What it does

CLI Hub Matrix Game Development is an agent skill from HKUDS/CLI-Anything. Capability-based multi-tool matrix for game development: engine, 3D/2D/audio assets, AI-generated assets, agent playtesting, packaging, store publishing, and telemetry.

Its SKILL.md is about 2.3k 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 development. It works with Python. The repository describes itself as: "CLI-Anything: Making ALL Software Agent-Native" -- CLI-Hub: https://clianything.cc/. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Game development

Example prompts

  • “/cli-hub-matrix-game-development”

Requirements

  • Python 3
  • A credential in ITCH_API_KEY
  • A credential in EPIC_DEV_TOKEN

Workflow steps

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

  1. Use preflight as an availability report, not as a provider selector.
  2. Treat provider order as documentation order only.
  3. Choose from user requirements, output quality bar, offline needs, credential state, install cost, and provider notes.
  4. Escalate to paid or metered APIs only when credentials are already present or the user explicitly consents.

What it can do on your machine

Read from SKILL.md and the folder at commit 34f5195. 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

    Shell commands in SKILL.md call:

    • 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 these keys or tokens, usually read from environment variables:

    • ITCH_API_KEY
    • OPENAI_API_KEY
    • SCENARIO_API_KEY
    • LEONARDO_API_KEY
    • STEAM_PASSWORD
    • REPLICATE_API_TOKEN
    • STABILITY_API_KEY
    • EPIC_DEV_TOKEN
    • PLAY_CONSOLE_KEY
    • APP_STORE_CONNECT_KEY
    • POSTHOG_API_KEY
    • GAMEANALYTICS_KEY

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

Context cost

CLI Hub Matrix Game Development loads about 2.3k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 826 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k

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.

Capability-based multi-tool matrix for game development: engine, 3D/2D/audio assets, AI-generated assets, agent playtesting, packaging, store publishing, and telemetry.

Game Development Matrix (S4 — v2 capability-based)

Scenario S4. All asset-creation capabilities covered via the S3/S5 stacks; the structural gap is distribution (Steam/itch/console stores) and alternative engines (Unity/Unreal).

Schema: docs/cli-matrix/matrix_registry.schema.md. Matrix plan: docs/cli-matrix/cli-matrix-plan.md.

Install

bash
cli-hub matrix install game-development
cli-hub matrix info    game-development
cli-hub matrix preflight game-development --json

Provider selection constraints

  1. Use preflight as an availability report, not as a provider selector.
  2. Treat provider order as documentation order only.
  3. Choose from user requirements, output quality bar, offline needs, credential state, install cost, and provider notes.
  4. Escalate to paid or metered APIs only when credentials are already present or the user explicitly consents.

Preflight

Run cli-hub matrix preflight game-development --json first. Use the manual block below for extra probes or older cli-hub versions.

bash
cli-hub list --json
python - <<'PY'
import importlib.util
for m in ("pygame","arcade","panda3d","ursina","trimesh","pygltflib","PIL",
          "pydub","librosa","music21","mido","abjad","diffusers","replicate",
          "posthog","gymnasium"):
    print(m, importlib.util.find_spec(m) is not None)
PY
for b in godot blender aseprite butler steamcmd ffmpeg pyinstaller; do
  command -v "$b" >/dev/null && echo "$b: yes" || echo "$b: no"
done
for e in STEAM_USERNAME STEAM_PASSWORD ITCH_API_KEY EPIC_DEV_TOKEN \
         PLAY_CONSOLE_KEY APP_STORE_CONNECT_KEY \
         REPLICATE_API_TOKEN OPENAI_API_KEY STABILITY_API_KEY IDEOGRAM_API_KEY \
         POSTHOG_API_KEY GAMEANALYTICS_KEY PLAYFAB_TITLE_KEY SENTRY_DSN; do
  [ -n "${!e}" ] && echo "$e: set" || echo "$e: unset"
done

Suggest-to-user template

To enable <capability> via <provider>, please set <ENV_VAR>.
  Cost: <cost notes>
  Quality: <quality tier>
Reply 'skip' to fall back to <next provider>.

Example: To publish to Steam, please install steamcmd and set STEAM_USERNAME + STEAM_PASSWORD (use a dedicated build account to limit credential risk). Cost: one-time $100 Steamworks fee. Reply 'skip' to fall back to itch.io via butler which only needs ITCH_API_KEY.

Recipes

  • godot-jam-game — minimal end-to-end for a game jam. Uses: game.engine, asset.2d, asset.audio, build.package, (optional publish.store).

  • agent-bot — train / evaluate an agent against an existing game. Uses: playtest.agent, telemetry.ingest.

  • ai-indie-short — AI-generated art + simple engine loop. Uses: ai.gen-asset, asset.2d, game.engine, asset.audio, build.package.

  • steam-release — ship to Steam with crash reporting. Uses: build.package, publish.store, telemetry.ingest.

  • music-driven-game — composed score integrated with gameplay. Uses: asset.notation, asset.audio, game.engine.

  • reality-to-game — photogrammetry asset → import → ship. Uses: (S3 photogrammetry.reconstruct), asset.3d, game.engine, build.package.

Known gaps

  • publish.store — Steam/itch/console wrappers are native-only; escalate with explicit credentials.
  • game.engine for Unity/Unreal — only Godot harness exists.
  • telemetry.ingest — Sentry works; no first-party for GameAnalytics/PlayFab.
  • asset.notation — uniquely strong (MuseScore) but rarely used in practice; keep as a differentiator.

Agent guidance

  • Start in Godot unless the user has explicitly asked for Unity/Unreal — it's the only engine we harness.
  • Keep asset pipelines deterministic — re-runnable seeds for ai.gen-asset, versioned source .aseprite/.krita files, scriptable Blender bakes.
  • playtest.agent needs a bridge. Most commercial games lack API access; agents should ask the user if modding is permitted before attempting.
  • Version builds immediately. build.package output goes into builds/<version>/ with a manifest so publish.store has deterministic uploads.
  • Don't auto-publish. publish.store must always be gated behind explicit user confirmation — uploading a broken build is expensive to roll back.
