Context Engineering

Context engineering strategies for AI agents: write, select, compress, and isolate context to optimize performance and manage long-running tasks.

Semantic Compression

An introduction to the idea that code should be approached with a mindset towards compressing it semantically, rather than orienting it around objects.

The Architect of Constraints: Why Context Engineering Is the Human Skill That Matters

Unifying fold left and fold right with Prolog

Here's a rather cool trick we noticed during a recent discussion in the NUS PLSE Lab.1

Coeffects: a calculus of context-dependent computation

The notion of context in functional languages no longer refers just to variables in scope. Context can capture additional properties of variables (usage patterns in linear logics; caching requirements in dataflow languages) as well as additional resources or properties of the execution environment (rebindable resources; platform version in a cross-platform application). The recently introduced notion of coeffects captures the latter, whole-context properties, but it failed to capture fine-grained per-variable properties.We remedy this by developing a generalized coeffect system with annotations indexed by a coeffect shape. By instantiating a concrete shape, our system captures previously studied flat (whole-context) coeffects, but also structural (per-variable) coeffects, making coeffect analyses more useful. We show that the structural system enjoys desirable syntactic properties and we give a categorical semantics using extended notions of indexed comonad.The examples presented in this paper are based on analysis of established language features (liveness, linear logics, dataflow, dynamic scoping) and we argue that such context-aware properties will also be useful for future development of languages for increasingly heterogeneous and distributed platforms.

Invisible details - Building contextual menus - Linear

We recently added contextual menus to Linear. This makes the app faster and easier to use for people who prefer their mouse. One small thing that you won’t see or think about but will hopefully feel is a detail we designed into how sub-menus work.
