Functions ¶
func InputShape ¶
InputShape produces a structural fingerprint of a tool's input. For Bash: tokenizes the command and replaces variable tokens with {VAR}. For other tools: replaces values with type tags ({STRING}, {NUMBER}, etc.).
func ScorePattern ¶
ScorePattern evaluates confidence that a pattern can be compiled deterministically. Returns a float64 in [0, 1]. Scores >= threshold route to deterministic backend.
Types ¶
type Edge ¶
type Edge struct {
From, To uint64 // node IDs
Weight int // number of times this transition observed
SessionIDs []string // which sessions contributed
}
Edge represents a transition between two nodes.
type HotPath ¶
type HotPath struct {
NodeIDs []uint64 // ordered sequence of node IDs
Frequency int // number of sessions where this exact path appears
SessionIDs []string // contributing sessions
}
HotPath represents a frequently-traversed sequence of nodes in the trace graph.
func FindHotPaths ¶
func FindHotPaths(g *TraceGraph, minFrequency, minLength, maxLength int) []HotPath
FindHotPaths finds frequently-traversed subgraphs using DFS with session intersection.
type Node ¶
type Node struct {
ToolName string // e.g. "Bash", "Read", "Edit"
InputShape map[string]string // structural fingerprint
ID uint64 // hash of (ToolName, InputShape)
}
Node represents a unique tool-call shape in the trace graph.
type Parameter ¶
type Parameter struct {
Name string // e.g. "NAMESPACE", "FILE_PATH", "ARG_1"
Position int // token position in the command
Values []string // observed concrete values across instances
}
Parameter represents a variable extracted from diffing multiple instances.
func CollectUniqueParams ¶
func CollectUniqueParams(steps []PatternStep) []Parameter
CollectUniqueParams gathers unique parameters across all steps, preserving order.
type Pattern ¶
type Pattern struct {
Steps []PatternStep
Frequency int
SessionIDs []string
}
Pattern is a fully parameterized hot path ready for compilation.
func Parameterize ¶
func Parameterize(hotPaths []HotPath, events []ingest.Event, g *TraceGraph) []Pattern
Parameterize takes hot paths and raw events, aligns instances to the node sequence, and diffs tool inputs to extract parameters.
func RoutePatterns ¶
RoutePatterns splits patterns into deterministic and LLM batches based on confidence scoring.
type PatternStep ¶
type PatternStep struct {
ToolName string
Template string // command with $PARAM placeholders
Parameters []Parameter // extracted parameters
NodeID uint64
}
PatternStep is one step in a parameterized pattern.
type Token ¶
type Token struct {
Value string // the raw token text
Literal bool // true = keep as-is in template; false = parameterizable
}
Token represents a single token from a parsed Bash command.
func TokenizeBashCommand ¶
TokenizeBashCommand splits a Bash command into tokens and classifies each as literal (structural) or variable (parameterizable).
NOTE: This uses strings.Fields for splitting, so shell quoting (e.g., "foo bar"), escape sequences, and metacharacters (|, &&, >, etc.) are not handled. Each whitespace-delimited field is treated as one token.
type TraceGraph ¶
type TraceGraph struct {
Nodes map[uint64]*Node
Edges map[uint64]map[uint64]*Edge // adjacency list: from -> to -> edge
}
TraceGraph is a directed graph of tool-call sequences.
func BuildGraph ¶
func BuildGraph(events []ingest.Event) *TraceGraph
BuildGraph constructs a TraceGraph from a flat list of events. Events are grouped by session and sorted by timestamp within each session. Only post_tool_use events contribute nodes and edges.
