For DeepSeek Harness (DSH).

Dispatch subagents in DeepSeek Harness: pick model, reasoning effort, and tool scope per task; save common combos as named profiles for reuse. Built-in safety checks, cost estimation with savings analysis, and a full decision ledger.

Why this plugin

	Built-in subagent	dsh-subagent-profile
Per-subtask model / preset	✅ optional provider / model / reasoning_effort (after enabling model selection)	✅ one profile bundles preset + model + effort + tool scope + budget; overridable per call
Reusable named setups	❌	✅ profiles
Tool-scope narrowing	❌	✅ whitelist ∩ parent, run_code always removed
Safety checks	❌	✅ whitelist / cost / intersection / approval / budget, all recorded
Cost visibility	❌	✅ per-dispatch estimate + savings comparison
Decision ledger	❌	✅ full trace: request vs. effective, checks, execution, settlement
GUI management	❌	✅ settings page + per-session ledger tab
Performance-based suggestions	❌	✅ confirm to apply, undo anytime
Official model-selection interplay	✅ enforced natively once enabled	✅ dispatch follows the same whitelist (out-of-range routes are rejected)

Installation

dsh plugin --profile web add dsh-subagent-profile        # published package
dsh plugin --profile web add ./dsh-subagent-profile      # from a local checkout

Restart dsh web. This is a standard bundle plugin: it provides the dispatch tool, the profile provider, the subagent-profiles service, the /subagent-profiles/* loopback management routes, the settings page (「子 Agent 方案」), the per-session ledger tab, and the dispatch tool-call card in the web GUI. On startup it also self-installs an agent preset — orchestrator-v2 (「编排者模式 V2」) — pick it in the new-session preset picker. The sync is idempotent and re-runs on every startup, so upgrading the plugin updates the preset.

Usage

1. Configure sub-agent profiles

Profiles are managed in the settings page — each one bundles preset + model + reasoning effort + tool scope (and optionally a persona), and can be enabled, disabled, edited, or reset individually. Two built-ins ship:

Profile	Purpose
swap-standard	switch the child to the full standard coding toolkit
researcher	deep reasoning off, search-only tools

Profiles live in ~/.dsh/subagent-profiles.json and take effect immediately (edits are made from the settings page).

2. Dispatch per subtask — the dispatch tool

dispatch(
  profile: "researcher",        // preset + model + reasoning effort + tool scope
  prompt: "Survey the DSH plugin ecosystem and compare direct competitors",
  run_in_background: true
)

3. Review in the decision ledger

Every session has a ledger tab that records each dispatch decision: what the parent saw and requested, what actually took effect (with ignored-request highlights), which tools were removed and why, how execution went (including stalls and parent interventions), and what it cost. Safety-check failures are surfaced with fix directions.

Safety model

Delegation never lets a subagent gain more power than you already have — this is the default, with no configuration:

• Tools only shrink. A child's tool set is the intersection of the profile's tools and the parent's tools, and run_code is always removed.
• Approval is never bypassed. Delegation does not waive the host's approval requirements; operations that need approval are rejected automatically.
• Cost is capped. Model, reasoning effort, tokens, and recursion depth are all bounded; out-of-range values fail loudly instead of silently downgrading.
• An escape hatch, explicitly. Non-official presets can be allowed per-preset (default off, each allowance audited).

Observability & notifications

• Live status. Background dispatches show live phase badges (start / gate / create / running / settled), driven by host job events with polling fallback.
• Reminder center. Urgent events (escape-hatch allowances, audit degradation, budget anomalies) raise a persistent badge; the notification center keeps every reminder with full context — parent session, child session, task summary, and outcome — plus one-click jumps to the related sessions. Normal orchestration events (e.g. a parent not adopting a child's result) are recorded in the audit ledger without interrupting you.
• Dispatch suggestions. Based on historical dispatch statistics, the plugin can inject read-only optimization hints for the parent agent (e.g. "this profile has a low recent success rate, consider switching") — hints only, nothing is changed automatically.
• Subagent header badge. Child sessions show a compact summary badge (e.g. 继承父会话 · 前台 — "inherits the parent session, foreground"); hover for the full detail (model / effort / preset / mode / origin).

Data

• ~/.dsh/subagent-profiles.json — the profile registry (edited from the settings page).
• ~/.dsh/subagent-profiles.state.json — the plugin's enable/disable switch (default enabled).
• ~/.dsh/subagent-profiles.failed-traces.json — the failure ledger (dispatch failure traces).
• ~/.dsh/subagent-evolution/ — the decision ledger and statistics:
  • dispatch.jsonl — per-dispatch decision records (no prompt content).
  • summaries.json — aggregated per-profile statistics (versioned, rebuilt on corruption).
  • adopted-state.json — adoption verdict state for child results (cross-restart).
  • reminders.json — reminder store (one reminder = one audit record).
• ~/.dsh/.agent-presets/orchestrator-v2/ — the self-installed orchestrator-v2 agent preset (synced from the bundled presets/orchestrator-v2/ on every startup).

DSH_HOME is respected and defaults to ~/.dsh. Uninstalling the plugin removes the data files above and the self-installed orchestrator-v2 preset directory (other plugins' presets are left untouched); re-installing or re-launching re-syncs the preset and regenerates the data files.

Known limitations

• Background dispatch requires @deepseek-ai/dsh-jobs and @deepseek-ai/dsh-tool-jobs to be loaded; otherwise it fails with "dispatch: 后台派发不可用：缺少 jobs 服务".
• Continuable mode goes through the DSH standard composition path, so the preset swap and reasoningEffort are ignored (the child inherits the parent preset at the default reasoning effort).
• Continuable follow-ups are delivered through the official send_message channel (the plugin drives the child via the official child handle).
• Official model selection is a web-line feature: the session policy for the built-in subagent tools ships with the web app and is not available in headless deployments. In production it is off by default and must be enabled before it takes effect.
• Who decides the child's final tool set depends on the mode:
  • Continuable: narrowed by this plugin up front — the child's allow = (parent tool set − run_code − deny) ∩ allow. Assumption: continuable inherits the parent preset, so the child's tool set ≈ the parent's; if dsh's behavior changes so the two differ (e.g. a future preset swap composing a different tool set), tool narrowing fails with a hard error (conservatively safe — never silently granting more), to be replaced with a true parent ∩ child intersection once dsh provides an official seam.
  • One-shot: decided by dsh; the plugin cannot read the final restricted result and the card reports "tools are finally granted by the system".
• Cost figures are estimates: computed from an average per-dispatch price (measured once per model); fine-grained per-token pricing is on the roadmap. The UI labels estimates as such and shows a note when the sample size is small.
