Continuous scanner CI not detected

This plugin remains listed. Its overall trust score is reduced by 10% because security checks are not maintained in the source repository's CI.

Optional: maintain the scanner in the source repository's CI to receive the full trust score. Listing does not require that change.

README badge not detected

Plugin owners can add the HOL badge to the repository README from Guard Plugins. Distribution, not security evidence. It adds a 2% engagement adjustment to the overall trust score and never changes the security result.

Install Guidance

Install in Codex

Install through the Codex CLI plugin marketplace.

Codex plugin docs

Optional: install HOL Guard for Codex first, so it can check this plugin's tools on your machine before Codex uses them.

  1. 1

    Register the marketplace

    Run in any terminal. Codex reads the marketplace entry from .agents/plugins/marketplace.json (or the legacy .claude-plugin path) in the repository. If the repository ships none, add the generated entry from the Advanced section below first.

    shell
  2. 2

    Install from the Plugins browser

    Open Codex, open the Plugins browser, choose the marketplace registered by the previous command, and install game-development-studio.

  3. 3

    Check the marketplace is registered

    This confirms the marketplace source only. Confirm the plugin itself is enabled in the Plugins browser before relying on it.

    shell

Did setup work in Codex?

No setup reports for Codex yet. Self-reported by signed-in visitors. Copying a command is not counted, and most installs are never reported.

Attested installs: Fewer than 10 attested installs of this plugin in week 2026-W43, so no number is shown. Counted from opt-in HOL Guard install reports, once per machine and runtime, and never mixed with the answers above. How install reports work.

5 SKILL.md files ship with this plugin. Preview, copy, or download each one, then install them with the Skills CLI.

Share
skills-cli

  • game-asset-production

    skills/game-asset-production/SKILL.md

    Create, inspect, normalize, validate, and package game-development assets with local tools plus optional Tripo and Leonardo jobs. Use for 3D, texture, reference-image, sound-effect, Blender, GLB, PBR, or USDZ asset-production work; not for admitting packages into a game project.

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • game-asset-vendoring

    skills/game-asset-vendoring/SKILL.md

    Search, verify, migrate, and safely admit canonical asset packages into local game projects. Use for asset catalogs, license gates, package integrity, project vendoring, lock receipts, and local preview launch; not for generating paid-provider assets.

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • game-development-studio

    skills/game-development-studio/SKILL.md

    Route local game-asset production, package vendoring, offscreen render diagnosis, and bounded performance work through the game-dev CLI. Use only when a game-development request explicitly spans two or more of these workflows, needs a cross-workflow handoff, or asks for Game Development Studio orchestration; do not activate for unrelated development or general creative work.

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • game-performance-optimization

    skills/game-performance-optimization/SKILL.md

    Summarize sealed game-run telemetry, compare baseline and candidate metrics, and execute bounded code-optimization goals with explicit path and iteration limits. Use for measurable performance work after a reproducible adapter scenario exists; not for visual diagnosis without a metric.

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • game-visual-debugging

    skills/game-visual-debugging/SKILL.md

    Diagnose game-rendering problems with declarative local adapters, windowless captures, structured telemetry, semantic render attachments, sealed run bundles, and deterministic raster comparisons. Use for visual bugs or renderer regressions where screenshots alone are insufficient.
