Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00033 | $0.04775 |
| Opus 5.5 | $0.00013 | $0.01910 |
| Sonnet 5.5 | $0.00007 | $0.00955 |
| Haiku 4.5 | $0.00003 | $0.00477 |
Grade A, and why
cloudflare-durable-objects:debug 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 1mo 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.

Durable Objects Debug Command
Interactive command to diagnose and fix common Durable Objects issues. Provides step-by-step troubleshooting for configuration errors, runtime failures, and performance problems.
Overview
This command helps debug DO issues by:
- Detecting common error patterns from error messages
- Running diagnostic checks on configuration and code
- Providing specific fixes for identified issues
- Testing solutions before deployment
- Monitoring DO behavior with wrangler tail
Step 1: Gather Error Context
Use AskUserQuestion tool to understand the problem:
Question 1: Error Category
Question: "What type of issue are you experiencing with Durable Objects?" Header: "Issue Type" Options:
- Deployment Error - wrangler deploy fails with DO-related error
- Description: "Migration errors, binding issues, class export problems"
- Runtime Error - DO throws error during execution
- Description: "Constructor failures, storage errors, WebSocket issues"
- Performance Issue - DO is slow or timing out
- Description: "Slow queries, hibernation problems, memory issues"
- Data Loss - DO state not persisting correctly
- Description: "Data disappearing, inconsistent state, sync issues"
- WebSocket Problem - WebSocket connections failing or not hibernating
- Description: "Connection drops, hibernation failures, message loss"
- Alarm Not Firing - Scheduled alarms not executing
- Description: "Alarms not triggering, retry loops, timing issues"
- Other/Unknown - Not sure or different issue
- Description: "General debugging assistance needed"
Question 2: Error Message (If Applicable)
If user selected error-based category (Deployment, Runtime):
Prompt: "Please paste the full error message:"
Enter error message (or 'none' if no specific error):

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.
