claude-code-log is a Python command-line tool that turns Claude Code transcript files into readable HTML or Markdown logs. It helps people browse individual sessions or complete project archives, with options for interactive browsing and live updates. The catalogue add-ons extend its use as an agent-related workflow.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01407 | $0.01407 |
| Opus 5.5 | $0.00563 | $0.00563 |
| Sonnet 5.5 | $0.00281 | $0.00281 |
| Haiku 4.5 | $0.00141 | $0.00141 |
Grade A, and why
claude-code-log CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Code Log
A Python CLI tool that converts Claude Code transcript JSONL files into readable HTML format.
Project Overview
This tool processes Claude Code transcript files (stored as JSONL) and generates clean, minimalist HTML pages with comprehensive session navigation and token usage tracking. It's designed to create a readable log of your Claude interactions with rich metadata and easy navigation.
Key Features
- Interactive TUI (Terminal User Interface): Browse and manage Claude Code sessions with real-time navigation, summaries, and quick actions for HTML export and session resuming
- Project Hierarchy Processing: Process entire
~/.claude/projects/directory with linked index page - Individual Session Files: Generate separate HTML files for each session with navigation links
- Session Navigation: Interactive table of contents with session summaries and quick navigation
- Token Usage Tracking: Display token consumption for individual messages and session totals
- Runtime Message Filtering: JavaScript-powered filtering to show/hide message types
- Interactive Timeline: vis-timeline visualization with click-to-scroll navigation
- Date Range Filtering: Filter messages using natural language (e.g., "today", "yesterday")
- Markdown Rendering: Server-side markdown with syntax highlighting using wenmode

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
