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 | $0.00056 | $0.00447 |
| Opus 5 | $0.00028 | $0.00224 |
| Sonnet 5 | $0.00011 | $0.00089 |
| Haiku 4.5 | $0.00006 | $0.00045 |
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 4d 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.
What it actually says
Observability
Implement the three pillars of observability: logs, metrics, and traces.
The Three Pillars
| Pillar | Purpose | Key Question |
|---|---|---|
| Logs | Discrete events with context | What happened? |
| Metrics | Aggregated measurements | How much/many? |
| Traces | Request flow across services | Where did time go? |
Quick Pick
- Debug specific request? → Logs + Traces
- Alert on thresholds? → Metrics
- Understand system health? → All three
- Starting from zero? → Logs first, then metrics, then traces
Key Principles
- Use structured logging (JSON) with correlation IDs across all services
- Instrument the four golden signals: latency, traffic, errors, saturation
- Define SLIs/SLOs before building dashboards or alerts
- Alert on symptoms (user impact), not causes (CPU usage)
Quick Start Checklist
- Set up structured logger (Pino recommended for Node.js)
- Add request correlation IDs (middleware)
- Instrument key metrics (RED: Rate, Errors, Duration)
- Configure distributed tracing (OpenTelemetry)
- Create dashboards for golden signals
- Set up alerts with appropriate severity levels

What ships with it
4 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.

observability is a skill published in the GitHub repository srstomp/pokayokay (9 stars, last pushed 2mo ago), licensed MIT. It adds 56 tokens to every session and 447 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 2026-08-31.
