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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 5 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00093 | $0.00584 |
| Opus 5 | $0.00046 | $0.00292 |
| Sonnet 5 | $0.00019 | $0.00117 |
| Haiku 4.5 | $0.00009 | $0.00058 |
Grade A, and why
kb-agentcore-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 8d 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
AgentCore Observability ナレッジ
この SKILL.md は入口だけに絞っている。作業内容に近い参照ファイルを1〜2個だけ読み、不要な大型ナレッジをまとめて読まない。
参照ルール
先に AWS Agent Toolkit を当たる。 この領域は
aws-agents:agents-optimize、aws-core:aws-observabilityがカバーする。 このスキルは Toolkit の代わりではなく、公式どおりにやったのに動かなかったときの原因を貯めておく場所として使う。 Toolkit 側が同じ内容をカバーしたと分かった項目は、このスキルから削る（両方に置くと、更新されるのは公式側だけなのでこちらが古い情報の発生源になる）。
- まず依頼内容から必要な参照ファイルを選ぶ。
- 最新仕様や外部サービス仕様が関係する場合は、参照ファイルだけで断定せず公式ドキュメント・MCP・実コードで確認する。
- 複数領域にまたがる場合も、読み込む参照は最小限から始める。

What ships with it
7 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.

kb-agentcore-observability is a skill published in the GitHub repository minorun365/my-claude-code-settings (129 stars, last pushed 9d ago), licensed MIT. It adds 93 tokens to every session and 584 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.
