $0.00267 |
| Sonnet 5.5 | $0.00008 | $0.00133 |
| Haiku 4.5 | $0.00004 | $0.00067 |
Grade A, and why
linkr-os-install 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.
How it starts
The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Linkr OS install
Use this skill only for authorised installation or reinstallation of an operating system on a specifically identified target machine.
This skill is intentionally conservative. It should stop on ambiguity rather than guess.
Required installation brief
Before beginning, obtain and restate:
- target profile and
targetIdentity; - OS name, version, edition, and architecture;
- verified ISO or installer source and checksum status;
- intended boot path, such as physical USB; virtual media is not implemented in v0.1;
- target disk identity and capacity;
- keep/erase policy;
- backup or disposable-device evidence;
- encryption plan;
- network constraints;
- post-install access plan.
If the task lacks a clearly identified target disk, stop.
Media rules
media.mount and media.eject are public action names, but they are currently unsupported in this add-on. The operator must provide physical or separately managed install media.
Installer workflow
At each installer screen:
- Capture
snapshot. - Describe the visible state and any ambiguity.
- Choose one small next step.
- Preview the HID action.
- Re-run with
execute:true. - Verify with a new
snapshot.
Typical checkpoints include:
- language and locale;
- keyboard layout;
- install versus rescue mode;
- storage or partitioning mode;
- disk selection;
- encryption and recovery-key prompts;
- user creation;
- bootloader target;
- final write summary.
Final disk-write approval
A general request like “install Linux” is not enough authority to pick a disk or erase data.
Pause at the actual final summary that commits disk changes and restate:
- selected disk by visible label/model/size;
- visible partitions or deletions;
- encryption decision;
- any warning about data loss.
Proceed only after explicit approval at that screen.
Secure Boot, TPM, and storage mode
Do not disable Secure Boot, TPM, or change storage-controller mode merely to make an installer continue. If those settings become blockers, stop and ask for explicit scope expansion.
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.
- 1mo ago First seen · 101 lines · 38 tokens per session scan A 7f399a2e3709
linkr-os-install is a skill published in the GitHub repository rcarmo/piclaw-addons (23 stars, last pushed yesterday), licensed MIT. It adds 38 tokens to every session and 667 once invoked, about $0.0002 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.
