dsh-explain

Quick start · Watch the full demo · Privacy model · Reproduce the recording

dsh-explain is a learning-mode plugin for DeepSeek Harness. It turns useful concepts from completed work into structured explanations, schedules lightweight reviews, and lets you inspect or correct what it learns about you.

The primary agent stays untouched. Explain uses its own model calls, scheduler, context, and local SQLite database.

The 28-second preview runs against real assembled DSH Web 0.1.2-rc.1 with deterministic, private fixture data. Watch the higher-quality MP4 or read the recording contract.

Capture	Review	Adapt
Turn a finalized answer or selected text into an editable /explain draft. Nothing submits automatically.	Revisit due concepts through recall, application, and distinction questions.	Inspect explanation preferences and topic familiarity, then correct or forget an inference.

Quick start

The current development and installation baseline is DSH 0.1.5-alpha.2, available on npm as of 2026-09-10. npm latest / next still point to 0.1.2-rc.1, which remains supported alongside 0.1.3-alpha.1, 0.1.3-alpha.2, and 0.1.5-alpha.1. Pin the version explicitly; see the compatibility contract for exact source revisions and verification.

Open Settings → Learning, choose an auxiliary provider and model, enable learning mode, and save. Explain observes only future completed top-level turns; it does not scan existing history.

Git-hosted plugins build during installation. If pnpm requests build approval, add the printed dsh-explain entry to the profile's pnpm-workspace.yaml, then repeat the install command. For automated runs that should not open a browser, start DSH with --no-open.

The latest tagged Explain release is v0.2.0; v0.3.0 has not been published. Installing from GitHub uses the current main branch with compatibility for all five versions listed below.

Start from the work itself

Entry point	What happens
/explain <request>	Requests an explanation using the current session as bounded source context.
Explain selected text	Creates an editable /explain --selection … draft from visible text.
Learn from this answer	Creates an editable draft tied to the exact finalized assistant turn.
Automatic evaluation	May add one useful explanation after an eligible turn, within your configured budget.
/review	Opens or resumes a local review round in the Learning tab.

Each explanation answers three practical questions: What is it? Why does it matter here? What is the common pitfall? Choose Got it to close the card, or Not yet for a different explanation.

Review, then correct the model

Concepts marked Got it enter a local spaced-review schedule. Learning → Today's review selects up to three due concepts. Each concept advances from recall to application to distinction after successful answers; an unsuccessful answer repeats that skill next time. The auxiliary model evaluates each answer as Mastered, Partial, or Forgotten and schedules the next review at a deterministic interval. Partial or forgotten concepts are treated as learning again and can receive a new explanation; an active explanation pauses that concept's quiz.

Learning → Learning overview exposes the current judgments about explanation length, structure, examples, terminology, and topic familiarity—with confidence and source links. You can correct an inference, forget it, or set an explicit preference. Precedence is fixed and visible: explicit preference → user correction → model inference.

One learning thread, many sessions

• Every $DSH_HOME owns exactly one Explain learning thread; resumes and forks never copy it.
• Every source session has at most one explanation awaiting feedback.
• One global scheduler serializes explanations, reviews, autonomous evaluation, rephrases, and compaction.
• Autonomous evaluation has a persistent rolling 24-hour budget, configurable in Settings.
• Rephrasing still works if a source session is later deleted because only a bounded source summary is retained.

Local-first by design

Data	Behavior
Learning thread	Stored in $DSH_HOME/dsh-explain/v1/thread.sqlite.
Enablement and model settings	Stored through DSH settings in $DSH_HOME/settings.yaml.
Source material	Reduced to bounded capsules; rephrasing retains at most a 2,000-character restricted summary.
Global learning context	Sent with bounded source text to the configured auxiliary provider. Local storage does not imply offline model inference.
Export	A versioned local backup excludes private source summaries and filters common credential/path formats in public text. Arbitrary private prose may remain; review before sharing.
Clear	A typed CLEAR confirmation atomically removes learned content while preserving runtime settings and the active budget window.

Explain uses first-party DSH conversation, composer, assistant-action, and settings extension points. It does not require patches to DSH or other plugins.

Compatibility and verification

Check	Current result
DSH compatibility	0.1.5-alpha.2 published packages; 0.1.2-rc.1, 0.1.3-alpha.1, 0.1.3-alpha.2, 0.1.5-alpha.1, and 0.1.5-alpha.2 assembled source
Unit and integration	80 tests on each source version
Assembled DSH Web	7 scenarios per source version
Explain-owned shortcuts	3 M6 scenarios
Production package	Build and pack dry-run

See the acceptance matrix for coverage and PR #16 for the earlier real-model workflow evidence. DSH remains a developer preview; Explain follows its current public API line instead of retaining compatibility layers for private-preview packages.

Local development

The default development install uses published 0.1.5-alpha.2 API packages, with a version-scoped repair for their missing store runtime dependencies. Assembled-Web tests accept a built DSH 0.1.2-rc.1, 0.1.3-alpha.1, 0.1.3-alpha.2, 0.1.5-alpha.1, or 0.1.5-alpha.2 checkout. The existing demo recording remains on rc.1:

pnpm install
DSH_SOURCE_DIR=/absolute/path/to/dsh pnpm dsh:link
DSH_SOURCE_DIR=/absolute/path/to/dsh pnpm dsh:link:check
pnpm typecheck
pnpm test
DSH_SOURCE_DIR=/absolute/path/to/dsh pnpm test:web
DSH_SOURCE_DIR=/absolute/path/to/dsh pnpm test:m6
pnpm build

Install this checkout directly for manual development:
