Testing CIMD support across Anthropic's Claude products

The article tests whether Anthropic's Claude products support CIMD (Client-Instructed Model Deployment), examining how different Claude variants handle this feature and documenting the results across various deployment interfaces.

Background

- CIMD (Computer-Implemented Mathematical Definition) is a notation system used to formally define mathematical concepts in a machine-readable way. It's relevant to AI alignment and reasoning research. - This article tests whether Anthropic's Claude (a large language model / AI assistant) correctly handles CIMD notation across different product tiers (free vs. paid, web vs. API). - Anthropic is the AI company behind Claude. They have multiple product versions — Claude Instant (faster/cheaper), Claude 2 (more capable), Claude Pro (subscription), and API access for developers. - The background context: AI developers often need models that can handle specialized formal notations (math, code, logic). Testing across tiers reveals capability gaps between free and paid offerings.

    Newer Claude models sometimes invent extra keys in tool call arguments, breaking validation in Pi's edit tool. The author suspects post-training for Claude Code's forgiving harness makes alternative schemas fail. This suggests closed RL training can degrade general tool-use reliability.

    Simon Willison released llm-coding-agent 0.1a0, an experimental coding agent built on his LLM library. The agent provides tools for reading, editing, searching files and executing commands, and ships with a Python API and CLI. It was developed using Claude Code (Fable 5) via TDD with a spec-first approach, and is available as a slop-alpha on PyPI.
