What is observability?

A toolkit for monitoring and debugging web, Node.js, and Python applications. It follows requests across the browser and backend, records logs and outgoing network calls, and reads distributed traces, which show how one request moves through connected services.

Use it to inspect console errors, network requests, outgoing HTTP calls, and end-to-end request traces.

It helps locate where a request fails or slows down when the cause may be spread across the browser, server, or other services.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00088	$0.02320
Opus 5	$0.00044	$0.01160
Sonnet 5	$0.00018	$0.00464
Haiku 4.5	$0.00009	$0.00232

Security

Grade A, and why

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 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.

Observability Skill

Monitor and debug web, Node.js, and Python applications using OpenTelemetry, console logs, network requests, outbound (egress) HTTP capture, and distributed tracing.

When to Use

This skill activates when:

User asks about distributed tracing
User wants to correlate frontend and backend requests
User mentions OpenTelemetry, Jaeger, Zipkin, or tracing
User needs to debug request flow across services
User wants to see which downstream services a Node.js/Python process calls (egress)
User wants to monitor application behavior

Capabilities

Distributed Tracing

# Pin / inspect the session trace context
ironbee-browser-devtools-cli o11y get-trace-context
ironbee-browser-devtools-cli o11y new-trace-id
ironbee-browser-devtools-cli o11y set-trace-context --trace-id "abc123def456..."

# Read the spans back from the IronBee platform
ironbee-browser-devtools-cli --json o11y get-trace --wait-ms 10000
ironbee-browser-devtools-cli --json o11y get-session-traces --status error

Console Monitoring

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.

observability is a skill published in the GitHub repository ironbee-ai/ironbee-devtools-skills (3 stars, last pushed 1mo ago), licensed MIT. It adds 88 tokens to every session and 2,320 once invoked, about $0.0004 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 2026-08-31.
