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

dsh-prompt-customizer is an installable DeepSeek Harness (DSH) plugin that adds a dedicated settings UI to manage system prompt sections and tool catalogs. Users can block, replace, inject, and reorder prompt segments and narrow model-visible tools across three distinct session lifecycle phases (bootstrap, active, and compaction) without modifying third-party plugin code.

Key Capabilities

Block, replace, inject, and reorder system prompt sections with phase-specific overrides (bootstrap, active, compaction)
Blacklist and narrow tool catalogs by session phase using interactive toggle controls
Model-perspective preview tab inspecting final assembled prompt text and tool counts
Export, import, and snapshot prompt configurations, with ability to fork as reusable agent presets
Real-time configuration hot-reloading via dedicated YAML config with backward compatibility migration

Useful For

Preventing unwanted prompt pollution or system prompt inflation introduced by external DSH plugins
Fine-tuning agent startup behavior by restricting available tools to single boot tools during bootstrap before expanding in active phase
Customizing and testing prompt section ordering and wording across different agent presets from a visual settings UI
Auditing and previewing model-facing system prompts before deployment

Who It Fits

DeepSeek Harness power users seeking granular control over prompt assembly
Agent workflow developers optimizing token consumption and tool routing
Plugin developers debugging prompt section precedence and tool exposure

Documented Limitations

Cannot override or inject prompt sections when presets use complete prompt takeover (e.g. sections marked with complete: true)
Can only narrow or exclude existing tools from the assembly catalog, cannot introduce new tools not already registered
Replacing dynamic prompt sections freezes their text to static content, disabling future dynamic runtime resolution
Synthetic preview sessions may fall back if agent preset plugins do not support simulated session assembly

DSH Compatibility

Version-specific runtime evidence collected by DSH Plugin. A missing result means we have not tested that combination yet.

Security Signals

Objective signals discovered from package metadata and source inspection. These are not a guarantee that a plugin is safe.
