dsh-digipet

Hatch a digital creature in your DeepSeek Harness — it feeds on your real work and evolves, raising-game style.

Write code and it becomes a dragon; read docs and it becomes a sage; keep shipping errors… and it becomes something that lives in ten million processes at once.

✨ DigiEgg evolved into Bitpop (Baby Ⅰ)
"A single bit that just raised its flag, not yet sure what it wants to become."

30 seconds to a pet

dsh plugin --profile web add github:swaylq/dsh-digipet
# restart dsh, then in any session:
/pet hatch

Then just work. Every completed turn +5 XP, each of your messages +2, every tool call +3, even every error +4. /pet to check on it, /pet evolve for the ceremony.

What it becomes depends on how you work

The life cycle follows classic V-pet canon in full: Egg → Baby Ⅰ → Baby Ⅱ → Child → Adult → Perfect → Ultimate. From Child onward, every evolution re-reads how you actually worked that stage to pick a lineage:

Lineage	What feeds it	Ultimate form
🐉 Dragon	writing files, running commands	Wardrake Sovereign
📜 Sage	reading code, searching docs	Codex Deva
🕊️ Angel	plain conversation	Seraph Prime
👾 Virus	errors and mishaps survived	Doomweaver — kill -9 only makes it split

3 shared baby forms + 4 lineages × 4 stages + 3 hidden forms = a 22-slot dex. Lineages are never locked in — a Dragon-line pet that spends a stage drowning in stack traces respecs into the Virus line. What it finally becomes is a mirror of how you actually worked.

As for the hidden forms, the dex offers only a rumor:

"Rumor: evolving on a stuffed belly ends badly."

Veterans know exactly what that means. Some mistakes can be redeemed by love; others pile up, layer upon inherited layer, into something ancestral (the last line of its art reads // don't touch.).

Commands

Command	Does
/pet	status card: art, XP, fullness, mood, four stats, lifetime counters
/pet hatch	lay the egg (one pet per DSH home; also triggers a ready egg's ceremony)
/pet evolve	the evolution ceremony
/pet name <name>	name it (≤16 chars)
/pet dex	the collection (unseen forms show as ？？？; hidden forms get only a rumor)
/pet story	its life journal
/pet about	mechanics and trust stance

Upgrading from 0.1.x: old saves (the sea-creature roster) migrate automatically and losslessly on next boot — stage, XP, stats, dex and journal all carry over, with historical forms mapped onto the new roster.

Why

The DSH ecosystem already has twenty-plus desktop pets (whale-girl, assorted whales, a revived Clippy, Live2D companions…). Nearly all of them are state mirrors: agent thinks, pet thinks; task done, pet cheers. The deepest one, whale-girl, has XP levels and titles — but its body never changes, and it lives only in the Web GUI.

None of them is a raising game: no hatching, no evolution stages, no "how you work decides what it becomes." dsh-digipet fills that square — a first-generation-V-pet growth loop hosted in your harness and fed by your actual work.

Overfeeding makes it drowsy (above 90% fullness, XP gain drops to 15%) — a thematically honest anti-grind valve. But veterans know: never press evolve on a stuffed belly.

How it works

The whole plugin is four event taps and one slash command:

Hook	Feeds
agent/turn-stopping	+5 XP per completed turn
agent/inbox/claimed	+2 XP per user message (feeds Bond)
tools/result	+3 XP per tool call, classified by tool name into Forge or Lore; failures feed Grit
agent/error	+4 XP per error (feeds Grit)

Thresholds: 30 / 120 / 500 / 1800 / 6000 / 16000 XP. Evolution takes the dominant stat of the window since the last evolution; the window then resets. The save lives at $DSH_HOME/digipet/state.json, written the same way the official JSON storage backend persists (temp file + fsync + atomic rename), throttled to one write per 1.5 s no matter how busy the agent gets.

DSH's core invariant is "model-visible means logged" — this plugin's answer is to show the model nothing at all. No registered tool (tool schemas are a per-request token tax), no agent.inject(), no session events. The pet exists only in command result cards and contributes zero bytes to every model request.

Trust stance

• Reads: only its own save file. It never reads your code or your conversation — the event taps use only what kind of thing happened; message and tool contents never touch the save.
• Writes: only $DSH_HOME/digipet/state.json.
• Network: none.
• Model surface: none. Zero token overhead; provider KV caches are untouched.
• Blast radius: every listener body is wrapped in try/catch and the command handler has its own error floor — a stumbling pet cannot veto, rewrite, or delay real work. All hooked events are notification-mode (emit/serial).

Known limitations

• One pet per DSH home; every profile, session, and subagent on the machine shares and feeds it (feature and limitation).
• Concurrent dsh processes race the save last-writer-wins — the same single-process stance as the official JSON backend.
• Tool classification is a name heuristic (write/edit/shell → Forge; read/grep/search → Lore); oddly named third-party tools count as neutral chow.
• The collapsed conversation row flattens the art to one line — click the card for the full monospace version (same interaction as DSH's tool rows).
• Thresholds and the diet are deliberately not configurable: changed numbers would leave the dex and old saves speaking different languages.

Verification record

Verified on dsh 0.1.0-rc.6 (macOS, web profile):

1. Installed via dsh plugin --profile web add <this repo>; the digipet layer appears in --dump-config;
2. dsh web boots clean;
3. In a real browser: /pet hatch renders the egg card (monospace, newlines preserved) → real events feed it to 30 XP → /pet evolve hatches Bitpop;
4. With no API key, plain messages still produce real events — the save matches the diet line by line;
5. A crafted 0.1.x save (glitch-line junior) was loaded across a restart: it migrated automatically onto the new roster with name, stats and journal intact;
6. 42 unit/integration tests (node --test) covering the pure logic core, a faked Cordis context, the stray-evolution arc, and migration.

Homage and boundaries

The roster's silhouettes honor first-generation V-pet raising canon — the skull-helmed dino arc, the cyborg retrofit, the winged guardians, the network virus, and that slug you get for raising it wrong. "Digimon" is a trademark of Bandai Namco; this project is unaffiliated, and all names, art and copy are original with no official assets.
