Context Window Bloat Is an Agent Cost Problem
Large workspace files and stale tool output silently increase the cost of every agent heartbeat, triage run, and background task.
Quick answer
Context bloat is recurring spend. Every extra instruction file, memory note, and stale tool result can be reloaded across heartbeats and background jobs.
Why it compounds
A thousand extra tokens is not expensive once. It is expensive when it rides along with every scheduled check, every status update, and every small automation task.
Common sources
- large memory files that should have been distilled
- duplicated repo instructions
- verbose task prompts copied into cron jobs
- tool output kept in context after it stops being useful
- background agents using main-session context for tiny checks
Measure before trimming
Do not guess. Track input tokens by workflow and compare similar runs before and after pruning. The useful number is not file size, it is repeated input cost.
How Clawback helps
Clawback is built to show which workflows are carrying too much context and how much that context costs over time.
FAQ
Should I delete memory?
No. Distill it. Keep durable decisions, remove raw noise, and move large artifacts into files the agent opens only when needed.
Is caching enough?
Caching helps, but it does not fix bad prompt hygiene. Smaller repeated context is still better.
What should I trim first?
Duplicated instructions and stale logs that are loaded every run.
