All notable changes to Myco are documented here. Format follows Keep a Changelog; the project adheres to Semantic Versioning.

1.2.0 - 2026-06-23

Headline

Node-free native installer. Myco now ships as a self-contained native binary — no Node runtime is required to run it. curl -fsSL https://myco.sh/install.sh | sh (macOS/Linux) and irm https://myco.sh/install.ps1 | iex (Windows x64) download the binary to ~/.myco/bin (%LOCALAPPDATA%\Myco\bin on Windows), register a managed per-user service, and connect supported agents. npm install -g @goondocks/myco still works as a thin bootstrap that converges to the same native binary.

Added

  • Single-binary self-update. The local service keeps itself up to date from its release channel in the background while idle. Upgrades can also be triggered from the Upgrade section of the dashboard's Settings page or with the new myco upgrade CLI (--channel stable|beta). npm update is no longer part of the main upgrade path.
  • Daemon coexistence. A development Myco service can run alongside the released production service on the same machine — variant-aware Grove binding keeps their Groves, services, and upgrades isolated.
  • Cross-platform service lifecycle. Managed per-user service install and supervision across launchd (macOS), systemd (Linux), and Task Scheduler (Windows), validated on macOS, Linux, and Windows x64.

Changed

  • Install no longer requires Node. The installer downloads a native binary instead of installing the npm package. Node 22+ is now needed only for the optional npm install path and the operator CLIs (@goondocks/myco-team, @goondocks/myco-collective).
  • Platform support: macOS is the primary supported platform; Linux and Windows are in beta. Windows is x64 only — Windows on ARM is not supported.

Unreleased

Headline

Zero-config global install. Install once, every project works. myco init is no longer required (or available as a bare command) — the service auto-registers during npm install -g, the daemon auto-starts, and projects are auto-registered to a default Grove on the first agent hook.

Added

Global symbiont install architecture

  • All 8 symbionts (Claude Code, Cursor, Codex, Copilot, Antigravity, Windsurf, OpenCode, Pi) install once at each agent's global configuration location, not per-project. Local .agents/ folders are no longer required.
  • Two global launchers — ~/.myco/launcher.cjs and ~/.myco/mcp-launcher.cjs — bridge every agent's hook + MCP system to the daemon. Project-local launchers can override per-project.
  • Capture buffer relocated under ~/.myco/buffer/ (per-Grove subdirectories). Legacy .agents/myco-buffer/ is archived during migration.
  • Per-project archives of prior .agents/ artifacts are written on migration — auditable and restorable, but inert.
  • Project overrides moved to the dashboard's Symbionts page. Disable/enable a symbiont in a specific project via UI rather than CLI flags.
  • New manifest fields: detectionDir, globalHooksTarget, globalMcpTarget (string or string[]), globalSettingsTarget.
  • Settings-merge for shared agent config files: Myco's hook/mcp/skills entries are upserted; user-pre-existing keys (e.g. Codex [features].hooks) are preserved across install/uninstall cycles.

Default Grove + auto-register projects

  • A default Grove is created at install. Projects auto-register into it on first agent hook — no myco init step. Hooks fired from non-git directories (cwd-fallback misfires) are silently skipped.
  • Users can create additional Groves and reassign projects between them through the dashboard.
  • Variant-aware Grove binding: dev daemons (MYCO_SERVICE_VARIANT=dev) bind only to Groves with served_by="service-dev"; prod daemons only to served_by="service". Dev and prod can coexist on the same machine — each gets its own default Grove. The previous prod-side escape hatch (default Grove regardless of served_by) is closed.

Antigravity symbiont (Gemini IDE successor)

  • New symbiont with full CLI + IDE + app surface coverage.
  • PreInvocation transcript-read for user-prompt capture.
  • PostInvocation spore injection with per-prompt deduplication.
  • Stop processor reconciliation invokes transcript re-enrichment for symbionts whose hooks lack prompt/summary data.
  • Launcher reads workspacePaths from stdin for multi-agent workspaces.
  • One-time data remap migrates legacy ~/.gemini/ artifacts and cleans stale trusted_hooks.json entries.

Unified injection-records helper

  • recordInjectionActivity() is the single injection path for Cortex, Spores, and Canopy. UNIQUE-index dedup, log-payload scrubbing (no injected_text in INFO logs), recordInjectionAndShouldSuppress() wrapper for unified call sites.
  • Cortex injection gated on AGY's invocationNum === 0 — fires only once per session start.
  • Distinct UI rendering for myco:* injection activity rows.

Daemon state authority

  • DaemonStateAuthority is the only path for daemon.json mutation. Raw writeOrTouchDaemonState is no longer reachable. Every write logs reason, caller-pid, and before/after PID.

