Agent Observatory — Mission Control Development Tracker

Overview

The Agent Observatory is a Streamlit-based observability and exploration application for the KDD Data Agent Creative Track. It transforms agent reasoning into a professional, judge-facing "Mission Control" experience with dark theme, executive narratives, and actionable insights — all without modifying core agent logic.

Repository: src/data_agent_baseline/observatory/
Launch: streamlit run src/data_agent_baseline/observatory/app.py
Artifacts: /data3/dataFAIR/kdd-dev/public/artifacts/runs/ (with fallback to artifacts/runs/)

Current Task Intelligence IA (Phase 19C-H, 2026-07-01)

• Task Intelligence now uses five primary judge-oriented sections:
  • Summary
  • Reasoning & Replay
  • Evidence
  • Review & Reliability
  • Raw Trace
• Reasoning & Replay is grouped via nested subsections:
  • Reasoning Flow (existing DAG renderer)
  • Guided Step Inspector (existing Replay renderer)
• Review & Reliability is grouped via nested subsections:
  • Review Signals
  • Trust Calibration
  • Diagnosis & Verification
• Evidence continues to render Evidence & Provenance content, and Raw Trace remains the final advanced forensic section.
• Task Health Strip remains above the five primary sections.
• Grouped subsection failures are isolated so one failing renderer does not break sibling subsections.
• No runtime, evaluation, HITL execution-control, runner, or artifact-schema behavior changes were introduced by this IA consolidation.

Phase Completion Log

Phase 1: Foundation & Core Loaders ✅

Status: Complete
Date: 2026-06-16
Execution Time: ~1 hour

Files Created:

• ✅ src/data_agent_baseline/observatory/__init__.py — Package initialization (exports RunDiscovery, TaskDiscovery, ArtifactFinder, ArtifactLoader, RunLoader, etc.)
• ✅ src/data_agent_baseline/observatory/data_models.py — Normalized dataclasses (TraceEvent, NormalizedTask, NormalizedRun, MetricNormalizer, NormalizePhases)
• ✅ src/data_agent_baseline/observatory/loaders.py — Artifact discovery and loading (RunDiscovery, TaskDiscovery, ArtifactFinder, ArtifactLoader, RunLoader)
• ✅ src/data_agent_baseline/observatory/trace_parser.py — Trace parsing helpers (parse_trace_events, extract_question, extract_final_answer, and utilities)

Verification Results:

• ✅ All imports successful
• ✅ RunDiscovery: finds 175 runs in /data3/dataFAIR/kdd-dev/public/artifacts/runs/
• ✅ TaskDiscovery: finds 50 tasks in sample run 20260616T055650Z
• ✅ ArtifactLoader: successfully loads comprehensive_evaluation.csv, summary.json, trace.json
• ✅ TraceEventParser: parses 14 trace events, identifies 9 unique tools used
• ✅ MetricNormalizer: correctly maps old field names (execution_success) to new (task_success)

Key Decisions Implemented:

1. Lazy loading: Runs listed without reading traces (startup < 1s, O(n) folder scan)
2. Default path: /data3/dataFAIR/kdd-dev/public/artifacts/runs/ with fallback to artifacts/runs
3. Graceful degradation: All loaders return None/empty on missing files
4. Backward compatibility: Support both old and new metric column names
5. Defensive parsing: Handle multiple trace schema variants (steps, events, messages, etc.)

Testing Status: Ready for unit tests in Phase 12

• ✅ Task discovery: Lists 50 tasks per run with dropdown
• ✅ Session state: Caches run/task to avoid re-loading
• ✅ Tab structure: All 8 tabs present with placeholder content

Key Features:

1. Interactive run selection — Dropdown with 175 runs (most recent first)
2. Task selection — Dropdown with available tasks for selected run
3. Artifact path configuration — Text input with default path, fallback logic
4. Run info panel — Shows task count, timestamp, metadata
5. Task info panel — Shows status, success metric, score
6. Artifact status indicator — Checkmarks for trace.json, CSV, replay, provenance
7. Session caching — Lazy-load on selection; no repeated file reads
8. Tab placeholder structure — Phases 3-10 ready for implementation

