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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.05180 |
| Opus 5 | $0.00000 | $0.02590 |
| Sonnet 5 | $0.00000 | $0.01036 |
| Haiku 4.5 | $0.00000 | $0.00518 |
Grade A, and why
terry-form-mcp-expert 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 12d 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.

Skill Metadata
- Version: 1.0.0
- Last Updated: 2026-03-04
- Project: Terry-Form MCP
- Skill Path: .claude/skills/terry-form-mcp-expert/SKILL.md
Purpose & Invocation
This skill makes the AI assistant an expert in everything about the Terry-Form MCP project. It should be loaded at the start of every session by referencing this file.
Trigger phrases (any of these should cause the AI to load this skill):
- "start a session on terry-form-mcp"
- "load project context"
- "you are the terry-form-mcp expert"
- "what do you know about this project"
Session Start Protocol
When this skill is invoked, the AI assistant MUST:
- Read this file completely before responding to any task
- State which version of the skill was loaded and the last-updated date
- Summarize the project in 2-3 sentences to confirm context is loaded
- Ask the developer what they are working on today
- Check git status and git log --oneline -10 to understand current state
- Flag any known issues from the Gotchas section relevant to today's work
Project Overview
Terry-Form MCP is a production-ready Model Context Protocol (MCP) server that provides AI-powered Terraform execution within Docker containers. It exposes 25 MCP tools for Terraform operations (init, validate, fmt, plan), LSP-based code intelligence via terraform-ls, GitHub App integration, and Terraform Cloud connectivity. The server communicates via MCP stdio transport — there is no HTTP server, no web dashboard, and no exposed ports.
The project serves infrastructure teams that want to safely automate Terraform workflows through AI assistants like Claude Desktop. Security is the core design principle: destructive operations (apply, destroy) are permanently blocked, all file access is isolated to /mnt/workspace, inputs are sanitized against injection, and the container runs as a non-root user (UID 1001). Version 3.1.0 requires Python >= 3.10.
The documentation site at https://aj-geddes.github.io/terry-form-mcp is a Jekyll-based GitHub Pages site with a dark-first glassmorphism design, covering 10 guides, 6 tutorials, API reference for all 25 tools, and architecture documentation.
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.

terry-form-mcp-expert is a skill published in the GitHub repository aj-geddes/terry-form-mcp (10 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 5,180 tokens. 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.
