When the bundled explain-usage skill resolves in this session, prefer it for a plain-language breakdown of this session's tokens; this skill for cross-session reports from the local telemetry stores (OTEL DuckDB, hook event log, ccusage): token burn, cost, hook latency, per-session activity, usage per work item; read-only except the explicit clean action. Use when: 'claude observability', 'how am I doing', 'what did this session do', 'which hooks fired', 'compare two sessions', 'tokens per work…

Safer alternatives
Low-risk skills in the same category (coding) that look related. Check that one does what you need.
Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'observability' ] || [ -L ~/.agents/skills/'observability' ]; then echo 'A skill folder named observability already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/melodic-software/claude-code-plugins' "$d" && git -C "$d" checkout --quiet '677e7988f432dacb5e2d4df2b124f96da8e8f9f3' -- 'plugins/harness-ops/skills/observability' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/harness-ops/skills/observability' ~/.agents/skills/'observability' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'observability' ~/.claude/skills/'observability' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
