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 | $0.00000 | $0.00356 |
| Opus 5 | $0.00000 | $0.00178 |
| Sonnet 5 | $0.00000 | $0.00071 |
| Haiku 4.5 | $0.00000 | $0.00036 |
Grade A, and why
application-config 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 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.
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.
What it actually says
Application Configuration
KoaApplication Setup
Standard HTTP server configuration:
const { KoaApplication, Router } = require("@axiosleo/koapp");
const app = new KoaApplication({
port: 8080,
listen_host: "localhost", // Use '0.0.0.0' for public access
debug: false,
routers: [router1, router2],
// Session configuration
session: {
maxAge: 1296000000, // 15 days in ms
httpOnly: true,
signed: true,
rolling: false,
renew: true,
},
// Static file serving
static: {
rootDir: "./public",
// uploadDir: './public/upload' // Optional upload directory
},
// Body parser options
body_parser: {},
// Server-Sent Events
sse: false, // or { pingInterval: 60000, closeEvent: "close" }
});
app.start();
Environment-Specific Configuration
- Use
debug: truefor development - Set
listen_host: '0.0.0.0'for production deployment - Configure session security based on environment
- Enable HTTPS in production with
secure: truefor sessions
Application Events
Applications emit events that can be handled:
starting- Before server startsresponse- After each response
Required Node.js Version
Minimum Node.js version: 16.0.0 (as specified in package.json)
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.

application-config is a cursor rule published in the GitHub repository AxiosLeo/node-koapp (129 stars, last pushed 18d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 356 tokens. 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.
