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 | $0.00032 | $0.03807 |
| Opus 5 | $0.00016 | $0.01903 |
| Sonnet 5 | $0.00006 | $0.00761 |
| Haiku 4.5 | $0.00003 | $0.00381 |
Grade A, and why
cloudflare-durable-objects:migrate 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 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.

Durable Objects Migration Command
Interactive command to safely create and manage Durable Objects migrations. Handles new classes, renaming, deletion, and transfers with automatic validation and backup.
Overview
This command simplifies DO migration management by:
- Generating correct migration syntax for all migration types
- Validating migration configuration before committing
- Auto-incrementing migration tags (v1, v2, v3...)
- Backing up wrangler.jsonc before changes
- Checking for common migration errors
- Providing rollback instructions
Step 1: Analyze Current Configuration
Before prompting user, analyze the current project state:
Read wrangler.jsonc
cat wrangler.jsonc
Parse configuration to extract:
- Existing Durable Object bindings
- Current migrations array
- Last migration tag (for auto-increment)
- Class names currently in use
Identify Migration Context
Determine project state:
Case 1: No Existing Migrations
- First-time migration setup
- Recommend new_sqlite_classes for all DOs
- Suggest v1 as initial tag
Case 2: Existing Migrations
- Extract last migration tag
- Suggest next sequential tag (v2, v3, etc.)
- Show migration history for context
Case 3: No DO Bindings
- No DOs configured yet
- Recommend running
/do-setupfirst - Offer to continue anyway (for planning)
Display Current State
Show user the current configuration:
Current Durable Objects Configuration:
Bindings:
- MY_DO → MyDurableObject
- CHAT_ROOM → ChatRoom
Migrations:
- v1: new_sqlite_classes [MyDurableObject]
- v2: new_sqlite_classes [ChatRoom]
Next migration tag: v3
Step 2: Gather Migration Requirements
Use AskUserQuestion tool to determine migration type and details:
Question 1: Migration Type
Question: "What type of migration do you need to perform?" Header: "Migration Type" Options:
- New Class - Add a new Durable Object class
- Description: "Create migration for newly added DO class (new_sqlite_classes)"
- Rename Class - Rename existing Durable Object class
- Description: "Migrate DO instances to renamed class (renamed_classes)"
- Delete Class - Remove Durable Object class
- Description: "Delete all DO instances and remove class (deleted_classes)"
- Transfer Class - Move DO class to different Worker script
- Description: "Transfer DO instances to another script (transferred_classes)"
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.

cloudflare-durable-objects:migrate is a command published in the GitHub repository secondsky/claude-skills (214 stars, last pushed yesterday), licensed MIT. It adds 32 tokens to every session and 3,807 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
