What it does
Test Authentication Lifecycle is an agent skill from cyberful/cyberful. Coordinate testing of authentication and authenticator state across registration, login, MFA, recovery, linking, federation, device trust, reauthentication, suspension, and revocation. Use for cross-ceremony lifecycle coverage; use a narrower identity specialist for one ceremony or enforcement mechanism.
Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `agents/openai.yaml`, `references/field-heuristics.md` and `references/lifecycle-checks.md`).
It sits in Backend & APIs, covering Authentication. 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
- Cross-ceremony lifecycle coverage
- Use a narrower identity specialist for one ceremony
- Enforcement mechanism
Example prompts
- “/test-authentication-lifecycle”
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
Test Authentication Lifecycle loads about 709 tokens when it runs, and up to ~2.6k if it reads all its reference files. Until then it costs about 84 tokens; SKILL.md has 204 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.

Test the Authentication Lifecycle
Own the cross-ceremony state model; route each mechanism to the narrowest specialist.
Build the ceremony ledger
Inventory registration, invitation, login, passkeys, OTP, push, backup codes, recovery, identifier change, account linking, SSO bootstrap, device enrollment, remembered devices, step-up, support override, impersonation, rotation, suspension, deletion, and deprovisioning.
For every ceremony record:
claimed identity | evidence | channel | freshness | attempts | prior state | next state | assurance | session effect | notification | audit event | revocation
Use references/lifecycle-checks.md to find missing states. Use references/field-heuristics.md only for seams between ceremonies.
Route the mechanisms
- Recovery proof, authenticator replacement, and invalidation:
test-account-recovery-assurance. - Linking, invitations, provisioning, and aliases:
test-identity-linking-provisioning. - OIDC, OAuth, SAML, and federation:
test-federated-identity. - Service and workload credentials:
test-service-workload-identity. - End-to-end identity context:
trace-identity-propagation. - Policy placement and default-deny behavior:
audit-access-policy-enforcement. - Session issuance, rotation, and revocation:
test-session-security.
Read references/mfa-recovery.md only when coordinating MFA or recovery coverage. Do not repeat specialist test steps here.
Integrate results
Compare expected-success and expected-denial transitions across web, mobile, API, support, and federated channels. Reconcile whether old credentials, challenges, sessions, devices, links, and recovery factors survive each state transition. Confirm only when an unauthorized actor can create, assume, recover, link, retain, or elevate an identity without the required evidence; name the ceremony, state transition, factor bypassed, session effect, and revocation result.
