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

cache-sentinel is a DeepSeek Harness plugin designed to prevent unexpected token billing caused by sending follow-up prompts into stale sessions after prompt cache expiry. Operating in configurable block, archive, or combined modes, it intercepts user input in expired sessions, surfaces warning banners in supported web interfaces, and provides /unlock and /sentinel commands to control execution and session persistence.

Key Capabilities

Evaluates elapsed idle time since the last model response using agent/pre-step hooks
Blocks user message sends to expired sessions to prevent uncached full-context billing while allowing ongoing tool execution and subagent runs
Automatically archives inactive sessions after a configurable duration to keep workspace history clean
Injects pre-send warning banners and one-time /unlock controls into compatible web interfaces
Provides /sentinel and /unlock chat commands along with a REST status API endpoint

Useful For

Preventing expensive token re-evaluations when resuming long-dormant conversational threads
Auto-archiving abandoned or stale sessions in web and desktop profiles
Enforcing explicit confirmation (/unlock) before paying full uncached context rates on older chats

Who It Fits

Cost-conscious developers and teams running long-running DeepSeek Harness agents
DeepSeek Harness web and desktop UI users who frequently switch between multiple sessions

Documented Limitations

Requires profiles bundling @deepseek-ai/dsh-web-app (such as web or desktop); will not activate on headless or acp profiles
Because DSH's workspace.json is replaced on write, running archive mode simultaneously across multiple active profiles may cause archive state conflicts
Alternative frontends like M3E do not load custom plugin client bundles, disabling pre-send warning banners
Actions outside direct user chat sends (such as /goal creations or direct questions) bypass input blocking
