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 5.1 | $0.00081 | $0.00267 |
| Opus 5 | $0.00041 | $0.00133 |
| Sonnet 5 | $0.00016 | $0.00053 |
| Haiku 4.5 | $0.00008 | $0.00027 |
Grade B, and why
install-agent-config 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 8d 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.

Install agent-config
This plugin is a bootstrap shim. It exists so the marketplace listing stays discoverable and existing plugin installs keep working hooks — the content surface (skills, rules, commands, personas) is distributed as a file projection, not through this plugin.
Install (canonical, one command)
npx -y @event4u/agent-config init
The installer writes the full content projection, registers the dispatcher
hooks as a managed block in ~/.claude/settings.json (byte-identical to
this plugin's hooks, so nothing double-fires), and keeps everything
upgradeable via agent-config upgrade.
Already installed both?
Run agent-config doctor to check for duplicate surfaces, and

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.

install-agent-config is a skill published in the GitHub repository event4u-app/agent-config (10 stars, last pushed today), licensed MIT. It adds 81 tokens to every session and 267 once invoked, about $0.0004 per session on Opus 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 2026-08-31.
