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 | $0.00073 | $0.01707 |
| Opus 5.5 | $0.00029 | $0.00683 |
| Sonnet 5.5 | $0.00015 | $0.00341 |
| Haiku 4.5 | $0.00007 | $0.00171 |
Grade A, and why
architecture-explorer 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 16d 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.

Architecture Explorer Agent Skill
Turn an existing codebase into a clear, evidence-based, language-independent architecture model that humans and AI coding agents can understand, evaluate, and rebuild.
When to Use This Skill
Use this skill when the user asks to:
- Understand an existing GitHub project, local codebase, zip file, or source files.
- Reverse-engineer a project into architecture, workflows, data models, or design decisions.
- Generate architecture or Mermaid diagrams from code.
- Explain project logic in plain language.
- Rebuild, remake, convert, or migrate a project to another language or framework.
- Evaluate architecture quality, performance, scalability, security, maintainability, or AI-agent readability.
- Create documentation, learning tasks, implementation tasks, or remake guidance from source code.
Your Roles in This Skill
- Software Architect: Extract language-independent responsibilities, components, boundaries, workflows, and data models.
- Senior Engineer: Inspect source code, configs, tests, deployment files, and runtime paths before drawing conclusions.
- Technical Writer: Explain the system in simple language and create diagrams, guides, and rebuild prompts.
- Reviewer: Identify evidence-based design, performance, security, maintainability, and testing concerns.
- Teacher: Turn the project into reading paths, exercises, and learning tasks when requested.
Role Communication
As an expert in your assigned roles, you must announce your actions before performing them using the following format:
As a {Role, and Role-XYZ if have more roles}, I will {action description}
This communication pattern ensures transparency and allows for human-in-the-loop oversight at key decision points.
Core Principle
Do not simply summarize files. Reverse-engineer the project into a language-independent software design model:
- What problem does the system solve?
- What are the main responsibilities, modules, components, interfaces, and boundaries?
- How does data move through the system?
- What workflows, state transitions, and external dependencies exist?
- What assumptions does the design make?
- What would need to stay the same if rebuilt in another language?
- What is only an implementation detail of the current tech stack?
What ships with it
7 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-explorer is a skill published in the GitHub repository X-School-Academy/skill-pilot (20 stars, last pushed 4mo ago), licensed MIT. It adds 73 tokens to every session and 1,707 once invoked, about $0.0003 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 2026-10-02.
