CodeRecoder: Instructions file for Claude Code

CLAUDE.md

CodeRecoder CLAUDE.md is an instructions file for Claude Code from snow-wind-001/CodeRecoder. It costs 737 tokens per session, scanned A, original, MIT.

A Claude Code instruction file for CodeRecoder, an AI-assisted system for saving file and project versions and detecting changes. It describes the architecture, development commands, and how the project stores data for each active project.

In plain words
What is it for?
Use it when developing, building, running, or reviewing CodeRecoder and its project, file-snapshot, history, data, or AI-analysis components.
Why use it?
Without project-specific guidance, an assistant may misunderstand the manager-based design or where snapshots and configuration are stored.

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is snow-wind-001/CodeRecoder's own configuration. It tells Claude Code how to work on CodeRecoder itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything CodeRecoder configures →

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.

Security

Grade A, and why

CodeRecoder 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.

Guidance for Claude Code when changing CodeRecoder.

Product Contract

CodeRecoder is a code backup service, not a Git implementation or an AI analysis service. The production MCP tool surface is registered in src/index.ts. Do not re-expose the legacy file-history, simulated Serena, old GUI tools, or incremental-chain tools through MCP. The Vue/Electron app under desktop/ is an independent local client and must keep using the production backup engine.

An active project belongs only to the current MCP process. Never persist or restore a globally active project. Project source must not require instrumentation; use storageRoot when backup metadata must remain outside the protected tree.

Architecture

  • BackupManager creates complete logical snapshots and owns manifests, SHA-256 verification, atomic indexes, retention, locks, restore tokens, safety backups, rollback, and startup recovery.
  • AutoCheckpointManager watches the active tree, coalesces events, queues writes during backup, and performs periodic reconciliation.
  • CodeRecoderServer exposes validated MCP tools, annotations, structured output, process-local activation, and watcher coordination.
  • ProjectSessionRegistry owns isolated desktop sessions; each ProjectSession has its own backup manager, watcher, queue, recovery state, and Serena sidecar. Preload exposes only typed, allowlisted, project-scoped IPC, and renderer code has no Node access.
  • Older managers still compile for migration reference but are not production entry points. Their optional AI providers must remain explicitly unavailable unless a real transport and health check are implemented.

Non-Negotiable Restore Invariants

  1. preview_project_restore must verify the target and bind a short-lived token to the current tree hash, project, snapshot, and restore mode.
  2. restore_project_snapshot must reject expired, reused, mismatched, or stale tokens.
  3. A verified protected pre-restore snapshot and durable recovery journal must exist before source mutation.
  4. Automatic monitoring must pause and discard restore-generated events.
  5. Success requires byte/type/mode verification; failure requires rollback. Leave the recovery journal in place if rollback cannot be verified.
  6. Exact restore may remove only scanned, non-excluded paths. Never recursively delete an ignored non-empty directory.

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.
