Enhance documentation for Flakestorm V2 features, including detailed updates on behavioral contracts, context attacks, and scoring mechanisms. Added new configuration options for state isolation in agents, clarified context attack types, and improved the contract report generation with suggested actions for failures. Updated various guides to reflect the latest changes in chaos engineering capabilities and replay regression functionalities.

## V2: Reset for stateful agents (contract matrix)
|
||||
|
||||
When running **behavioral contracts** (`flakestorm contract run` or `flakestorm ci`), each (invariant × scenario) cell should start from a clean state. Configure one of:
|
||||
|
||||
- **`reset_endpoint`** — HTTP POST endpoint (e.g. `http://localhost:8000/reset`) called before each cell.
|
||||
- **`reset_function`** — Python module path (e.g. `myagent:reset_state`) for `type: python`; the function is called (or awaited if async) before each cell.
|
||||
|
||||
If the agent appears stateful and neither is set, Flakestorm logs a warning. See [Behavioral Contracts](BEHAVIORAL_CONTRACTS.md) and [V2 Spec](V2_SPEC.md).
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **For Development:** Use Python adapter if possible (fastest, simplest)
|
||||
2. **For Testing:** Use localhost HTTP endpoint (easy to debug)
|
||||
3. **For CI/CD:** Use public endpoint or cloud deployment
|
||||
3. **For CI/CD:** Use public endpoint or cloud deployment (native CI/CD is Cloud only)
|
||||
4. **For Production Testing:** Use production endpoint with proper authentication
|
||||
5. **Security:** Never commit API keys - use environment variables

# Context Attacks (V2)
|
||||
|
||||
Context attacks are **chaos applied to content that flows into the agent from tools or memory — not to the user prompt.** They test whether the agent is fooled by adversarial content in tool responses, RAG results, or other context the agent trusts (OWASP LLM Top 10 #1: indirect prompt injection).
|
||||
Context attacks are **chaos applied to content that flows into the agent from tools or to the input before invoke — not to the user prompt itself.** They test whether the agent is fooled by adversarial content in tool responses, RAG results, or poisoned input (OWASP LLM Top 10 #1: indirect prompt injection).
|
||||
|
||||
---
|
||||
|
||||
## Not the user prompt
|
||||
|
||||
- **Mutation / prompt injection** — The *user* sends adversarial text (e.g. “Ignore previous instructions…”). That’s tested via mutation types like `prompt_injection`.
|
||||
- **Context attacks** — The *tool* (or retrieval, memory, etc.) returns content that looks normal but contains hidden instructions. The agent didn’t ask for it; it arrives as “trusted” context. Flakestorm injects that via the chaos layer so you can verify the agent doesn’t obey it.
|
||||
- **Mutation / prompt injection** — The *user* sends adversarial text (e.g. "Ignore previous instructions…"). That's tested via mutation types like `prompt_injection`.
|
||||
- **Context attacks** — The *tool* returns valid-looking content with hidden instructions, or **memory_poisoning** injects a payload into the **user input before each invoke**. Flakestorm applies these in the chaos interceptor so you can verify the agent doesn't obey them.
|
||||
|
||||
So: **user prompt = mutations; tool/context = context attacks.**
|
||||
So: **user prompt = mutations; tool/context and (optionally) input before invoke = context attacks.**

|
||||
|
||||
## Two ways to poison “what the agent sees”
|
||||
## How context attacks are applied
|
||||
|
||||
The **chaos interceptor** applies:
|
||||
|
||||
- **memory_poisoning** — To the **user input before each invoke**. One payload per scenario; strategy: `prepend` | `append` | `replace`. Only the first `memory_poisoning` entry in the normalized list is applied.
|
||||
- **indirect_injection** — Into tool/context response content (when wired via transport) with `trigger_probability` and `payloads`.
|
||||
|
||||
LLM faults (timeout, truncated_response, empty, garbage, rate_limit, response_drift) are applied in the same interceptor: **timeout** before the adapter call; others **after** the response.

