2026 Hackathon Submission: TRCAA
Project: TRCAA (Troubleshooting and RCA Assistant)
Feature: Autonomous AI-Powered Incident Triage with Shell Command Execution
Developer: Shaun Arman (VFK387)
ADO Work Item: #727547
Problem to Solve
An alert fires, engineers swarm it, someone eventually finds the root cause, and then the post-mortem gets written from memory three days later with half the context already gone. The process loses information at every handoff.
Current workflow pain points:
- Incident context scattered across Slack, PagerDuty, logs, and memory
- Manual command execution slows triage (copy terminal output → paste → ask AI → repeat)
- Cloud SaaS RCA tools require uploading sensitive production data
- Generic AI assistants lack infrastructure domain expertise
- Post-mortems written days later miss critical context
Our Solution
TRCAA is a local-first, AI-powered incident triage assistant that autonomously executes diagnostic commands while you work.
Core Innovation: Agentic Shell Execution
The AI doesn't just suggest commands—it executes them directly with intelligent safety controls:
Three-Tier Safety System:
- Tier 1 (Auto-Execute): Read-only diagnostics (
kubectl get,grep,ps) run immediately - Tier 2 (User Approval): Mutating operations (
kubectl scale,systemctl restart) require explicit consent - Tier 3 (Always Deny): Destructive commands (
rm -rf,shutdown) automatically blocked
Example: You say "Why is the nginx pod crashing?" — the AI autonomously runs kubectl get pods, kubectl describe, and kubectl logs, analyzes the output, and explains the root cause. No copy-paste, no manual terminal work.
Key Differentiators
Local-First Architecture:
- SQLCipher AES-256 encrypted local storage (not cloud SaaS)
- Offline-capable via Ollama local AI models
- PII auto-detection and redaction before any cloud API calls
- Tamper-evident hash-chained audit log
Infrastructure Domain Expertise:
- Pre-built expert context for 16 domains: Linux (RHEL/OEL), Windows, Kubernetes (k3s/OpenShift/Rancher), Networking (Fortigate/Cisco/Aruba), Databases (PostgreSQL/Redis/RabbitMQ), Proxmox, HPE Synergy/iLO, Observability (Kibana/Elasticsearch)
- AI understands your stack's specifics, not generic troubleshooting
Multi-Cluster Kubernetes Support:
- Upload multiple kubeconfig files with encrypted AES-256-GCM storage
- Bundled kubectl v1.30.0 (no external dependencies)
- Switch contexts seamlessly during triage
Provider-Agnostic AI:
- OpenAI, Anthropic Claude, Google Gemini, Mistral, AWS Bedrock (via LiteLLM), local Ollama
- Auto-detect tool calling support for custom providers
- No vendor lock-in
What We Built (v1.0.0 → v1.0.9)
Initial Hackathon Release (v1.0.0)
35 files changed, +4089 lines
- Shell execution module with three-tier classifier (19 tests, 100% coverage)
- kubectl binary bundling for all platforms
- Real-time approval modal UI
- 4 new database tables (migrations 024-027)
- 7 Tauri commands + 1 AI tool registration
- Cross-platform CI/CD with GitHub Actions
Post-Hackathon Iterations (v1.0.1 → v1.0.9)
24 additional PRs merged in 48 hours, addressing real-world usage issues:
v1.0.1-v1.0.2: Security updates (vitest 4.1.8, postcss, vite), LiteLLM AWS Bedrock support, Ollama auto-start
v1.0.3-v1.0.4: Query classification (prevents AI from running 20+ commands for simple questions), graceful iteration limit handling, TFTSR GenAI gateway support
v1.0.5-v1.0.6: Agent prompt cleanup (fixed JSON output in natural language responses)
v1.0.7: Ollama function calling support (tools parameter was ignored)
v1.0.8: Connection reliability (180s timeout, health checks, 3-attempt retry logic), model recommendations (≥3B parameters required)
v1.0.9 (PR #44, in review): Auto-detect tool calling support—eliminates guesswork about whether custom AI providers support function calling
Total impact: 60 files modified, ~6,100 lines of production code, 297 backend + 134 frontend tests passing
The Competitive Landscape
What Exists (Cloud SaaS)
- Rootly: Automates postmortem/RCA process (cloud SaaS, subscription)
- incident.io: Triaging/investigating alerts in Slack/Teams (cloud SaaS, data leaves network)
- Xurrent: Auto-compiles postmortems from logs/metrics (cloud SaaS)
- TraceRoot (AWS Marketplace): 5-step investigation with AI assist (cloud SaaS, compliance framing)
Critical gap: Every competitor is cloud-hosted SaaS requiring sensitive incident data to leave your network.
