000_general

General development rules for tfmcp, a Rust command-line tool for managing Terraform through the Model Context Protocol.

In plain words
What is it for?
Use them when adding features, documenting public interfaces, writing tests, preparing semantic-versioned releases, or maintaining Terraform compatibility.
Why use it?
They provide shared expectations for code quality, releases, documentation, and tests across the project.

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

000_general 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 3d 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

General Project Guidelines

Project Overview

  • This is tfmcp (Terraform Model Context Protocol Tool), a CLI tool that helps you interact with Terraform via MCP.
  • The project is written in Rust and integrates with Terraform to enable AI-assisted infrastructure management.
  • Always maintain high code quality and adherence to best practices.

Development Workflow

  • Follow semantic versioning for releases.
  • Use the Release.sh script for versioning and releases.
  • Write meaningful commit messages following conventional commits format.

Documentation

  • Keep documentation up-to-date as features evolve.
  • Document public APIs, functions, and modules.
  • Include examples where appropriate.

Testing

  • Write unit tests for core functionality.
  • Ensure test coverage for critical paths.
  • Test against different Terraform versions when applicable.
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.
