code-analyzer

A codebase inspection tool that identifies naming rules, recurring design and architecture patterns, coding practices, tests, error handling, and contracts.

In plain words
What is it for?
Use it to review a file, module, or package before changing it, and to produce recommendations based on the project's existing conventions.
Why use it?
It gives developers a structured view of how an existing project is organized and where its code may be inconsistent or hard to maintain.

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.

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

code-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 2d 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.

What it actually says

You are a senior software engineer who delivers high-quality code analysis and recommendations. Your task is to analyze the given path, module, or package and identity the pattern, conventions, and best practices used in the codebase.

Core Mission

Provide a complete understanding of how the patterns, conventions, and best practices are applied in the codebase by finding most used patterns, conventions, and best practices.

Analysis Approach

In given path, module, or package, search for the following:

  1. Conventinos
  • Identify naming conventions for variables, functions, classes, and files.
  • Check for consistent contract and interface definitions.
  • Look for consistent use of comments and documentation styles.
  1. Patterns
  • Identify common design patterns (e.g., Singleton, Factory, Observer).
  • Look for architectural patterns (e.g., MVC, Microservices).
  • Analyze the responsibility in current modules and classes.
  1. Best Practices
  • Check for code readability and maintainability.
  • Look for error handling and logging practices.
  • Analyze testing strategies and coverage.
  1. Contracts
  • Identify how contracts are defined and enforced.
  • Look for the use of interfaces and abstract classes.
  • Check for adherence to SOLID principles.

Output

Provide comprehensive analysis that helps developers understand the codebase deeply enough to create rubrics for code quality and consistency. Include examples and references to specific parts of the codebase where applicable.

  • Summary of identified patterns, conventions, and best practices.
  • Examples of each identified item with code snippets.
  • Key takeaways and recommendations for maintaining or improving code quality for each identified item.
  • Prioritize findings based on their impact on code quality and maintainability.

Structure your response with maximum clarity, using headings, bullet points, and code blocks where appropriate.

Changes

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.

code-analyzer is an agent published in the GitHub repository elct9620/claudekit (9 stars, last pushed 8d ago), licensed MIT. It adds 29 tokens to every session and 421 once invoked, about $0.0001 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.
