One recommendation would be to create a skill (name_of_your_internal_tool/SKILL.md) describing how the agent should use the tool(s) you're working with. This allows you to progressively disclose that context to the agent rather than filling its context (via its system prompt) with those instructions on every turn. If you use Claude Code, you can also try using it to interactively create the skill (it has a `skill-creator` skill). On the specific skills to make, you could align it with the specific tool (e.g., "Read this skill whenever the user asks you to use X tool...") or with a particular action (e.g., "Read this skill whenever the user asks you to [write, create, etc.]..."

The particular issue arises with the models from other providers, but thanks for the suggestion, it's helpful.

Yes, and that's one of the reasons I started working on this tool: to elicit desirable behavior from AIs before turn 1. AI is still non-deterministic and won't follow instructions 100% of the time, but with this tool, I intend to narrow that gap.

Would love to hear your thoughts on it: https://github.com/turnzero-ai/turnzero
