llms: Skill for Claude Code

.claude/skills/ops/SKILL.md

ops is a skill for Claude Code from matteocervelli/llms. It costs 67 tokens per session (1,154 once invoked), scanned A, original, MIT.

A production monitoring setup guide for live services, covering structured logs, request and error metrics, dashboards, and service-level alerts. Observability means collecting information that shows how a running service behaves.

In plain words
What is it for?
Use it to add logging, Prometheus metrics, Grafana or similar dashboards, and alerts based on service objectives.
Why use it?
It helps teams notice failures, slowdowns, and reliability problems after deployment instead of relying only on user reports.

This is matteocervelli/llms's own configuration. It tells Claude Code how to work on llms itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything llms configures →

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

ops 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 3d 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.

Ops — Post-Deploy Observability

Unified observability guidance for production services. Auto-detects context from project files or accepts explicit mode.

Usage

/ops                  # Auto-detect from project signals
/ops logging          # Explicit: structured logging setup
/ops metrics          # Explicit: RED metrics + Prometheus instrumentation
/ops dashboard        # Explicit: Grafana/DataDog/CloudWatch dashboards
/ops alerting         # Explicit: SLO-based alerting policy
/ops overview         # Cross-mode sequencing guide

Workflow

Step 1: Determine Context

Parse $ARGUMENTS for explicit mode. If no arguments, run context detector:

DETECTED=$(bash "$HOME/.claude/skills/ops/lib/context-detector.sh")

Step 2: Show Relevant Guidance

Based on detected or explicit mode, use progressive disclosure:

Level 1 — Summary (default, ~20 lines): Read and present the summary template for the detected mode. This is the entry point.

Level 2 — Patterns (on request, ~60-80 lines): When the user asks for more detail, "show me patterns", code examples, or "Don't/Do/Best" style guidance, read the patterns template.

Level 3 — Full SOP (future): Not yet available. If the user asks for a complete reference, offer to dive into patterns and answer specific questions.

Step 3: Handle Multiple Contexts

If context-detector returns multiple modes (e.g., "logging,metrics"):

  • Show summary for each detected mode
  • Ask: "Which area do you want to dive deeper into?"

Step 4: No Context Detected

If detection returns "none" and no explicit mode was given:

  • Read and show templates/overview.md
  • Let the user choose which mode to start with

Template Locations

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.
