MICA v0.1.8 Formalizes the 'README-as-Protocol' Pattern
This article discusses the latest updates to the MICA (Memory Invocation & Context Archive) governance schema for AI context management, including the introduction of a 'fail-closed gate' for scoring and the formalization of the 'README-as-Protocol' pattern.
Why it matters
These updates to MICA help formalize the governance of AI context management, improving the reliability and transparency of how AI systems interact with their environment.
Key Points
- 1MICA now has a structured scoring policy with 'fail-closed' admission rules
- 2The 'README-as-Protocol' pattern formalizes how an AI session should load and confirm the MICA archive
- 3New features include the Invocation Protocol, Session Report Format, and Self-Test Policy
Details
The article covers the evolution of the MICA schema, focusing on versions 0.1.7 and 0.1.8. In v0.1.7, the scoring system was made more structured, with a defined policy for weighting different scoring dimensions. Importantly, a 'fail-closed gate' was introduced, which excludes context items that fail to meet certain thresholds, regardless of their scores on other dimensions. This addresses a key gap identified in previous versions. In v0.1.8, the 'README-as-Protocol' pattern was formalized, where the AI session's natural behavior of reading the README first is now the primary invocation mechanism. This is accompanied by new requirements like the Invocation Protocol, Session Report Format, and Self-Test Policy, which ensure the AI session can properly load and validate the MICA archive.
