qr

A macOS command that creates a high-resolution PNG image of a QR code from supplied text. A QR code is a pattern that phones can scan to open or store information.

In plain words
What is it for?
Use it to make QR images for links, text, or other data, then locate the generated file.
Why use it?
It creates the code locally without installing extra software or relying on a website.

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.

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

qr 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 2d 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.

What it actually says

Generate a QR code PNG via CoreImage. Deterministic.

Use Bash to execute (one call, then stop):

/Users/esaruoho/work/apple/bin/sal-qr $ARGUMENTS && open -R "$(echo $ARGUMENTS | awk '{print $NF}')"

After the command completes, report only the output path.

Changes

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.

qr is a command published in the GitHub repository esaruoho/apple (11 stars, last pushed 5d ago), licensed MIT. It adds 29 tokens to every session and 123 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
