From 4c1b43c5d57ace1bd4e0c3777b817268ed79d9d7 Mon Sep 17 00:00:00 2001 From: "Francisco M Humarang Jr." Date: Sun, 8 Mar 2026 20:29:48 +0800 Subject: [PATCH] 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. --- docs/API_SPECIFICATION.md | 13 ++- docs/BEHAVIORAL_CONTRACTS.md | 11 +- docs/CONFIGURATION_GUIDE.md | 48 +++++--- docs/CONNECTION_GUIDE.md | 18 ++- docs/CONTEXT_ATTACKS.md | 66 ++++++++--- docs/DEVELOPER_FAQ.md | 4 +- docs/ENVIRONMENT_CHAOS.md | 7 +- docs/IMPLEMENTATION_CHECKLIST.md | 20 ++++ docs/MODULES.md | 40 +++++-- docs/REPLAY_REGRESSION.md | 3 + docs/TEST_SCENARIOS.md | 2 + docs/USAGE_GUIDE.md | 2 +- docs/V2_SPEC.md | 11 +- src/flakestorm/cli/main.py | 105 +++++++++++++++++- src/flakestorm/core/orchestrator.py | 29 +++-- src/flakestorm/reports/contract_report.py | 127 ++++++++++++++++++++-- src/flakestorm/reports/replay_report.py | 103 ++++++++++++++++-- 17 files changed, 518 insertions(+), 91 deletions(-) diff --git a/docs/API_SPECIFICATION.md b/docs/API_SPECIFICATION.md index 7a2b8a7..43c6379 100644 --- a/docs/API_SPECIFICATION.md +++ b/docs/API_SPECIFICATION.md @@ -48,14 +48,19 @@ config = FlakeStormConfig.from_yaml(yaml_content) | Property | Type | Description | |----------|------|-------------| -| `version` | `str` | Config version | -| `agent` | `AgentConfig` | Agent connection settings | -| `model` | `ModelConfig` | LLM settings | -| `mutations` | `MutationConfig` | Mutation generation settings | +| `version` | `str` | Config version (`1.0` \| `2.0`) | +| `agent` | `AgentConfig` | Agent connection settings (includes V2 `reset_endpoint`, `reset_function`) | +| `model` | `ModelConfig` | LLM settings (V2: `api_key` env-only) | +| `mutations` | `MutationConfig` | Mutation generation (max 50/run OSS, 22+ types) | | `golden_prompts` | `list[str]` | Test prompts | | `invariants` | `list[InvariantConfig]` | Assertion rules | | `output` | `OutputConfig` | Report settings | | `advanced` | `AdvancedConfig` | Advanced options | +| **V2** `chaos` | `ChaosConfig \| None` | Tool/LLM faults and context_attacks (list or dict) | +| **V2** `contract` | `ContractConfig \| None` | Behavioral contract and chaos_matrix (scenarios may include context_attacks) | +| **V2** `chaos_matrix` | `list[ChaosScenarioConfig] \| None` | Top-level chaos scenarios when not using contract.chaos_matrix | +| **V2** `replays` | `ReplayConfig \| None` | Replay sessions (file or inline) and LangSmith sources | +| **V2** `scoring` | `ScoringConfig \| None` | Weights for mutation, chaos, contract, replay (must sum to 1.0) | --- diff --git a/docs/BEHAVIORAL_CONTRACTS.md b/docs/BEHAVIORAL_CONTRACTS.md index a480049..82f8fa2 100644 --- a/docs/BEHAVIORAL_CONTRACTS.md +++ b/docs/BEHAVIORAL_CONTRACTS.md @@ -63,16 +63,19 @@ contract: | Field | Required | Description | |-------|----------|-------------| | `id` | Yes | Unique identifier for this invariant. | -| `type` | Yes | Same as run invariants: `contains`, `regex`, `latency`, `valid_json`, `similarity`, `excludes_pii`, `refusal_check`, `completes`, `output_not_empty`, `contains_any`, etc. | +| `type` | Yes | Same as run invariants: `contains`, `regex`, `latency`, `valid_json`, `similarity`, `excludes_pii`, `refusal_check`, `completes`, `output_not_empty`, `contains_any`, `excludes_pattern`, `behavior_unchanged`, etc. | | `severity` | No | `critical` \| `high` \| `medium` \| `low` (default `medium`).
