team-observability

team-observability is a skill for Claude Code from ketor/cto-fleet. It costs 130 tokens per session (6,325 once invoked), scanned B, original, Apache-2.0.

A coordinated workflow for designing service monitoring. It maps how services connect, proposes service health measures (SLIs), targets (SLOs), alert rules, and monitoring configuration, with Prometheus as the default.

In plain words
What is it for?
Use it to scan a project or named service, design monitoring and alerts, and generate deployable Prometheus, Datadog, or CloudWatch configuration.
Why use it?
It reduces the work of turning an unfamiliar service layout into monitoring rules. It also compares two independent designs before producing the configuration.

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 B, and why

team-observability scanned grade B with 1 finding 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 6d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 500 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Preamble (run first)

_UPD=$(~/.claude/skills/cto-fleet/bin/cto-fleet-update-check 2>/dev/null || true)
[ -n "$_UPD" ] && echo "$_UPD" || true

If output shows UPGRADE_AVAILABLE <old> <new>: read ~/.claude/skills/cto-fleet/cto-fleet-upgrade/SKILL.md and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If JUST_UPGRADED <from> <to>: tell user "Running cto-fleet v{to} (just updated!)" and continue.

参数解析:从 $ARGUMENTS 中检测以下标志:

  • --auto:完全自主模式(不询问用户任何问题,全程自动决策)
  • --once:单轮确认模式(将所有需要确认的问题合并为一轮提问,确认后全程自动执行)
  • --stack=prometheus|datadog|cloudwatch:目标监控栈(默认 prometheus
  • --service=服务名:聚焦特定服务(可选,默认全量扫描)
模式 用户确认范围 条件节点处理
标准模式(默认) 拓扑确认 + 设计分歧仲裁 + 最终配置确认 正常询问用户
单轮确认模式--once 仅最终配置确认 自动决策 + 收尾汇总
完全自主模式--auto 不询问用户 全部自动决策,收尾汇总所有决策

单轮确认模式下条件节点自动决策规则:

  • SLO 阈值不确定 → team lead 根据行业惯例自行判断,在最终配置中说明
  • 两位 designer 分歧 → team lead 标注分歧,综合论证后裁决,收尾时汇总
  • 分歧超过 50%不可跳过,必须暂停问用户(熔断机制)
  • 交叉验证异议超过 3 项不可跳过,必须暂停问用户(熔断机制)
  • 服务拓扑过大无法完整覆盖 → topology-scanner 识别核心服务链路,designer 聚焦核心链路
  • --service 参数处理:如果用户指定了 --service,topology-scanner 和 designer 优先分析指定服务及其上下游,其余服务仅概览级别

完全自主模式下:所有节点均自动决策,不询问用户。熔断机制仍然生效(分歧超过 50%、交叉验证异议超过 3 项时仍必须暂停问用户)。

监控栈支持说明:

支持级别 说明
prometheus 完整支持 原生 YAML 配置生成(Prometheus rules + Alertmanager + Grafana dashboards)
datadog 尽力支持 SLI/SLO 定义和告警逻辑栈无关;配置格式为 Datadog Monitor JSON,best-effort
cloudwatch 尽力支持 SLI/SLO 定义和告警逻辑栈无关;配置格式为 CloudWatch Alarm JSON/CloudFormation,best-effort

使用 TeamCreate 创建 team(名称格式 team-observability-{YYYYMMDD-HHmmss},如 team-observability-20260308-143022,避免多次调用冲突),你作为 team lead 按以下流程协调。

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.
