Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00062 | $0.01227 |
| Opus 5 | $0.00031 | $0.00613 |
| Sonnet 5 | $0.00012 | $0.00245 |
| Haiku 4.5 | $0.00006 | $0.00123 |
Grade A, and why
adk-observability-guide 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 6d 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.

ADK Observability Guide
Iron Law
NEVER ship a production ADK agent without Cloud Trace enabled. Set otel_to_cloud=True in the FastAPI app and LOGS_BUCKET_NAME env var before any production deployment.
Reference Files
| File | Contents |
|---|---|
reference/cloud-trace-and-logging.md |
Cloud Trace setup, prompt-response logging infrastructure, environment variables, enabling/disabling locally, verification commands |
reference/bigquery-agent-analytics.md |
BigQuery Agent Analytics plugin — enabling, key features, tool provenance tracking |
reference/slo-alerting.md |
SLO-based burn-rate alerting (vs threshold alerting), multi-window pattern, error budget tracking, PromQL examples for availability/latency/safety SLOs |
Observability Tiers
| Tier | What It Does | Default State | Best For |
|---|---|---|---|
| Tier 1: Cloud Trace | Distributed tracing — execution flow, latency, errors via OpenTelemetry spans | Always-on | Debugging latency, understanding agent execution flow |
| Tier 2: Prompt-Response Logging | GenAI interactions exported to GCS, BigQuery, and Cloud Logging | Disabled locally; enabled when deployed | Auditing LLM interactions, compliance |
| Tier 3: BigQuery Agent Analytics | Structured agent events (LLM calls, tool use, outcomes) to BigQuery | Opt-in (--bq-analytics at scaffold time) |
Conversational analytics, custom dashboards, LLM-as-judge evals |
| Tier 4: SLO Alerting | SLO-based burn-rate alerts (availability, latency, safety) via Prometheus — fires only when error budget is genuinely at risk | Opt-in — requires Prometheus + Alertmanager stack | Production alerting for agentic AI services; replaces naive threshold alerts |
Ask the user which tier(s) they need — they can be combined. Tier 1 is mandatory; Tiers 2, 3, and 4 are additive.
Quick Setup
Tier 1: Cloud Trace (Always-On)
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

adk-observability-guide is a skill published in the GitHub repository kumaran-is/claude-code-onboarding (35 stars, last pushed 2mo ago), licensed MIT. It adds 62 tokens to every session and 1,227 once invoked, about $0.0003 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.
