dsh-subagent-profile

Subagent dispatch, profiled — the right agent for the right task (preset / model / reasoning effort)

For DeepSeek Harness (DSH).

Thinking, Fast and Slow: System 1 is fast and cheap, System 2 is slow and careful. The built-in subagent gives every subtask the same brain as its parent — no way to tell them apart. dsh-subagent-profile lets you pick per subtask: research with a fast brain, deep work with a careful one, saved as named profiles.

Why this plugin

• Per-subtask control over the child's brain. dispatch sets, per subtask: which preset (composition), which model, which reasoning effort, which tools, and the token cap. A research subtask and a coding subtask can run with completely different setups — something the plain subagent tool can't do (it only inherits the parent).
• Named, reusable profiles. A profile is one bundle of preset + model + reasoning effort + tool scope + persona. Save "research" as researcher (reasoning off, search-only tools) and dispatch with dispatch(profile="researcher"); two built-ins ship (swap-standard = full standard coding toolkit, researcher), and you can add/edit/remove your own in the settings page.
• Fully observable. Every result reports the effective profile / preset / model / reasoning effort; logs are tagged [dsh-subagent-profile].

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」), and the dispatch tool-call card in the web GUI. On startup it also self-installs an agent preset — orchestrator (「编排者模式」) — 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:

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
)

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 always "never". A child cannot widen its own permissions; 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.

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/.agent-presets/orchestrator/ — the self-installed orchestrator agent preset (synced from the bundled presets/orchestrator/ on every startup).

DSH_HOME is respected and defaults to ~/.dsh. Uninstalling the plugin removes the three data files above and the self-installed orchestrator 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 one-shot 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 tool gate is a plugin-side mitigation: the child's allow is pre-computed as a closed set — parent tool set − run_code − deny, then intersected with allow. Assumption: continuable inherits the parent preset, so the child's tool set ≈ the parent's. Failure condition: any host behavior change that makes the child's tool set differ from the parent's (not only preset swap — e.g. a future preset swap, composing a different tool set) means the parent set can contain tools the child does not have, so tools.restrict throws "unknown tool" and this mitigation automatically degrades to fail-loud (conservatively safe); it must then be replaced with a true parent ∩ child intersection once the upstream provides a provider guard seam.
