What is claude-file-recovery CLAUDE.md?

Instructions for recovering files that Claude Code created or changed from its JSONL session transcripts, which are structured log files. The related tool can list recoverable files, extract them, or open them in a text interface.

Listing recovered files, filtering them by filename pattern, exporting selected files to disk, and browsing recovery data interactively.

Files may be recoverable even after they are no longer present in the working directory. These instructions explain how to install and use the recovery tool.

Token cost

What it costs to keep this loaded

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	$0.00777	$0.00777
Opus 5	$0.00388	$0.00388
Sonnet 5	$0.00155	$0.00155
Haiku 4.5	$0.00078	$0.00078

Security

Grade A, and why

claude-file-recovery 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 12d 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.

What This Project Does

claude-file-recovery is a CLI/TUI tool that recovers files created and modified by Claude Code from its JSONL session transcripts (~/.claude/projects/). It parses Write, Edit, and Read tool-use entries, reconstructs file contents by replaying operations in order, and lets users browse/extract them.

Commands

# Install in development mode (uses uv + hatch)
uv pip install -e .

# Run the TUI (default command)
claude-file-recovery
claude-file-recovery --claude-dir ./claude-backup

# List recoverable files
claude-file-recovery list-files
claude-file-recovery list-files --filter '*.ts' --csv

# Extract files to disk
claude-file-recovery extract-files --output ./recovered --filter '*.py'

There are no tests yet. No linter or formatter is configured.

Architecture

Entry point: src/claude_file_recovery/cli.py — Typer app with three commands: list-files, extract-files, and tui (also the default when invoked without a subcommand).

Core pipeline (src/claude_file_recovery/core/):

scanner.py — Discovers JSONL files under projects/<slug>/, parses them line-by-line with orjson, and extracts FileOperation objects from assistant entries (Write/Edit/Read tool_use blocks) and user entries (toolUseResult enrichment). Uses ThreadPoolExecutor to scan sessions in parallel. The two-pass correlation works via tool_use_id: tool_use blocks in assistant messages create pending ops, then toolUseResult in user messages enriches them with actual content and originalFile.
reconstructor.py — Replays a RecoverableFile's operations in chronological order to rebuild content. Write/Read ops set content directly; Edit ops apply string replacements. The originalFile field on Edit ops serves as a fallback base when no prior Write/Read exists.
models.py — OpType enum (WRITE_CREATE, WRITE_UPDATE, EDIT, READ, FILE_HISTORY), FileOperation dataclass (content fields populated during scanning), RecoverableFile dataclass (groups ops by absolute file path, provides has_full_content and latest_timestamp properties).

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.
