@wierdbytes/pi-peon

CESP / OpenPeon sound-pack player for the pi coding agent.

"Work, work."

Drop a sound pack into ~/.openpeon/packs/<name>/ (or install one from the community registry - 300+ packs: peons, GLaDOS, Stronghold lords, StarCraft battlecruisers, ...) and pi will play a clip on every notable lifecycle event.

Install

pi install @wierdbytes/pi-peon

The default config points at the peon pack (Warcraft III Orc Peon). If it isn't on disk yet, the extension auto-downloads it from the community registry on session_start. The pack ends up at ~/.openpeon/packs/peon/ and the very first session.start clip plays as soon as the install finishes — no restart needed.

What you hear

| pi event | CESP category | | ----------------------------------------- | ------------------- | | session_start (startup / new) | session.start | | agent_start | task.acknowledge | | agent_end (turn used tools) | task.complete | | agent_end (no tools, just chat) | input.required | | tool_result with isError === true | task.error | | after_provider_response with status === 429 | resource.limit | | session_shutdown (reason "quit") | session.end | | user sending ≥ 3 messages in 5 s | user.spam |

Every category can be toggled individually from the settings modal - the on-disk pack decides whether that category has actual sounds, and missing categories are silently skipped (per spec).

Commands

/peon                  open settings modal (active pack, volume, mute,
                       per-event toggles, registry browser, sound preview)
/peon status           print active pack + player + config path
/peon mute             silence every category until /peon unmute
/peon unmute
/peon test [category]  play a random sound from the named category
                       (defaults to session.start). Bypasses debounce.
/peon reset            restore default config

CLI flag --no-peon disables playback for one pi session without touching the config.

Settings modal

Everything you can configure interactively lives behind /peon:

• Packs… — one unified picker for everything pack-related. Opens a sectioned list with three groups:

  • Active — the pack currently bound to events.
  • Available — installed packs at ~/.openpeon/packs/.
  • Registry — everything else from https://peonping.github.io/registry/index.json.

  Keys inside the picker:

  • ↑/↓ — navigate (skips section headers).
  • Enter — drill into the highlighted pack's sound files.
  • Tab — set the highlighted pack as active. Downloads + installs automatically when the pack lives only in the registry.
  • Esc — back to the main settings.
  • Type to substring-filter across pack id, display name, description, tags, language, and trust tier (case-insensitive).

  Inside the files drill-in:

  • ↑/↓ — navigate the sound list (no filter row — a single pack rarely has more than ~30 clips).
  • Enter — play the sound. Uses the local copy if the pack is installed; otherwise downloads just that one clip to $TMPDIR/peon-previews/ and plays from there — no full-pack install needed for auditioning.
  • Tab — set this sound's pack as the active pack (same install- if-needed logic).
  • Esc — back to the packs picker.

  Left/Right arrows are filter-cursor movement only — they don't drive navigation between submenus.

• Master volume — 0–100. Scaled to each backend's native range (afplay's -v 0.0–1.0, paplay's 0–65 536, ffplay's -volume 0–100).

• Muted — global kill switch.

• Per-event toggles — one boolean per CESP category. The settings description tells you whether the active pack actually has sounds for that category.

Audio backends

Detected once per session via which / where:

| Platform | Order tried | | -------- | ---------------------------------------------------- | | macOS | afplay | | Linux | pw-play, paplay, ffplay, mpv, play, aplay | | Windows | powershell.exe (System.Windows.Media.MediaPlayer) |

aplay has no volume control; the master-volume setting is ignored when it's the only backend.

Override the pack root with PEON_PACKS_DIR=/some/other/dir. Override the state dir with the standard PI_AGENT_DIR.

Picker behaviour

• No-repeat - when a category has > 1 sound, the picker never picks the same one twice in a row.
• Debounce - events firing within 500 ms of the previous play of the same category are suppressed.
• User-spam cooldown - user.spam re-fires at most once per 10 s.

Spec reference

Built against CESP 1.0. Manifest format, category-alias fallback, and tarball-from-GitHub install flow all follow the spec verbatim - packs that work in any other CESP-aware tool work here, and vice versa.
