What is drawio-architect?

A command that creates an OCI architecture diagram in Draw.io from Terraform configuration or a written description. OCI is Oracle Cloud Infrastructure, and Terraform is a tool for describing cloud resources as code.

Use it to produce a styled .drawio diagram of an Oracle Cloud architecture, using project settings or detected Terraform and OCI configuration.

It turns cloud configuration into a visual map, making services, regions, compartments, and connections easier to inspect and explain.

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	$0.00061	$0.07555
Opus 5.5	$0.00024	$0.03022
Sonnet 5.5	$0.00012	$0.01511
Haiku 4.5	$0.00006	$0.00756

Security

Grade B, and why

drawio-architect scanned grade B with 1 finding 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts

The opening of the file, as written. The whole thing — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/drawio-architect

Produce <Subject>_Architecture.drawio (+ .png) that matches the plugin's reference look. The layout is computed by scripts/oci_layout.py from a model dict; your job is to fill the model correctly and pass the gate. Conventions, schema and the custom-layout API are in ${CLAUDE_PLUGIN_ROOT}/skills/oci-drawio-architect/SKILL.md.

Global rules:

NEVER copy drawio_builder.py (or any script) into the project. Generated scripts import from the plugin: sys.path.insert(0, "<abs>/scripts"). Resolve the absolute path first with echo "$CLAUDE_PLUGIN_ROOT" and paste it literally (the user runs the script outside Claude Code).
Use the recipe (oci_layout.write_diagram) unless the architecture cannot be expressed by it (see Step 3.4).
Never report success while Step 5's gate fails. Iterate at most 3 times, then report the remaining problems verbatim.
Input is $ARGUMENTS; if empty, ask (Step 1).

Step 0 - Settings

If .claude/oci-drawio-architect.local.md exists, read its YAML frontmatter and use the keys below.
Else run python3 "${CLAUDE_PLUGIN_ROOT}/scripts/detect_settings.py" [terraform_dir] (add --no-cli when the OCI CLI is absent, unconfigured or hangs; each CLI call is bounded to 8 s). Exit 1 = nothing detected; exit 2 = the directory does not exist. Stdout is the frontmatter; stderr is the summary.
Required values: region (settings) and subject (Step 1). Ask with AskUserQuestion ONLY for values that are still missing. Do not ask about logos, tenancy or compartment; use them when present, omit them otherwise.
Write the settings file from this template, keeping only detected/answered keys (values are JSON-quoted scalars; lists as JSON):

---
tenancy_name: "mytenancy"
tenancy_ocid: "ocid1.tenancy.oc1..aaaa"
region: "eu-frankfurt-1"
region_label: "Frankfurt"
oci_profile: "DEFAULT"
compartment: "prod"
vcns: [{"name": "app-vcn", "cidr": "10.0.0.0/16"}]
purpose: "network"
logo_light: "logos/company_logo_dark.png"
terraform_dir: "terraform/environments/prod"
