Sentinel-AIOps: Instructions file for Codex

AGENTS.md

Sentinel-AIOps AGENTS.md is an instructions file for Codex, OpenCode from Anbu-00001/Sentinel-AIOps. It costs 520 tokens per session, scanned A, original, MIT.

Project instructions for Sentinel-AIOps, a system that detects unusual continuous-integration and deployment logs and helps fix the underlying problems. It describes the project’s machine-learning models, infrastructure, and workflow rules.

In plain words
What is it for?
It helps guide development of Sentinel-AIOps, including its Python models for classifying build failures, detecting unfamiliar incidents, monitoring data drift, and handling the surrounding infrastructure.
Why use it?
It gives an coding agent the project context and constraints needed to work consistently on the system. It also explains how known failures, new kinds of incidents, and changes in live data are detected.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Sentinel-AIOps AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

🛡️ Sentinel-AIOps Mission Briefing

🎯 Project Mission

Sentinel-AIOps is an autonomous system designed for CI/CD log anomaly detection and remediation within the Antigravity ecosystem.

🧠 Technical Core

Our intelligence relies on Python-based Machine Learning models:

  • LightGBM Multiclass Classifier: Supervised model classifying CI/CD logs into 10 failure categories using numerical telemetry features (CPU usage, build duration, memory consumption, retry count). Macro F1 ≈ 0.89 on a balanced 10-class test set. Ablation-verified: removing TF-IDF features reduces F1 by only 0.004 points, confirming the model learns from operational telemetry — not log text.
  • Isolation Forest: Unsupervised anomaly detector for out-of-distribution logs that don't match any known failure pattern, flagging novel infrastructure incidents.
  • PSI Drift Monitor: Population Stability Index tracking that compares live inference distributions against the training baseline across all numerical and categorical features. Triggers a retrain recommendation when any feature PSI exceeds 0.20.

🏗️ Infrastructure

The system follows a robust, local-first architecture:

  • Inference Engine: Powered by a FastMCP server for low-latency, localized model inference.
  • Observability Interface: A FastAPI dashboard providing real-time health badges, PSI drift heatmaps, inference history, and GitHub webhook ingestion.

📜 Workflow Rules

All autonomous agents interacting with this project MUST adhere strictly to the following operational protocols:

  1. Always log 'Reasoning' before execution: Every action must be preceded by a clear, documented rationale.
  2. Save all ML metrics as 'Artifacts': Performance metrics (specifically F1-Score and PR AUC) must be rigorously tracked and saved as permanent project artifacts.

📁 Directory Map

The project is structurally divided into the following key domains:

  • /data: For storing raw logs and processed datasets used in model training and inference.
  • /models: For housing the trained weights and configurations of our Isolation Forest and LightGBM models.
  • /mcp-server: For containing the FastMCP-based local inference logic and API endpoints.
  • /dashboard: For the Next.js frontend code providing the observability and monitoring interface.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
