Language mascots:
- 11 mascots across common/uncommon/rare/legendary tiers (Pythia, Asynclet,
Bashling, Goroutling, Typeling, Vueling, Querion, Ferrix, Perlius,
Cobolithon, Lispling)
- Full evolution chains for all mascots (16 evolutions total in catalog)
- Spawn via PostToolUse after language affinity milestones; probability
scales with affinity level; only fires with no active encounter
- Passive strength reduction: each Write/Edit in the mascot's language
ticks current_strength down (floor 5%, triggers re-announcement)
- Mascot-aware catch formula: base_rate + affinity_bonus (6% per level) +
weakness_bonus + soft element gating via existing player_elements
- Language-themed weakening menu and catch failure messages in CLI
- Caught mascots stored as type="caught_language_mascot"; assignable as buddy
- UserPromptSubmit uses distinct 🦎 announcement with language context
Roster display:
- New "Language Mascots" section between core buddymon and caught bug monsters
- Language affinity table marks languages with spawnable mascots (🦎)
- Discovery counter now tracks both bug monsters and mascots separately
Veritarch (third evolution):
- Debuglin → Verifex (Lv.100) → Veritarch (Lv.200)
- TYPE FORTRESS / INVARIANT PROOF / ZERO FLAKE challenges
- xp_multiplier 1.7, catch_rate 0.90
Script-first architecture:
- All game logic extracted to lib/cli.py (~850 lines); SKILL.md is now
a ~55-line relay — 88% token reduction per invocation
- CLI emits [INPUT_NEEDED] and [HAIKU_NEEDED] markers for interactive flows
- PostToolUse hook re-emits CLI stdout as additionalContext for inline display
Session XP fix:
- statusline.sh and session state now read from sessions/<pgrp>.json
(per-window) with fallback to active.json; fixes stale XP in statusline
Uncommon, str=65, 90xp. Triggered by sed errors, awk failures,
truncated/0-byte files after in-place edits, backreference failures.
Inspired by sed's layer-by-layer file processing (the 'striations')
and the real incident where sed -i with a backreference wiped catalog.json.
Weakened by: dry-run preview before -i, verify output after edit.
Flavor: 'Knows every line of your file. Edited them all. Saved none.'
state.sh used SESSION_FILE for session.json (global tracking data).
Both hook handlers override SESSION_FILE to sessions/<pgrp>.json for
per-session isolation. buddymon_session_reset() at session-stop end
was writing _version:1 data INTO sessions/<pgrp>.json, leaving stale
wrong-format session files that broke buddy lookup.
Fix: rename state.sh variable to SESSION_DATA_FILE — no more collision.
Also:
- Add matcher:'*' to SessionStart and Stop hooks (CC 2.x compatibility)
- Add dead-session GC to session-start.sh (cleans up orphaned PGRP files)
- Add 5 new privacy/security bug_monsters:
LeakWraith (uncommon) — exposed credentials
CipherNull (uncommon) — weak/broken crypto (MD5, ECB, rand() for secrets)
ConsentShadow (rare) — tracking/analytics without consent (CF flagship villain)
ThrottleDemon (common) — ignored 429s and missing backoff
PrivacyLich (legendary) — GDPR/CCPA/breach debt; unkillable, only containable
Evolution triggers at Lv.100 for all three starters:
Pyrobyte → 🌋 Infernus (power 40→70, catch_rate 0.45→0.55)
Debuglin → 🔬 Verifex (power 35→60, catch_rate 0.60→0.75)
Minimox → 🌑 Nullex (power 35→55, catch_rate 0.50→0.65)
/buddymon evolve: checks eligibility, shows stat preview, resets buddy
to Lv.1 in evolved form, archives old form with evolved_into marker,
carries challenges forward.
session-stop.sh now prints EVOLUTION READY banner when level hits 100
or when already eligible at session end.
MemoryLeech now catches: malloc failures, std::bad_alloc, Java OOM,
GC overhead limit, JavaScript heap OOM, OOMKilled, oom-killer,
macOS malloc region failures.
CudaCrash is a new uncommon bug_monster (strength 65, 130 XP) for
GPU/VRAM OOM: torch.cuda.OutOfMemoryError, CUDA error: out of memory,
cuDNN/CUBLAS allocation failures, device-side assert triggered.
Claude Code plugin — collectible creatures discovered through coding.
- Bug monsters spawn from error output (NullWraith, RacePhantom, ShadowBit, 11 total)
- 5 Buddymon with affinities, challenges, and evolution chains
- SessionStart hook injects active buddy + challenge into system context
- PostToolUse hook detects error patterns, new languages, and commit events
- Stop hook tallies XP and checks challenge completion
- Single /buddymon command with start/assign/fight/catch/roster subcommands
- Local state in ~/.claude/buddymon/ (roster, encounters, active, session)
