      "content": "Let's dive into your problem description. I will look for potential gaps and ambiguities that could lead to issues in implementation or operation.\n\n1. **Ambiguity in Rule Prioritization:**\n   Your description states \"rules are evaluated as first-match-wins.\" This raises a concern about priority conflicts among rules. What happens if two rules could potentially match the same tool call due to overlapping conditions? How are ties broken, and which component decides the priority order? It’s crucial to define a clear mechanism for rule overlap to prevent unintended execution of commands.\n\n   **Conflict-Resolution Probe:** If there is a disagreement between two rules about which should apply, how is it resolved? Is there a log of which rule was applied and the rationale?\n\n   **Storage Obligation Probe:** Where do you store the precedence or priority order of these rules, and how is the system kept up-to-date with any changes in these rules?\n\n2. **User Account Specificity:**\n   The issue highlighted relates to the AI agent potentially using the wrong GitHub account. There is a need to understand how user accounts are assigned and verified for operations. What guarantees does the system have that the AI agent will choose the correct account beyond checking at execution time? Is authentication tied to specific commands, and how is this enforced?\n\n   **Storage Obligation Probe:** Which storage system tracks GitHub account assignments to specific tool calls, and what fields are used to ensure it is accurate and up-to-date? Is there sensitive data involved, like OAuth tokens, that need encryption or other protections?\n\n   Addressing these challenges helps prevent potential operational errors where critical conditions may be missed, or unintended actions are performed due to inadequate rule specification or unexpected account mismatches.\n\n```json\n{\n  \"ready_to_proceed\": false,\n  \"problem_model_update\": {\n    \"assumptions\": [\n      \"Rules have no implicit priorities when overlapping conditions occur.\",\n      \"AI agent account usage is dynamically validated against predefined rules.\"\n    ],\n    \"failure_modes\": [\n      {\n        \"description\": \"Rule overlap leading to unpredictable tool call determination.\",\n        \"severity\": \"high\",\n        \"historical\": \"unknown\"\n      },\n      {\n        \"description\": \"Incorrect AI agent GitHub account usage due to validation or assignment errors.\",\n        \"severity\": \"medium\",\n        \"historical\": \"some incidents\"\n      }\n    ]\n  }\n}\n```",

  "prompt_md": "## System Context\nThis system provides deterministic policy enforcement for AI agent tool calls. Every proposed tool call from an AI agent is evaluated against a set of predefined rules by a Rust single binary referred to as `signet-eval`, ensuring compliance before execution. The primary users of this system are AI agents.\n\n## Consequence Map\n- **High Severity**: An AI agent uses the wrong GitHub account for remote operations, which can lead to unauthorized actions, incorrect deploys, and failed pushes.\n- **Medium Severity**: Overlapping rules lead to unpredictable tool call determinations, causing potential disruptions in AI agent workflows.\n- **Low Severity**: Incorrect validation of AI agent GitHub account usage, leading to minor operational inefficiencies.\n\n## Failure Archaeology\n- **What's Gone Wrong**: The system has encountered issues where the AI agents make tool calls with incorrect GitHub accounts.\n- **What Was Tried**: Adjustments in rule prioritization were attempted but found inadequate due to lack of implicit prioritization in rules.\n- **What Was Learned**: Deterministic evaluation without implicit rule priorities can lead to unpredictability if rules overlap. Hierarchical or priority-driven rules may need consideration.\n\n## Dependency Landscape\n- **Touches**: None explicitly mentioned beyond intrinsic system calls and AI agent interfaces.\n- **Touched By**: AI agents proposing tool calls for validation and execution.\n\n## Boundary Conditions\n- **Scope**: Enforcement mechanism for tool calls by AI agents.\n- **Non-Goals**: It does not include dynamic rule updates or non-deterministic validations.\n- **Constraints**: Rules are evaluated strictly on a first-match-wins basis.\n\n## Success Shape\n- The primary quality is a deterministic and predictable enforcement process for AI agent tool calls.\n- Flexibility in rule application without arbitrary implementations.\n- Seamless integration within AI agent workflows.\n\n## Done When\n- An AI agent tool call consistently passes through `signet-eval` and either executes as intended or is correctly blocked based on current rules.\n- No unauthorized GitHub account usage occurs.\n- Rule conflicts result in predictable resolutions or reported errors.\n\n## Trust and Authority Model\nThe system operates with a default trust floor of 0.10 and an authority override threshold of 0.40, ensuring a baseline of trust but requiring higher confidence to override determinations. Data classified as PII, FINANCIAL, AUTH, and COMPLIANCE have strict taint protections. Human interventions happen for FINANCIAL, AUTH, and COMPLIANCE tiers and low trust authorizations.\n\n## Component Topology\n`signet-eval` is the primary component, acting as a validator service. It receives tool call proposals through standard inputs, applies the rule engine's deterministic logic, and outputs a decision, either allowing or denying execution. Data interactions are internal, focused on rule evaluation based on agent-provided details.",
