matlab-design-digital-filter

matlab-design-digital-filter is a skill for Claude Code from matlab/matlab-agentic-toolkit. It costs 54 tokens per session (1,541 once invoked), scanned A, original, no licence file.

A MATLAB guide for designing digital filters that keep wanted parts of a sampled signal and reduce unwanted noise or interference.

In plain words
What is it for?
Use it to build low-pass, high-pass, band-pass, band-stop, or notch filters and compare their results.
Why use it?
It helps choose and validate FIR or IIR filters for different frequency ranges instead of relying on trial and error.

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

matlab-design-digital-filter 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.

matlab-design-digital-filter is a skill published in the GitHub repository matlab/matlab-agentic-toolkit (1,207 stars, last pushed 4d ago), with no licence file. It adds 54 tokens to every session and 1,541 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 2026-09-03.
