| description | Query and analyze Claude Code + Codex CLI history joined with Git data and source code using SQL. Use when user asks about conversation history, productivity patterns, commit correlation, session analytics, codebase analysis, symbol search, file context, or impact analysis. |
Query Claude Code and Codex CLI history joined with Git commits and source code to analyze productivity patterns and understand codebases.
Ensure devsql is installed:
brew install douglance/tap/devsql
For structured queries, prefer these subcommands (they return JSON):
| Command | Use When |
|---|---|
devsql search "<query>" | Finding symbols by name (functions, classes, structs). Supports --kind filter and --limit. |
devsql context <file> | Getting file metadata + all symbols defined in a file. |
devsql history <file> | Showing Git commit history for a specific file with diff stats. |
devsql diff <base> <head> | Comparing two Git refs with file-level and symbol-level change analysis. |
devsql impact <file> | Analyzing a file's exports and finding potential dependents via imports. |
All commands accept --repo / -r and --data-dir / -d options.
| Table | Columns |
|---|---|
history | timestamp, display (prompt text), project, pastedContents |
jhistory | session_id, ts, text, display, timestamp |
codex_history | Alias of jhistory |
transcripts | type, content, tool_name, session_id |
todos | content, status |
| Table | Columns |
|---|---|
commits | id, message, summary, author_name, authored_at, short_id |
branches | name, is_head, commit_id |
diffs | commit_id, files_changed, insertions, deletions |
diff_files | commit_id, path, status (A/D/M/R/C), insertions, deletions |
| Table | Columns |
|---|---|
source_files | path, name, extension, directory, size_bytes, line_count, modified_at, language |
source_lines | file_path, line_number, content, is_blank |
symbols | file_path, name, kind, line_start, line_end, signature, visibility, parameters, return_type, language |
imports* | file_path, line_number, module, name, alias, kind, is_default, is_wildcard |
ast_nodes* | (requires tree-sitter-ast feature) |
* Full extraction requires the tree-sitter-ast build feature. Without it, symbols uses regex-based extraction and imports/ast_nodes are empty.
Supported languages for symbol extraction: Rust, TypeScript, JavaScript, Python, Go.
Symbol kinds: function, struct, enum, trait, type, const, static, mod, macro, class, interface (varies by language).
devsql "<query>" or devsql <subcommand> <args>Note: history.timestamp is in milliseconds. Use datetime(timestamp/1000, 'unixepoch') to convert.
