metricas

metricas is a skill for Claude Code, Codex from igoruehara/spec-driven. It costs 98 tokens per session (1,059 once invoked), scanned A, original, MIT.

A delivery-metrics skill that tracks Lead Time, the time from starting work to production, and Throughput, the number of items completed in a period. It also reviews Continuous Delivery, where releases are kept ready, versus Continuous Deployment, where approved changes are released automatically.

In plain words
What is it for?
Use it to calculate delivery times and completed work from available project sources, compare trends by period or work type, assess release automation, and track test coverage and static-analysis results.
Why use it?
It shows where work slows down and whether delivery and code-quality practices are improving, without using the numbers to rank individual people.

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

metricas 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 5d 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.

Skill: Métricas de entrega (Lead Time · Throughput · CD)

Acompanha a saúde do fluxo de entrega. Idempotente: re-rodar recalcula o período. Princípio: usar para achar gargalo, não para ranquear pessoas (não incentive gaming).

Defina o período

Pergunte (AskUserQuestion) o ciclo (sprint / semana / mês) e a janela de datas.

1. Lead Time — quanto tempo até produção

Tempo de "começou" → "em produção" por item.

  • Início (use o que houver): data da spec/STATE, criação da issue (Jira) ou 1º commit.
  • Fim: deploy em prod — tag/release, log de CI/CD, ou status "done" do Jira.
  • Calcule por item e o agregado: mediana e p85 (mais robusto que média). Quebre por tier/tipo (feature/bug) se útil.

2. Throughput — itens concluídos no ciclo

Número de itens que chegaram a "pronto"/prod no período (histórias, bugs, tarefas).

  • Fontes: specs/ marcadas implementadas, PRs mergeados, issues fechadas (Jira), deploys.
  • Reporte o número absoluto por ciclo e a tendência (↑ / → / ↓ vs ciclo anterior).

3. Continuous Delivery vs Continuous Deployment

Avalie onde o time está e o gap:

Prática Definição Pergunta de verificação
Continuous Delivery toda mudança fica deployável (pipeline verde); o release é decisão de negócio (um botão) o pipeline garante deployabilidade? há staging?
Continuous Deployment toda mudança aprovada vai para prod automaticamente, sem gate manual ainda há gate manual? quanto da pipeline é automático?
  • Reporte também a Deployment Frequency (quantos deploys no período).
  • Aponte o próximo passo de automação → /setup-ci.

4. Qualidade de código — cobertura e análise estática

Evidência rastreável do resultado (não só do fluxo). Olhe a tendência, não o número isolado — e nunca para ranquear pessoas (não incentive gaming: 100% de cobertura com testes vazios é pior que 80% honesto).

  • Cobertura: % atual (global e, se útil, por módulo/camada) e a tendência vs ciclo anterior. Fonte: relatório de cobertura da CI (artefato — ver /setup-ci) ou <comando de cobertura> local.
  • Análise estática: nº de findings por severidade (type-check, complexidade/smells, SAST/segurança, duplicação) e a tendência. Fonte: relatório do CI (Sonar/CodeQL/semgrep/ruff/tsc…).
  • Ligação com o gate: cobertura abaixo do mínimo ou finding bloqueante barra o merge (ver docs/engineering/TESTING.md); o resto entra aqui como tendência a vigiar (dívida acumulando?).

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.

metricas is a skill published in the GitHub repository igoruehara/spec-driven (213 stars, last pushed 1mo ago), licensed MIT. It adds 98 tokens to every session and 1,059 once invoked, about $0.0005 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 2026-08-30.
