augint-opencodex 0.7.1

Render local Codex and OpenCode repo config from .ai-codex.json

augint-opencodex

augint-opencodex is a Python tool that renders local Codex and OpenCode project configuration from a single tracked manifest, .ai-codex.json.

The first working slice is implemented here. It ships a real ai-codex CLI with:

• ai-codex sync to read .ai-codex.json and render .ai-opencodex.md, .codex/config.toml, opencode.json, and shared skills
• ai-codex doctor to inspect manifest resolution, generated files, local ignore setup, and staged generated artifacts
• a first-pass profile model with augint and gov
• local-only ignore handling through .git/info/exclude

Installation

For local dev:

uv sync --group dev

Once the package is published, the intended install flows are:

uvx --from augint-opencodex ai-codex sync
uv tool install augint-opencodex
ai-codex sync

Manifest

This tool expects a tracked .ai-codex.json file in the target repository. If it is missing when you run ai-codex sync, the command will prompt for a profile and create a minimal manifest before rendering. Pass --profile augint or --profile gov to skip the prompt (useful for scripts). --check still fails when the manifest is missing so CI does not silently initialize repos.

The current schema lives in schemas/ai-codex.schema.json.

OpenCode and Codex manifest fields

The opencode and codex sections let the manifest fully express non-secret tool configuration instead of deferring those details to a separate launcher:

• opencode.local_provider — OpenAI-compatible local endpoint (e.g. Ollama) rendered as provider.<name>.options.baseURL in opencode.json.
• opencode.default_model — top-level model in opencode.json.
• opencode.models — curated catalog attached to the local provider.
• opencode.bedrock.enabled / opencode.bedrock.models — toggles the amazon-bedrock provider entry with the listed model IDs.
• codex.provider — openai or aws. Emitted as a comment in .codex/config.toml so the runtime launcher knows which auth path to select. Raw secrets are never written to generated files.
• codex.model, codex.approval_policy, codex.sandbox_mode, codex.web_search — override the defaults carried by the active profile.

Commands

Render files into the current repository:

uv run ai-codex sync

Preview pending changes without writing:

uv run ai-codex sync --dry-run

Fail if the repo is out of sync:

uv run ai-codex sync --check

Inspect the current repo state:

uv run ai-codex doctor

Generated Files

The first slice writes:

• .ai-opencodex.md
• .codex/config.toml
• opencode.json
• .agents/skills/README.md
• .agents/skills/org-python-tooling/SKILL.md when patterns.org_python_library is enabled

Generated outputs are added to .git/info/exclude by default so target repositories do not need to commit them.

Canonical Ownership

There is one source of truth for each generated file, and one tool responsible for each runtime concern. This split keeps .ai-shell.yaml from drifting out of sync with generated config.

File ownership

File	Owner	Notes
.ai-codex.json	user (tracked)	Source of truth for all generated files
opencode.json	augint-opencodex	Repo root; generated
.codex/config.toml	augint-opencodex	Repo root; generated
.ai-opencodex.md	augint-opencodex	Repo root; generated
.agents/skills/**	augint-opencodex	Generated

Generated files MUST NOT be hand-edited. Re-run ai-codex sync after manifest changes.

Runtime ownership (augint-shell)

augint-shell is responsible only for runtime and container behavior:

• bind-mounting .codex/ and opencode.json into the container
• injecting secrets (OPENAI_API_KEY, AWS credentials) at launch time
• selecting Bedrock vs OpenAI auth paths based on the manifest's codex.provider / opencode.bedrock.enabled signals
• CLI launch flags (ai-shell opencode, ai-shell codex)

augint-shell should not ship template copies of opencode.json or .codex/config.toml, and .ai-shell.yaml should stop documenting [opencode] / [codex] config shape that duplicates .ai-codex.json.

Consumption inside ai-shell containers

The generated files live at repo root in the host working directory. Inside an ai-shell container, they are consumed as follows:

• opencode.json — the ai-shell opencode command launches OpenCode with the repo's working directory as CWD, so OpenCode discovers opencode.json directly. ai-shell opencode --provider local|aws selects which provider block from the generated opencode.json is active at launch and injects the matching credentials or endpoint env vars. It does not rewrite the file.
• .codex/config.toml — ai-shell bind-mounts the host .codex/ directory into the container. Codex is launched with CODEX_HOME=$(pwd)/.codex so the generated file serves as the Codex home config. ai-shell codex --provider openai|aws mirrors codex.provider from the manifest and sets the corresponding auth env vars (OPENAI_API_KEY, AWS credential chain). Secrets are never written into .codex/config.toml or opencode.json.
• .ai-opencodex.md — Codex discovers it through the project_doc_fallback_filenames entry in the generated .codex/config.toml; OpenCode reads it through the instructions block in opencode.json.

If a repo uses augint-opencodex but is launched outside ai-shell, the same files are still consumed by running codex / opencode directly from the repo root with CODEX_HOME=$(pwd)/.codex.

augint-shell migration

Once a repo adopts augint-opencodex, the following can be removed from augint-shell:

• src/ai_shell/templates/opencode/opencode.json
• src/ai_shell/templates/codex/config.toml
• [opencode] and [codex] config blocks in the scaffolded .ai-shell.yaml template (beyond runtime toggles like provider)
• codex_openai_api_key handling in config.py moves to pure runtime env injection

Runtime-only fields that remain in .ai-shell.yaml:

• opencode.provider (local|aws) — chooses which provider block from opencode.json the launcher should activate
• Secret material passed via environment variables

Dogfooding This Repo

This repository is set up to dogfood the generated instructions flow without a root AGENTS.md.

1. Keep .ai-codex.json tracked in the repo root.
2. Run uv run ai-codex sync to generate .ai-opencodex.md, .codex/config.toml, and the other local-only artifacts.
3. Start Codex with CODEX_HOME=$(pwd)/.codex codex so Codex uses the generated .codex/config.toml as its home config and discovers .ai-opencodex.md via project_doc_fallback_filenames.

Avoid creating a root AGENTS.md here. Codex checks AGENTS.md before fallback filenames in the same directory, so a root AGENTS.md would shadow .ai-opencodex.md and split Codex from the generated OpenCode instructions.

Organizational Python Standard

This project uses ai-lls-lib/ in the planning repo as the concrete reference for the organization-wide Python package and tooling standard:

• uv-first packaging and development workflow
• src/ layout and console scripts from [project.scripts]
• ruff, mypy, pytest, and pre-commit
• security and compliance checks in CI
• Conventional Commit and semantic-release-compatible versioning
• a stable Makefile task surface
