What is project-structure?

Guidance for organizing a modeling project into directories and standard project files. It covers where libraries, designs, knowledge, data, and working files belong.

Use it to decide where files go and to work with project overviews, architecture documents, requirements, and directory conventions.

It reduces confusion about file locations and helps keep project structure consistent as the work grows.

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	$0.00110	$0.01844
Opus 5.5	$0.00044	$0.00738
Sonnet 5.5	$0.00022	$0.00369
Haiku 4.5	$0.00011	$0.00184

Security

Grade A, and why

project-structure 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 24d 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 — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Before executing this skill, read .agentic-mbse/claude.md in Claude Code or .agentic-mbse/codex.md in Codex. Resolve supporting paths from this skill’s installed directory; keep generated outputs in the project or a temporary directory. Read referenced skills from .agents/skills/<name>/SKILL.md when their guidance is needed.

Project Structure

The 4-directory information architecture, model file organization, and key project files.

Core Principle

Every file has exactly one home determined by its information role. The 4-directory model answers four questions: "What do we know?" (knowledge/), "What are we building?" (modeling_project/), "What's in progress?" (work/), and "What are the models?" (models/).

When to Reference

/onboard — setting up project structure for new projects
/design-model — placing definitions in library vs designs
/implement-model — creating files in correct locations
/plan-model — planning file creation phases (library before designs)
/spec-model — understanding existing model landscape
/backlog — understanding work item structure

The 4-Directory Model

`work/`	"What's in progress?"	BACKLOG.md, active/completed work items, learnings

project-structure is a skill published in the GitHub repository 1cFE/fusion-tea (5 stars, last pushed 24d ago), licensed MIT. It adds 110 tokens to every session and 1,844 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-09-29.
