simple-modern-uv: Instructions file for Codex

AGENTS.md

simple-modern-uv AGENTS.md is an instructions file for Codex, OpenCode from jlevy/simple-modern-uv. It costs 765 tokens per session, scanned A, original, MIT.

A project instruction file for AI agents working on a Copier template repository, which generates projects from a reusable template.

In plain words
What is it for?
Use it to guide agents through tbd issue tracking, Markdown checks, non-interactive template rendering, and smoke testing the generated project.
Why use it?
It records the repository’s required task-tracking, formatting, rendering, and testing procedures so agents can work consistently.

Instructions file for CodexOpenCode

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

This is jlevy/simple-modern-uv's own configuration. It tells Codex and OpenCode how to work on simple-modern-uv 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 simple-modern-uv 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

simple-modern-uv 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 1mo 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.

Project Instructions for AI Agents

This file provides instructions and context for AI coding agents working on this project.

tbd

This repository uses tbd for git-native issue tracking (beads), spec-driven planning, and on-demand engineering guidelines. As the agent, you operate tbd on the user’s behalf — translate their requests into tbd actions rather than telling them to run commands.

  • Run tbd prime to load current project state and the full tbd workflow.
  • Run tbd skill for the complete reusable tbd skill instructions.
  • Run tbd shortcut --list and tbd guidelines --list for on-demand resources.
  • Track all work as beads: tbd create, tbd ready, tbd close, and tbd sync.

Build and Test

This is a Copier template repo, not a Python project itself; there is no pyproject.toml to sync at the root. Validation means rendering the template and exercising the render:

# Auto-format all Markdown docs (including *.md.jinja); check-only variant for CI:
make format
make format-check

# Render the template non-interactively (smoke test):
SMOKE_DIR=$(mktemp -d)
uvx --exclude-newer "14 days" [email protected] copy --defaults --vcs-ref=HEAD \
  --data package_name=smoke-test \
  --data package_github_org=testorg . "$SMOKE_DIR"

# Dynamic versioning needs an initial commit before installation:
cd "$SMOKE_DIR"
git init --initial-branch=main
git add .
git -c user.name=Smoke -c [email protected] \
  commit -m "Initial commit"
make install
make lint-check
make test

Architecture Overview

  • template/: the Copier template source that ships to generated projects (*.jinja files are rendered; everything else copies as-is). The template/Makefile and template/devtools/lint.py are what downstream projects use, not this repo.
  • copier.yml: template questions and validation; the single source of truth for template variables.
  • skills/simple-modern-uv/: the portable agent workflow bundle. Its SKILL.md is the concise router; the one-level references/ files own the new, selective, migration, and update procedures. Keep README discovery and generated agent guidance aligned with these routes.
  • updating.md: the full maintenance and release flow (downstream jlevy/simple-modern-uv-template repo is the release gate).
  • docs/project/: maintainer research, frozen release evidence, and implementation records.

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.
