Cross-Project Analytics Query local analytics data from ~/.claude/analytics/ . All data is local-only, privacy-safe (hashed project IDs, no PII). Subcommands Parse the user's argument to determine which report to show. If no argument provided, use AskUserQuestion to let them pick.

summary

— Run the jq query from

Read("${CLAUDE_SKILL_DIR}/references/jq-queries.md")

for the matching subcommand. Present results as a markdown table.

session

— Follow the 4-step process in

Read("${CLAUDE_SKILL_DIR}/references/session-replay.md")

locate session file, resolve reference (latest/partial/full ID), parse JSONL, present timeline.

cost

— Apply model-specific pricing from

Read("${CLAUDE_SKILL_DIR}/references/cost-estimation.md")

to CC's stats-cache.json. Show per-model breakdown, totals, and cache savings.

trends

— Follow the 4-step process in

Read("${CLAUDE_SKILL_DIR}/references/trends-analysis.md")

daily activity, model delegation, peak hours, all-time stats. summary — Run all subcommands and present a unified view: total sessions, top 5 agents, top 5 skills, team activity, unique projects.