Design Decisions:

• Use st.session_state for persistent selections within app session (not page reloads)
• Lazy-load: Discovery on startup (fast), run/task load on selection
• Expanders for run/task info to keep sidebar clean
• @st.cache_data not needed for loaders (small overhead)

Performance:

• Sidebar rendered: < 500ms

Phase 17: Executive Summary Enhancement ✅

Status: Complete
Date: 2026-06-17
Execution Time: ~2 hours

Objective: Incorporate CLI exec-report narrative structure into Streamlit Mission Summary

Files Modified:

• ✅ src/data_agent_baseline/observatory/overview_page.py — Added comprehensive executive narrative

New Helper Functions:

1. _extract_refinement_attempts(task) — Extracts execution/refinement cycles from trace events
2. _extract_decision_reasoning(task) — Extracts strategy, target output, expected results
3. _extract_deliverables(task, run) — Extracts results file path and output columns

New Executive Summary Section:

Placed at top of Mission Summary (before Question/Answer cards), includes 4 professional blocks:

A. Mission Overview Block

• Execution Status (with colored badge)
• Completion Time (formatted as "Xm Ys")
• Refinement Cycles (attempt count)
• Confidence Level (derived from refinement count):
  • 1 attempt → "High confidence — succeeded on first attempt"
  • 2-3 attempts → "Moderate confidence — N refinement cycles"
  • 4+ attempts → "Multiple iterations — N refinement cycles"

B. Decision Reasoning Block (blue gradient card)

• 💡 Strategy: Extracted from plan reasoning (up to 500 chars)
• 📋 Target Output: Column names from output_columns
• 📊 Expected Result: Row count from expected_row_count
• Graceful fallback to question if no reasoning found

C. Execution & Refinement Timeline

• Professional table showing attempts
• Columns: Attempt #, Status (Pass/Refine), Insight / Action Taken
• Extracts insights from trace events:
  • Feedback messages
  • Error descriptions
  • Verification results
  • Success confirmations
• Color-coded: Green (✓ Pass), Yellow (⟳ Refine)
• Shows "No refinement cycles detected" if none found

D. Deliverables Block (green gradient card)

• 📁 Results File: Full path to prediction.csv
• 📊 Output Columns: Comma-separated column list
• ⚠️ Status: Warning if task failed
• 📁 Output Directory: Shown if no prediction file

Terminology Updates in KPI Cards:

• "OUTCOME" → "EXECUTION STATUS"
• "TRUST" → "VERIFICATION"
• "TASK SCORE" (unchanged)
• "RUNTIME" (unchanged)

Visual Design:

• Mission Overview: Clean table with aligned labels
• Decision Reasoning: Blue gradient background, left border accent
• Timeline: Professional table with borders and hover effects
• Deliverables: Green gradient background, left border accent
• All cards use dark theme with proper spacing

Data Extraction Strategy:

1. Refinement Attempts: Parse trace_events for execute/critic/verify/refine events
2. Decision Reasoning: Extract from raw_trace → plan_reasoning, output_columns, expected_row_count
3. Deliverables: Construct path from run.base_path + task_id, extract columns from trace

Graceful Degradation:

• Missing reasoning → Shows "No refinement cycles detected"
• Missing strategy → Falls back to question text
• Missing deliverables → Shows output directory instead
• All sections handle None/empty values gracefully

Page Structure After Enhancement:

1. Compact Header (status pills + metrics)
2. Executive Summary ← NEW comprehensive 4-block section
3. Question Card
4. Answer Card
5. KPI Cards (with updated labels)
6. Execution Story
7. Debug sections (collapsed)

Benefits:

• Judge-Facing: Immediately explains what happened in <10 seconds
• Narrative Structure: Mirrors CLI exec-report (executive_reporter.py)
• Comprehensive: Covers reasoning, execution, and deliverables
• Professional: Clean cards, gradients, proper typography
• Production Ready: No raw JSON, all details in expanders

Verification Results:

• ✅ All helper functions import successfully
• ✅ Executive Summary renders properly
• ✅ Timeline extracts attempts from trace events
• ✅ Reasoning block shows strategy when available
• ✅ Deliverables block shows file paths
• ✅ No errors with missing data (graceful degradation works)
• ✅ Professional appearance maintained

Future Enhancements

Planned:

• Light theme variant for daytime viewing
• Export report as PDF
• Batch comparison view (multiple tasks side-by-side)
• Historical trend analysis across runs
• Advanced filtering (by difficulty, status, score range)
• Customizable KPI thresholds
• Integration with evaluation pipeline

Under Consideration:

• Real-time execution monitoring (WebSocket)
• Task execution directly from Observatory
• Annotation tools for failure analysis
• Collaboration features (comments, tags)
• Performance profiling (token/time per operation)

---

Troubleshooting

Issue: "No runs found"

• Solution: Check artifact path in Advanced Configuration
• Default: /data3/dataFAIR/kdd-dev/public/artifacts/runs/
• Fallback: artifacts/runs

Issue: "Unable to load run data"

• Solution: Verify run folder exists and contains summary.json and/or comprehensive_evaluation.csv
• Check: File permissions

Issue: "Unable to load task data"

• Solution: Verify task folder exists (e.g., task_11/) and contains trace.json
• Note: App works even if some files are missing (graceful degradation)

Issue: Broken icon text visible

• Solution: Hard refresh browser (Ctrl+F5 or Cmd+Shift+R)
• Note: CSS should hide all Material icon leakage

Issue: App loads slowly

• Solution: First load takes 1-2s for discovery; subsequent loads are cached
• Note: Large runs (>100 tasks) may take longer to parse traces

Known Issues & Design Notes

1. Question extraction: Sample task trace doesn't have top-level "question" field — will implement fallback extraction from trace structure
2. Specialist data: Early runs may lack full AAT data; high-level DAG will always work
3. Confidence model: Will use hybrid approach (existing data + derived components)
4. Graph rendering: Fallback to table if PyVis/Plotly unavailable
5. Caching: Phase 2 will use lightweight Streamlit @st.cache_data for run list

---

Next Immediate Steps

1. ✅ COMPLETE: Mission Control UI/UX transformation (Phase 15)
2. ✅ COMPLETE: Blank page fix and launch utilities (Phase 16)
3. ✅ COMPLETE: Live Trace Flow UX refinements (Phase 16b — ongoing iteration)
4. Optional: Enhance other tab pages (DAG, Replay, Provenance, etc.) with Mission Control styling
5. Optional: Add difficulty classification logic based on task metrics
6. Optional: Add export functionality for executive summaries
7. Future: Add comparison view for multiple runs side-by-side

Current State

Version: 0.4.0 — Live Trace Flow Edition
Status: Production-ready for judge evaluation, executive review, and live run inspection
All Phases: ✅ Complete (17/17 + Phase 16b refinements)
Launch: streamlit run src/data_agent_baseline/observatory/app.py
Troubleshooting: See OBSERVATORY_TROUBLESHOOTING.md

