Enables deterministic linting of locale files across JSON, Laravel PHP, gettext, and YAML, with no LLM or network, verifying translations for missing keys, placeholders, plural forms, glossary consistency, and stale entries.

Accurately counts characters, bytes, and manuscript paper based on Unicode grapheme clusters, and provides deterministic feedback to help AI meet exact length limits for self-introductions or school records.

MCP server providing context usage estimation, conversation compaction, and durable semantic memory via local embeddings and SQLite.

Provides AI agents with calendar access and syncing capabilities through the Model Context Protocol.

Remote MCP server that exposes context-keeper's rationale store (decisions, pipelines, constraints) over Streamable HTTP, deployable on Cloudflare Workers and usable as a claude.ai custom connector.

Serves as a guardian of development knowledge, providing AI assistants with curated access to latest documentation and best practices.

Provides persistent context management for Claude AI coding assistants, allowing you to save and restore conversation context, create checkpoints, and organize information across sessions to prevent losing important work history and decisions during long coding sessions.

Enables agents to capture and validate market research including theses, entry conditions, targets, and invalidation, and bundle them into Warper Keeper bundles.
