pi-ext-fan

pi-coding-agent extension: @agent interception + family-bucket companion installer.

Features

1. @agent syntax interception + autocomplete

Type @<agent-name> <task> in the input box to dispatch to a sub-agent:

• @workhorse "write the tests" → transforms into /run workhorse "write the tests"
• Autocomplete for agent names on @ (from built-in + ~/.pi/agent/agents + ~/.agents)
• Toggle with /ext on / /ext off (or /ext at-agent [on|off])

2. /ext command surface

Bare /ext (or /ext help) prints the subcommand summary:

/ext commands:
  help                                  show this help
  status | list | ls                    at-agent state + companion install status
  install-all                           install every companion in dependency order
  setup [name ...]                      interactive picker (or run named companions)
  uninstall [name ...]                  picker of installed pi-type, or `pi remove` named
                                        (copy/check types are not uninstallable)
  on | off                              enable / disable @agent interception
  at-agent [on|off]                     toggle (default) or set @agent interception

• /ext status (alias: /ext list, /ext ls) — at-agent state + companion install status, grouped by aiwayds / rpiv / ecosystem with per-line ✅/❌. The three names share a single handler, so output is identical.
• /ext on / /ext off — enable / disable @agent interception directly.
• /ext at-agent [on|off] — alias-set (at-agent / at_agent / atagent) that accepts an optional on / off argument, defaulting to a toggle.
• Unknown subcommands print the help text plus a one-line error pointing at /ext help — no silent no-op, no crash.

3. Family-bucket installer (/ext install-all / /ext setup)

The family bucket covers 18 companions in 3 groups. Each entry is one of three action types:

• pi — installed via pi install <source> (tracked to latest)
• copy — agent .md files synced into ~/.pi/agent/agents (copied only when the target file does not already exist, so local customizations like a hand-tuned oldfox.md are never overwritten)
• check — probes a CLI (command -v …); when missing it only prints an install hint, it never runs an installer

Key	Label	Type	Detail
lean-ctx	lean-ctx (pi extension)	pi	npm:pi-lean-ctx
lean-ctx-cli	lean-ctx CLI	check	probes command -v lean-ctx; hint: cargo install lean-ctx (or brew tap yvgude/lean-ctx && brew install lean-ctx)

pi-subagents	Subagents	pi	npm:@tintinweb/pi-subagents

Both /ext install-all and /ext setup share the same sequential runner. Items execute in strict dependency order — all pi installs first, then the copy sync (depends on fun-agent's agents being on disk), then the check probes — and within each phase the list order is preserved (never concurrent).

/ext uninstall and /ext uninstall <name>... share the same runner with the action="uninstall" flag. The dependency order is preserved (pi-type attempts come first), but the per-phase handling diverges:

• pi-type — pi remove <source> is invoked only for currently installed items; not-installed items are skipped.
• copy-type — skipped (not uninstallable). The synced agent files in ~/.pi/agent/agents/ may carry user customizations, so deleting them would be destructive. This version never removes them.
• check-type — skipped (not uninstallable). These entries describe external CLIs (lean-ctx, etc.) with no installed artefact on disk; the user is expected to uninstall the CLI through its own package manager.

Both operations share a single in-flight latch: an /ext install-all (or /ext setup) started while /ext uninstall is running (and vice versa) is rejected with a notify naming whichever action is currently in flight.

Per-item progress is rendered in an editor widget above the input, updated in place after each item. The widget shows a 1-line counter header (e.g. Installing 12/18 · installed=5 skipped=3 failed=1 or Uninstalling 3/8 · removed=2 skipped=1 failed=0) followed by the last 9 lines — the most recent results plus the current in-progress row. Older results scroll off the top as the run continues; the full list and a final Done. summary arrive in the notify once the run completes.

Line shapes (install):

• [3/18] Sidebar Panel … — starting
• [3/18] Sidebar Panel ✅ installed (2.1s) — pi install succeeded
• [3/18] Sidebar Panel ⏭ skipped (already installed) — pi already present
• [3/18] Agents (auto-sync) ⏭ skipped (target exists) — copy target already present
• [3/18] lean-ctx CLI ℹ hint: cargo install lean-ctx — check probe missed
• [3/18] Sidebar Panel ❌ failed: <error> — non-zero exit / thrown exception

Line shapes (uninstall):

• [3/8] Sidebar Panel … — starting
• [3/8] Sidebar Panel ✅ removed (1.8s) — pi remove succeeded
• [3/8] Sidebar Panel ⏭ skipped (not installed) — pi not currently installed
• [3/8] Agents (auto-sync) ⏭ skipped (not uninstallable: copy targets may be user-edited) — copy type refused
• [3/8] lean-ctx CLI ⏭ skipped (not uninstallable: check entries are CLI probes only) — check type refused
• [3/8] Sidebar Panel ❌ failed: <error> — non-zero exit / thrown exception

A single failure never aborts the run; subsequent items continue. When the last item finishes, the widget clears and a single notify summarises Done. installed=X skipped=Y failed=Z (total N) (install) or Done. removed=X skipped=Y failed=Z (total N) (uninstall), followed by the full result list and an action-specific reload reminder — install runs Reload pi (/reload) to activate new extensions, uninstall runs run /reload to apply.

• /ext install-all — one-shot setup: installs every missing pi-type companion, re-syncs agents (idempotent, skips existing files), probes the CLI checks. No picker, no prompts.
• /ext all — deprecated alias for /ext install-all; prints a warning notify ('all' is deprecated — use '/ext install-all') and then runs the same one-shot path. Kept so existing muscle memory still works.
• /ext setup — interactive checkbox picker (all selected by default, grouped): space toggles a row, a selects all/none, enter runs the checked ones, esc cancels.
• /ext setup <name> [<name>...] — run named companions directly (still uses the sequential runner and the same per-item progress widget).
• /ext uninstall — interactive picker of currently installed pi-type companions only (copy/check are filtered out — they're not uninstallable). Same space/a/enter/esc keys as /ext setup; same progress widget and summary format with removed= instead of installed=.
• /ext uninstall <name> [<name>...] — pi remove named items directly. copy and check items are accepted at the dispatch layer (so muscle memory like /ext uninstall agents doesn't error) but skipped in the runner with a clear reason; unknown names are rejected up front.

4. /think — cycle/set thinking level

/think cycles off → minimal → low → medium → high → xhigh → max; /think high sets a specific level.

5. Skill shortcuts

• /init → forwards to /skill:init (root AGENTS.md)
• /init-deep → forwards to /skill:init-deep (.architect shadow tree)

Install (fresh environment, three steps)

pi install npm:@aiwayds/pi-ext-fan

Then, inside the pi session:

/ext install-all    ← full setup: installs every missing companion, syncs agents, probes CLIs
/reload             ← activates the newly installed extensions

That's it — /ext install-all skips anything already installed, re-syncs agents without touching existing files, and only reports a hint for missing CLIs. It's idempotent and safe to re-run anytime a companion is missing or a new agent file should be picked up.

Prefer a manual pick? Use /ext setup (interactive checkbox list) or /ext setup <name> for a single package. Check what's present with /ext status (or its list / ls aliases).
