Managing what occupies a model's context window, including the cost of tool names, descriptions, schemas, enums and constraints.
Model-written firmware compiled first try, flashed clean, and put colored noise on the panel because the cropped glass needs a drawing-window offset that only the vendor's wiki documents. A new repo packages that fact per board.
Reality
A Red Hat engineering post argues the cost of writing code has collapsed while the cost of reviewing, validating, integrating and maintaining it has not, and its fix is a threshold each developer has to spot mid-task.
Reality
The Copilot team put a token-shortening utility through its agentic benchmarks, watched task cost rise even as individual responses shrank, and shipped a compressor that only touches install, build, test and progress output.
Reality
MCP calls resources application-controlled because the mental model is a human attaching a file. Wrapping them as synthetic client-side tools fixes the context bloat and quietly relocates the gate that designation implied.
Reality
Google Research argues the weeks in geospatial modelling go into curation rather than modelling, and that an agent can absorb them. The engineering worth copying is that the orchestrating model plans over pointers and never reads the data.

The tell in a 1,039-line refactor was not a missing feature but a hand-rolled substring scan with a comment defending it. go-modern-guidelines gates its advice on your go.mod.
Reality
A developer measured 111,713 tokens of JSON schema from 10 MCP servers, injected before the first message, and priced the year at $1,764 per seat. The per-server number is the useful one.
Reality
A Go admin framework changed its module pattern; the models still write the old one, because the old one was public for longer. The permission wiring fails with no error at all.
Reality
One team cut its agent context file to 34KB without deleting a single rule, then wired a size check and a structure test so it cannot quietly regrow.
Reality
An essay on dev.to argues that pasting runbooks and standards into every agent session is a platform capability nobody has claimed, and that the bill grows as AI adoption succeeds.
Reality
A dev.to writeup argues large agent tool surfaces should collapse into a few domain routers with an action discriminator. The pattern is sound; the post ships no measurements.
