observability-instrumentation from tylerjrbuell/reactive-agents-ts is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add tylerjrbuell/reactive-agents-ts/observability-instrumentation@v2.0Pins v2.0 in mdr.lock. Pin the fingerprint instead.

Configure verbosity levels, live log streaming, JSONL file export, model I/O logging, and audit trails for monitoring agent execution.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Observability and Instrumentation
## Agent objective
Produce a builder with observability configured at the right verbosity level, with optional live streaming and file export, so agent execution can be monitored and debugged.
## When to load this skill
- Debugging unexpected agent behavior in development
- Capturing structured logs for post-hoc analysis
- Streaming live execution traces to a dashboard or log aggregator
- Auditing all tool calls and model decisions in production
- Comparing model I/O before/after a system prompt change
## Implementation baseline
```ts
import { ReactiveAgents } from "@reactive-agents/runtime";
const agent = await ReactiveAgents.create()
.withName("monitor")
.withProvider("anthropic")
.withReasoning({ defaultStrategy: "adaptive", maxIterations: 10 })
.withTools({ allowedTools: ["web-search", "http-get", "checkpoint"] })
.withObservability({
verbosity: "normal", // show metrics dashboard on completion
live: true, // stream events as they happen
file: "./logs/agent.jsonl", // write structured JSONL log
})
.withAudit() // record all tool calls and decisions
.build();
```

How to install
mdr add tylerjrbuell/reactive-agents-ts/observability-instrumentation@sha256:f9469e4ddcc53c37The line at the top of this page pins the label v2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
