What technologies does it support?

It works for any software ecosystem including .NET, Node.js, React, Python, and various package managers.

How does this prevent hallucinations?

It blocks the AI from relying on its internal, potentially stale training data by forcing it to check external documentation first.

What is an epistemic checkpoint?

It is a mandatory pause in the AI's reasoning process to verify factual claims about versions and dates against real-time data before answering.

Can I customize the ground-truth sources?

Yes, you can define local facts in an assertions.yaml file which the skill prioritizes over general web searches.

When does this skill activate?

It triggers automatically whenever a prompt mentions 'current,' 'latest,' specific version numbers, or release statuses.

Developer Tools

Eliminates hallucinations by forcing real-time verification of software versions, release statuses, and dates before providing technical answers.

Epistemic Checkpoint acts as a metacognitive guard for Claude, preventing root-cause hallucinations where the model relies on stale training data. It enforces a mandatory verification protocol that triggers whenever a query involves package versions, API deprecations, or current release statuses. By checking local ground truth in a blackboard file or performing targeted web searches of official documentation before forming a belief, it ensures that Claude’s reasoning is grounded in the latest technical reality rather than outdated memory.

Key Features
