AWETrim: Instructions file for Codex

AGENTS.md

AWETrim AGENTS.md is an instructions file for Codex, OpenCode from awegroup/AWETrim. It costs 2,181 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for AWETrim, a Python library for designing and optimising soft-kite airborne wind-energy systems. They explain the codebase, physics models, and links between scientific symbols and code names.

In plain words
What is it for?
Use them when changing AWETrim’s system, aerodynamics, structural, kinematics, or simulation code, especially when matching equations or physics references to implementation names.
Why use it?
They give coding agents the project context needed to work safely in a specialised scientific codebase. This reduces confusion about modules, unfinished areas, and domain terminology.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is awegroup/AWETrim's own configuration. It tells Codex and OpenCode how to work on AWETrim 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 AWETrim 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

AWETrim 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 8d 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.

AWETrim — Agent Context

What this repo is

AWETrim is a Python library for the design and optimisation of soft-kite Airborne Wind Energy Systems (AWES). It models the kite as a point mass in a course-aligned spherical reference frame, provides CasADi-based trajectory optimisation, and implements the winch/tether physics for pumping-cycle simulation.

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.
