deco-site-memory-debugging

A debugging tool for finding memory problems in Deco sites, which are web applications that can run on Cloudflare Workers or Node.js. It uses different inspection methods because these environments do not expose the same kind of running process.

In plain words
What is it for?
Use it to investigate excessive memory use in Cloudflare Workers sites with ClickHouse and Wrangler diagnostics. For Node or React Server Components sites, use its Node inspection flow.
Why use it?
It addresses memory failures where attaching a normal debugger to a live production process is not possible. It directs investigation to captured Cloudflare Worker data or Node’s inspection tools.

Token cost

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.

Security

Grade A, and why

deco-site-memory-debugging scanned grade A 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