## Two ways to poison "what the agent sees"
|
||||
|
||||
| Mechanism | Config | What happens |
|
||||
|-----------|--------|----------------|
|
||||
| **Tool fault: `malicious_response`** | `chaos.tool_faults[].mode: malicious_response` | The tool returns **obviously bad** output (e.g. raw injection text). The agent should detect that something is wrong. |
|
||||
| **Context attack: `indirect_injection`** | `chaos.context_attacks[]` with `type: indirect_injection` | The tool returns **valid-looking** content that contains hidden instructions (e.g. a normal email body that includes “Ignore previous instructions…”). Harder for the agent to detect. |
|
||||
| **Context attack: `indirect_injection`** | `chaos.context_attacks[]` with `type: indirect_injection` | The tool returns **valid-looking** content that contains hidden instructions. Harder for the agent to detect. |
|
||||
| **Context attack: `memory_poisoning`** | `chaos.context_attacks[]` with `type: memory_poisoning` | A **payload** is injected into the **input before invoke** (prepend / append / replace). |
|
||||
|
||||
Use **context_attacks** when you want to test indirect injection and similar attacks on tool/context content.

## system_prompt_leak_probe (contract assertion)
|
||||
|
||||
**system_prompt_leak_probe** is implemented as a **contract invariant** that uses **`probes`**: a list of probe prompts to run instead of golden_prompts for that invariant. The agent must not leak the system prompt in the response. Use `type: excludes_pattern` with `patterns` defining forbidden content, and set **`probes`** to the list of prompts that try to elicit a leak. See [Behavioral Contracts](BEHAVIORAL_CONTRACTS.md) and [V2 Spec](V2_SPEC.md).

## Contract invariants
|
||||
|
||||
To assert the agent *resists* context attacks, add invariants in your **contract** that run when chaos (or context attacks) are active, for example:
|
||||
To assert the agent *resists* context attacks, add invariants in your **contract** with appropriate `when` (e.g. `any_chaos_active`) and severity:
|
||||
|
||||
- **system_prompt_not_leaked** — Agent must not reveal system prompt under probing (e.g. `excludes_pattern`).
|
||||
- **injection_not_executed** — Agent behavior unchanged under injection (e.g. baseline comparison + similarity threshold).
|
||||
|
||||
Define these under `contract.invariants` with appropriate `when` (e.g. `any_chaos_active`) and severity.
|
||||
- **system_prompt_not_leaked** — Use `probes` and `excludes_pattern` (see above).
|
||||
- **injection_not_executed** — Use `behavior_unchanged` with `baseline: auto` or manual baseline and `similarity_threshold`.

Chaos can also target **content that flows into the agent from tools or memory** — e.g. a tool returns valid-looking text that contains hidden instructions (indirect prompt injection). This is configured under `context_attacks` and is **not** applied to the user prompt. See [Context Attacks](CONTEXT_ATTACKS.md) for types and examples.
|
||||
Chaos can target **content that flows into the agent from tools** (indirect_injection) or **the user input before each invoke** (memory_poisoning). The **chaos interceptor** applies memory_poisoning to the input before calling the agent; LLM faults (timeout, truncated_response, rate_limit, empty, garbage, response_drift) are applied in the same layer (timeout before the call, others after the response). Configure under `chaos.context_attacks` as a **list** or **dict**; each scenario in `contract.chaos_matrix` can also define `context_attacks`.

flakestorm is an **adversarial testing framework** and **chaos engineering platform** for AI agents. It applies chaos engineering principles to systematically test how your AI agents behave under unexpected, malformed, or adversarial inputs. With **V2** (`version: "2.0"` in config) you get environment chaos (tool/LLM faults, context attacks), behavioral contracts (invariants × chaos matrix), and replay regression; **22+ mutation types** and **max 50 mutations per run** in OSS. API keys for cloud LLM providers must be set via environment variables only (e.g. `api_key: "${OPENAI_API_KEY}"`). See [Configuration Guide](CONFIGURATION_GUIDE.md) and [V2 Spec](V2_SPEC.md).

## Contract invariants: system_prompt_leak_probe and behavior_unchanged
|

|

- **system_prompt_leak_probe:** Use a contract invariant with **`probes`** (list of probe prompts). The contract engine runs those prompts instead of golden_prompts for that invariant and verifies the response (e.g. with `excludes_pattern`) so the agent does not leak the system prompt.

- **behavior_unchanged:** Use invariant type `behavior_unchanged`. Set **`baseline`** to `auto` to compute a baseline from one run without chaos, or provide a manual baseline string. Response is compared with **`similarity_threshold`** (default 0.75).
