Can I use Ctx to share information between different projects?

Yes, Ctx supports project tags, allowing you to store cross-project knowledge that can be recalled regardless of which repository you are currently working in.

How does Ctx differ from the standard MEMORY.md?

While MEMORY.md is best for brief, project-scoped notes, Ctx is a structured knowledge graph that supports metadata, different data types (like hypotheses or patterns), and tiered loading to save context tokens.

Will Ctx bloat my context window usage?

No, Ctx uses a tiering system. Only 'pinned' and 'working' information is automatically loaded, while 'reference' and 'off-context' data is only retrieved when explicitly queried.

Is the memory storage automatic?

The skill includes hooks that run at the start and end of sessions, but the AI is instructed to actively emit storage commands whenever a significant decision or discovery is made.

개발자 도구

Implements a structured, multi-tiered persistent memory system to retain decisions, patterns, and facts across Claude sessions.

The Ctx skill provides a sophisticated persistent memory layer for Claude, moving beyond basic file-based notes to a structured knowledge graph. By utilizing specialized XML-style commands, it allows Claude to categorize information into tiers—ranging from critical pinned facts to temporary working context. This ensures that architectural decisions, debugging observations, and user preferences are never lost between stateless sessions, effectively creating a long-term 'brain' for complex, multi-day development projects and cross-project knowledge management.
