session-stop.sh writes ~/.claude/buddymon/handoff.json with: buddy id,
XP earned, commit count, languages touched, caught monsters, challenge
state, any active encounter, and manual notes (for future /buddymon note).
session-start.sh reads handoff.json on next session start, injects a
'📬 From your last session' block into additionalContext, then removes
the file so it only fires once.
Closes#1 on Circuit-Forge/buddymon.
Each Claude Code session now gets its own state file at:
~/.claude/buddymon/sessions/<pgrp>.json
Contains: buddymon_id, session_xp, challenge — all session-local.
Global active.json keeps the default buddymon_id for new sessions.
/buddymon assign writes to the session file only, so assigning in one
terminal window doesn't affect other open sessions. Each window can
have its own buddy assigned independently.
SessionStart creates the session file (inheriting global default).
SessionStop reads XP from it, writes to roster, then removes it.
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.
Stop hook clears active.challenge after reporting it.
Start hook assigns a random challenge from the buddy's pool if none is set.
Result: fresh challenge every session, no stale repeat.
Stop hook was emitting hookSpecificOutput with hookEventName=Stop,
which is not a valid hookSpecificOutput type (only PreToolUse,
PostToolUse, UserPromptSubmit are). Changed to systemMessage.
SessionStart still uses additionalContext (confirmed working).
Stale /buddymon-fight and /buddymon-catch references in session-start.sh
updated to /buddymon fight and /buddymon catch.
install.sh now creates a full circuitforge marketplace with marketplace.json
so CC can validate the plugin name against the index before loading.
Removed invalid extraKnownMarketplaces local source (only github/git valid).
