context-mode vs projectmem
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.; projectmem: projectmem is an open-source, local-first memory and judgment layer for AI coding agents, designed to capture persistent records of project development, including issues, attempts, fixes, and decisions. It aims to make AI experienced, preventing repetition of past failures and significantly reducing token usage by providing distilled context.

TL;DR
context-modeMemory & Context · ★ 31.8k
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
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.
projectmem01Pre-Commit Warnings: Warns developers before committing if they're repeating failed approaches, modifying high-churn files, or touching unresolved issues.
02Local-First and 100% Private: All memory and data reside locally in a `.projectmem/` directory with no cloud, accounts, or telemetry.
03Global Dashboard: Provides a unified view of all `pjm init`-ed projects, showing grades, issues, savings, and a 'needs attention' list, aggregated at read-time.
04Code Structure + Judgment: Overlays failure heat from the event log directly onto the codebase's import graph, highlighting files with repeated failed attempts.
05Smart Context Injection & Token Efficiency: Distills raw event logs into compact, AI-readable summaries and provides token-budgeted memory blocks, significantly reducing token cost.

Use Cases
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
projectmem↳Preventing AI agents from repeating past debugging attempts or failed architectural approaches.
↳Improving AI agent efficiency and reducing token costs by providing distilled, context-aware project memory instead of re-reading raw files.
↳Visualizing project development history, including issues, fixes, and decisions, to understand codebase evolution and identify problem areas.
↳Onboarding new developers or bringing AI agents up to speed on a project quickly by injecting pre-existing project knowledge and decisions.
↳Providing a persistent, auditable record of AI agent interactions and learning within a project.
