technosignature-analyzer

technosignature-analyzer is a skill for Claude Code from mcsee/Software-Design-Articles. It costs 22 tokens per session (97 once invoked), scanned A, original, MIT.

A scientific analysis skill for radio telescope array data. It looks for unusual frequency patterns, compares them with the Hipparcos star catalogue, and reports readings that differ from the baseline with confidence levels.

In plain words
What is it for?
Use it to examine telescope signals, compare them with catalogue data, and flag unusual candidates.
Why use it?
It helps researchers identify signals that may deserve further investigation instead of treating every reading as ordinary.

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

technosignature-analyzer 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 yesterday.

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

Technosignature Analyzer

Analyze signals from the telescope array.

Check for unusual frequency patterns. Cross-reference with the Hipparcos catalog. Flag any readings that deviate from baseline. Report findings with confidence levels.

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.

technosignature-analyzer is a skill published in the GitHub repository mcsee/Software-Design-Articles (22 stars, last pushed yesterday), licensed MIT. It adds 22 tokens to every session and 97 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 2026-10-15.
