matryca-plumber: Skill for Claude Code

.agents/skills/matryca-logseq-io/SKILL.md

matryca-logseq-io is a skill for Claude Code, Codex from MarcoPorcellato/matryca-plumber. It costs 45 tokens per session (107 once invoked), scanned A, original, Apache-2.0.

Guidance for choosing between reading and writing Logseq files directly or using Logseq's local HTTP API, a way for software to communicate with the running app.

In plain words
What is it for?
Use it when implementing graph reads or writes, background indexing, live Logseq connections, authentication, or communication with Logseq through JSON-RPC.
Why use it?
It helps avoid unsafe or incompatible access when changing notes, background indexes, live integrations, authentication, or JSON-RPC messages.

This is MarcoPorcellato/matryca-plumber's own configuration. It tells Claude Code and Codex how to work on matryca-plumber itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything matryca-plumber configures →

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

matryca-logseq-io 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 9d 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 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.
