context compression
context compression is the term for Making working context smaller while keeping the facts and links a task needs. You can spot context compression in practice when the record shows what the system observes, what choice it makes, and what changes next, without asking the reader to guess or trust a slogan.

Why does context compression matter?
Compression makes room in the context window. A weak summary may drop a fact that a later choice needs. For context compression, start with three checks: What is kept, and for how long? Who can write or retrieve it? How would bad data be found and removed? The answers should point to visible evidence, not a promise.
What does context compression look like?
An agent turns fifty tool notes into a dated list of choices, open issues, and source links. This example makes context compression visible by naming the actor, the action, and the result in practice. It is an illustration for readers, not a claim that every product behaves this way.
What is context compression easy to confuse with?
Context compression trims current work. Memory consolidation turns short-lived records into lasting memory. The closest entries here are context caching, context engineering, working memory. Compare their definitions with context compression before using the names as if they mean the same thing. That comparison keeps context compression separate from nearby ideas without pretending the boundary is always perfect.
How certain is this definition?
This definition is provisional. ACL Anthology supports the version you see today, but a better or more direct source may change it. Open the cited page and check its date before you use this entry to choose a product, write a policy, set a safety control, or design a system.
Who introduced the term context compression?
We have not verified who first introduced context compression. The source supports a useful definition, but it may not be the earliest use. Until a dated primary record settles the question, we leave the origin open. A popular article or product page is not enough to name the person who coined a term.
What should you understand before context compression?
Read memory first when context compression depends on a more basic idea or mechanism. The link gives you a useful route through the glossary. It does not mean every author teaches the subject in this order, so follow the source when the sequence matters.
What should this term help you answer?
Use context compression to ask what an agent can observe, decide, change, remember, or hand off. The questions below turn the definition into a practical check. They are prompts for your own work, not claims made by the source, so change them to fit the system you are examining.
- What is kept, and for how long?
- Who can write or retrieve it?
- How would bad data be found and removed?
