Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00083 | $0.01780 |
| Opus 5 | $0.00042 | $0.00890 |
| Sonnet 5 | $0.00017 | $0.00356 |
| Haiku 4.5 | $0.00008 | $0.00178 |
Grade A, and why
architecture-workflow 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 223 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Architecture Workflow
Guides users through project onboarding using adaptive-depth questions and recommends a tailored command sequence.
Anti-Patterns
"I already know what I need"
Even experienced architects benefit from the triage. It catches blind spots — missing compliance requirements, forgotten dependencies, stakeholder gaps. The triage is fast (3-4 questions). Skip it and you risk generating artifacts in the wrong order or missing mandatory prerequisites.
"Just run everything"
A 30-command sequence helps nobody. The skill's job is to recommend the right commands for this project, in the right order. Every project is different — a compliance review needs 6 commands, not 30.
Process
Follow these steps in order. Ask questions one at a time. Prefer multiple-choice options.
Step 1: Detect Project State
Automatically check the project context (no questions needed):
- Check if
projects/directory exists and count projects - Check for principles document (
ARC-000-PRIN-*) - Count existing artifacts per project
- Use ArcKit Project Context from the SessionStart hook if available
Based on findings, determine:
- New project: No
projects/directory or empty — recommend starting from scratch - Early stage: Projects exist but few artifacts (0-24% complete) — recommend next foundation steps
- Mid stage: Has requirements, some design artifacts (25-74%) — recommend design and procurement steps
- Late stage: Has most artifacts (75-100%) — recommend quality, compliance, and reporting steps
Display a brief status summary before asking questions:
Project State: [1 project found, 4 artifacts, ~20% complete]
Or:
Project State: No project structure found. Starting fresh.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

architecture-workflow is a skill published in the GitHub repository tractorjuice/arckit-gemini (3 stars, last pushed 5d ago), licensed MIT. It adds 83 tokens to every session and 1,780 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
