dsh-anchored-standard is a DeepSeek Harness agent preset that implements a two-phase initialization strategy for language model sessions.
The tool addresses the problem of model trajectory instability by anchoring sessions on minimal conditions before promoting to fuller tool catalogs. It works by starting with a real Minimal tool schema without auto-injected context, then transitioning to a small resident catalog once the session proves durable, which unlocks access to heavier Standard tools on demand. The preset includes a base mode, two live-anchor variants, and one seeded prefab mode, along with unified injection control through a context-gate mechanism.
Developers working with DeepSeek models who need to stabilize agent behavior across tool-rich environments should consider this preset. It suits projects where session durability matters and where tool availability can be staged rather than provided all at once. The tool is explicitly a community project not affiliated with or endorsed by DeepSeek.
The project is frozen as of September 2026 following the retirement of the DeepSeek V4 Pro model that the presets were tuned for. The maintainer halted active development earlier due to cost constraints on the evaluation loops required for preset refinement, moving the repository into maintenance-only mode. The repository remains online with its history, data, and acknowledgement record intact, and the maintainer has published a closing note explaining the decision. Research material and model-agnostic components like the context-gate injection control and dose-response discovery data remain available for reference.
