Keep the agent's context lean so accuracy doesn't collapse. Use on long sessions, big files, or when the agent starts hallucinating.
Installation
Install with Codex or Claude Copy this prompt, paste it into Codex, Claude, or another assistant, and let it review the skill page and install it for you.
More context is not better. Past a threshold, accuracy falls off a cliff (context rot).
Don't dump whole files - read the relevant function/section, not the 2000-line module.
Summarize, don't accumulate - replace a 200K-token transcript with a 4K recap of the load-bearing facts.
Drop dead context - once a sub-task is done, its detail leaves the window. Keep the decision, drop the trace.
State on disk, not in context - progress goes to a file the next turn re-reads, not into an ever-growing prompt.
A bloated standing context file taxes every single turn. Trim weekly. If the agent is confidently wrong, suspect the context before the model.
