* Overview
|
|
|
|
The Context Manager provides stack-based project focusing. When the agent
|
|
"focuses" on a project, file paths resolve relative to it and memory queries
|
|
auto-filter by scope. This enables the agent to work within a bounded context
|
|
without being distracted by unrelated memory.
|
|
|
|
The core provides the mechanism (=memory-object-scope=, =context-query= with
|
|
scope parameter). This skill provides the policy — what to focus on, what
|
|
scope means for each project, and how the stack is managed.
|
|
|
|
** Contract
|
|
|
|
1. (push-context &key project base-path scope): pushes a context plist
|
|
onto ~*context-stack*~. Blocks if depth exceeds ~*context-max-depth*~.
|
|
2. (pop-context): pops and returns the top context. If the stack would
|
|
become empty, inserts a default memex-wide context instead.
|
|
3. (current-context): returns the top-of-stack context plist.
|
|
4. (current-scope): returns the ~:scope~ keyword from the current context.
|
|
5. (current-project): returns the ~:project~ name from the current context.
|
|
6. (current-base-path): returns the ~:base-path~ from the current context.
|
|
7. (context-stack-depth): returns the number of contexts on the stack.
|
|
8. (focus-project name base-path): pushes a new context for the named
|
|
project. Sets ~*scope-resolver*~ to return ~:project~.
|
|
9. (focus-session): pushes an ephemeral context for the current session.
|
|
10. (focus-memex): pushes a global memex-wide context.
|
|
11. (unfocus): pops one level from the context stack.
|
|
12. (resolve-path path): resolves a path relative to the current base-path.
|
|
13. (context-scoped-query &key tag todo-state type): queries memory filtered
|
|
by the current context's scope.
|
|
14. (context-save): persists the context stack to disk.
|
|
15. (context-load): restores the context stack from disk on startup.
|
|