What's New in v0.4.0

• Phase 19 navigation consolidation: primary navigation now has four pages:
  • Run Launcher
  • Run Intelligence (with Run Health Summary + Trajectory Intelligence)
  • Task Intelligence
  • Demo / Future Proof
• Run Intelligence page structure:
  • Run Health Summary: compact KPI cards (Harness Health, Execution Success Rate, Failed Tasks, Mean Score and related run KPIs) with inline tooltips
  • Verification Summary: compact verification cards with per-metric tooltip formulas and source-column provenance
  • Reliability Diagnostics:
    • Root Cause Distribution compact panel with severity metadata and task previews
    • Root-cause summary cards (failed/low-score tasks, diagnosed root causes, top root cause, no-root-cause count)
    • Root-cause task inspector (deep link only to Task Intelligence)
    • Raw root-cause table/task-id views moved behind toggles
  • Trajectory Intelligence: Full-run trajectory analysis including:
    • Trajectory KPI Snapshot: total trajectories/tasks, dominant patterns, mean length/branching/critic loops, success rates, recovery rates, replay artifact count
    • Dominant Trajectory Patterns: summary interpretation (Clean, Retry, Replan, Complex Recovery)
    • Phase Timeline & Token Economics: per-phase breakdown with time%, token counts, tool calls/failures, confidence
    • Recovery / Self-Correction Flow: first-try/recovery rates, retries/replans by source
      • Coordinator Decision Visibility + Trajectory Health Labels rendered as compact observability panels
      • Trajectory Examples preserved as visual insight section
  • Recommended Tasks to Inspect:
    • unified curated task selector across Representative Tasks + Trajectory Examples
    • single deep-link action: Open in Task Intelligence
    • no Replay/DAG/Failure Analysis buttons in Run Intelligence
  • Detailed tables (Summary/Detailed/Research modes): Task Outcomes, Failure Distribution, Resource Usage, Validation Diagnostics, Artifact Completeness
  • Guided Rerun Cohort Analysis: shown in Summary view when guided reruns exist
• Task Intelligence shell: Mission Summary is no longer top-level; task-level views are grouped into five internal sections (Summary, Reasoning & Replay, Evidence, Review & Reliability, Raw Trace).
• Demo / Future Proof shell: Checkpoint, rerun planning/comparison, evidence pack, and demo workflows are grouped in one page.
• Fallback stability preserved: Live Trace Flow and Guided Live Trace Flow remain available directly from the sidebar View selector, with no renderer internals refactored.
• Primary-page cleanup: Advanced / Fallback Views informational text was removed from the Run Intelligence app-shell area and moved to Task Intelligence guidance text.
• Runtime behavior unchanged: no execution, evaluation, HITL runtime, or artifact schema changes in this phase.
• Phase 20 out of scope: no natural-language artifact Q&A changes in this phase.
• Live Trace Flow tab (⚡): Start runs, attach to existing runs, inspect tasks live during execution
• Run Intelligence no-eval fallback: when evaluation artifacts are missing, Run Intelligence renders read-only execution telemetry sections plus explicit eval-v2 guidance (no in-page execution trigger)
• Conditional Run Intelligence controls: View level selector appears only when evaluation artifacts exist
• Launcher-to-Intelligence handoff: terminal runs expose a direct "Open Run Intelligence" action in Run Launcher
• Clickable step buttons in Live / Replay: each step is a button; clicking syncs Step Output Inspector
• 50:50 split between Live / Replay and Step Output Inspector
• Click-driven inspector: no dropdown; governed solely by Live/Replay button click; refreshes only on task start/end transitions
• Condensed run status object-style line with icons: Run Status | ▶️ Running | ✅ Completed | ❌ Failed | ⏳ Queued
• Running-task auto-selection: task selector auto-follows the currently running task; user can override
• Step button two-part display: button line + caption (<story_group> | Action - <Thought>)
• Key findings untruncated in Evidence Table
• 500 ms poll interval for live updates (previously 1 s)
• Agent Reasoning Overlay surfaced above Status Commentary
• Auto-refresh always-on (no user toggle required)

---

Implementation Notes

• All parsing is defensive: handles missing/variant schemas gracefully
• No modifications to core agent reasoning logic; Observatory actions remain artifact-oriented (run launch, run attachment, and explicit eval-v2 trigger)
• Standalone under src/data_agent_baseline/observatory/ (no coupling to existing visualization code)
• Load-on-demand architecture: scales to 150+ runs without upfront cost
• Session-based state in Streamlit (no persistent storage needed)
• Mission Control styling is pure CSS — no JavaScript dependencies
• All components use HTML/CSS injection via st.markdown(unsafe_allow_html=True)
• Backward compatible with all existing loaders and builders
