What is articraft-authoring?

An authoring workflow for creating, editing, checking, and finalizing Articraft articulated-object records in a local library. It supports managed generation, no-key Codex generation, and explicitly requested external authoring.

Use it when producing or repairing an Articraft asset or record, choosing the appropriate generation mode and validating the result through Articraft's tools.

It keeps records, metadata, traces, and run details consistent with Articraft's required process instead of assembling them manually.

About the project

Articraft is a toolset for generating, viewing, and working with articulated 3D assets from text prompts. Researchers and developers use its generation code, viewer, SDK, command-line tools, and dataset; the repository points current development to a successor project.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00028	$0.00914
Opus 5.5	$0.00011	$0.00366
Sonnet 5.5	$0.00006	$0.00183

Security

Grade A, and why

articraft-authoring 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.

Articraft Authoring

Use this skill when the user asks Codex to create, edit, fix, improve, check, or finalize an Articraft asset or record.

Core Rule

There are three supported Articraft authoring modes. Choose the mode from the user's request before creating a record.

Use native Articraft generation when the user needs Articraft-managed run metadata, cost accounting, turn counts, or the full agent trajectory. This path requires the relevant provider API key.
Use no-key Codex generation when the user wants Codex access without provider API keys. This path uses --provider codex-cli inside Articraft's internal harness, so Articraft still owns the loop, tools, compile feedback, turn counts, compile-attempt counts, record persistence, and trajectory.
Use external Codex authoring only when the user explicitly asks Codex to manually edit model.py outside the internal harness. This path creates an external-agent record and intentionally has no Articraft internal trace.

Never manually create record directories, invent record metadata, copy record folders, write traces, or bypass the CLI.

Read the repository contract before external authoring:

sed -n '1,220p' EXTERNAL_AGENT_DATA.md

Also read the core quality requirements before writing geometry:

agent/prompts/sections/designer_common.md
agent/prompts/sections/link_naming.md

Use SDK docs and examples while authoring:

sdk/_docs/
sdk/_examples/

Setup

From the Articraft repo root:

uv sync --group dev
uv run articraft init

If the user wants a specific data folder, pass --data-dir or set ARTICRAFT_DATA_DIR.

Create A New Record

For a full Articraft run with cost, turn count, and trajectory, use native generation:

uv run articraft generate "<prompt>"

For no-key Codex generation with Articraft loop parity, use the Codex CLI provider:

uv run articraft generate --provider codex-cli --model <codex-model-id> "<prompt>"

For image-conditioned no-key Codex generation:
