agent-observability

agent-observability is a skill for Claude Code, Codex from VoDaiLocz/kilo-kit-mcp. It costs 43 tokens per session (1,050 once invoked), scanned A, original, Apache-2.0.

A guide to monitoring and tracing software agents while they run in production. It covers relationships between agent and tool calls, response time, token usage, cache performance, and repeated or looping behavior.

In plain words
What is it for?
Use it to add tracing to multi-agent workflows, monitor latency and token consumption, detect repeated tool errors or infinite loops, and create feedback for regression testing.
Why use it?
It helps explain agent failures, measure operating costs, and identify slow or stuck workflows. The collected information makes production behavior easier to inspect and improve.

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

agent-observability 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 5d 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.

Agent Observability & Telemetry

Overview

This skill defines the operational standards and instrumentation requirements for monitoring agentic workflows. It ensures that complex, multi-agent systems built within KILO-KIT remain transparent, debuggable, and cost-effective. Observability in this context spans from real-time tracing of individual subagent reasoning to macro-level analysis of cost-per-task and loop-detection across distributed systems.

When To Use

Activate this skill when:

  • Designing new complex agent workflows requiring distributed tracing.
  • Debugging performance regressions or unexplained agent failures.
  • Implementing production monitoring for cost optimization.
  • Setting up feedback loops for regression testing based on real production traces.
  • Configuring OpenTelemetry or integrating with observability platforms like Langfuse/Helicone.

Core Pillars

  1. Traceability: Capturing parent-child relationships across subagent calls and tool invocations.
  2. Quantification: Measuring latency, token consumption, and cache effectiveness.
  3. Detection: Identifying anomalies in agent behavior (e.g., infinite recursion, repetitive tool errors).
  4. Learning: Converting trace data into gold-standard datasets for future regression testing.

Instrumentation Workflow

To maintain high observability, follow this workflow:

  1. Context Propagation: Always pass trace_id and span_id headers through all agent boundaries.
  2. Structured Logging: Log all input/output payloads at the start and end of every tool call or reasoning step.
  3. Telemetry Standards: Use OpenTelemetry semantic conventions for LLM operations (e.g., llm.request.model, llm.usage.completion_tokens).
  4. Platform Integration: Configure the agent SDKs to push spans directly to backend exporters (Langfuse/Helicone/Jaeger).
  5. Session Aggregation: Group all traces belonging to a single user task under a persistent session_id.

Key Metrics

  • Token Efficiency: Completion tokens vs. prompt tokens ratio.
  • Cost per Task: Real-time dollar cost of the entire agentic conversation.
  • Latency Breakdown: Time spent in LLM inference vs. external tool execution.
  • Cache Hit Ratio: Effectiveness of persistent caching layers for repetitive queries.
  • Reasoning Depth: Number of steps taken to arrive at a solution.

agent-observability is a skill published in the GitHub repository VoDaiLocz/kilo-kit-mcp (26 stars, last pushed 4d ago), licensed Apache-2.0. It adds 43 tokens to every session and 1,050 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