Sandbox-safe service install

  • New MYCO_LAUNCH_AGENTS_DIR env var lets sandboxed test installs target a non-default LaunchAgents/systemd-user directory.
  • Sandbox installs get a label suffix (co.goondocks.myco-dev.sandbox-<8hex>) so they cannot collide with canonical service registrations.
  • MYCO_LAUNCH_AGENTS_DIR is propagated into the plist EnvironmentVariables block so child daemons spawned by RunAtLoad: true inherit the same sandbox context.
  • Production behavior is byte-identical when the env var is unset.

Symbionts page in daemon UI

  • Live status of every detected symbiont, with re-detect trigger.
  • Per-project override controls.

myco doctor expansions

  • Detects cursor-cd-cwd missing prefix, Claude-matcher emptiness, hybrid-TOML state, project-local stub residue.
  • Surfaces migration audit log + service registration state.

myco remove and myco remove --purge

  • Clean removal of Myco's contributions to every agent's global config, preserving user-pre-existing keys.
  • --purge additionally removes ~/.myco/ itself.

Tests

  • New invariant test suites: launcher write-ordering, daemon-bound intent bypass, daemon rebind on first project, variant-aware rebind filter, canonical-plist-no-hijack, greenfield default-Grove + first-hook auto-register end-to-end.
  • MYCO_LAUNCH_AGENTS_DIR propagation regression tests in tests/service/.
  • Test isolation hardened: --isolate runner enforcement, MYCO_HOME sandboxing in beforeEach for relevant suites.

Changed

  • Default install path is global. npm install -g @goondocks/myco (or the install script) is the only step. No per-project setup required.
  • Symbiont rename: vscode-copilot → copilot, with multi-target MCP for Copilot CLI + IDE.
  • Claude Code hook templates now include matcher: "" in every hook group, enforced by invariant test.
  • Cursor hook commands now include cd ${CURSOR_PROJECT_DIR:-.} prefix; invariant test enforces a cd prefix on every global hook template for its agent's project-dir env var.
  • OpenCode MCP transport switched from relative-path stdio to remote/URL.
  • Windsurf manifest hookFields aligned with current Cascade payload schema.
  • License relicensed from MIT to Apache 2.0 on 2026-04-29 (commit 57a9571a). Marketing site and docs updated accordingly.

Removed

  • myco init CLI command — entirely. Both the bare invocation and the --project <path> form. Project setup is fully automatic on global install; per-project overrides (portable Grove identity, dogfood binary pinning, project-local launcher) move to the dashboard's Symbionts page.
  • --worktree flag.
  • Per-project .agents/myco-buffer/ location (replaced by ~/.myco/buffer/, with migration archive in each project).

Fixed

  • Limit-cap saturation in syncTranscriptPromptBatches (event-handlers.ts): swapped listBatchesBySession (capped at 200) for countBatchesBySession + insertBatchStateless, wrapped in db.transaction() for fsync win.
  • React Hooks violation in ActivityList.tsx: useState was called after an early return for MycoInjectionItem; dispatch moved to parent component.
  • Codex [features].hooks data loss on myco remove: audit-track TOML settings preserves user-pre-existing keys.
  • Brownfield walker orphan stubs: walker now cleans up unregistered legacy projects (was registry-driven only).
  • Cross-Grove walker boundary: enforced via served_by filter (R3.0). Audit pass on all listGroves() callers.
  • TOML upsert newline bug in buildTomlMcpSection.
  • /api/symbionts/detect entry point now calls runGlobalBootstrap, not runSymbiontDetection.
  • Layered launcher path resolution: runtime.command dispatch correctly resolves project-local override → global launcher → daemon binary.
  • Atomic writes for every agent-config write (was inconsistent across symbionts).
  • Canopy mass-delete bug: walker scope correctly differentiates project root vs grove root.
  • Daemon-bound installGlobalLaunchers infinite no-op: added skipIntent parameter so the reconciler can bypass its own intent-routing.
  • MYCO_LAUNCH_AGENTS_DIR not propagated to launchd child daemons: caused the canonical ~/Library/LaunchAgents/co.goondocks.myco-dev.plist to be overwritten during sandbox installs. Fix propagates the env var through the plist EnvironmentVariables block.
  • Stop processor empty-named buffer events no longer overwrite parser breakdown.
  • prompt_count / tool_count drift in sessions: now derived from row scans.

Security

  • All migration writes go through audit logging (bounded). Migration completion surfaces a notification with audit-trail summary.

Notes for upgraders

From v0.25.x (or earlier)

If you have an existing per-project .agents/ install in a project:

  1. Upgrade Myco globally: npm install -g @goondocks/myco@latest.
  2. The daemon restarts and runs the migration walker on next start.
  3. Per-project .agents/ artifacts are archived in-place; agent global configs are updated to point at the new global launchers.
  4. The Symbionts page in the dashboard shows the new global install state.

No myco init invocation needed. Run myco doctor after upgrade to validate.

From per-machine MIT-era installs
