Prowler is an open-source cloud security platform that checks cloud environments for security issues and compliance with standards such as CIS, NIST, and GDPR. Security teams use it to assess configurations, prioritize findings, produce reports, and guide remediation.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.04324 |
| Opus 5.5 | $0.00021 | $0.01730 |
| Sonnet 5.5 | $0.00011 | $0.00865 |
| Haiku 4.5 | $0.00005 | $0.00432 |
Grade A, and why
prowler-api 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.
How it starts
The opening of the file, as written. The whole thing — 506 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to Use
Use this skill for Prowler-specific patterns:
- Row-Level Security (RLS) / tenant isolation
- RBAC permissions and role checks
- Provider lifecycle and validation
- Celery tasks with tenant context
- Multi-database architecture (4-database setup)
For generic DRF patterns (ViewSets, Serializers, Filters, JSON:API), use django-drf skill.
Critical Rules
- ALWAYS use
rls_transaction(tenant_id)when querying outside ViewSet context - ALWAYS use
get_role()before checking permissions (returns FIRST role only) - ALWAYS use
@set_tenantthen@handle_provider_deletiondecorator order - ALWAYS use explicit through models for M2M relationships (required for RLS)
- NEVER access
Provider.objectswithout RLS context in Celery tasks - NEVER bypass RLS by using raw SQL or
connection.cursor() - NEVER use Django's default M2M - RLS requires through models with
tenant_id
Note:
rls_transaction()accepts both UUID objects and strings - it converts internally viastr(value).
Architecture Overview
4-Database Architecture
| Database | Alias | Purpose | RLS |
|---|---|---|---|
default |
prowler_user |
Standard API queries | Yes |
admin |
admin |
Migrations, auth bypass | No |
replica |
prowler_user |
Read-only queries | Yes |
admin_replica |
admin |
Admin read replica | No |
# When to use admin (bypasses RLS)
from api.db_router import MainRouter
User.objects.using(MainRouter.admin_db).get(id=user_id) # Auth lookups
# Standard queries use default (RLS enforced)
Provider.objects.filter(connected=True) # Requires rls_transaction context
RLS Transaction Flow
Request → Authentication → BaseRLSViewSet.initial()
│
├─ Extract tenant_id from JWT
├─ SET api.tenant_id = 'uuid' (PostgreSQL)
└─ All queries now tenant-scoped
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

prowler-api is a skill published in the GitHub repository prowler-cloud/prowler (15,037 stars, last pushed yesterday), licensed Apache-2.0. It adds 53 tokens to every session and 4,324 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 2026-08-30.
