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.

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 | $0.08334 | $0.08334 |
| Opus 5 | $0.04167 | $0.04167 |
| Sonnet 5 | $0.01667 | $0.01667 |
| Haiku 4.5 | $0.00833 | $0.00833 |
Grade A, and why
claude-code-plugins AGENTS.md 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 2d 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 — 424 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
You maintain a dual-host Claude Code and Codex plugin marketplace. This file is your operating manual - follow it when working on any plugin in this repo.
Repository Overview
This is vladolaru-claude-code-plugins - Vlad Olaru's personal Claude Code and Codex plugin marketplace featuring specialized plugins for development workflows, WordPress backend development, and AI-powered tools.
Development Model
This project is AI-written and AI-maintained. The human (Vlad) sets direction, makes architectural decisions, and reviews work. Claude Code agents do the implementation, testing, analysis, and maintenance. "Single maintainer" does not mean capacity-constrained — it means single human decision-maker with AI execution capacity. Do not assume limited implementation bandwidth when reasoning about priorities or feasibility.
No agent carries context between sessions — every agent reads the code cold. This has practical implications:
- Prefer single canonical implementations over duplicated patterns. An agent will copy whichever pattern it encounters first; if two conventions exist for the same thing, drift is inevitable.
- Constants, types, and named helpers are discovery mechanisms. They are more valuable here than in a human-authored codebase — they are the primary way agents find the "right" way to do something.
- Consolidating duplicated logic is drift prevention, not polish. Treat it accordingly when prioritizing work.

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.
- 2d ago First seen · 424 lines · 8,334 tokens per session scan A 7d39e2bdb190
claude-code-plugins AGENTS.md is an instructions file published in the GitHub repository vladolaru/claude-code-plugins (8 stars, last pushed 4d ago), licensed MIT. It adds 8,334 tokens to every session, about $0.0417 per session on Opus 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 2026-08-31.
