…ory tools - Install now adds [mcp_servers.supermemory] to ~/.codex/config.toml - Uninstall removes the MCP server entry - Status command shows MCP server registration state - MCP endpoint: https://mcp.supermemory.ai/mcp - Provides explicit memory tools: memory, recall, listProjects, whoAmI - 4 new unit tests for MCP registration (install/uninstall/preserve)
When uninstalling on a config that never had mcp_servers, the code previously created an empty section. Now it only touches mcp_servers if it already exists, and removes the section entirely when empty.
src/cli.ts:
- Extract setMcpServer() helper so mergeConfigToml() reads as a pure
orchestrator (read → toggle feature → toggle MCP → write).
- Drop empty [features] section on uninstall (mirrors the cleanup we
already do for [mcp_servers]).
- Hoist the repeated Record<string, unknown> cast into a typed
getMcpServers() helper.
- Move MCP_SERVER_NAME / MCP_SERVER_URL up next to the other path/config
constants.
- Trim install message phrasing so it parallels the codex_hooks line.
- Status: include !mcpRegistered in the 'run install' trigger so users
upgrading from the previous version get prompted to reinstall.
- Don't clobber a user-customized supermemory MCP entry on install
(only register if the entry doesn't already exist), and only remove
on uninstall when the entry matches the exact installer-managed
shape ({ url: MCP_SERVER_URL }).
test/unit.mjs:
- Remove unused existsSync / homedir imports.
- Extract setupCodexHome(t) and runCli() helpers; cleanup now happens
in t.after() so failed assertions don't leak temp dirs.
- Parse config.toml with @iarna/toml and assert on the parsed structure
instead of substring-matching the serialized output.
- Verify the supermemory URL is correct in the merge-with-existing test.
- Add tests covering the new no-clobber behavior on install/uninstall
for user-customized supermemory entries.
- Add test asserting the empty [features] section is dropped on uninstall.
- Rename section to 'integration: install/uninstall MCP server registration'
to flag that those tests spawn the built CLI.
package.json:
- 'npm test' now runs 'npm run build' first so the integration tests
can find dist/cli.js on a clean clone.
Replace the remote mcp.supermemory.ai/mcp registration with a local stdio-based MCP server that reuses the same SupermemoryClient, config, and tags as the hooks. No separate auth needed — everything reads from SUPERMEMORY_CODEX_API_KEY. New files: - src/mcp.ts: stdio MCP server with memory, recall, listProjects tools Modified: - src/services/client.ts: add forgetMemory() and listProjects() methods - src/cli.ts: register stdio server (command+args) instead of HTTP URL - build.mjs: add mcp.ts build entry - package.json: add @modelcontextprotocol/sdk and zod dependencies - test/unit.mjs: update assertions for stdio shape, add MCP server tests 28/28 tests pass.

… forget) - Remove embedded stdio MCP server (src/mcp.ts) and dependencies (@modelcontextprotocol/sdk, zod) - Add three skill scripts: search-memory.ts, save-memory.ts, forget-memory.ts - Add three SKILL.md files for Codex auto-discovery - Update CLI install/uninstall/status for skills instead of MCP - Update build to bundle skill scripts and copy SKILL.md files - Update tests: remove MCP tests, add skill assertions This aligns with the Claude Code plugin pattern where skills are SKILL.md files + pre-compiled scripts, not MCP tools.
- Remove dead listProjects() from client.ts - Add 'project-knowledge' to MemoryType, drop double cast in save-memory - Fix forget to remove from both user and project scopes - Surface auth/network errors in search-memory instead of false 'No memories found' - De-duplicate build.mjs with entries array - De-duplicate cli.ts with SKILLS constant array - Drop unused spawn import from tests - Add exit code assertions to integration tests
Rename skill directories from super-search/super-save/forget to supermemory-search/supermemory-save/supermemory-forget to avoid collisions with other Codex plugins that might use generic names like 'forget'.

Comprehensive 63-test suite that exercises the full plugin flow: install, verify artifacts, status, save, search (all scopes), recall hook, capture hook, forget, error handling, uninstall, and idempotency — all against the live production API. Requires SUPERMEMORY_CODEX_API_KEY to run.

Summary
Complete
codex-supermemoryplugin that gives OpenAI Codex CLI persistent memory via Supermemory. Provides both implicit memory (hooks) and explicit memory (skills).Implicit Memory (Hooks)
UserPromptSubmit): Automatically injects relevant memories and user profile into every prompt asadditionalContextSessionStop): Ingests conversation transcripts into Supermemory, storing memories in both project and user containersExplicit Memory (Skills)

memories.forget()API requires exact content match. When memories are ingested viaaddMemory, the content gets processed/chunked, so the stored representation may differ from the original input. This causesforgetto return 404. The skill code is correct — this is an API behavior. Recommendation: enhance forget to search-then-delete-by-ID for more reliable operation.Build Verification
