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 5.1 | $0.00046 | $0.01699 |
| Opus 5.5 | $0.00018 | $0.00680 |
| Sonnet 5.5 | $0.00009 | $0.00340 |
| Haiku 4.5 | $0.00005 | $0.00170 |
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 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.
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 (
TOUCHfor 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_TOUCHfor writes (idempotent, safe to retry) - Check all three permissionship values:
HAS_PERMISSIONgrants access; bothNO_PERMISSIONandCONDITIONAL_PERMISSIONdeny -- treat them identically unless your code explicitly supplied caveat context (see/spicedb-dev:implement-spicedb-checksfor handling) - Save
WrittenAtZedToken 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 1mo ago), licensed Apache-2.0. It adds 46 tokens to every session and 1,699 once invoked, about $0.0002 per session on Opus 5.5. 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.