What Doesn't Exist
No tool combines:
- Local-first + offline-capable execution
- Encrypted local storage (SQLCipher AES-256)
- PII sanitization before AI send
- Provider-agnostic AI (swap models without workflow changes)
- Infrastructure domain depth (16 pre-built expert contexts)
- Autonomous command execution with safety controls
- Tamper-evident audit trail
- Air-gap capable (via Ollama local models)
TRCAA occupies this unique gap.
Where We Win vs SaaS
| Dimension | TRCAA | SaaS Competitors |
|---|---|---|
| Privacy | All data local, encrypted | Incident logs on vendor servers |
| Air-gap capable | Yes (Ollama local models) | No (requires cloud) |
| Cost | One-time install | Per-seat subscription fees |
| Domain depth | 16 pre-built infrastructure contexts | Generalist troubleshooting |
| Provider choice | 6 AI providers + custom | Vendor-locked backend |
| PII protection | Auto-redact before send | Raw logs ingested |
| Compliance | Hash-chained audit trail | Varies by vendor |
Where SaaS Wins
- Alert integration: PagerDuty/Datadog/CloudWatch auto-triggers (TRCAA is manually initiated)
- Team collaboration: Multiple engineers on same incident simultaneously (TRCAA is single-user)
- Observability correlation: Tight integration with metrics/traces (incident.io cuts context-switching from 15min → 30sec)
Target market: Regulated-industry DevOps teams, defense contractors, small MSPs, air-gapped environments, solo infrastructure engineers who prioritize privacy and cost over team collaboration features.
Technical Highlights
Backend (Rust + Tauri):
- Three-tier command classifier with pipe/chain analysis and tier escalation
- Platform-specific shell execution (
cmd /Con Windows,sh -con Unix) - AES-256-GCM kubeconfig encryption with hand-rolled YAML parser (licensing constraints)
- 30-second command timeout with environment isolation (strips
AWS_ACCESS_KEY_ID, etc.) - Hash-chained audit log (tamper-evident)
Frontend (React + TypeScript):
- Real-time approval modal with risk factor display
- Multi-cluster kubeconfig manager with drag-drop upload
- Execution history with exit codes and timing
- Settings UI for tier architecture visualization
CI/CD (GitHub Actions):
- Multi-platform builds: Linux (amd64/arm64 DEB/RPM), macOS (Intel/ARM DMG), Windows (NSIS)
- kubectl binary auto-bundled for all platforms
- Branch protection requires passing tests + Copilot review before merge
Quality Assurance:
- 297 backend tests + 134 frontend tests (100% classifier coverage)
- 3 rounds of GitHub Copilot automated review (10 security/reliability findings, all resolved)
- Zero Clippy warnings, zero TypeScript errors
- TDD approach throughout
Lessons Learned
What Went Well
- TDD caught bugs early (19 classifier tests prevented regressions)
- Three-tier classification proved robust in real usage
- GitHub Copilot review identified real security issues (prompt injection risk, tool call dropping)
- Rapid iteration post-launch (24 PRs in 48 hours) addressed real user pain points
What We'd Improve
- Should have built multi-context kubeconfig support in v1.0.0 (added v1.0.9)
- Domain prompts initially didn't instruct AI to use shell execution tool (fixed v1.0.1)
- Integration tests need more coverage (mostly unit tests currently)
- Should have updated hackathon summary after each PR merge (created documentation debt)
Challenges Solved
- Cross-platform shell execution:
sh -cdoesn't exist on Windows → platform-specific shell selection withcfg!macros - AI over-investigation: Simple query "What pods are running?" triggered 20+ commands → three-tier query classification (Simple/Diagnostic/Incident)
- Ollama function calling: Provider ignored
toolsparameter → implemented proper tool formatting in request body - Connection reliability: Intermittent timeouts → extended timeout (180s for tool calling), health checks, 3-attempt retry logic
- Tool calling detection: Users unsure if custom providers support it → auto-detect with test tool call (v1.0.9)
Impact Metrics
Development Time:
- Initial hackathon (v1.0.0): ~44 hours
- Post-release iterations (v1.0.1-v1.0.9): ~28 hours
- Total: ~72 hours
Code Produced:
- Rust: ~2,200 lines (shell module + commands + AI improvements)
- TypeScript/React: ~900 lines (components + types)
- Tests: ~800 lines (431 tests total)
- Documentation: ~2,200 lines (wiki + summaries)
- Total: ~6,100 lines
PRs Merged: 25 PRs (v1.0.0 initial + 24 post-release iterations)
