arrowspace-skills AGENTS.md

arrowspace-skills AGENTS.md is an instructions file for Codex, OpenCode from Genefold/arrowspace-skills. It costs 419 tokens per session, scanned A, original, Apache-2.0.

A set of instructions and helper code for using ArrowSpace, a vector database that searches items by their meaning and analyses relationships between them.

In plain words
What is it for?
It helps build an ArrowSpace search index, query it, and inspect its spectral search behaviour using the included portable skills.
Why use it?
It gives a coding agent the library’s key facts, file layout and common commands, so it can work in the repository without rediscovering them.

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

arrowspace-skills AGENTS.md 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 3d 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

ArrowSpace Skills — Agent Context

This repository contains portable skill definitions for the ArrowSpace spectral vector search library.

Key facts

  • ArrowSpace is a vector database with spectral (graph Laplacian) awareness
  • Rust core: arrowspace-rs at github.com/Mec-iS/arrowspace-rs
  • Python bindings: pyarrowspace at github.com/tuned-org-uk/pyarrowspace, pip-installable as arrowspace
  • JOSS paper: doi:10.21105/joss.09002
  • Author: Lorenzo Moriondo (Mec-iS) — ArrowSpace creator, Genefold AI founder

Common operations

  1. pip install arrowspace to install the core library
  2. ArrowSpaceBuilder().build(params, items) to create an index
  3. aspace.search(query, gl, tau) to query
  4. Use arrowspace_skills utilities for parameter suggestion and tau tuning
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.
