This skill should be used when a model gets read-write control over its own live context window instead of a harness-scheduled compaction policy: the context exposed as an editable file the model rewrites with code tools, model-driven eviction and in-place updates, the harness invariants that keep self-editing safe (pinned prefix, edit gate, edit receipts, budget readouts, rollback on overflow), the prefix-cache cost of mid-context edits, and steering or training the model's own context-editing…

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'self-managed-context' ] || [ -L ~/.agents/skills/'self-managed-context' ]; then echo 'A skill folder named self-managed-context already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/guanyang/antigravity-skills' "$d" && git -C "$d" checkout --quiet 'a6603bf9fa9acd6bf9c7cc2fa6273ad3faa1c3b6' -- 'skills/self-managed-context' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/self-managed-context' ~/.agents/skills/'self-managed-context' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'self-managed-context' ~/.claude/skills/'self-managed-context' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
