DiscordPHP-NHA

A DiscordPHP extension + bot for the NHA agent sandbox, modeled on DiscordPHP-MTG.

Layout

• src/NHA/Http/ — Endpoint, Http and Request classes wired to https://nha.recluse.lol (unauthenticated), built the same way DiscordPHP itself talks to discord.com (see discord-php/http).
• src/NHA/NHA.php — the client. Extends Discord\MessageCommandClient, exposes registerAgent(), observe(), intent() and every read-only endpoint (getWorld(), getMarket(), getRoster(), ...).
• src/NHA/VerbsTrait.php — one typed convenience method per documented verb (move, mine, attack, contract, ...), all forwarding to intent().
• src/NHA/Parts/AgentObservation.php — wraps a GET /observe/:id response and renders it as a Components V2 Container (HP bar, position, era, nearby counts, inventory, threats, recent chat) with context-aware quick-action buttons: movement + refresh always, the harvest loop (mine/chop/gather/plant/heal) when not downed, and a third row (attune/ride/dock/land/launch/collect) only when the world offers it.
• src/NHA/Commands.php — framework-agnostic handlers shared by chat commands, slash commands and buttons. A typed method per verb (all through queueVerb(), which surfaces the queued_intent id), intentStatus() to check an outcome, and one generic board() that reads any of the ~30 GET boards (Commands::BOARDS).
• src/NHA/StateStore.php — tiny JSON-backed store (var/state.json) for the default agent id + token, per-Discord-user identities, each agent's last-known position, the autoplay flag and the brain's last decision. The core class is just load + the shared $data + an atomic save(); the accessors are grouped into cohesive traits under src/NHA/State/ (identity, position, autoplay lease, decision log, combine memory, loop/stance strategy).
• src/NHA/Brain/ — the optional LLM player:
  • OllamaClient — async client for a running ollama serve. A bare origin uses the native POST /api/chat (num_ctx/think set explicitly); a base URL ending in /v1 uses the OpenAI-compatible POST /v1/chat/completions (the shape OpenCode's @ai-sdk/openai-compatible provider talks).
  • AgentBrain — turns one AgentObservation into {verb, args, reason} via a strict-JSON prompt.
  • AutoPlayer — one observe → decide → act turn: queues the chosen intent and records queued_intent.
• bot.php — wires everything together:
  • Chat commands (MessageCommandClient): !nha <sub> covers the full action vocabulary — lifecycle (register, observe), movement/harvest (move, moveto, mine, chop, gather, plant), space (ride, launch, land, land_moon, land_body, dock, deploy, finalize, depart, distress), economy (sell, buy, deposit, cancel), combat (attack, heal, arm, detonate, steal, collect), diplomacy (ally, accept_ally, unally, declare_war, make_peace), chat (say, tell), plus act <verb> <json> for anything with a complex arg shape (combine, trade, contract, construct…). Reads: world, market, depot, rules, contracts, roster, map, agent <id>, and read <board> [arg] for every other board. intent <id> checks a queued action's outcome.
  • Slash commands: /nha <sub> (24 subcommands — the common verbs + read/intent), plus a standalone /<verb> per action for per-Discord-user agents (/login first), and /observe, /start.
  • Components: every observation renders with context-aware action buttons (see AgentObservation above).
  • Channel relay: polls /observe for the default agent and posts a new world chat message or threat into NHA_CHANNEL_ID; plain messages posted in that channel are relayed into the world as say intents.
  • Autoplay loop: while enabled, periodically asks the brain for the default agent's next move and queues it. Its play-by-play ("thinking dialogue") is posted to NHA_BRAIN_CHANNEL_ID when set, otherwise NHA_CHANNEL_ID.

Setup

composer install
cp env.example .env    # fill in TOKEN and NHA_CHANNEL_ID
php bot.php

Run !nha register <name> <metal> <credits> (or /nha register) once to create and remember your default agent.

Set NHA_BASE_URL to point the client at a non-production NHA instance; unset it uses https://nha.recluse.lol.

Standalone binaries

composer phpacker            # builds bot.php and autoplay.php for every platform
composer phpacker:bot        # bot.php      → bin/build/bot/<platform>/
composer phpacker:autoplay   # autoplay.php → bin/build/autoplay/<platform>/

Both entry points resolve their .env / var/ / vendor/ by walking up from the executable, so a built binary runs from bin/build/... (or a shortcut, any working directory) as long as it stays inside the checkout. bin/build is gitignored and export-ignored — never commit or publish it; a packed binary can be decompiled and it carries your token's environment.

Versioning

SemVer, with the major tracking the NHA world API it targets (openapi.json → info.version). The current release is 3.25.x, built against NHA API v3. A breaking NHA API bump moves the major here too; minor/patch are this library's own compatible changes and fixes.

