task: Editor / agent / MCP-client integration (6 issues)

[DeusData]

Scope

Umbrella tracker for editor / agent / MCP-client integration bugs that aren't covered by an existing per-agent install. Includes install-target compatibility (AlmaLinux), process lifecycle, MCP handshake edge cases, and requests for new agent targets.

Sub-issues

• Impossible to install on AlmaLinux 9.7 #182 — Impossible to install on AlmaLinux 9.7 — FIXED (static Linux binaries since 0eba6df, shipped v0.7.0; no glibc/GLIBCXX dependency)
• codebase-memory-mcp.exe running after quitting VS Code. #185 — codebase-memory-mcp.exe running after quitting VS Code — awaiting reporter v0.7.0 retest (no parent-death watchdog today; asked for details)
• Cursor IDE not being discovered in installation/update #222 — Cursor IDE not being discovered — FIXED (f88d031: Cursor detection + ~/.cursor/mcp.json install/uninstall)
• initialize handshake fails when client sends a string JSON-RPC id #253 — initialize handshake fails on string JSON-RPC id — FIXED (4abcaa4: string ids preserved verbatim through parse→response)
• feat: add Codex SessionStart reminder hook for codebase-memory tool discovery #330 — feat: Codex SessionStart reminder hook — tracked enhancement (accepted; feature, not a bug)
• Support for antigravity cli? #366 — Support for antigravity cli? — DONE (already implemented: detection + ~/.gemini/antigravity/mcp_config.json install/uninstall)

Status (2026-05-31)

4 of 6 resolved (#182, #222, #253 fixed; #366 already shipped). Remaining: #185 (awaiting reporter retest on v0.7.0) and #330 (accepted enhancement, tracked separately). The bug surface of this group is closed; the two open items are a reporter-dependent retest and a feature request.

Acceptance

1. AlmaLinux / RHEL-family install path verified — static binaries remove the glibc dependency. ✅
2. Process lifecycle: server exits cleanly when parent terminates — open (codebase-memory-mcp.exe running after quitting VS Code. #185, pending retest).
3. JSON-RPC id accepts string and integer values per the spec. ✅
4. New agent targets (Codex hook, antigravity) decided in/out of scope — antigravity in (done); Codex hook accepted as tracked enhancement (feat: add Codex SessionStart reminder hook for codebase-memory tool discovery #330).

Why one task

These are all "the integration surface broke for X agent / X distro". The fixes touch cli.c install paths + the MCP server handshake — same surface area.
