The Two Projects
Sister repo — minecraft-ai-god (Vanilla)
- Local path:
/root/bin/Sethpc-Minecraft - Gitea:
https://git.sethpc.xyz/Seth/minecraft-ai-god - Purpose: Vanilla Minecraft 1.21.x, no plugins or mods. All automation via log watching + RCON. Targets the mc1 server (port 25565) and shrink-world server (port 25566) on CT 644.
- Key services:
mc-godmode.service,mc-shrink-kit.service,mc-aigod.service - AI features:
praychat trigger → Ollama LLM → structured JSON → RCON execution; divine intervention timer; shrink-world kit/stats watcher
This repo — minecraft-ai-god-paper-fork (Paper Advanced Fork)
- Local path:
/root/bin/Sethpc-Minecraft-PaperFork - Gitea:
https://git.sethpc.xyz/Seth/minecraft-ai-god-paper-fork - Purpose: Dedicated Paper server on port 25567 with plugins (FastAsyncWorldEdit, LuckPerms). Extends the vanilla branch with build templates, expanded command set, sudo translator mode, and LangGraph-style session gateway.
- Key services:
mc-paper-ai.service,mc-aigod-paper.service,mc-langgraph-gateway.service - AI features: All vanilla features +
sudo build/make/createdeterministic templates,sudo lookup/wiki/search, LangGraph gateway sidecar (FastAPI on 127.0.0.1:8091), SQLite session persistence
Relationship Between the Two
This Paper fork is a direct evolution of the vanilla repo. They share:
- Same
pray/bible/sudotrigger style and chat patterns - Same two-call LLM split (message + commands JSON schema)
- Same RCON helper (raw socket, no library)
- Same command validation + syntax repair pipeline
- Same intervention timer design (Poisson process, presence guard)
This fork adds on top of the vanilla base:
- Plugin-enabled command families (
fill,setblock,clone) - Deterministic build templates before LLM translation
- LangGraph gateway with session memory and tool loop
server_typegating so paper commands don't leak to vanilla targets
Both can run simultaneously — they use separate ports, services, and config files.
Gitea Backup Workflow
Both repos push every committed change to Gitea. This is the standard workflow:
# From either local repo dir:
git add -A
git commit -m "<description of change>"
git push origin main
Both remotes are pre-configured with token auth:
- Vanilla:
https://Seth:<token>@git.sethpc.xyz/Seth/minecraft-ai-god.git - Paper fork:
https://Seth:<token>@git.sethpc.xyz/Seth/minecraft-ai-god-paper-fork.git
The Gitea instance lives at git.sethpc.xyz (CT 146, node-173, 192.168.0.125).
API key: see GITEA_API.md in this repo.
Convention: commit every meaningful change immediately. Commits are the changelog — no squashing, no batching unrelated changes.

AI Conversation Notes
This section captures decisions and context accumulated across conversations with the AI assistant (OpenCode/Claude). Update it as significant choices are made.
Architecture decisions
- No plugins on vanilla servers. All mc1 and shrink-world automation is pure log-tail + RCON. This keeps the vanilla experience intact and requires no server restarts for updates.
- Paper fork is separate, not a branch. Running both as separate services on separate ports was chosen over a single multi-mode script to keep failure domains isolated.
