Runtime Validation Hooks Documentation## OverviewTerraphim AI implements a **two-stage runtime validation system** that provides safety and knowledge-graph enhancement for AI-assisted development workflows. This system operates through pre/post hooks around LLM generation and tool execution.## Two-Stage Hook Flow### Stage 1: Guard Stage (Security & Bypass Protection)**Purpose**: Prevent dangerous operations and enforce safety invariants before any processing occurs.**Location**: `~/.claude/hooks/pre_tool_use.sh`**Implementation**:```bash#!/bin/bash# Extract command from JSON inputCOMMAND=$(echo "$1" | jq -r '.tool_input.command // empty')# Strip quoted strings to avoid false positivesCLEAN_COMMAND=$(echo "$COMMAND" | sed 's/"[^"]*"//g')# Check for dangerous bypass flagsif [[ "$CLEAN_COMMAND" =~ (--no-verify|-n)(?=.*\bgit\s+(commit|push)) ]]; then # Return deny decision echo '{"decision": "deny", "reason": "Git bypass flags detected"}' exit 0fi# Continue to replacement stagecd ~/.config/terraphimterraphim-agent hook "$1"```**Guard Actions**:- **Block**: `--no-verify` or `-n` flags in `git commit/push` commands- **Allow**: All other commands proceed to replacement stage- **Log**: All guard decisions with reasons### Stage 2: Replacement Stage (Knowledge Graph Enhancement)**Purpose**: Replace text using knowledge graph patterns and connectivity validation.**Location**: `terraphim-agent hook` command in Terraphim agent**Implementation**:```rust// terraphim_agent/src/commands/hook.rspub async fn execute_hook( input: HookInput, agent: &TerraphimAgent,) -> Result { // Apply knowledge graph replacements let enhanced_text = agent .rolegraph .apply_replacements(&input.text)?; // Validate connectivity agent .automata .validate_connectivity(&enhanced_text)?; Ok(HookOutput { modified_text: enhanced_text, was_modified: enhanced_text != input.text, })}```**Replacement Actions**:- **Enhance**: Apply role-based knowledge graph patterns- **Validate**: Ensure semantic connectivity and coherence- **Transform**: Use thesaurus and autocomplete for consistency## Runtime LLM/Tool Hooks### Pre-LLM Hooks**Purpose**: Validate LLM inputs before generation.**Context**:```rustPreLlmContext { prompt: String, // Command type + description agent_id: String, // Agent identifier conversation_history: Vec, // Previous messages token_count: usize, // Estimated tokens}```**Hook Decisions**:- **Allow**: Proceed with LLM generation- **Block**: Stop with reason (security, policy, etc.)- **Modify**: Transform prompt (not recommended for LLM)- **AskUser**: Require human confirmation### Post-LLM Hooks**Purpose**: Validate and potentially modify LLM outputs.**Context**:```rustPostLlmContext { prompt: String, // Original prompt response: String, // Generated response agent_id: String, // Agent identifier token_count: usize, // Total tokens used model: String, // LLM model used}```**Hook Decisions**:- **Allow**: Return original response unchanged- **Block**: Prevent response delivery (harmful content, policy violations)- **Modify**: Transform response (formatting, style, safety fixes)- **AskUser**: Require human review before delivery### Pre-Tool Hooks**Purpose**: Validate code and commands before execution.**Context**:```rustPreToolContext { code: String, // Code to execute language: String, // Programming language agent_id: String, // Agent identifier vm_id: String, // VM execution environment metadata: HashMap, // Additional context}```**Security Validations**:- **Dangerous Patterns**: `rm -rf /`, `sudo`, `chmod 777`, etc.- **Language Restrictions**: Block execution in disallowed languages- **Resource Limits**: Validate memory, CPU, and file access- **Injection Prevention**: Command injection and shell escape detection### Post-Tool Hooks**Purpose**: Monitor and analyze execution results.**Context**:```rustPostToolContext { original_code: String, // Original code executed output: String, // Execution output exit_code: i32, // Process exit code duration_ms: u64, // Execution time agent_id: String, // Agent identifier vm_id: String, // VM identifier}```**Monitoring Actions**:- **Success/Failure Tracking**: Learn patterns of successful executions- **Performance Analysis**: Track execution times and resource usage- **Security Logging**: Record blocked or suspicious activities- **Knowledge Graph Learning**: Update successful patterns for future reference## Configuration### Runtime Validation Config**Location**: `~/.config/terraphim/runtime-validation.toml````toml[hooks]enabled = truefail_open = true # Allow execution if hooks fail (development mode)[guard]strict_mode = false # Block on any suspicion vs. specific patternslog_all_decisions = true # Log allow/block decisions[llm_hooks]enabled = truerequire_human_review = false # Only for high-stakes operations[tool_hooks]enabled = truevm_isolation = trueresource_limits = true[replacement]knowledge_graph_enhancement = trueconnectivity_validation = true```### Environment Variables```bash# Enable/disable specific hook categoriesTERRAPHIM_RUNTIME_VALIDATION_HOOKS=trueTERRAPHIM_GUARD_STAGE=trueTERRAPHIM_REPLACEMENT_STAGE=true# Hook behavior overridesTERRAPHIM_FAIL_OPEN=false # Production mode: fail closedTERRAPHIM_HOOK_TIMEOUT_MS=5000 # Hook execution timeout```## Hook Development### Creating Custom Hooks```rustuse crate::vm_execution::{hooks::*, VmExecutionError};#[derive(Debug)]pub struct SecurityHook { blocked_patterns: Vec,}#[async_trait]impl Hook for SecurityHook { fn name(&self) -> &str { "security-hook" } async fn pre_tool(&self, context: &PreToolContext) -> Result { for pattern in &self.blocked_patterns { if pattern.is_match(&context.code) { return Ok(HookDecision::Block { reason: format!("Blocked pattern: {}", pattern.as_str()), });
