design-review

design-review is a skill for Claude Code, Codex from dimetron/pi-go. It costs 30 tokens per session (2,968 once invoked), scanned A, original, MIT.

A read-only review of an entire Go codebase that scores naming, structure, consistency, interfaces, error handling, and other design qualities. It produces findings with file and line references.

In plain words
What is it for?
Use it to audit architecture and Go style across a project and receive scored, actionable recommendations without modifying the code.
Why use it?
It provides a structured assessment when you are unfamiliar with a codebase or preparing for a major refactor or release. It also distinguishes broad design review from checking only changed files.

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

design-review 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 10d 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.

Design Review

Perform a comprehensive design review of the Go codebase. Evaluate code quality, naming conventions, consistency, and architectural patterns. Produce a scored report with actionable improvements.

When to use

Use this skill when:

  • Auditing overall design quality before a major refactor or release
  • Onboarding to an unfamiliar Go codebase and need a structured assessment
  • Comparing codebase against Go idioms after a period of rapid development

Do NOT use for:

  • Reviewing a single PR or uncommitted diff (use code-review instead)
  • Writing new code or fixing bugs
  • Running linters/tests for CI gating (use code-review instead)

Relationship to code-review

Aspect design-review code-review
Scope Entire codebase or package Changed files only
Action Read-only audit, scored report Fix issues, enforce gates
Focus Architecture, patterns, idioms Correctness, coverage, linting
Output Scorecard + recommendations Pass/fail gates + fixes applied

Dimensions

Score each dimension 1-10 and provide specific file:line references for issues found.

1. Naming Conventions

  • Exported types/functions follow Go conventions (MixedCaps, no underscores)
  • Package names are short, lowercase, singular (not utils, helpers, common)
  • Interface names use -er suffix where appropriate (Reader, Writer)
  • Receiver names are short (1-2 chars), consistent within type
  • Variable names: short in small scopes, descriptive in large scopes
  • Acronyms are all-caps (ID, URL, HTTP, not Id, Url, Http)
  • Test function names follow TestFuncName_Scenario pattern
  • Constants use MixedCaps, not SCREAMING_SNAKE

2. Package Design

  • Packages have clear, singular responsibility
  • No circular dependencies
  • Internal packages used appropriately for implementation details
  • Package-level doc comments present
  • No God packages (too many responsibilities)
  • Reasonable file sizes (flag files > 500 lines)

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.