- LLM backend: Ollama at
192.168.0.179:11434for the vanilla service. This fork uses192.168.0.141:11434(steel141, local GPU) for better throughput on heavier models (gemma3:12b message model, qwen3-coder:30b command model). - Session gateway (this fork only): The LangGraph-style FastAPI sidecar adds multi-turn memory without requiring a full LangGraph install. Safety enforcement stays in
mc_aigod_paper.py, not the gateway. - Build templates: Deterministic templates are tried first for
sudo build/make/createrequests. LLM translation is the fallback. This reduces surprises for structure generation tasks. - Localized retrieval for sudo reasoning (2026-03-17):
langgraph_gateway.pynow supports a local knowledge corpus (/var/lib/mc-langgraph-gateway/knowledge) with index/search/read tools (local.search,local.read), optional startup bootstrap from Minecraft/Paper docs URLs, and automatic search->read retrieval hop in sudo tool mode before command generation. - Post-deploy behavior check (2026-03-17): retrieval is active (
tool_traceshowslocal.search+local.read) forsudo destroy my surroundings, but generated command remainedexecute as <player> run fill ~-5 ~-5 ~-5 ~5 ~5 ~5 airand produced no useful visible outcome in gameplay (empty/weak RCON feedback). Retrieval alone did not guarantee effective action selection. - Sudo execution hardening follow-up (2026-03-17): added command-shape normalization for sudo (
execute as <player> run ...->execute at <player> run ...), blocked execute-wrapper bypass in validator (unsafe inner tails likegameModeinsideexecute ... run), and added adaptive destructive fallback for faileddestroy/nukeintents (absolutefill ... airaround player + TNT summons / TNT kit fallback when position unavailable). - Sudo effectiveness feedback loop (2026-03-17): sudo now scores execution effectiveness from RCON results for all intents, reports translated commands + outcomes + ineffective flag back to gateway session memory (
mode=sudo_feedback,feedback_only=true), and gateway stores this feedback without running extra LLM/tool calls. - Lookup contextual memory fix (2026-03-17):
sudo lookup/search/wikinow resolves pronoun references (e.g., "that command", "do it again") against the player's most recent executed sudo command, includes that command in lookup context payloads, and passes sudo history into gateway lookup context to improve follow-up reasoning. - Gamemode/effect sudo fix (2026-03-17): Added
gamemodeto safe prefixes/whitelist and command palette, added syntax normalizer for malformed variants (gameMode s, short aliases, missing target) and execute-wrapped gamemode forms; confirmed valid RCON forms aregamemode <mode> <player>andeffect give <player> <effect> <duration> <amplifier> [hideParticles]. - AI-driven build/template flow (2026-03-17):
process_sudonow defaults to non-deterministic build planning (legacy deterministic builder templates disabled unlesssudo_deterministic_build_templates=true), supports AI-emittedtemplate ...meta-commands in sudo execution loop, and includes an AI template planner override for build/make/create prompts when initial translation does not emit template workflow steps. - Failed-execution retry pipeline upgrade (2026-03-17): sudo now runs a generic retry-repair pass on ineffective results before intent fallback. Added TNT-specific repair for malformed
summon tnt ... <count>outputs (expands into bounded multiple summon commands) and invulnerability-effect repair to valid protection effects. Addedtntto destructive-intent keywords so TNT requests can trigger destructive fallback when needed. - TNT retry syntax correction (2026-03-17): retry expansion for malformed TNT count commands initially emitted invalid relative coords with
~+1/~+2; corrected generator to use valid forms (~1,~2) so repaired TNT summons no longer fail withExpected double. - User preference (2026-03-17): prioritize context/prompt refinement and better model grounding over adding more deterministic hardcoded action paths.
- Context-first refinement pass (2026-03-17): added sudo failure memory (
sudo_failures) and anti-repeat context block (RECENT FAILED SUDO PATTERNS) into paper sudo translator input and gateway sudo context payload; prompt rules now explicitly forbid repeated failed shapes, old enchant NBT syntax, andsummon tnt ... <count>style outputs. - Prompt safety clarifications (2026-03-17): updated paper God/system prompts to enforce
effect give ...syntax,weather clear|rain|thunderonly, and avoid accidental high vertical teleports in benevolent outputs unless explicitly requested. - Sudo scope grounding (2026-03-17): paper sudo prompts now explicitly keep target scope narrow (
me/my-> requesting player), discouraging broad@aoutputs unless explicitly requested. - Unresolved post-update issues (2026-03-17): (1) AI template planner override can trigger on non-build sudo intents (example:
make me invisiblerouted intotemplate search/pick/build), and (2) sudo follow-up questions likedid that command ...?may not return an informational answer unless phrased with explicit lookup prefixes. - Resolved sudo routing issues (2026-03-17): tightened build-intent detection so template planner override only triggers for actual structure/template intents (no longer on generic
make me ...phrasing), and broadened sudo info-mode detection to treat natural question-style prompts (e.g.,did that command ...?) as lookup queries even without explicitlookup/search/wikiprefix. - Remaining issues after routing fix deploy (2026-03-17): (1) sudo still outputs old bow enchant NBT (
bow{Enchantments:[...]}) in some runs and fails with trailing-data parse error, and (2) God prayer outputs still occasionally include unnecessary teleport actions (tp ~ ~5 ~) that users report as unhelpful side effects. - Bugfix pass after in-game retest (2026-03-17): added command-repair normalizers for (a) old bow enchant NBT to 1.21 component syntax (
minecraft:bow[enchantments={...}]), and (b) legacy fire fill syntax (... fire 0 replace air->... minecraft:fire replace air), plus dynamic sudo command budget scaling for TNT prompts based on requested quantity (capped bysudo_tnt_max_commands, default 80). - Lookup and benevolent TP context refinements (2026-03-17): lookup mode now has local fallback answering for contextual gameplay questions (e.g., invisibility vs mobs) when retrieval returns no hits, and prompts/gateway guidance now explicitly discourage teleport use in helpful responses unless movement is explicitly requested.
