observability-advisor

observability-advisor is a skill for Claude Code from wyattowalsh/agents. It costs 43 tokens per session (2,306 once invoked), scanned A, original, MIT.

A guide for designing and reviewing system telemetry: logs, metrics, traces, service-level objectives, and alerts. Telemetry is information about how a service behaves; an SLO is a target for a user-facing reliability measure.

In plain words
What is it for?
Use it to plan instrumentation, review observability coverage, define reliability targets, and design alerts for services.
Why use it?
It helps reveal missing or weak signals before reliability problems are difficult to diagnose. It provides a structured way to check whether systems can be detected and understood when they fail.

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

observability-advisor 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 1mo ago.

The scan reads SKILL.md. This mod also ships 8 executable files (scripts/asset_toolkit/__init__.py, scripts/asset_toolkit/_shared.py, scripts/asset_toolkit/common.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 Advisor

Design and review telemetry that helps teams detect, diagnose, and improve service behavior before and during reliability problems.

Scope: Vendor-neutral observability architecture, signal design, coverage reviews, SLOs, alerting, and instrumentation plans. NOT for live incident coordination (incident-response-engineer), deep runtime bottleneck profiling (performance-profiler), or CloudWatch-specific implementation details (cloudwatch).

Canonical Vocabulary

Term Definition
telemetry Logs, metrics, traces, profiles, and events emitted by a system
signal A measurable indicator used to detect or explain behavior
metric Numeric time-series measurement aggregated over time
log Structured event record capturing context for a specific occurrence
trace End-to-end record of work moving through distributed components
span A timed unit of work within a trace
SLI Concrete measurement of a user-relevant reliability property
SLO Target threshold and window for an SLI
error budget Allowed unreliability implied by an SLO over its window
cardinality Number of unique label or attribute values attached to telemetry

Dispatch

$ARGUMENTS Mode
design <system> Design an observability architecture for a service or workflow
review <service or stack> Audit existing telemetry, dashboards, and alerts
instrument <service or path> Plan what to emit and where to add instrumentation
alert <service or journey> Design actionable alerting and escalation
slo <service or journey> Define SLIs, SLOs, and error budget policy
investigate <signal or symptom> Structure cross-signal diagnosis for an issue
Natural language about logs, metrics, traces, dashboards, or alerting Auto-detect the closest mode
Empty Show the mode menu with examples

When to Use

  • A team can see failures but cannot explain them quickly
  • Alerts are noisy, late, or missing user-impact context
  • A service lacks clear SLIs, SLOs, or error budget policy
  • You need to add instrumentation to a new service, workflow, or migration
  • Dashboards exist but ownership, escalation, or runbook linkage is weak

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.

observability-advisor is a skill published in the GitHub repository wyattowalsh/agents (5 stars, last pushed 1mo ago), licensed MIT. It adds 43 tokens to every session and 2,306 once invoked, about $0.0002 per session on Opus 5.5. 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.
