Agentic Plugin Marketplace is a collection of reusable plugins, agents, skills, commands, and rules for coding-agent tools including Claude Code, Codex CLI, Cursor, OpenCode, Antigravity CLI, and GitHub Copilot. It is for developers assembling agentic workflows across multiple harnesses from shared Markdown sources, and the catalogue entries are examples or subsets of those workflow components.

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 | $0.01811 | $0.01811 |
| Opus 5.5 | $0.00724 | $0.00724 |
| Sonnet 5.5 | $0.00362 | $0.00362 |
| Haiku 4.5 | $0.00181 | $0.00181 |
Grade B, and why
agents AGENTS.md scanned grade B with 1 finding 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 yesterday.
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.

The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agents, skills, and commands for seven coding tools
The repository provides 94 plugins (92 local + 2 external), 202 agents, 185 skills, and 105 commands for seven coding tools: Claude Code, OpenAI Codex CLI, Cursor, OpenCode, Google Antigravity CLI (agy), GitHub Copilot, and Pi. Shared source files use the Claude Code format, and adapters provide the formats used by other tools. External entries have their own tool support.
AGENTS.md is the canonical context file. Codex, Cursor, OpenCode, Antigravity CLI, GitHub Copilot, and Pi read it directly. Claude Code reads it via CLAUDE.md, a symlink to this file.

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.

agents AGENTS.md is an instructions file published in the GitHub repository wshobson/agents (40,926 stars, last pushed yesterday), licensed MIT. It adds 1,811 tokens to every session, about $0.0072 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
