Signex: Skill for Claude Code

.claude/skills/db-save-items/SKILL.md

db-save-items is a skill for Claude Code from zhiyuzi/Signex. It costs 36 tokens per session (353 once invoked), scanned A, original, AGPL-3.0.

A skill that saves collected data items in an SQLite database, which is a small file-based database. It removes duplicates using each item's source and source ID.

In plain words
What is it for?
Use it after a Sensor has collected data items and they need to be stored in SQLite.
Why use it?
It preserves collected data in a searchable store and prevents the same source item from being saved repeatedly.

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

db-save-items 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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/save.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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.
