What it does
Audit Serverless Security is an agent skill from cyberful/cyberful. Audit serverless applications for event-source authority, function identity, tenant context, data exposure, retry behavior, deployment controls, and unsafe service integrations. Use for Lambda, Cloud Functions, Azure Functions, edge functions, or event-driven serverless review.
Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files and assets (for example `agents/openai.yaml`, `assets/serverless-boundary-ledger.example.json` and `assets/serverless-boundary-ledger.schema.json`).
It sits in Backend & APIs, covering Serverless. It works with Azure Functions. The repository describes itself as: Cyberful is an open-source AI Red Team for discovering, exploiting, verifying, and remediating vulnerabilities. The licence is AGPL-3.0.
When your agent uses it

- Azure Functions
- Event-driven serverless review
Example prompts
- “/audit-serverless-security”
What it can do on your machine
Read from SKILL.md and the folder at commit ec598a6. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Audit Serverless Security loads about 577 tokens when it runs, and up to ~855 if it reads all its reference files. Until then it costs about 76 tokens; SKILL.md has 159 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Audit Serverless Security
Model the application as event sources, function identities, service integrations, asynchronous state, and deployment policies. Do not treat the function handler as the whole trust boundary: provider bindings and retry paths often decide authority before or after the code runs.
Trace event authority
Read references/serverless-boundary-method.md. Populate assets/serverless-boundary-ledger.example.json using assets/serverless-boundary-ledger.schema.json. For each trigger, record who can emit it, which identity executes, how tenant and actor context are derived, which destinations are reachable, and what happens on retry, duplication, delay, or dead-letter delivery.
Inspect deployment templates, resource policies, event filters, IAM bindings, environment variables, secret references, temporary storage, concurrency, egress, observability, and failure destinations. Confirm provider defaults from supplied configuration or authoritative deployment evidence rather than memory.
Report boundaries
Confirm a finding when an untrusted producer, confused service, or over-broad function identity can cause a protected effect or cross a tenant/data boundary. Separate code defects from resource-policy, event-binding, deployment, and operational gaps so ownership and remediation remain precise.
