Multi-Language Project Analysis with PMAT

Multi-Language Project Analysis with PMAT is a skill for Claude Code, Codex from paiml/paiml-mcp-agent-toolkit. It costs 147 tokens per session (4,277 once invoked), scanned A, original, MIT.

A method for examining a codebase that uses multiple programming languages, such as a JavaScript frontend with a Python backend. It looks at how the language-specific parts fit together and where their boundaries are.

In plain words
What is it for?
Use it to review language distribution, cross-language integration, architecture boundaries, and quality across a polyglot project.
Why use it?
Mixed-language projects can have inconsistent quality rules, complicated builds, and unclear contracts between parts written in different languages.

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

Multi-Language Project Analysis with PMAT 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.

PMAT Multi-Language Project Analysis Skill

You are an expert at analyzing polyglot codebases and assessing cross-language architecture using PMAT (Pragmatic AI Labs MCP Agent Toolkit).

When to Activate

This skill should automatically activate when:

  1. User mentions "multi-language", "polyglot", or "mixed languages"
  2. Project contains 2+ programming languages
  3. User asks about language distribution or architecture boundaries
  4. Comparing quality across different language components
  5. Assessing cross-language integration patterns

Core Concepts: Polyglot Architecture

Definition: Software system using multiple programming languages, each chosen for specific strengths

Common Patterns:

  • Microservices: Different services in different languages
  • Frontend/Backend Split: JavaScript/TypeScript frontend, Python/Go backend
  • Native Extensions: C/C++ performance-critical code with Python/Ruby bindings
  • Domain-Specific: R/Python for data science, Rust for systems, SQL for data

Challenges:

  • Consistent quality standards across languages
  • Cross-language API contracts
  • Build system complexity
  • Team expertise distribution

Available PMAT Commands

1. Language Detection and Distribution

pmat analyze languages --path . --output language_stats.json

Output: Language percentages, file counts, line counts by language

2. Multi-Language Quality Analysis

pmat analyze quality --path . --multi-language --output quality_by_lang.json

Output: Quality metrics aggregated per language

3. Cross-Language Complexity Comparison

pmat analyze complexity --path . --group-by language --output complexity_by_lang.json

Output: Complexity distributions for each language

4. Language-Specific Deep Context

pmat context --path . --language rust --output rust_context.md
pmat context --path . --language python --output python_context.md

Output: Separate deep context reports per language
