permission-matrix

permission-matrix is a cursor rule for Cursor from bayesimpact/bayes-platform. It costs 0 tokens per session (369 once invoked), scanned A, original, MIT.

A documentation synchronisation rule for an application's role-based access control (RBAC) permissions. RBAC means deciding which actions each user role may perform; the rule requires the permissions document to match the source code.

In plain words
What is it for?
Use it whenever roles, permissions, or role grants are added, renamed, or removed, so the corresponding Markdown tables are updated in the same change.
Why use it?
It prevents the access-control documentation from becoming out of date when roles or permissions change. That makes the written permission tables a more reliable reference for review and maintenance.

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

permission-matrix 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 20d 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.

What it actually says

Permission Matrix Sync

How to declare a permission, protect a route, and list what the caller can see: .claude/skills/rbac/SKILL.md and ADR 0019. This rule only keeps the matrix in sync with the catalog.

docs/rbac-permission-matrix.md mirrors the RBAC catalog defined in:

  • packages/api-contracts/src/rbac/permissions.ts — permission string constants and the GlobalPermission contract. Declare a permission string only here.
  • apps/api/src/domains/rbac/rbac.constants.ts — role keys and which role receives which permission. Import the permission strings from @caseai-connect/api-contracts. Do not redeclare them.

Whenever you add, rename, or remove a role, a permission, or a role/permission grant in those files, you MUST update the corresponding table in docs/rbac-permission-matrix.md in the same change set.

Checklist:

  • Every role in ORGANIZATION_ROLE_PERMISSIONS / PROJECT_ROLE_PERMISSIONS / AGENT_ROLE_PERMISSIONS / REVIEW_CAMPAIGN_ROLE_PERMISSIONS has a column in the doc
  • Every granted permission has a row, checkmarks match the constants exactly
  • GlobalPermission union members all appear in the "Global roles" table
  • The project rows of the review campaign table match PROJECT_PERMISSIONS_FROM_REVIEW_CAMPAIGN and REVIEW_CAMPAIGN_STATUSES_GIVING_PROJECT_PERMISSIONS

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.
