geml vs context-mode
geml: GEML is an Agent-Native markup format and protocol designed for collaborative document creation and editing between people and AI agents. It addresses critical issues like context bloat and data fragmentation by providing precise, addressable, and verifiable block-level operations.; context-mode: Every tool call in an MCP (Model-Controller-Program) environment dumps raw data into the context window, quickly consuming space and causing the agent to lose track of ongoing tasks. Context Mode is an MCP server that tackles this by sandboxing tool outputs to significantly reduce context usage, tracking session events in SQLite for continuity, and promoting 'think in code' to minimize data processing within the LLM.

When to choose:
- Your sessions fill up with tool output such as Playwright snapshots, GitHub issue lists or logs.
- You want work state (edits, git operations, tasks, decisions) to survive context compaction without being dumped back into the window.
- You use a hook-capable agent, where tool routing happens automatically.
When to skip:
- You need an OSI open-source licence: it uses the Elastic License 2.0, which restricts uses such as offering it as a managed service.
- Your sessions are short and rarely hit the context limit.
- You do not want hooks changing how your agent's tools behave.

Features
geml01AST-level structured operations: Enables precise block-level create/read/update/delete, replacing whole-file rewrites with partial, idempotent updates.
02Low-token reads and writes: Significantly reduces prompt-token cost by allowing agents to operate on specific, addressable blocks, improving model throughput and lowering inference cost.
03Single source of truth with modular references: Supports native cross-document and cross-fragment references, ensuring changes at the source propagate everywhere and eliminate version skew.
04Robust two-way reads and writes: Utilizes a simple, uniform block structure well-suited for LLM generation, complemented by a strict validator providing precise error feedback.
context-mode01Context Saving: Sandbox tools keep raw data out of the context window, achieving up to 98% reduction.
02Session Continuity: Tracks every file edit, git operation, task, and user decision in SQLite for seamless session resume.
03Think in Code: Promotes LLMs to program analysis, not compute it, saving 100x context by logging only results.
04Batch Execution & Search: Run multiple commands/queries in one call with tools like `ctx_batch_execute`.
05Advanced Knowledge Base: Uses SQLite FTS5 with BM25 ranking, smart snippets, and TTL cache for efficient information retrieval.

Use Cases
geml↳Enabling seamless, high-frequency collaboration between human writers and AI agents on shared documents.
↳Optimizing LLM context window usage and reducing token costs by allowing agents to operate on specific document blocks rather than entire files.
↳Maintaining document integrity, preventing semantic drift, and enabling traceability and atomic rollbacks in multi-round agent-driven document generation and editing.
↳Generating and dynamically visualizing code call graphs from entire codebases for debugging, impact analysis, and understanding code structure.
context-mode↳Deep repository research and analysis (e.g., architecture, contributors, issues)
↳Analyze Git history to identify top contributors, commit frequency, and most changed files
↳Efficiently process large JSON APIs, web pages, or logs without flooding the context window
