插件

DSH plugin: persistent SQLite tools for the agent (sqlite_query / sqlite_exec / sqlite_tables / sqlite_export / sqlite_import), a read-only table browser settings page, and a persistence-usage prompt rule — zero runtime deps beyond Node 22 node:sqlite.

MaxCompute (ODPS) data analysis plugin for DeepSeek Harness: metadata browsing, cost-gated SQL execution, background jobs and result export.

Cross-session knowledge for DeepSeek Harness: ctx.knowledge service + knowledge_* tools, SQLite FTS5 trigram retrieval (CJK substring) with L1 query expansion. V1.11 contract (write/update/search/list/delete + budget + events + error codes).

Cloudflare D1 数据库工具：d1_list/query/exec/schema/stats/health，通过 D1 HTTP API 访问，默认只读（SQLite 语义的词法级只读保护）、LIMIT 行数上限、CSV/JSON 查询输出与写审批门。

经 MCP stdio 把 Agent 接入持久化 OKF 记忆库：Python 服务端（SQLite FTS5 + Markdown），10 个工具用于检索与写入决策、事实和偏好。

Turns attached files into versioned evidence: `search_documents` builds a private local index (SQLite FTS5 after a startup capability probe, dependency-free JS fallback otherwise) and returns compact evidence blocks carrying an exact coordinate — PDF page, PPTX slide, text/DOCX line range, or quoted XLSX `Sheet!Range` — which `read_document` expands only while the content version still matches. Contiguous CJK runs are indexed as overlapping bigrams and queried as phrases, so word order is preserved; uploaded raster images take the native vision attachment path instead.

Long-term memory for DeepSeek Harness backed by Hypatia: a host-side CLI adapter, a plugin-owned SQLite control ledger, same-request recall, and narrow memory tools. Requires the `hypatia` CLI on PATH.

DSH 工程师级数据库插件（修复版 fork）：sql_list/query/exec/schema/stats/health 六工具，SQLite/MySQL/PostgreSQL 三引擎、多连接、只读模式与写操作审批门、词法级只读保护、流式行数钳制 + LIMIT 下推、查询/写超时硬兜底与连接超时。

智能体中途常用的小工具集：JSON/YAML 互转、JSON Schema 校验、文本 diff、JWT 解码、正则测试、SQL 方言转译等

基于人工维护的表、字段和指标语义元数据，结合 Qdrant 与 Elasticsearch 召回，通过析问服务生成、校验并执行 MySQL 分析查询。

格式化与校验 JSON / YAML / TOML / SQL，并给出出错的行列位置。

多租户账户与授权：PostgreSQL 存储、admin 管理 API、每账户独立工作目录

PostgreSQL 持久个人记忆：MCP 记忆工具 + 可查看记忆与候选的 Web 面板。
