From 81a3513fd4ed577640d6afb711f8d405b45cc2bc Mon Sep 17 00:00:00 2001 From: data-engineer Date: Wed, 20 May 2026 09:46:41 -0700 Subject: [PATCH] feat(install): gradata uninstall --agent (GRA-1241 / epic GRA-1198) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds symmetric uninstall for every supported host: claude-code, codex, gemini, cursor, hermes, opencode (or --agent all). Reverses what gradata install --agent writes, with user-edit detection via SHA256 against the install manifest. Architecture: - New `_install_manifest.py` module: records (config_path, signature, sha256_after_install) per host at `~/.gradata/install_manifest.json` on every successful install. Idempotent record/get/drop helpers. - Each adapter grows `uninstall(brain_dir, config_path) -> InstallResult` symmetrical to its existing `install()`. Per-host config shape: - claude-code: hooks.PreToolUse[] (JSON) - cursor: mcpServers.gradata (JSON) - gemini: tools.preCall[] (JSON) - opencode: hooks.preTool[] (JSON) - hermes: hooks.pre_tool_call[] (YAML) - codex: [[hooks.pre_tool]] (TOML) - Shared helper `_base.uninstall_from_list_in_dict` for the 3 JSON list-shaped configs (gemini, opencode); hermes uses YAML so it has its own implementation; cursor/claude-code/codex are bespoke. - New CLI subcommand wired in cmd_uninstall: matches install's --agent choices, reads manifest record OR falls back to canonical config path for legacy installs, SHA256 check, dispatches to per-host uninstall. - Action type expanded to include 'removed' (was added|already_present|failed). - cmd_install now records to the manifest on every successful install. Preserves user customizations: if the config file's SHA differs from the recorded SHA, print 'skipped — modified since install' and leave it. Don't silently delete user changes. Idempotent: running uninstall twice returns 'already_present' on the second call. Empty containers (e.g. `hooks: {}`) are pruned. Test plan: pytest tests/test_uninstall_command.py => 11 passed in 0.44s 11 cases: round-trip for each of the 6 adapters, preserves user-owned entries, idempotent when never installed, missing config no-crash, manifest record_install/get_record/file_sha256 round trip, CLI clean error on unknown agent. Live smoke on oliver-admin: gradata uninstall --agent claude-code --brain /tmp/test-brain → ✓ claude-code → /home/olive/.claude/settings.json (already_present) Authoring note: started by a delegate_task subagent which hit max_iterations on the adapter changes; parent agent completed the 6 adapter uninstall() methods + tests + lint + ship. Closes GRA-1241.
