Migrating to SpiceDB

Migrating to SpiceDB is a skill for Claude Code from authzed/authzed-marketplace. It costs 58 tokens per session (3,557 once invoked), scanned A, original, Apache-2.0.

A source-independent process for moving an application's authorization system to SpiceDB, including its model, relationship data, client code, and tests. It currently supports migrations from OpenFGA, Okta FGA, and Auth0 FGA through a separate conversion pack.

In plain words
What is it for?
Use it to run the migration phases, convert the authorization schema and data, rewrite application calls, and bring the source system's tests across to SpiceDB.
Why use it?
It surfaces blocking decisions such as identifier conflicts, unsupported features, and multi-tenant design before conversion begins, so the migration does not proceed on unresolved assumptions.

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

Migrating to SpiceDB 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 10d 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.

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.

Migrating to SpiceDB

This skill defines the source-agnostic pipeline for converting an application's authorization system to SpiceDB: schema, data, client code, and tests. Source-specific rules live in a separate conversion pack skill; this skill defines the pipeline those packs plug into, and the protocol commands and packs use to talk to each other.

Overview

A migration converts four things, in a fixed order: the authorization model to a .zed schema, existing relationship data, application client code, and the source system's test suite. Every decision that could go wrong -- an identifier collision, a construct SpiceDB can't express, a multi-tenancy choice -- is surfaced once, up front, at a single gate, because these decisions interact (tenancy choice constrains identifier strategy constrains code rewriting). Nothing is converted past an unresolved hard blocker.

Source registry

Source system Pack skill Status
OpenFGA / Okta FGA / Auth0 FGA openfga-to-spicedb supported

If the detected source has no pack, stop and say so. Do not improvise a translation -- an unsupported source needs a new pack, not an ad hoc conversion.

Phase pipeline

This is the designed pipeline, and every phase of it is built. The status column stays authoritative -- read it rather than this sentence, and never route a user to a phase whose status is anything other than shipped.

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.
