2 match(es)

Works out of the box, but fastest with ripgrep installed.

Install

# Run directly (no install needed)
uvx search-claude-history "pattern"

# Or install globally
uv tool install search-claude-history

# With hyperscan for faster searches (matches ripgrep speed)
uv tool install "search-claude-history[hyperscan]"

Requires uv. No system Python needed.

Usage

sch <pattern> [options]

Flag	Description
-p, --project	Filter to a project (substring match on dir name)
-t, --type	Filter by role: user or assistant
-A N	Show N messages after each match
-B N	Show N messages before each match
-C, --context	Chars of text context around match (default 200)
--since TIME	Only messages at/after TIME (ISO 8601 or relative: 30m, 2h, 1d, 1w)
--until TIME	Only messages at/before TIME (same formats as --since)
--tools	Include tool_use/tool_result messages (hidden by default)
--no-color	Disable colored output

Examples

sch "database migration"                  # search everything
sch "TypeError" --type assistant          # only assistant messages
sch "deployment" -p myproject             # filter to a project
sch "refactor" -B 1 -A 1                 # show surrounding messages
sch "SELECT.*FROM" --tools               # search tool calls too
sch "deploy" --since 1w                   # only the last week
sch "error" --since 2026-04-01 --until 2026-04-10

Performance

Searches ~/.claude/projects/ using the fastest available engine:

Engine	0.45 GB	Requires
ripgrep	0.13s	rg on PATH
hyperscan	0.15s	install with [hyperscan] extra
stdlib (mmap + multiprocessing)	0.64s	nothing

The tool uses whichever engine is available, in the order above.

Respects CLAUDE_CONFIG_DIR if set, otherwise defaults to ~/.claude/.

Claude Code Skill

This tool can also be installed as a Claude Code skill to help Claude automatically search conversation history when you reference past work.

Install as Skill

mkdir -p ~/.claude/skills/search-history
curl -o ~/.claude/skills/search-history/SKILL.md https://raw.githubusercontent.com/wakamex/search-claude-history/main/skill/SKILL.md

Or manually download SKILL.md into ~/.claude/skills/search-history/.

Note: The skill works with or without installing the tool. If sch is not installed, Claude will use uvx search-claude-history (requires uv).

How It Works

Once installed, Claude will automatically use the skill when you:

• Reference past work ("a few days ago", "last week", "previously")
• Ask about prior conversations or decisions
• Want to find when something was discussed
• Need to recall specific commands or errors from earlier sessions

The skill teaches Claude how to construct effective sch queries with appropriate patterns, context flags, and filtering options.
