Jakub Zych 6cfa0c55d2 refactor: drop 12 runtimes, keep Claude, Codex, OpenCode, Cursor, ZCode, Antigravity

Removes kilo, kimi, kimi-code, copilot, windsurf, augment, trae, qwen, hermes,
cline, codebuddy and pi end to end: capability descriptors, installer branches
and converters (bin/install.js 14.9k -> 11.2k lines), TypeScript converters,
hook surfaces and runtime homes, review lanes qwen/kimi-code, the two pi
migrations, Kimi payload normalization in the hook guards, dead hostBehaviors
vocabulary, launcher home probes, fixtures, runtime-specific tests and the
prose that presented them as supported.

Installer output for the six kept runtimes is byte-identical to before the
prune. The Kimi tool-vocabulary tests in workflow-guard, read-guard and
read-injection-scanner are left in place pending a decision.

36	Multi-Runtime Support	Infrastructure Features

Purpose: Run MSD across multiple AI coding agent runtimes.

Requirements:

REQ-RUNTIME-01: System MUST support Claude Code, OpenCode, Codex, Antigravity, Cursor
REQ-RUNTIME-02: Installer MUST transform content per runtime (tool names, paths, frontmatter)
REQ-RUNTIME-03: Installer MUST support interactive and non-interactive (--claude --global) modes
REQ-RUNTIME-04: Installer MUST support both global and local installation
REQ-RUNTIME-05: Uninstall MUST cleanly remove all MSD files without affecting other configurations
REQ-RUNTIME-06: Installer MUST handle platform differences (Windows, macOS, Linux, WSL, Docker)
REQ-RUNTIME-07: Runtimes with lifecycle hook support MUST register per-turn context-headroom tracking events at install time
REQ-RUNTIME-08: Native packaging manifests MUST be version-stamped and enable runtime-native install/update/uninstall flows

Runtime Transformations:

Aspect	Claude Code	OpenCode	Codex	Antigravity	Cursor
Commands	Slash commands	Slash commands	Skills (TOML)	Skills	Skills + Slash commands
Agent format	Claude native	`mode: subagent`	Skills	Skills	Skills
Skills emission	N/A	On-demand SKILL.md (1.4.0)	`/skills` picker (1.4.0)	N/A	SKILL.md
Hook events	`SessionStart`, `PreToolUse`, `PostToolUse`, `SubagentStop`, `Stop`, `PreCompact`, `FileChanged`	N/A	`SessionStart`, `SubagentStart`, `Stop`, `PostToolUse`	N/A	`sessionStart`, `postToolUse`
Config	`settings.json`	`opencode.json(c)`	TOML	Config	Config

Cursor artifact surfaces: msd install --cursor writes two artifact kinds:

~/.cursor/skills/msd-<name>/SKILL.md — rich skills with YAML frontmatter, Cursor tool-name mapping, and adapter context header (existing surface)
~/.cursor/commands/msd-<name>.md — plain markdown slash commands (no frontmatter) invocable via / in the Agent input (Cursor 1.6+)

Native skills emission (1.4.0): One runtime now emits MSD as on-demand native skills (skills/<name>/SKILL.md) at install time, in addition to their existing command and agent surfaces. Skills respect the active install profile and are removed on uninstall.

OpenCode — emits skills alongside its existing surfaces

New slash-command surfaces (1.4.0):

Cursor (Cursor >= 1.6) — .cursor/commands/msd-<name>.md so MSD appears in the / command menu

Cross-runtime lifecycle hooks (1.4.0): Each supported runtime registers lifecycle hook events for per-turn context-headroom tracking and workflow state management. Notable registrations:

Claude Code: SubagentStop, Stop, PreCompact (context-headroom warnings), FileChanged (hot-reloads .planning/config.json mid-session)
Codex: SubagentStart, Stop, PostToolUse (new in 1.4.0); on Windows the SessionStart hook entry gains a commandWindows field so the .cmd shim is used for native execution
Cursor: sessionStart (injects workflow state), postToolUse (nudges .planning updates)

Runtime-specific enrichments (1.4.0):

Codex emits service_tier: flex for light-tier agents; MSD skills appear in the Codex /skills picker via SKILL.md (no agents/openai.yaml sidecar is emitted — doing so caused duplicate autocomplete entries, #1326)

Native packaging:

Claude Code: MSD Core ships a .claude-plugin/plugin.json manifest, enabling installation and lifecycle management via claude plugin install|enable|disable|update msd-core. Commands load under the /msd-core: namespace (e.g. /msd-core:plan-phase), avoiding slash-command collisions with the classic npm installer which uses /msd:. Always-on guard and update hooks are wired automatically via hooks/hooks.json. The plugin path is additive — the npm installer (npx @golem15/msd-core) remains fully supported.
