What it does

Rpg is an agent skill from gamedev-skills/awesome-gamedev-agent-skills. Build an RPG: stats and leveling, inventory and equipment, quests, branching dialogue, save/load, and combat. Use for an RPG/JRPG, or designing stat, inventory, quest, or combat systems.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/stats-combat-quests.md`).

It sits in Game Development. The repository describes itself as: 74 game-dev skills for AI coding agents — Godot, Unity, Unreal, Phaser, PixiJS, three.js, Bevy, pygame, LÖVE, Roblox. Portable SKILL.md Agent Skills (the format Anthropic… The licence is Apache-2.0.

When your agent uses it

  • Game Development work in your project

Example prompts

  • “/rpg”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Derived stats from base attributes (recompute, never store as truth)
  2. XP curve + level-up
  3. Quest objective update driven by game events

What it can do on your machine

Read from SKILL.md and the folder at commit 0a70cfc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are python).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Rpg loads about 1.6k tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 48 tokens; SKILL.md has 571 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~48
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Build an RPG: stats and leveling, inventory and equipment, quests, branching dialogue, save/load, and combat. Use for an RPG/JRPG, or designing stat, inventory, quest, or combat systems.

RPG

A playbook for role-playing games — stats and progression, inventory/equipment, quests, dialogue, and combat. This is a compositional skill: it ties data-driven content, dialogue, and saving together. It does not re-teach those primitives; it defines the systems that make growth and choice feel meaningful, and points to the skills that implement each.

When to use

  • Use when building an RPG/JRPG/action-RPG: the player has stats that grow, an inventory, quests, dialogue, and persistent progress.
  • Use when designing a leveling curve, a damage formula, an inventory/equipment model, or a quest state machine.

When not to use: permadeath dungeon runs with no persistent character → roguelike. Pure conversation/branching story → visual-novel. Open-world needs/crafting/base-building → survival-crafting. For the dialogue engine itself, use dialogue-systems.

Core loop

Explore → encounter (fight / talk / solve) → earn rewards (XP, loot, story) → grow (level up, gear up, unlock) → take on harder content. The fantasy is getting stronger and shaping who your character is; every system should feed that growth-and-choice loop.

Must-have systems

  1. Stats + leveling — base attributes, derived combat stats, XP curve, level-up gains.
  2. Inventory + equipment — data-defined items, stacking, slots, stat modifiers.
  3. Combat — turn-based or action; damage formula, status effects, win/loss.
  4. Quests — objectives, state machine (available→active→complete→turned-in), rewards.
  5. Dialogue — branching lines, conditions on game state, choices that matter.
  6. Save/load — persist character, inventory, quest progress, world flags, with versioning.
  7. Economy + progression gating — gold/shops; gate power behind level/quest/region.
  8. UI — HUD, inventory, quest log, dialogue box, character sheet.

Patterns

1. Derived stats from base attributes (recompute, never store as truth)
python
# Pseudocode. Base attributes are the only "truth"; combat stats are derived each time.
def derive(base, mods):
    s = apply_modifiers(base, mods)          # base + flat adds + percent, then clamp
    return {
        "max_hp":  20 + s["VIT"] * 8,
        "attack":  s["STR"] * 2,
        "defense": s["VIT"] + s["AGI"] * 0.5,
    }
# Equipping pushes a modifier; unequipping pops it. HP/attack recompute automatically.
2. XP curve + level-up
python
# Pseudocode. Quadratic curve: fast early levels, long late ones.
def xp_to_next(level, base=100): return base * level * level

def gain_xp(actor, amount):
    actor.xp += amount
    while actor.xp >= xp_to_next(actor.level):
        actor.xp -= xp_to_next(actor.level)
        actor.level += 1
        actor.base["STR"] += 2; actor.base["VIT"] += 2   # grant gains / skill points
        on_level_up(actor)                                # heal, unlock, notify
3. Quest objective update driven by game events
python
# Pseudocode. Game events advance matching objectives; completion grants rewards.
def on_event(kind, data):
    for q in active_quests:
        for obj in q.objectives:
            if obj.event == kind and matches(obj, data) and not obj.done:
                obj.count += 1
                if obj.count >= obj.needed: obj.done = True
        if all(o.done for o in q.objectives):
            q.state = "complete"                # turn-in grants xp/gold/items

Pitfalls / failure modes

  • Editing base stats for buffs/gear → values drift and corrupt on save/reload. Keep a modifier layer; push/pop it (Pattern 1).
  • Storing derived stats as truth → desync after a stat change. Recompute from base.
  • Runaway XP/damage numbers → either an exponential curve with no cap or a subtractive formula at huge values. Pick a curve and a formula family deliberately (refs).
  • Content as code → every item/quest hardcoded. Define items, enemies, and quests as data (godot-resources / unity-scriptableobjects).
  • Save format with no version field → old saves break on update. Add a version and a migration path from day one (see save-systems).
  • Choices without consequences → dialogue branches that reconverge immediately feel hollow. Set flags that actually change later quests/world state.
  • Quest progress not persisted → reloading loses mid-quest state. Save quest state, not just completion.

Composition (build it from these skills)

  • Dialogue: dialogue-systems (Yarn Spinner / Ink) — branching lines, conditions, variables.
  • Persistence: save-systems — character, inventory, quest flags, world state, versioning.
  • Content data: godot-resources / unity-scriptableobjects — items, enemies, quests, skills as assets.
  • Combat AI: game-ai for enemy behavior; for turn order reuse the scheduler idea in roguelike.
  • UI: game-ui-ux for HUD/menu layout, resolution scaling, and controller/keyboard nav; godot-ui-control for the concrete inventory, quest log, character sheet, and dialogue box.
  • World: level-design plus your engine's tilemap/3D skill (godot-tilemap, godot-3d-essentials).
