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-fast is a read-only performance diagnostics plugin for DeepSeek Harness. It passively observes the session event stream outside the model hot path to report session load and restore timing, tool spill-hit counts, compaction activity, context-injection volumes across prompt components, and LLM cache hit rates via the /fast command and the fast_report tool.

Key Capabilities

  • Measures session open and restore publication-to-first-request latency
  • Tracks tool output spill counts from session artifacts
  • Monitors compaction frequency, triggers (manual vs automatic), and shadowed token count
  • Calculates token shares for system prompts, tool schemas, and conversation surfaces
  • Derives LLM cache hit rates from token usage statistics
  • Surfaces session diagnostics via the /fast slash command and structured fast_report tool
  • Asynchronously samples metrics with zero overhead on the model execution path

Useful For

  • Diagnosing high latency or sluggish restore operations in long-running DSH sessions
  • Auditing context budget consumption by skills, AGENTS.md, and tool schemas
  • Verifying prompt caching efficiency across LLM requests
  • Inspecting compaction triggers and spilled tool call outputs

Who It Fits

  • DeepSeek Harness plugin and agent developers
  • Engineers optimizing context window usage and model prompt caching
  • System administrators monitoring agent runtime performance

Documented Limitations

  • Persists metrics to the dsh_fast storage domain rather than direct session events
  • Spill detection relies on durable spill notice text heuristics
  • System prompt components (AGENTS.md, skills, persona) are tracked as one aggregated bucket
  • Session load timing measures publication-to-first-request and does not observe disk reads prior to session creation

DSH Compatibility

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