alive:demo -- generative demo-world skill

This is the router. Route on $ARGUMENTS[0] to a sibling .md file (when present) or to the interactive create flow. Six subcommands + an interactive default:

All five non-create sibling .md files (list.md, activate.md, deactivate.md, delete.md, status.md) invoke their CLI subcommand under $ALIVE_PLUGIN_ROOT/bin/alive demo <name> and print the CLI's rendered_block field verbatim. create.md is the custom-path orchestrator: it walks Stage 0 -> Stage 1 hand-off -> Stage 2/3/4/5 driver chain end-to-end. The interactive default below routes the human into either the preset path or create.md based on their pick.

The router emits bordered blocks INLINE as markdown — matches the convention in plugins/alive/skills/world/SKILL.md and plugins/alive/skills/save/SKILL.md. There is no Python render_block bridge: the LLM emits its own markdown; only the CLI uses lib.format_block (per the codex review which rejected forcing LLM formatting from Python).

User choices use AskUserQuestion, never inline 1. / 2. / 3. answer text. Numbered options inside a bordered block are advisory; the actual decision flows through the question tool.

State + paths (canonical)

$ALIVE_DEMO_BASE_DIR is the only env override the demo skill reads. It controls where promoted worlds (<base>/wld_<ulid>/) and in-flight partials (<base>/wld_<ulid>.partial/) live. The state file and the world-root pointer stay canonical so the existing system-wide readers (_common.py, alive-common.sh, world/SKILL.md) keep working unchanged.

Router — interactive default (/alive:demo with no args)

When invoked with no subcommand, render this block inline and dispatch via AskUserQuestion:

╭─ 🐿️ /alive:demo
│
│   No demo subcommand given. Two paths:
│
│    1. preset       (sandbox-testing, deterministic, ~10s)
│    2. custom       (persona-driven, LLM-backed, ~1-2 min)
│
│   What would you like to do?
╰─

Then:

• AskUserQuestion with options Preset (sandbox-testing), Custom (persona-driven), Cancel.
• On Preset -> the "Preset path (sandbox testing)" section below; the squirrel calls alive demo preset run --preset realistic-seeded after the activation pre-check confirmation.
• On Custom -> jump into create.md (sibling of this file). create.md owns the persona intake, partial-dir mint, Stage 0 driver loop, Stage 1 hand-off to anchor_confirm.md, and the Stage 2/3/4/5 driver chain end-to-end.
• On Cancel -> render the cancellation block and stop:

╭─ 🐿️ cancelled
│
│   No demo world created. Run /alive:demo again any time.
╰─

When routing to create.md, render this one-line cue inline before jumping in so the human sees the routing decision:

> routing to create.md (custom persona path)

Subcommand routing

The CLI is the only path that touches demo-state.json and the world-root pointer. Each subcommand below shells out to $ALIVE_PLUGIN_ROOT/bin/alive demo <name> and prints the CLI's rendered_block field verbatim. Sibling .md files carry the per-subcommand UX detail; SKILL.md keeps the per-subcommand entry points short.

list

Routes to list.md. Prints a 6-column bordered-block table of every promoted demo world plus partial generations. Active world is flagged with *active in the STATUS column.

$ALIVE_PLUGIN_ROOT/bin/alive demo list

See list.md for envelope shape and error handling.

activate <ref>

Routes to activate.md. Resolves <ref> via 3-step fallback (exact label, ULID prefix, ambiguous-match envelope), runs the activation pre-check, and (with --confirm) runs the tail of the Stage 5 transaction (build-log refresh + step 10 demo-state staging + step 11 world-root commit) against the existing world.

$ALIVE_PLUGIN_ROOT/bin/alive demo activate <ref>
$ALIVE_PLUGIN_ROOT/bin/alive demo activate <ref> --confirm

<ref> is the lowercase derived label (e.g. alex-boring-angel-investor) OR a ULID prefix of at least 3 characters (e.g. 01j5hk7y or wld_01j5hk7y).

The squirrel drives the picker on error.code == "ambiguous_ref": render the picker block from the envelope, dispatch AskUserQuestion, re-run with the picked ULID.

The squirrel drives confirmation on error.code == "needs_confirmation": render the warning block, dispatch AskUserQuestion (Activate anyway, Cancel), re-run with --confirm.

See activate.md for full flow and resolution rules.

deactivate

Routes to deactivate.md. Restores the world-root pointer to the cached previous_world_root value, then clears active_world and previous_world_root in demo-state.json.

$ALIVE_PLUGIN_ROOT/bin/alive demo deactivate

Three result branches: ok (pointer flipped, restart Claude Code), no_demo_active (nothing to do), and no_previous_world (cold demo; user must create another or set the pointer manually).

See deactivate.md for the cold-demo case and atomicity contract.

delete <ref>

Routes to delete.md. Resolves <ref> (same rules as activate), refuses on the currently-active world, and (with --confirm) calls shutil.rmtree. Without --confirm, the CLI returns error.code == "needs_confirmation" carrying an irreversibility surface so the squirrel dispatches AskUserQuestion before the destructive call.

$ALIVE_PLUGIN_ROOT/bin/alive demo delete <ref>          # dry run; surfaces irreversibility block
$ALIVE_PLUGIN_ROOT/bin/alive demo delete <ref> --confirm  # actually delete

Active worlds raise error.code == "refused_active"; the user must /alive:demo deactivate first.

See delete.md for the irreversibility contract.

status

Routes to status.md. Prints a 5-7 line bordered block summarising the active demo world, the cached previous world-root, and the next-step hint.

$ALIVE_PLUGIN_ROOT/bin/alive demo status

The CLI runs state.load_state() which executes the world-root self-heal -- demo-state converges to whatever ~/.config/alive/world-root actually points at. The status envelope is the canonical "what does the system think is active?" surface.

See status.md for output shapes and the self-heal contract.

reset

This subcommand is router-owned, not a CLI handler. When the human runs /alive:demo reset:

1. Read ~/.config/alive/world-root via _world_root_io.read_world_root_file() to learn the live pointer (if any).
2. Atomically write a fresh demo-state.json matching state.default_state(). If the pointer names a directory previously promoted by the demo skill (recognizable by <world>/.alive/_demo-build-log.md), populate active_world from the build log. Otherwise leave it null.
3. Render this block:

╭─ 🐿️ demo state reset
│
│   demo-state.json rebuilt from world-root pointer.
│   Schema version: 0.1
│
│   active_world: <ulid|none>
╰─

Reset is the documented escape hatch when alive demo status raises schema_version_mismatch — the CLI's hint points here.
