Cleanup Artifacts & Session Hygiene

Use this skill after task implementation and verification are complete, when the user requests or confirms cleaning up session bloat across agent harnesses (Antigravity, Claude Code, Codex, OpenCode/Aider).

Principles

1. User Confirmation Required: Never purge conversation histories, scratch files, or caches without explicit user intent.
2. Preserve Rules, Agents, MCPs & Projects: Never remove configuration files, rules, custom agents, MCP tool schemas, database migrations, or project repositories.
3. Preserve Active Session: If operating inside an active agent conversation, preserve the active session ID's brain and transcript.

Targets by Harness

1. Antigravity

• Past Conversations: Purge inactive conversation databases in %USERPROFILE%\.gemini\antigravity\conversations\.
• Inactive Brains: Purge non-active UUID folders in %USERPROFILE%\.gemini\antigravity\brain\.
• Temporary Tool & Browser Traces: Purge %USERPROFILE%\.gemini\antigravity\browser_recordings\*, cache\*, artifacts\*, implicit\*, and sidecar_data\*.
• Installers & Staged Updates: Purge %LOCALAPPDATA%\Temp\antigravity-stable-user-x64 and %LOCALAPPDATA%\antigravity-updater\*.
• Web & GPU Caches (Deep Clean): Optionally flush Cache, Code Cache, GPUCache, and CachedData inside %APPDATA%\Antigravity and %APPDATA%\Antigravity IDE.

2. Claude Code

• Caches & Transcripts: Clear inactive sessions in ~/.claude/artifacts/, ephemeral scratchpads, and debug log files.
• Preserve: Keep ~/.claude/settings.json, configured skills, and authenticated profiles.

3. Codex & OpenCode / Aider

• Scratch & Diffs: Purge stale patch chunks (.patch, .diff.tmp), transient tool logs, and cached completions in .codex/cache/ or .opencode/.

4. Workspace Level

• Purge intermediate scratch test scripts (scratch/*.ps1, scratch/*.py) created solely for one-off debugging.
• Purge standard build/test cache directories generated during task verification (e.g., .pytest_cache, .coverage, __pycache__, node_modules/.cache) when confirmed.

Workflow

1. Assess & Report: Check current file counts and sizes in the relevant harness locations. Present the summary to the user.
2. Confirm Scope: Clarify whether to run standard cleanup (session data, past artifacts, temp files) or deep cleanup (including IDE/browser GPU caches).
3. Execute: Remove the target paths cleanly using non-interactive commands.
4. Report Outcome: Output a before-and-after reclaimed disk space summary.
