OpenSDL: Instructions file for Codex

AGENTS.md

OpenSDL AGENTS.md is an instructions file for Codex, OpenCode from fl-sean03/OpenSDL. It costs 916 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for OpenSDL, a modular framework for computational and autonomous laboratories. They describe the project layout, its commands, and its architecture rules.

In plain words
What is it for?
Use them to install dependencies, run the test and quality checks, build documentation, generate schemas, validate the viewer, or run the simulated laboratory example.
Why use it?
They give developers and coding agents a shared reference for how the repository is organized and how changes are checked. This reduces guesswork about testing, linting, documentation, schemas, and examples.

Instructions file for CodexOpenCode

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

This is fl-sean03/OpenSDL's own configuration. It tells Codex and OpenCode how to work on OpenSDL 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 OpenSDL 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

OpenSDL 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 2mo 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.

Repository instructions

Project

OpenSDL is a modular framework for computational and autonomous laboratories.

Layout

  • reusable packages: packages/
  • deployable applications: apps/
  • integrations: adapters/
  • scientific extensions: domain-packs/
  • complete examples: examples/
  • cross-package tests: tests/

Commands

  • install: uv sync --locked --all-packages --group dev
  • test: make test — workspace suite and the digital-twin surrogate overlay
  • lint: make lint — lockfile, Ruff lint and format, Pyright, boundaries, schema drift, repository, and versions
  • viewer: make viewer — surrogate viewer lint, typecheck, tests, build, and committed asset drift
  • docs: make docs — mkdocs build --strict
  • example: make example — the complete simulated campaign
  • format: make format — applies Ruff formatting and safe fixes; make lint enforces it
  • schemas: uv run --locked python scripts/generate-schemas.py

make test, make lint, make viewer, make docs, make example, and make showcase together cover every check the pull-request CI job enforces. make showcase re-derives the campaign the README frame is rendered from, which takes about a minute and is why CI runs it as its own job. make scene covers the one that runs separately: the headless Blender rebuild proving the committed scene is reproducible from source. It needs the exact Blender version recorded in the scene's node inventory and takes several minutes. A bare uv run --locked pytest is not the full suite: testpaths excludes examples/, so the surrogate tests are reachable only through make test or make surrogate, and the showcase campaign only through make showcase. Narrower targets (unit, integration, e2e, conformance, typecheck, boundaries, validate, showcase, surrogate, propagation, scene) and the raw command behind each target are in the Makefile.

Architecture rules

  • core imports no internal package.
  • Applications compose packages; business logic stays in packages.
  • Vendor or facility behavior belongs in adapters.
  • Every operational adapter needs simulation and conformance coverage.
  • Public models are typed and exported as versioned schemas.
  • Database access goes through repository interfaces.
  • A change is complete when code, tests, schemas, examples, and documentation agree.
  • A laboratory with one instrument stays expressible in about fifteen manifest lines, runnable in one process against SQLite, with no scheduler, broker, or optional service. Facility features are opt-in by configuration, never by requirement, and a change that lengthens the minimum manifest needs justifying. tests/test_minimal_laboratory.py enforces this.

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.
