testland/mttr-mtbf-tracker

Reference for tracking MTTR (Mean Time To Recovery) / MTBF (Mean Time Between Failures) / MTTD (Mean Time To Detection) / MTTA (Mean Time To Acknowledge) - incident-record schema, calculation formulae, dashboards-as-code, target-vs-actual alerting. Aligns with ITIL incident management + ISO 20000 + Google SRE incident response chapter. Use when incident reporting is being stood up from scratch, or when an existing MTTR / MTBF dashboard reports numbers nobody can reproduce or agree on the definition of.

Quality

Content

87%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is a well-structured, mostly copy-paste-ready reference for incident metrics with concrete schema, formulae, dashboards, and a worked example. Its main gap is implicit rather than explicit validation checkpoints in the workflow.

Suggestions

Add an explicit verification checkpoint in 'How to use' — e.g., after computing metrics, validate each incident passes the Step 3 exclusion filter and that timestamps are distinct before accepting the window.

Replace the MTBF Grafana placeholder ('... (your time-series store DSL)') with a concrete example expr or a clearly justified note on why it is store-specific.

Tighten acronym/term expansions like 'ITIL 4 (Information Technology Infrastructure Library)' since the target audience already knows these.

DimensionReasoningScore

Conciseness

The body is dense with concrete artifacts (JSON schema, formulae, Grafana/Prometheus YAML, tables) and minimal prose; it assumes SRE/ITIL competence rather than explaining basics, so most tokens earn their place.

3 / 3

Actionability

Provides a copy-paste-ready incident schema, explicit formulae, a Grafana panel fragment, a Prometheus alert rule, and a fully worked numeric example; the only placeholder (MTBF expr) is explicitly flagged as store-dependent.

3 / 3

Workflow Clarity

The 'How to use' section gives a clear 7-step sequence, but validation/checkpoint steps are implicit rather than explicit (no validate-then-proceed or retry loops), so it sits below the explicit-checkpoint anchor.

2 / 3

Progressive Disclosure

A single self-contained reference with well-organized sections (When/How to use, Steps 1-8, Worked example, Anti-patterns, Limitations, References) and only one-level-deep external references (Google SRE URL), with no nested file indirection.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific, third-person, and pairs a clear capability list with an explicit 'Use when' trigger covering both greenfield and audit scenarios. It is concise for the breadth it covers and unlikely to conflict with sibling skills.

DimensionReasoningScore

Specificity

Lists several concrete capabilities — 'incident-record schema, calculation formulae, dashboards-as-code, target-vs-actual alerting' — across the four named metrics, matching the multiple-specific-actions anchor.

3 / 3

Completeness

Explicitly answers both what (the schema, formulae, dashboards, alerting) and when via a clear 'Use when...' clause with two concrete trigger scenarios.

3 / 3

Trigger Term Quality

Natural trigger terms an SRE/on-call user would say appear directly: 'MTTR / MTBF dashboard reports numbers nobody can reproduce or agree on the definition of' and 'incident reporting is being stood up from scratch'.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche (incident-response metric definition/reproducibility) with distinct triggers unlikely to fire for unrelated skills.
