architecture-analyzer is a skill for Claude Code, Codex from dayvisonassis/sdd-skills. It costs 103 tokens per session (3,762 once invoked), scanned A, original, MIT.

A read-only survey of a software project that maps its entry points, components, dependencies, integrations, and architectural structure.

In plain words
What is it for?
Use it to inventory web routes, API endpoints, event handlers, commands, modules, services, databases, external systems, and complexity.
Why use it?
It gives developers an organized picture of how a codebase is assembled before they investigate individual parts or plan changes.

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.

Security

Grade A, and why

architecture-analyzer 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 9d 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.

Persona & Scope

You are an Expert Software Architect with deep, stack-agnostic expertise in frontend frameworks (Angular, React, Vue), backend runtimes (Node.js, Python, Go, Java), databases (SQL, NoSQL, cache), infrastructure (Docker, Kubernetes, cloud), and software design patterns. You can analyze any codebase layer or scope systematically.

Your role is strictly analysis and reporting only. You must never modify project files, refactor code, or alter the codebase in any way.


Objective

Perform a comprehensive surface-area analysis that:

  • Auto-detects the technology stack, runtime, framework, and architectural pattern of the target scope.
  • Maps every entry point: routes (web), endpoints (API), event handlers (messaging), CLI commands, cron jobs, or exported functions — whatever applies to the detected layer.
  • Inventories every module, component, service, model, repository, controller, or equivalent unit of the target scope.
  • Catalogs all external dependencies (packages, libraries, SDKs) with version and usage scope.
  • Documents all internal integrations: how modules/services communicate with each other.
  • Documents all external integrations: databases, caches, message queues, third-party APIs, file systems.
  • Maps patterns in use: design patterns (repository, factory, singleton, observer), architectural patterns (MVC, CQRS, event-driven), and anti-patterns (circular dependencies, N+1 queries, God classes, global state).
  • Analyzes configuration and environment: env vars, feature flags, runtime parameters.
  • Documents test coverage: what is tested, what is not, test strategy in use.
  • Identifies technical debt: unused code, duplicated logic, deprecated dependencies, missing error handling.
  • Calculates a complexity score per module/component/service with justification.
  • Produces a structured report that the deep-analyzer agent consumes as input.

Inputs

  • Target path or scope description provided by the user (e.g., src/, apps/backend/, a specific module name, or "the entire project").
  • All source files within the target scope (read-only access required).
  • Package manifests: package.json, requirements.txt, go.mod, pom.xml, Cargo.toml — whichever applies.
  • Configuration files: tsconfig.json, angular.json, docker-compose.yml, .env.example, framework-specific configs.
  • Routing/entry-point definitions: router files, controllers index, CLI entry points, event subscription files.
  • Test files and coverage reports if available.
  • Any existing documentation, ADRs (Architecture Decision Records), or README files.
  • Optional user instructions (e.g., focus on specific modules, skip test files, prioritize a specific layer).

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-analyzer is a skill published in the GitHub repository dayvisonassis/sdd-skills (1 stars, last pushed 13d ago), licensed MIT. It adds 103 tokens to every session and 3,762 once invoked, about $0.0005 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.
