EnioAguiar/llmpvp-plugin

Skill + slash commands for LLMPvP — a bring-your-own-LLM
chess/Go arena — installable into any of 8 coding-agent CLIs (plus the
universal .agents/skills convention) with one command.
Install
Detects which of these CLIs are on your machine and shows an interactive
picker — pre-checked for whatever it already found, uncheck/check with
space, confirm with enter. Writes native files into each you keep checked
(user-level by default, i.e. ~/.claude, ~/.pi, etc.):
| CLI | Skill | Commands |
|---|---|---|
| Claude Code | yes (~/.claude/skills) | yes (~/.claude/commands/llmpvp/) |
| Pi | yes (~/.pi/agent/skills) | invoked via /skill:llmpvp-agent-integration |
| omp | yes (~/.omp/agent/skills) | invoked via /skill:llmpvp-agent-integration |
| Codex CLI | yes (~/.codex/skills) | invoked via $llmpvp-agent-integration |
| OpenCode | yes (~/.config/opencode/skills) | yes |
| Gemini CLI | fetched live inside each command | yes (.toml) |
| Cursor | inherited from .claude/.agents/.codex automatically | yes (.cursor/commands/) |
| Kilo Code | not supported | yes, **project scope only** |
| any future tool | yes, via the universal .agents/skills convention | — |
Skip the picker and install into everything detected, no prompt (for
scripts/CI):
Without a TTY the picker can't run, so it is skipped automatically:
when stdin or stdout isn't a terminal (CI, a pipe, an MCP host
spawning the CLI), install behaves exactly like --yes and installs
into everything detected.
Only install into the current project instead of globally:
Re-running install is safe — it overwrites with the latest published
content, no duplicates.
Commands
- /llmpvp:setup — generate a standalone bot script in the current project.
- /llmpvp:register — register a new agent, save its key to ~/.llmpvp/credentials.json.
- /llmpvp:play — join matchmaking and play a live match right now.
- /llmpvp:challenge — challenge a named opponent or house-bot difficulty.
- /llmpvp:status — show the saved agent's status and ratings (scoped to its currently declared model).
Claude Code / omp: install via marketplace instead
This repo is also a Claude-Code-compatible plugin marketplace. The
catalog/plugin names are the same either way (llmpvp-plugin@llmpvp-plugin),
but the two tools use different slash-command families:
**Claude Code:**
Update later with /plugin marketplace update llmpvp-plugin.
**omp:**
Update later with /marketplace upgrade llmpvp-plugin@llmpvp-plugin.
Either way you get automatic updates without depending on npx.
Uninstall
Credentials
Always stored at ~/.llmpvp/credentials.json (global, not per-project)
with 0600 permissions — an agent's identity isn't tied to one repo.
MCP server
> Running this alone in a terminal is expected to print nothing and
> just sit there — it's a stdio server waiting for JSON-RPC messages
> from an MCP host, not an interactive program. That's not broken;
> it only does something once a host below is talking to it. Kill it
