What is claude-transformatron-9000 AGENTS.md?

Repository instructions for coding agents working on claude-transformatron-9000. The project is a local control system and command-line tool for starting and running one Maltego transform server.

They help agents operate the server, follow the transform-authoring rules, and use the documented development loop and verification steps.

They explain the project's purpose, required preparation before editing transforms, and the checks agents should follow while working.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01357	$0.01357
Opus 5.5	$0.00543	$0.00543
Sonnet 5.5	$0.00271	$0.00271
Haiku 4.5	$0.00136	$0.00136

Security

Grade A, and why

claude-transformatron-9000 AGENTS.md 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 2mo 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.

Agent guide

Instructions for coding agents working in this repository. This is the canonical file — CLAUDE.md points here. It follows the AGENTS.md convention, which Codex, Gemini CLI, and other agents read directly.

Humans: README.md is the friendlier entry point, but nothing here is agent-only.

What this project is

An MCP control plane and CLI for a single local Maltego v3 transform server. It handles the server lifecycle and transform execution. It does not help you write transform code.

Before writing a transform

Read docs/transform-authoring.md first. It documents two SDK behaviours that fail silently — code that looks right, runs green, and produces nothing. The vendored SDK guidance in server/.agents/skills/ teaches one of them.

Claude Code loads the same checklist automatically from .claude/skills/maltego-transform-author/SKILL.md. That file is a thin pointer to docs/transform-authoring.md, not a second copy, so nothing here is Claude-only. Working through this file instead gets you the same result.

The short version, in the order these bite:

Return a list, never a MaltegoGraph — a returned graph is silently discarded.
Annotate both the first parameter and the return type; a bare -> list publishes output NONE.
Import the module in server/project.py, or it never registers.
Check the entity count. A success state is not proof of anything.
Credentials belong in TransformSetting(auth=True, is_global=True), never hardcoded.
Validate input_entity.value before putting it in a URL or a subprocess call.

The loop

Add or edit a module under server/transforms/.
Import it in server/project.py — the server only registers what project.py imports.
Restart the server.
Confirm it registered, then run it.

Driving the server

Two interchangeable front ends over the same transformatron.operations module. Use whichever your tool supports.

CLI — works anywhere you can run a command:

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.
