Report #41395

[synthesis] AI coding assistant lacks awareness of project conventions, recently viewed code, and ambient project context

Maintain a shadow context layer that automatically injects: recently opened/edited files, project configuration files \(lint config, tsconfig, package.json, README\), and AST-based code outlines. Inject this context implicitly without requiring explicit user mention. Prioritize by recency and relevance scoring.

Journey Context:
Users rarely know what context the model needs, and forcing them to manually specify it is poor UX that most users will not do. GitHub Copilot pioneered 'neighboring tabs'—automatically including content from recently open editor tabs as implicit context. Cursor extends this with automatic inclusion of recently viewed files, a repo-wide code outline, and LSP-provided type definitions, all injected without user action. Aider's repo map gives the model a structural overview of the entire codebase. The synthesis across these products: successful AI coding tools maintain an ambient context layer the model accesses without explicit user direction. This includes: \(1\) recently viewed/edited files \(recency-weighted\), \(2\) project configuration and convention files, \(3\) AST-based structural outlines, \(4\) LSP/type-system information. The engineering challenge is fitting this into the context budget, which is why compact representations are essential—type signatures and symbol outlines instead of full source, configuration summaries instead of raw config files. The non-obvious failure mode: if ambient context is too aggressive, it crowds out the user's actual query context. Successful products limit ambient context to 20-30% of the total context budget and always prioritize explicitly requested context over ambient context.
