Agent-plane presentation selector: composes one agent's tools as Code Mode, native, or both

Tool-call timeout policy: a tools/execute wrapper that arms a per-tool deadline on exec.signal and returns TOOL_TIMEOUT when it wins

The shared dsh core as a profile bundle: every profile's first patch layer, inserting the base plugin rows over the empty profile root

Abstract spill storage seam (ctx.spillStore) for the DeepSeek Harness — save oversized tool text and return a retrieval locator

File-context policy plugin for the DeepSeek Harness — observed-state, read-before-edit, and version-guarded write/edit added over the ctx.fs provider seam through the fs/* event gate (no service API)

Race-fenced same-session goal-round driver

Model-facing filesystem tools (read, write, edit) over the DeepSeek Harness filesystem seam (ctx.fs)

Semantic session durability checkpoints before model requests and tool side effects

Tool registry and execution pipeline for the DeepSeek Harness

Sandbox-enforcing implementation of the DeepSeek Harness filesystem seam: fences write/edit by the per-call sandbox mode (read-only denies mutation, workspace-write contains it to the workspace + temp roots) while reads pass through

Self-referential cordis toolset: inspect the live runtime, mount and dispose model-written plugins

Abstract bash executor seam (ctx.shell) for the DeepSeek Harness

Web ask_user_question feature: host tool mount plus composer-takeover question UI

Model-facing bash tool with optional generic background-task and sandbox-escalation support

Tool-independent managed DSH_* shell environment registry

Globally named send_message, interrupt_agent, and list_agents tools over ctx.subagents continuations

Model-facing web tools (web_search, web_fetch) over the DeepSeek Harness web capability seam (ctx.web)

Sandbox-consuming implementation of the DeepSeek Harness PowerShell executor seam (confines every command via ctx.sandbox, reports denial/enforcement result facts)

Abstract web access capability seam (ctx.web) for the DeepSeek Harness — search/fetch provider registry, registration-order-independent selection, request/result vocabulary, and the WebError taxonomy

Token-meter-driven compaction policy and LLM summarization backend for the DeepSeek Harness