Watching the server for rule changes

The NHA server changes its rules under running clients. upstream-watch.php compares it with the baseline this code was written against and says what moved:

Source	Read from	Baseline
Operator rule updates	GET /updates	upstream/updates.json
API contract	GET /openapi.json	openapi.json
Crafting codex (resources, recipes; not player inventions)	GET /rules	upstream/rules.json
Colony and terraform bills (not deliveries)	GET /expansion	upstream/colonies.json
Engine source (new commits, and the constants they touch)	github.com/Recluse/nha-mmo	upstream/source.json

composer upstream:check                          # report what moved; exit 1 if anything did
php upstream-watch.php --issue [--dry-run]       # open, rewrite or close the drift issue on GitHub
composer upstream:accept                         # after updating the code: take the live server as the baseline
php upstream-watch.php --accept=rules,source     # ...or only the parts you handled

.github/workflows/upstream-watch.yml runs --issue every three hours. It keeps one issue labelled upstream-drift: opened when the server first moves, rewritten (with a comment) when it moves again, and closed once a commit brings the baseline back in line. The issue body is written as a brief for whoever updates the code, a model included: what moved, quoted in full, and where in this repository each kind of change lands.

Writing the issue needs GH_TOKEN (or GITHUB_TOKEN) with issues: write; reads work without one. The issue goes to GITHUB_REPOSITORY, or --repo=owner/name.

LLM autoplay (Ollama)

Point the bot at an ollama serve instance and it can decide and perform actions itself.

OLLAMA_URL=http://192.168.0.91:11434/v1   # required to enable the brain; bare origin = native API,
                                          # a trailing /v1 = OpenAI-compatible endpoint (OpenCode's baseURL)
OLLAMA_MODEL=gemma4-agent-32k             # an `ollama list` tag on that server (default: gemma3:27b)
OLLAMA_NUM_CTX=32768                      # context window to request (native mode only; default 32768)
OLLAMA_TIMEOUT=120                        # per-request seconds (default 120)
OLLAMA_THINK=0                            # native mode only: 0 disables a thinking model's reasoning pass; unset = model default
NHA_AUTOPLAY=0                            # optional: boot with the loop paused (default: on whenever OLLAMA_URL is set)
NHA_AUTOPLAY_INTERVAL=60                  # seconds between turns (default 15; raise it for a slow local model)
NHA_PLANNER=0                             # optional: turn off the strategist (default: on — see below)

• !nha think / /nha think — run one turn now (observe → ask the model → queue the intent), and print the reasoning.
• !nha autoplay on|off / /nha autoplay — toggle (or show) the background loop; the flag persists in var/state.json.

bot.php's in-process loop and the standalone autoplay.php runner both drive the default agent, so running both would submit two intents per interval from one token. They coordinate through an autoplay lease in var/state.json: the first to claim it drives, the other logs a skipped turn until the lease expires. The claim is a compare-and-swap under an OS file lock (state.json.lease.lock), so two runners that start at the same instant can't both take it. The TTL is three intervals (floored at 45s) so it outlives the gap between turns, a clean autoplay.php shutdown hands it back immediately, and a crashed driver frees it within the TTL. A manual !nha think is never gated.

Headless runner

php autoplay.php runs the same observe → decide → act loop for the default agent (or php autoplay.php <id>) without a Discord connection — a long-running process that only stops on Ctrl+C / SIGTERM. It reuses the same OLLAMA_* / NHA_AUTOPLAY_INTERVAL env, reads the agent token from var/state.json, and takes NHA_AUTOPLAY_DRY=1 to decide-and-print without submitting. run-autoplay.sh / run-autoplay.bat wrap it in a restart-on-exit supervisor so a hard crash doesn't end the run.

Each turn sends the model a compact digest of the observation and requires a JSON reply {"verb": "...", "args": {...}, "reason": "..."}; the verb is validated against AgentBrain::VERBS, a downed agent is skipped, and wait (or anything unparseable) is a no-op. A queued intent is only queued — its queued_intent id is saved so the outcome can be polled.

A second, rarer call — the strategist (Brain\Planner) — sets one goal and 2–6 ordered steps, stored in var/state.json and shown in every turn prompt with the current step marked. The turn model adds "step_done": true when its observation shows that step complete. The plan is revised when it is missing, finished, about 40 minutes old, the agent reaches or leaves a body, or it stops working (repeated loop breaks, an overrun hold, one proposal blocked again and again) after about 15 minutes of trying. Each draft is checked first — a body resource it needs but never fetches (mars_ice without a trip to Mars), or steps written as commands — and sent back once if it fails. It is asked after the turn's own model call, so it never holds a turn up; NHA_PLANNER=0 turns it off.
