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 DeepSeek Harness plugin that observes session events to report load timing, spill activity, compaction, context-injection volume, and LLM cache usage. It installs as a Cordis profile bundle and persists bounded per-session metric history in a storage domain.

Key Capabilities

Reports session publication-to-first-request timing, distinguishing fresh opens from restores.
Tracks heuristic spill-hit counts from durable spill notices.
Summarizes compaction counts, manual versus automatic triggers, and shadowed tokens.
Measures system-prompt, tool-schema, and conversation-surface token volume and shares.
Aggregates provider usage into LLM cache hit-rate metrics.
Provides threshold-driven optimization suggestions.
Exposes reports through the /fast slash command and fast_report structured model tool.
Samples active sessions asynchronously and retains bounded per-session history.

Useful For

Diagnose session startup or restore latency visible after session publication.
Identify large context contributors such as system prompts, tool schemas, and conversation surface.
Review compaction frequency and shadowed-token volume.
Assess provider-reported LLM cache utilization.
Give an agent structured performance-report data through fast_report.

Who It Fits

DeepSeek Harness users investigating session performance and context consumption.
Plugin and workflow developers tuning prompts, skills, tool schemas, or compaction behavior.
Teams needing read-only session diagnostic reports within DeepSeek Harness.

Documented Limitations

Compatible with DeepSeek Harness 0.1.0-rc.8 and specified peer dependency ranges.
Requires Node.js ^22.19.0 or >=24.0.0 and uses ESM.
Load timing excludes disk-read time before session/created publication.
Spill detection is heuristic and relies on a durable spill-notice format.
AGENTS.md, skills, and persona token usage are reported as one system-prompt bucket rather than separate sections.
Metrics are persisted in the dsh_fast storage domain rather than custom fast/* session events.

DSH Compatibility

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

Not tested yetNo runtime compatibility tests have been published yet.

Security Signals

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