- Post-retest fixes (2026-03-17): added execute-tail syntax repair so command fixers apply inside
execute ... run ...payloads (fixes old bow NBT + fill fire variants emitted under execute wrappers), and added TNT quantity expansion from prompt count for summon-heavy intents (bounded bysudo_tnt_max_commands, default 80) when model output under-produces summons. - Retest outcome (2026-03-17 late): bow repair now works in live runs (
give strongest bowsuccessfully converted old NBT tominecraft:bow[enchantments={...}]and delivered item). Remaining issues: fire-spread requests still often execute as no-op/invalid hybrid fill chains (execute ... run fill ... fire ...with mixed legacy args), and TNT intent can still collapse into single-command failure then destructive fallback (largefill ... air+ few TNT) instead of honoring requested count semantics. - Late-night retest results (2026-03-18): strongest-bow path is confirmed fixed; lookup follow-up (
did that command do what I asked?) still intermittently returns no result; fire-spread prompt still no-ops/invalid despite syntax repair; TNT quantity prompts (spawn 80/20 tnt) still execute a single summon in some runs, indicating quantity expansion is not consistently applied before execution. - Follow-up fixes after late-night retest (2026-03-18): added per-player
last_sudo_feedbackmemory and deterministic lookup fallback answer fordid that command do what I asked?; expanded execute-tail repair coverage and fire fill metadata repair (... fire 0 replace <block>); disabled destructive air-fill fallback for TNT intents; added fire-intent fallback retry and robust TNT expansion by parsing summon tail from nested execute wrappers. - Project governance for bug intake (2026-03-17):
bug_logreports from all players are useful advisory input, but direction/prioritization authority remains with project owner (slingshooter08); non-owner reports should be weighted accordingly. - God voice update (2026-03-17): Increased default God persona emphasis on irony, dark humor, and sarcastic one-liners in both command and message system prompts (vanilla + Paper variants) while keeping command strictness unchanged.
- Bug-log triage (2026-03-17):
bug_logentry confirmed an unintended-feeling movement reward in prayer flow (execute as slingshooter08 run tp slingshooter08 ~ ~10 ~) during a build-oriented prayer; prioritize pray-path teleport safety guards and intent alignment. - Bug follow-up (2026-03-17): second
bug_logentry reported God feeling "too nice" after greedy follow-up prayer; prompt context updated to bias repeated greedy demands toward corrective responses (rebuke/debuff/symbolic punishment) instead of extra rewards. - Teleport safety guard (2026-03-17): added execution-time TP safety wrapper in prayer/intervention path (
execute_response) to auto-applyslow_falling+resistancebefore risky upward teleports, reducing accidental player death from unintended high drops. - Bug-log signal upgrade (2026-03-17):
bug_lognow writes filtered raw server log lines (RCON thread noise removed) and includes recent AI action lines from/var/log/mc_aigod_paper.logfor better root-cause visibility. - Unaddressed bug triage (2026-03-17): third
bug_logentry ("output not in correct format") maps to prayer execution using invalid commandweather storm(RCON: Incorrect argument). Current validator allowsweatherprefix but lacks argument normalization (storm->rain) and no retry/repair pass for pray-path commands. - Weather normalization fix (2026-03-17): added explicit prompt/context rule and code normalizer mapping
weather storm|rainstorm|thunderstorm->weather thunderbefore validation/execution (paper + vanilla), then redeployed both services. - New bug cluster observed (2026-03-17): additional paper
bug_logentries report failed command outcomes around selector-based targets and legacy enchant syntax in sudo (minecraft:bow{Enchantments:...}), indicating retry/repair still needed for 1.21 enchantment conversion and selector reliability feedback.
Infrastructure decisions
- mc1 autoStart: Set to
truein MCSManager instance config (/opt/mcsmanager/daemon/data/InstanceConfig/d39f55861cb34204a92a18a9e1c78ca6.json) so the server starts on CT 644 boot.mc-godmode.serviceusestail -Fand handles the log appearing late gracefully. - mc-godmode.service startup: Already enabled (
systemctl is-enabled= enabled),WantedBy=multi-user.target,After=mcsm-daemon.service. The service was not failing — the MC server itself wasn't auto-starting (fixed by enabling autoStart in MCSManager config). - Paper server location:
/opt/paper-ai-25567/on CT 644. Separate from MCSManager-managed instances.
