MAMA vs context-mode
MAMA: MAMA OS provides local operating memory for AI agents, enabling them to connect diverse data sources like chats and documents into a searchable memory substrate. It allows agents to understand context, cite evidence, track decision evolution, and operate within defined boundaries to produce better briefings and actions.; 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
MAMA01Enables AI agents to read the board, cite evidence, and operate within explicit boundaries using local operating memory.
02Integrates diverse data sources like chats, documents, decisions, and work logs into a unified local memory substrate.
03Builds a knowledge graph that tracks decision evolution, including relationships like 'supersedes', 'builds on', and 'debates'.
04Features strict and balanced search modes that reject vector-only noise unless confirmed by lexical, entity, raw, or seed evidence.
05Ensures agent security through signed runtime envelopes, scope boundaries, and destination limits enforced before tool calls.
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
MAMA↳Assess Project Risk: An agent can assess project risk by synthesizing information from emails, Slack, PR status, and QA checklists.
↳Generate Cited Reports: Produce detailed situation reports and briefings for humans, explicitly citing evidence and separating judgment from inference.
↳Automate Workflow Triggers: An agent authors its own triggers from recurring situations, recalling relevant memory and folding everything into owner situation reports.
↳Manage Company Memory Twin: Maintain an append-only company memory twin that agents can inspect, simulate, and cite, preserving raw evidence and its evolution.
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
