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: 4 findings, 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 →

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 | $0.00047 | $0.00612 |
| Opus 5.5 | $0.00019 | $0.00245 |
| Sonnet 5.5 | $0.00009 | $0.00122 |
| Haiku 4.5 | $0.00005 | $0.00061 |
Grade A, and why
ontoly-software-graph 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 1mo 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ontoly Software Graph
Use this skill when the user asks Codex to understand a TypeScript repository's architecture, dependency graph, request flow, service ownership, configuration usage, impact radius, package topology, or security-sensitive code paths.
Ontoly is a deterministic Software Graph compiler. It does not answer questions with AI. It builds graph evidence that Codex can query before falling back to source search.
Workflow
-
Check whether
.ontoly/SoftwareGraph.jsonexists. -
If the graph is missing or stale, ask before installing dependencies or writing generated graph files. Then run:
pnpm add -D @0xsarwagya/ontoly-cli pnpm ontoly build . -
Inspect graph quality before answering:
pnpm ontoly coverage . pnpm ontoly stats . -
Prefer Ontoly graph queries before repository-wide source search:
pnpm ontoly architecture --json pnpm ontoly report dependencies --format markdown pnpm ontoly report routes --format markdown pnpm ontoly query impact <node-id> pnpm ontoly trace <node-id-or-name> -
Start Ontoly MCP when the environment supports MCP-backed tools:
pnpm ontoly mcp -
Use source files only when the graph is missing, stale, low confidence, or insufficient for the question.
Common Questions
- "Explain this repository."
- "Which service owns authentication?"
- "Trace the login flow."
- "What breaks if I remove this repository/service/function?"
- "Which packages depend on this module?"
- "Where is this environment variable read?"
- "Which routes are protected by auth?"
Evidence Rules
When answering, cite graph evidence:
- graph hash
- node ids
- relationship types
- source spans when available
- diagnostics or confidence warnings
- fallback reason if source files were inspected
Never claim certainty beyond Ontoly evidence. If graph coverage is incomplete, say exactly which part is inferred or unresolved.

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.

ontoly-software-graph is a skill published in the GitHub repository hashgraph-online/awesome-codex-plugins (1,364 stars, last pushed today), licensed Apache-2.0. It adds 47 tokens to every session and 612 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
