SpiceDB Best Practices

SpiceDB Best Practices is a skill for Claude Code from authzed/authzed-marketplace. It costs 46 tokens per session (1,699 once invoked), scanned A, original, Apache-2.0.

A reference guide for using SpiceDB client libraries in Go, TypeScript, and Python. It covers how application code connects to SpiceDB and handles permission-related requests.

In plain words
What is it for?
It guides client setup, consistency choices, error handling, retries, performance tuning, caching, caveats, data bootstrapping, and production deployment.
Why use it?
It helps avoid incorrect permission results, unsafe error handling, unreliable retries, and inefficient checks.

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

SpiceDB Best Practices 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.

The scan reads SKILL.md. This mod also ships 2 executable files (examples/python-client.py, examples/typescript-client.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

SpiceDB Best Practices

This skill provides guidance on using SpiceDB client libraries effectively, understanding consistency guarantees, optimizing performance, and implementing robust authorization code.

Overview

SpiceDB is a distributed authorization system. To use it effectively:

  • Understand consistency models (when reads reflect writes)
  • Handle errors and retries properly
  • Use appropriate client patterns for your language
  • Optimize for performance without sacrificing correctness
  • Use caveats judiciously for dynamic permissions

Client Library Usage

SpiceDB provides official clients for multiple languages. Each follows similar patterns but with language-specific idioms.

See references/client-patterns.md for full code examples (Go, TypeScript, Python) covering:

  • Connection management (development vs. production TLS)
  • Writing relationships (TOUCH for idempotency)
  • Checking permissions (single and bulk)
  • Lookup operations (LookupResources, LookupSubjects)

See examples/go-client.go, examples/typescript-client.ts, examples/python-client.py for complete, runnable demos with all four operations.

Core rules:

  • Reuse clients -- don't create one per request
  • Use OPERATION_TOUCH for writes (idempotent, safe to retry)
  • Check all three permissionship values: HAS_PERMISSION grants access; both NO_PERMISSION and CONDITIONAL_PERMISSION deny -- treat them identically unless your code explicitly supplied caveat context (see /spicedb-dev:implement-spicedb-checks for handling)
  • Save WrittenAt ZedToken after writes (see Consistency section)

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.

SpiceDB Best Practices is a skill published in the GitHub repository authzed/authzed-marketplace (2 stars, last pushed 13d ago), licensed Apache-2.0. It adds 46 tokens to every session and 1,699 once invoked, about $0.0002 per session on Opus 5. 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 2026-08-31.
