Authorization Planner

Authorization Planner is a skill for Claude Code from authzed/authzed-marketplace. It costs 40 tokens per session (793 once invoked), scanned A, original, Apache-2.0.

A planning skill for adding fine-grained authorization with SpiceDB, a system for deciding who can perform which actions on which resources. It guides the design of permission relationships and schemas.

In plain words
What is it for?
Use it to plan authorization, model entities and permissions, generate a SpiceDB schema, and account for relationship changes while building features.
Why use it?
It helps establish permission rules early, before they become scattered or inconsistent across application code.

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

Authorization Planner 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 5d 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.

Authorization Planner

This plugin adds a first pass at SpiceDB fine-grained authorization to an application being built or modified. The goal is getting authorization structurally correct -- right permissions, right places, right operations. It is not a production hardening or debugging tool.

Ideal Workflow

Once, early -- before or alongside data model design

Run /spicedb-dev:plan. This scopes the work, produces authorization-plan.md, and writes an authorization snippet to CLAUDE.md so permissions are considered automatically in every future session without needing to invoke any command. This is the most important setup step.

Then /spicedb-dev:design-model -- scans for existing model files and extracts entity names. Produces permission-model.md.

Then /spicedb-dev:generate-schema -- converts the model to schema.zed. Schema-validator runs automatically.

Deploy the schema externally: zed schema write schema.zed.

Continuously, alongside every feature

Every feature needs both operations -- this is the most common implementation mistake:

  1. Relationship writes (/spicedb-dev:implement-spicedb-relationships) -- run when writing handlers that create resources, grant membership, or delete resources. SpiceDB returns NO_PERMISSION for everything until relationships are written. Writes must come before checks.

  2. Permission checks (/spicedb-dev:implement-spicedb-checks) -- run when writing any handler that reads, modifies, or deletes a resource on behalf of a user. For list endpoints, use LookupResources -- not CheckPermission in a loop.

Use /spicedb-dev:implement-spicedb when unsure which is needed -- it communicates the paired requirement and routes to the right command.

Periodically

/spicedb-dev:audit-coverage produces a coverage matrix: every permission in the schema vs. whether a corresponding check exists in code. Routes each gap to the correct implement command.

Once, when stable

/spicedb-dev:test-permissions generates test fixtures and integration tests from the schema.

Changes

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.

Authorization Planner is a skill published in the GitHub repository authzed/authzed-marketplace (2 stars, last pushed 9d ago), licensed Apache-2.0. It adds 40 tokens to every session and 793 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.
