Two-phase DeepSeek Harness preset: Minimal-aligned bootstrap, then full Standard tools (Project2 98/99)

DeepSeek Harness

dsh-anchored-standard is an experimental DeepSeek Harness agent preset that uses a two-phase approach to optimize AI agent performance: it starts sessions with a minimal tool catalog (bash and str_replace_editor) to anchor the model's reasoning trajectory, then promotes to a full Standard toolset after the first durable interaction. Originally validated on DeepSeek V4 Pro with Project2 scores of 98-99, the project is now frozen following the model's retirement. The preset includes multiple variants (zero-anchored, whoami, eternal-minimal, wire-think, combo-anchored) and ships with unified injection control, prefab session templates, and a comprehensive plugin architecture.

Key Features

Two-phase trajectory anchoring: minimal bootstrap (bash + str_replace_editor) followed by promotion to resident catalog with discovery tools
Context-gate plugin suppresses auto-injected context during bootstrap phase for clean first-request conditions
Multiple variants: zero-tool anchor turn, whoami self-introduction, eternal-minimal with dshx gateway, wire-level tool_choice control
Prefab mode with bundled session templates for instant deployment without warm-up
Unified injection control at harness-level paths (context-gate) with resume-safe phase derivation from durable events
Discovery tools (dev_tool_search, skill_search, skill_load) unlock heavier Standard tools on-demand without trajectory drift
Combo package combining think/execute split, deliberation depth gate, and COT drip mechanisms as independent rows
Self-contained mode directories installable separately with materialized shared plugins

Use Cases

  • 01Optimizing DeepSeek-based coding agents for Project2-style software engineering benchmarks
  • 02Preserving minimal-trajectory reasoning quality while retaining access to full Standard toolsets
  • 03Running controlled experiments on AI agent tool-surface conditioning and trajectory anchoring
  • 04Deploying pre-warmed agent sessions with known-good reasoning patterns via prefab templates
  • 05Building custom DeepSeek Harness presets with unified injection control and phase-based tool catalogs
  • 06Testing trajectory anchoring mechanisms (zero-tool, fixed prompts, wire-level conditions) in isolation or combination

dsh-anchored-standard — FAQ

What is dsh-anchored-standard?+

It is an experimental DeepSeek Harness agent preset that anchors AI reasoning trajectories using a minimal tool catalog on the first request, then promotes to a full Standard toolset after the session becomes durable. The project was validated on DeepSeek V4 Pro but is now frozen following that model's retirement.

How do I install the anchored-standard preset?+

Clone the repository and copy the 'preset' directory into your DSH user preset root (e.g., ~/.dsh/.agent-presets/anchored-standard on Linux/macOS, %USERPROFILE%\.dsh\.agent-presets\anchored-standard on Windows). Restart DeepSeek Harness, create a blank session, and select 'Anchored Standard (experimental)' from the preset list.

Which DeepSeek Harness versions does it support?+

Developed against DeepSeek Harness 0.1.0-rc.5 and tested with compatibility patches for 0.1.3-alpha.1 and 0.1.3-alpha.2. The preset adapts to API changes (snapshotEvents fallback, prefix key migration) but was designed for the now-retired DeepSeek V4 Pro model.

Does it require API keys or paid services?+

Yes, it requires a DeepSeek API key set via DEEPSEEK_API_KEY environment variable or harness configuration. The project was originally developed for the DeepSeek V4 Pro model (now retired) and evaluated using paid API access.

What are the different mode variants included?+

The repository includes six self-contained modes: Anchored Standard (base), Zero-Anchored Standard (fixed zero-tool anchor), Whoami Standard (self-introduction warm-up), Eternal Minimal (dshx bash gateway), Wire Think-Execute Standard (tool_choice wire control), and Combo Anchored (think/gate/drip combination).

Is the project still actively maintained?+

No, the project was frozen on September 10, 2026, when DeepSeek retired V4 Pro and announced traffic routing to V4.1 Flash. New issues and pull requests are no longer accepted, but the repository remains online with all data and documentation intact.

How do I install dsh-anchored-standard?+

Open the source repository on GitHub and follow its README. dsh-anchored-standard is a agent — MCP Agents Market links you directly to the official repo.

Is dsh-anchored-standard free?+

dsh-anchored-standard is an open-source project hosted on GitHub. Check the repository for its license and any usage requirements.
