Awesome Codex Plugins is a curated catalogue and marketplace of installable plugins, skills, and related resources for OpenAI Codex and ChatGPT. It helps people find, create, validate, and submit extensions for Codex workflows across its app, command-line interface, and IDE extensions. The catalogue add-ons are the plugins, skills, agents, and hooks listed or supported by this project.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 163 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00158 | $0.04521 |
| Opus 5.5 | $0.00063 | $0.01808 |
| Sonnet 5.5 | $0.00032 | $0.00904 |
| Haiku 4.5 | $0.00016 | $0.00452 |
Grade A, and why
unity-agent-workflows scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unity Agent Workflows
AI contract for Unity work. Keep answers compact, but never remove exact paths, object/class names, commands, errors, validation, rollback notes, or proof requirements.
Core Loop
- No proof, no edit.
- Treat this injected
SKILL.mdas authoritative; do not search for its own path unless missing or asked for diagnostics. - Read live project instructions narrowly:
AGENTS.mdif present,git status --short, and existingUNITY_STRUCTURE.mdplus only the focused map that matches the task when available. ReadREADME.md, architecture docs,.agents/*, or repo-local agent files only when the task cites them, needs architecture/new-file/asmdef/routing decisions, or maps are missing/stale. - Run
git status --short; preserve unrelated dirty files. - If user says only
$unity-agent-workflows. Teach, run Teach. - Derive only relevant live structure before architecture claims: folders, namespaces,
.asmdef, scenes/prefabs, bootstraps, graphs, docs,UNITY_STRUCTURE*. - Classify task with
Task Gate, then load required references before edits. - Inspect real owner files; never start from memory, nearest-name guessing, semantic similarity, or screenshot proximity alone.
- Fill useful
Routing Cardfields for structure, visible output, state flow, multi-agent, or hub changes. - Patch the smallest proven owner/artifact.
- Validate, sync mirrors if package skill files changed, then close out with proof.
Task Gate
| Trigger | Required action |
|---|---|
| Runtime/visible bug | Prove owner chain before editing. |
| Runtime-visible output, target alignment, focus/highlight/marker/HUD, overlay, input blocker, modal dimming, duplicate names, hardcoded layout, "do not guess" | Runtime Visible Output Hard Stop. |
| Screenshot or visible UI text fix | Screenshot Text Owner Gate; search exact visible text/localization key and prove creator plus refresh writer before editing. |
| Visual/model/sprite/asset integration where feature name, source asset, factory, or visible surface may disagree | Visible Object Identity Lock, Multi-Surface Visible Behavior Lock, and Single-Agent Anti-Anchoring Guard before editing. |
| Same visible behavior requested across multiple scenes/surfaces, or words like "also", "after transition", "menu and gameplay", "preview and runtime", "scene A and scene B" | Multi-Surface Visible Behavior Lock; prove each surface owner, active caller, asset/factory dependency, and fallback behavior before editing any surface. |
| Shared factory/helper/style/global method candidate for a scoped visible surface | Shared Caller Blast Radius Gate: prove allowed runtime caller(s), all other callers, and whether the patch is surface-local before editing. |
| Overlay/dim source-bound mistakes | Prove source target bounds; overlay/dim/mask/blocker rects are destination output unless explicit marker proof exists. |
| Predictive aim, turret targeting, ballistic trajectory with drag, collision tunneling, CCD, proportional navigation (TPN), physics movement | Kinematic predictive intercept, drag ballistics, and TPN equations in references/runtime-numeric-proof.md; solve 2nd-order quadratic intercept with CPA fallback. |
| 2D game physics, 2D platformer jump apex/gravity, Rigidbody2D drag, Box2D tunneling/Continuous Collision Detection (CCD), 2D predictive lead intercept, 2D steering/TPN, 2D orthographic camera, ScreenToWorldPoint z-plane distance, RectTransform in Canvas 2D (Overlay camera null & World Space 1/PPU scale), 2D pixel-perfect PPU snapping, Tilemap cell-to-world pivot | 2D kinematic equations, Box2D drag damping, 2D parabolic jump kinematics ($g = 2h/t_{\text{apex}}^2$), Orthographic projection, 2D Canvas RectTransform invariants, 2D CCD raycast, and Tilemap half-tile pivot invariants in references/coordinate-space-conversion.md and references/runtime-numeric-proof.md. |
| Offscreen pointer, behind-camera target, near-clip singularity, optical axis degeneracy, 3D bounds frustum clipping, CanvasScaler aspect drift, stretch anchor mismatch | Projective geometry, near-clip plane w <= 0 clamping, optical axis guard, Sutherland-Hodgman 3D near-plane clipping, CanvasScaler log formula, and RectTransform invariants in references/coordinate-space-conversion.md. |
| Quaternion rotation flip, gimbal lock, Euler snap, rotational slerp/nlerp, symplectic physics stability | Quaternion antipodal shortest-path condition (q1·q2 < 0), small-angle Nlerp fallback, and Symplectic Euler integration in references/runtime-numeric-proof.md. |
| Focus ring / UI overlay alignment precision, quantitative spatial verification | Intersection over Union (IoU >= 0.95) and sub-pixel tolerance in references/runtime-numeric-proof.md. |
| Repeated visible-output mismatch after patch | Runtime numeric proof before another coordinate/layout/fallback patch. |
| Multi-agent visible-output or state work | Sub-agent decision and permission gate first; main-agent scope lock before workers patch; checker must review. |
| New/moved files, expanded C# responsibility, asmdef/module routing, hub deflation | Project-derived routing, no fixed structure, hub stop gate. |
| UI, screenshot, HUD, menu, safe area, TMP, spotlight, item-based UI assembly, picked UI parts, UI slices, extracted UI parts, textless UI sprites, design manifests | UI workflow plus runtime-owner proof, extracted item assembly proof, and validation. |
| Visual source asset | Source asset/generator gate before Unity integration code. |
| Content, progression, economy, levels, objectives, gameplay tuning | Data-first content workflow. |
| Tutorial, onboarding, objective, unlock, selection, action, navigation, state transition, guided selection/action flows | State-step guards. |
| Compile/runtime doubt, stale Bee/Roslyn response files, Play Mode proof | Validation workflow. |
| Cleanup/deletion/generated files/git hygiene | Cleanup proof. |
| Rule/session mining/workflow update | Patch only the owning artifact. |
What ships with it
31 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
