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.

Subcommand	Description	Data Source	Reference
agents	Top agents by frequency, duration, model breakdown	agent-usage.jsonl	references/jq-queries.md
models	Model delegation breakdown (opus/sonnet/haiku)	agent-usage.jsonl	references/jq-queries.md
skills	Top skills by invocation count	skill-usage.jsonl	references/jq-queries.md
hooks	Slowest hooks and failure rates	hook-timing.jsonl	references/jq-queries.md
teams	Team spawn counts, idle time, task completions	team-activity.jsonl	references/jq-queries.md
session	Replay a session timeline with tools, tokens, timing	CC session JSONL	references/session-replay.md
cost	Token cost estimation with cache savings	stats-cache.json	references/cost-estimation.md
trends	Daily activity, model delegation, peak hours	stats-cache.json	references/trends-analysis.md
summary	Unified view of all categories	All files	references/jq-queries.md

Quick Start Example

# Top agents with model breakdown
jq -s 'group_by(.agent) | map({agent: .[0].agent, count: length}) | sort_by(-.count)' ~/.claude/analytics/agent-usage.jsonl

# All-time token costs
jq '.modelUsage | to_entries | map({model: .key, input: .value.inputTokens, output: .value.outputTokens})' ~/.claude/stats-cache.json

Quick Subcommand Guide

agents, models, skills, hooks, teams, summary — Run the jq query from references/jq-queries.md for the matching subcommand. Present results as a markdown table.

session — Follow the 4-step process in references/session-replay.md: locate session file, resolve reference (latest/partial/full ID), parse JSONL, present timeline.

cost — Apply model-specific pricing from 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 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.

Data Files

See references/data-locations.md for complete data source documentation.

File	Contents
agent-usage.jsonl	Agent spawn events with model, duration, success
skill-usage.jsonl	Skill invocations
hook-timing.jsonl	Hook execution timing and failure rates
session-summary.jsonl	Session end summaries
task-usage.jsonl	Task completions
team-activity.jsonl	Team spawns and idle events

Rules

Each category has individual rule files in rules/ loaded on-demand:

Category	Rule	Impact	Key Pattern
Data Integrity	rules/data-privacy.md	CRITICAL	Hash project IDs, never log PII, local-only
Cost & Tokens	rules/cost-calculation.md	HIGH	Separate pricing per token type, cache savings
Performance	rules/large-file-streaming.md	HIGH	Streaming jq for >50MB, rotation-aware queries
Visualization	rules/visualization-recharts.md	HIGH	Recharts charts, ResponsiveContainer, tooltips
Visualization	rules/visualization-dashboards.md	HIGH	Dashboard grids, stat cards, widget registry

Total: 5 rules across 4 categories

References

Reference	Contents
references/jq-queries.md	Ready-to-run jq queries for all JSONL subcommands
references/session-replay.md	Session JSONL parsing, timeline extraction, presentation
references/cost-estimation.md	Pricing table, cost formula, daily cost queries
references/trends-analysis.md	Daily activity, model delegation, peak hours queries
references/data-locations.md	All data sources, file formats, CC session structure

Important Notes

• All files are JSONL (newline-delimited JSON) format
• For large files (>50MB), use streaming jq without -s — see rules/large-file-streaming.md
• Rotated files: <name>.<YYYY-MM>.jsonl — include for historical queries
• team field only present during team/swarm sessions
• pid is a 12-char SHA256 hash — irreversible, for grouping only

Output Format

Present results as clean markdown tables. Include counts, percentages, and averages. If a file doesn't exist, note that no data has been collected yet for that category.
