What it does

Board Game Designer is an agent skill from mohitagw15856/pm-claude-skills. Take a board game idea from 'wouldn't it be cool if' to a playtestable prototype — core loop, tension source, components you can make tonight, balance starting-points, and a real playtest protocol with kill criteria. Use when someone says 'I have a board game idea', 'design a game about X', 'my game drags in the midgame', or 'how do I playtest this'. Produces a design one-pager, a print-and-play prototype spec, and a 3-session playtest plan.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Game Development, covering Game design. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

When your agent uses it

  • Someone says I have a board game idea
  • Design a game about X
  • My game drags in the midgame
  • How do I playtest this

Example prompts

  • “wouldn”
  • “I have a board game idea”
  • “design a game about X”
  • “/board-game-designer”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Find the loop. One sentence: "On your turn you [verb] to get [resource]
  2. Name the tension. Every game that works has a recurring painful choice
  3. Steal structure honestly. Name 2–3 existing games whose mechanisms
  4. Spec the ugliest playable version. Index cards and cubes, tonight. Every
  5. First-pass the numbers. Costs, income, end-trigger pacing — pick values
  6. Protocol the playtests. Session 1 (solo, all seats): does the loop

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. 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.

    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

Board Game Designer loads about 1.3k tokens when it runs. Until then it costs about 116 tokens; SKILL.md has 597 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~116
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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
Take a board game idea from 'wouldn't it be cool if' to a playtestable prototype — core loop, tension source, components you can make tonight, balance starting-points, and a real playtest protocol with kill criteria. Use when someone says 'I have a board game idea', 'design a game about X', 'my game drags in the midgame', or 'how do I playtest this'. Produces a design one-pager, a print-and-play prototype spec, and a 3-session playtest plan.

Board Game Designer Skill

Everyone has a board game idea; almost nobody has a prototype, because the gap between theme ("it's about deep-sea heists!") and game (what do I DO on my turn?) is where ideas stall. This skill forces the designer's questions in the order working designers ask them — loop before theme-decoration, tension before content, cardboard before art — and ships the user toward a playtest this week with ugly components and honest kill criteria.

What This Skill Produces

  • A design one-pager: hook, core loop, tension source, end condition, player count/length targets
  • A prototype spec buildable tonight: index cards, dice, cubes — counts and what's written on each; zero art
  • Balance starting-points: first-pass numbers with the reasoning, labelled as guesses to tune, never as solved math
  • A 3-session playtest protocol with what to watch, what to ask, and kill criteria — the honest thresholds for pivot-or-persevere

Required Inputs

Ask for (if not already provided):

  • The idea as they'd pitch it to a friend, plus what inspired it
  • The feeling the best turn should produce (clever? tense? gleeful betrayal?)
  • Target: players, minutes, audience (family? hobbyists? their own group?)
  • If mid-design: what's working, and where it drags

Process

  1. Find the loop. One sentence: "On your turn you [verb] to get [resource] to [convert] toward [goal]." No loop sentence, no game yet — iterate here before anything else.
  2. Name the tension. Every game that works has a recurring painful choice (this OR that, now OR better-later, me OR blocking-you). Identify the one this design offers; if every option is good, there's no game in the loop yet.
  3. Steal structure honestly. Name 2–3 existing games whose mechanisms neighbour this design and what each does with them — designers study prior art; note where this design genuinely differs (its one new twist) and where it shouldn't bother differing.
  4. Spec the ugliest playable version. Index cards and cubes, tonight. Every component count written down. The rule: nothing gets art until it survives five plays.
  5. First-pass the numbers. Costs, income, end-trigger pacing — pick values with stated reasoning ("end triggers around turn 8 so the engine peaks once"), marked TUNE. Balance comes from plays, not spreadsheets; the spreadsheet just picks where to start.
  6. Protocol the playtests. Session 1 (solo, all seats): does the loop function? Session 2 (friendly table): where does attention die? Watch for the tells — checking phones, analysis stalls, kingmaking, runaway leader. Session 3 (someone who owes you nothing): would they play again unprompted? Kill criteria stated up front: if the same drag survives two fixes, the mechanism goes, however loved.

Output Format

## Design one-pager
[Hook · loop sentence · the tension · end condition · count/length targets]

## Neighbouring designs
[2-3 games, the mechanism borrowed/varied, the one honest twist here]

## Prototype spec (build tonight)
[Component list with counts and card text · setup · turn structure v0.1]

## Numbers v0.1 (all marked TUNE)
[Table of starting values + one line of reasoning each]

## Playtest protocol
[3 sessions: goal, what to watch, questions to ask AFTER not during]
Kill criteria: [the honest thresholds]

Quality Checks

  • The loop fits in one sentence and contains a decision, not just an action
  • The tension is a recurring choice, named concretely
  • Prototype is buildable from household stationery in an evening — if it needs printing services, it's overdesigned for v0.1
  • Every number carries reasoning and a TUNE flag — no false precision
  • Kill criteria exist and are specific enough to actually trigger

Anti-Patterns

  • Do not start with theme, art, or a Kickstarter plan — loop, tension, cardboard, in that order
  • Do not claim the idea is original without the prior-art pass, and do not copy a game wholesale with the theme swapped — name the twist
  • Do not present first-pass numbers as balanced — playtesting owns balance
  • Do not let the designer explain rules during playtests — confusion IS the data
  • Do not promise market outcomes ("this would sell!") — the promise is a playtest by Friday

Example Trigger Phrases

  • "I have a board game idea."
  • "Design a game about X."
  • "My game drags in the midgame."
  • "How do I playtest this?"
