Organization

authenticated-session-acquisition

Acquire an authenticated session THROUGH MFA/OTP on an in-scope target and emit a reusable session artifact (Playwright storageState + Bearer) so executors can test the post-auth attack surface. Use when the highest-value authenticated classes (BOLA/IDOR/mass-assignment/injection on the real data APIs) are blocked because login is gated by SMS-OTP or TOTP MFA. Distinct from the authentication skill (which ATTACKS auth); this one legitimately authenticates and hands the session to the rest of the engagement.

  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 1 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by transilienceai on GitHub. Read the source before you install it.

Installation

Install the Authenticated Session Acquisition AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/transilienceai/communitytools/tree/main/skills/authenticated-session-acquisition
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/transilienceai/communitytools.git /tmp/communitytools
mkdir -p .claude/skills
cp -r /tmp/communitytools/skills/authenticated-session-acquisition .claude/skills/authenticated-session-acquisition
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Authenticated Session Acquisition in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Authenticated Session Acquisition on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Authenticated Session Acquisition is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Authenticated Session Acquisition

On financial and multi-tenant targets the login is gated by SMS OTP / TOTP MFA that an autonomous run cannot satisfy, so the post-auth surface (BOLA/IDOR/mass-assignment/injection on the real data APIs, session handling, API pivots) silently collapses to pre-auth findings only. This skill's job is narrow and concrete: get one legitimate authenticated session and hand it to the executors as a reusable artifact. It does not attack the auth mechanism — see authentication for that.

The artifact contract (how the session reaches executors)

Emit both, into the engagement's OUTPUT_DIR, referenced BY NAME (never inline secrets — credential-loading.md):

  • OUTPUT_DIR/<asset>/session/storageState.json — the Playwright storage state (cookies + localStorage) for browser-driven post-auth testing.
  • OUTPUT_DIR/<asset>/session/bearer.txt — the raw access/ID token (+ its expires_at) for direct API replay.

Executors consume these exactly like any env-loaded secret: the scope file's creds_env names the realm, and the session path is passed as a file reference, so no token is ever written into a prompt, experiments.md, or attack-chain.md. Re-run this skill when the token expires (record expires_at; refresh rather than re-login where a refresh token exists).

Modes (pick by what the client can provide)

ModeWhenHow
TOTP-from-seedThe client shared the TOTP secret (Base32 seed) for a test accountGenerate the current code deterministically with tools/totp_now.py <BASE32_SEED>, submit it in the login flow. Fully autonomous, repeatable.
Explicit-OTPThe operator can read a one-time code (SMS/email/authenticator) at run timeDrive login to the OTP prompt, the operator supplies the code once, continue.
Human-in-the-loop resumeOTP arrives out-of-band and the run must pausePersist the pre-OTP browser context, pause; the operator completes the challenge; resume and capture storageState.

Provider recipes

Detailed per-IdP flows are in reference/session-acquisition.md: Auth0, Okta, Amazon Cognito (SRP auth + the UNSIGNED unauthenticated-posture check), and Descope. Each recipe ends by exporting storageState.json + bearer.txt in the contract above.

When a session cannot be acquired — defer honestly, do not fake

If no test account / OTP seed is available and no OTP can be relayed, the realm's post-auth surface is untestable through no fault of the tester. Record it honestly instead of a fabricated NA or a silent miss:

  1. File a client-input request at reports/client-input-requests/CIR-NNN.md naming exactly what's needed ("needs test account / OTP seed / allowlist for <realm>").
  2. Set a realm-level BLOCKED_REASON in attack-chain.md.
  3. Mark that realm's post-auth coverage cells status:"deferred" in coverage.json, each carrying deferral_reason + client_input_request (the CIR path) — see coverage-matrix.md. The deterministic gate then discloses the deferred surface in the report rather than hiding it, and only the parent orchestrator (via coverage_gate.py --accept-deferrals) may finalize a substantiated-deferred engagement. A scope that is entirely auth-gated never completes.

The preflight cred-reach probe (preflight-checklist.md, Phase-1 gate) is what triggers this path: present creds are not working creds; verify reachability per realm before spawning post-auth executors.

Workflow

  1. Read the scope: which realms/tenants are in creds_env, which assets are behind them, roe.reversible_writes for the test tenant.
  2. Identify the IdP (login redirect host / /.well-known/openid-configuration / SDK bundle) → pick the recipe.
  3. Acquire the session in the appropriate mode → write storageState.json + bearer.txt.
  4. Verify: one minimal authenticated request returns an authorized response (not 401/403/login-redirect).
  5. Hand the artifact paths to the post-auth executor batch; on failure, run the defer path above.

Anti-Patterns

  • Do not paste tokens, seeds, or cookies into prompts, experiments.md, attack-chain.md, or any tools/*.md — reference the artifact file by path only.
  • Do not brute-force or bypass the OTP/MFA challenge here — that is an authentication finding, not session acquisition.
  • Do not mark an MFA-blocked cell covered/NA — mark it deferred with a filed CIR so the gate discloses it.
  • Do not test outside the authenticated tenant you were given, and honor roe.reversible_writes (create-then-delete only in your own test tenant).

Frequently asked questions

What does the Authenticated Session Acquisition AI skill do?

Acquire an authenticated session THROUGH MFA/OTP on an in-scope target and emit a reusable session artifact (Playwright storageState + Bearer) so executors can test the post-auth attack surface. Use when the highest-value authenticated classes (BOLA/IDOR/mass-assignment/injection on the real data APIs) are blocked because login is gated by SMS-OTP or TOTP MFA. Distinct from the authentication skill (which ATTACKS auth); this one legitimately authenticates and hands the session to the rest of the engagement.

Why use Authenticated Session Acquisition on TypingMind?

Because you install it once and use it with any model. Authenticated Session Acquisition is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Authenticated Session Acquisition in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/transilienceai/communitytools/tree/main/skills/authenticated-session-acquisition. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Authenticated Session Acquisition?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Authenticated Session Acquisition?

As many as you like. As long as a model supports skills, you can use Authenticated Session Acquisition with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Authenticated Session Acquisition AI skill free?

Yes. It is published on GitHub by transilienceai under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
