Plugin Overview & Capabilities

AI-assisted organization based on the public repository snapshot. The content must be grounded in source evidence and does not replace compatibility or security verification.

source-grounded

Context Guardian is a context management and compaction plugin bundle designed for DeepSeek Harness and local LLMs. It monitors conversation token limits, performs deterministic seq-pointer-preserving compaction before context limits crash the session, and archives evicted turns into disk-backed spans. Equipped with companion model-facing recall and search capabilities, it enables agents to retrieve past details and pins vital facts across long-running sessions without dropping critical history.

Key Capabilities

Automatic conversation compaction triggered at configurable context window thresholds
Deterministic fallback checkpointing preserving sequential pointers when model summarization fails or overflows
Disk-backed span archival storing raw conversation turns losslessly for future lookup
Model-accessible recall and search tools to retrieve compacted details on demand
Automatic fact pinning and stale recall to prevent hallucination of previously stated requirements
Session handoff generation in JSON and Markdown formats for multi-agent continuation

Useful For

Preventing context window overflow errors in long local agentic development sessions
Archiving and retrieving past instructions, codenames, and decisions in multi-turn dialogues
Stabilizing agent preset memory when running local Ollama, LM Studio, or vLLM models

Who It Fits

DeepSeek Harness agent builders working with constrained local context windows
Developers orchestrating multi-step autonomous tasks using local LLMs
Engineers requiring fail-open, verifiable context compaction and audit trails

Documented Limitations

Character-to-token estimation heuristic (3.5 characters per token) can undercount dense JSON or CJK characters without calibration
Does not compress raw tool schema definitions directly, requiring tool filtering plugins for high-volume MCP environments
Subject to DeepSeek Harness pre-1.0 compaction API changes between alpha releases
