| name | pattern-detect |
| description | Detect recurring patterns using the Agent Monitor's workflow intelligence — toolFlow transitions (tool A → B frequency matrices), recurring workflow patterns, agent co-occurrence pairs, model delegation habits, error propagation paths by agent depth, and compaction triggers. Use to discover habitual usage patterns and anti-patterns.

Pattern Detect
Identify recurring patterns using the Agent Monitor's workflow intelligence engine.
Input
The user provides: $ARGUMENTS
Options: "all", "tools", "errors", "workflows", "last N sessions".
Data Sources
| Endpoint | Returns |
|---|
GET /api/sessions?limit=200 | Session list with status, model, cwd, metadata |
GET /api/analytics | tool_usage top 20, event_types, agent_types |
GET /api/workflows/{sessionId} | 11 datasets per session (see below) |
Workflow datasets used for pattern detection
| Dataset | Pattern insight |
|---|
toolFlow | Tool transition matrix: tool A → tool B with counts — reveals sequential habits |
patterns | Detected workflow patterns: recurring sequences with frequency scores |
cooccurrence | Agent co-occurrence: which agents frequently run together |
modelDelegation | Model habits: which models are chosen for which task types |
errorPropagation | Error patterns: where errors start and how they cascade by agent depth |
effectiveness | Subagent patterns: which types succeed most, avg duration per type |
compaction | Compaction triggers: what causes context overflow |
complexity | Complexity patterns: session complexity scores over time |
Pattern Categories
1. Tool Chain Patterns (from toolFlow)
- Most common sequences: Top 10 tool transitions (e.g., Read → Edit: 145 times)
- Starter tools: First tool used in sessions (indicates task type)
- Finisher tools: Last tool before Stop event
- Anti-patterns: Tool → same Tool repeated (retries/failures)
- Co-occurrence: Tools that always appear together in sessions
2. Workflow Patterns (from patterns)
- Named patterns: Workflow sequences the API has detected with frequency
- Session archetypes: Common session shapes (short edit, long debug, subagent-heavy)
- Project-specific: Patterns that appear in specific working directories
3. Error Patterns (from errorPropagation + event_types)
- Error origins: Which agent depth level produces most errors
- Cascade patterns: Errors that trigger chains of follow-up errors
- APIError frequency: quota hits, rate_limit, overloaded — by time of day
- Recovery patterns: How errors are typically resolved (tool retry vs agent switch)
4. Agent Patterns (from cooccurrence + effectiveness)
- Agent pairs: Which agents are spawned together frequently
- Delegation patterns: Main agent → subagent task delegation habits
- Success by type: Which subagent types (task/explore/code-review) work best for which tasks
5. Temporal Patterns (from session timestamps + daily_sessions)
- Peak hours: When sessions cluster
- Duration patterns: Short vs long session distribution
- Day-of-week trends: Productive days vs quiet days
Output
Pattern Report with top 10 patterns ranked by frequency × impact:
- Pattern name and description
- Frequency (occurrences across analyzed sessions)
- Impact: positive (reinforce), negative (eliminate), or neutral (observe)
- Actionable recommendation for each
