What it does

Common Architecture Audit is an agent skill from HoangNguyen0403/agent-skills-standard. Audit structural debt, logic leakage, and monolithic components across Web, Mobile, and Backend codebases. Use when reviewing architecture, assessing tech debt, detecting logic in wrong layers, or identifying God classes.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `evals/evals.json`, `references/PATTERNS.md` and `references/detection.md`).

It sits in Development, covering Technical debt. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Reviewing architecture
  • Assessing tech debt
  • Detecting logic in wrong layers
  • Identifying God classes

Example prompts

  • “/common-architecture-audit”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Discover Structural Duplication
  2. Detect Logic Leakage (by Ecosystem)
  3. Identify Monoliths
  4. Audit Resource Performance

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Common Architecture Audit loads about 643 tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 62 tokens; SKILL.md has 221 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~643
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Architecture Audit

Priority: P1 (HIGH)

1. Discover Structural Duplication

Identify split sources of truth by searching for redundant directory patterns.

  • Compare Service.ts vs ServiceNew.ts vs ServiceV2.ts.
  • Check for /v1, /v2 or "Refactor" folders.

See implementation examples for detection scripts.

2. Detect Logic Leakage (by Ecosystem)

Find business logic trapped in wrong layer.

  • Web (React/Next.js/Vue): grep -rE "useEffect|useState|useMemo" components --include="*.tsx" | wc -l — if components/ hook count > 20x hooks/ folder, architecture monolithic.
  • Mobile (Flutter/React Native): grep -rE "http\.|dio\.|socket\." lib/widgets --include="*.dart" | wc -l — I/O or state mutation > 5 lines in build() High Debt.
  • Backend (NestJS/Go/Spring): grep -rE "Repository\.|Query\.|db\." src/controllers --include="*.ts" | wc -l — Controllers must only handle request parsing and response formatting.

3. Identify Monoliths

Flag massive files violating Single Responsibility Principle.

  • UI: > 500 lines (Medium), > 1,000 lines (Critical).
  • Backend Services: > 1,500 lines indicates "God Class".

See implementation examples for monolith detection scripts.

4. Audit Resource Performance

Check for large metadata or constants impacting IDE performance and binary size.

  • Resources > 1,000 lines require granulation.

See implementation examples for resource audit scripts.

Scoring Impact

  • Layer Violation: -15 per business logic instance in UI/Controller layer.
  • Structural Fragmentation: -10 per duplicated legacy entity.
  • Monoliths: -10 per unit > 1,000 lines.

Anti-Patterns

  • No applying generic patterns over project-specific rules: Respect existing architecture constraints.
  • No ignoring error handling or edge cases: Audit must cover boundary conditions.
