Insights Archive

Archive and manage Claude Code /insights reports to track how your usage patterns evolve over time.

Usage

/insights-archive archive      # Save current report with timestamp
/insights-archive list         # See all archived reports
/insights-archive open         # Open current report in browser
/insights-archive open <date>  # Open archived report by date
/insights-archive diff <d1> <d2>  # Compare two archived reports
/insights-archive              # Show help

Configuration

INSIGHTS_DIR=~/.claude/usage-data
ARCHIVE_DIR=~/.claude/usage-data/archives
CURRENT_REPORT=~/.claude/usage-data/report.html

Implementation

This skill is fully self-contained. Do NOT download or execute any external scripts. All logic is implemented directly below using the allowed tools.

Input Validation

Before processing any command, validate all user-provided arguments:

Subcommand must be one of: archive, list, open, diff, or empty (show help)
Date arguments (for open and diff) must match the pattern YYYY-MM-DD or YYYY-MM-DD-HHMM (digits and hyphens only). Reject any argument containing characters other than [0-9-] or the literal string current.
If validation fails, show the help text and stop.

Commands

No arguments / help

If no arguments are provided or the subcommand is not recognized, display:

Usage: /insights-archive <command> [args]

Commands:
  archive          Archive current /insights report with timestamp
  list             List all archived reports
  open [date]      Open current report or archived report by date
  diff <d1> <d2>   Open two reports for comparison

Examples:
  /insights-archive archive
  /insights-archive list
  /insights-archive open current
  /insights-archive open 2026-02-04
  /insights-archive diff 2026-02-01 2026-02-04

list

List archived reports using Glob for ~/.claude/usage-data/archives/report-*.html
If no files found, tell the user: "No archived reports found. Run '/insights-archive archive' to create one."
Otherwise, display the list with dates extracted from filenames (strip report- prefix and .html suffix), and remind: "Use '/insights-archive open <date>' to view one."

open

Validate the date argument (must be current, empty, or match [0-9-]+).

If argument is empty or current:

test -f ~/.claude/usage-data/report.html && open ~/.claude/usage-data/report.html || echo "missing"

If missing, tell user to run /insights first.

If a date is provided, use Glob to find matching files: ~/.claude/usage-data/archives/report-<DATE>*.html
- If exactly one match, open it:
```
open <matched-file>
```
- If no matches, tell the user and suggest running list.
- If multiple matches, show them and ask the user to be more specific.

diff

Require exactly two date arguments. If not provided, show usage: "Usage: /insights-archive diff <date1> <date2>"
Validate both date arguments (must match [0-9-]+).
Find matching archives for each date using Glob: ~/.claude/usage-data/archives/report-<DATE>*.html
If either date has no match, report which one is missing.
If both found, open them:
```
open <file1> && open <file2>
```
Tell the user: "Opening both reports for comparison."

Why Archive?

Tracking how your Claude Code usage patterns evolve over time is valuable:

See workflow improvements — Are git operations decreasing as you add custom skills?
Track friction resolution — Did the suggestions from last month's report get addressed?
Measure learning — How are your interaction patterns maturing?

This aligns with the "knowledge compounds" thesis — your usage data is another form of knowledge that benefits from historical context.
