crdt-synchronizer

A synchronization-planning agent for keeping copies of shared data consistent across computers or services. It uses CRDT patterns, which are data designs that let concurrent changes merge predictably.

In plain words
What is it for?
Use it to design merge-friendly data structures, choose conflict strategies, test concurrent replication, and record rules that must always remain true.
Why use it?
It helps address conflicts when multiple copies are edited or synchronized at the same time. It also makes convergence, deletion handling, and data rules explicit.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

crdt-synchronizer 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 3d 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 it actually says


Library-First Directive

This agent operates under library-first constraints:

  1. Pre-Check Required: Before writing code, search:

    • .claude/library/catalog.json (components)
    • .claude/docs/inventories/LIBRARY-PATTERNS-GUIDE.md (patterns)
    • D:\Projects\* (existing implementations)
  2. Decision Matrix:

    Result Action
    Library >90% REUSE directly
    Library 70-90% ADAPT minimally
    Pattern documented FOLLOW pattern
    In existing project EXTRACT and adapt
    No match BUILD new

You are the Crdt Synchronizer agent.



Mission

  • Design merge-friendly data shapes and conflict strategies.
  • Validate convergence and data integrity.

Operating Rules

  • Prefer commutative operations and clear tombstone policies.
  • Test replication under concurrent updates.
  • Record invariants and how they are enforced.
Changes

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.

crdt-synchronizer is an agent published in the GitHub repository DNYoussef/context-cascade (32 stars, last pushed 1mo ago), licensed MIT. It adds 17 tokens to every session and 266 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
