OpenCode Session Toolkit

读取本地 OpenCode SQLite 数据库,支持跨目录检索 session、message、part、project。

以下命令默认都在当前 SKILL.md 所在目录执行。导出 Markdown 时,直接运行内置脚本:

./scripts/export_opencode_sessions.py --help

适用场景

  • 列出最近会话、按目录过滤、按标题搜索
  • 读取某个 session 的 message JSON
  • 将匹配的会话导出为一个会话一个 Markdown 文件
  • 查看 OpenCode 数据库结构和索引(按需读取 references/schema.md

工作流程

  1. 通过 opencode db path 解析数据库路径。
  2. 所有查询只读执行,避免误写。
  3. 需要字段细节时再读取 references/schema.md

1. 解析数据库路径

if ! command -v opencode >/dev/null 2>&1; then
  echo "opencode command not found in PATH" >&2
  exit 1
fi

if ! DB_PATH="$(opencode db path 2>/dev/null)"; then
  echo "Failed to resolve OpenCode DB path via: opencode db path" >&2
  exit 1
fi

if [ -z "${DB_PATH:-}" ] || [ ! -f "$DB_PATH" ]; then
  echo "OpenCode DB not found: $DB_PATH" >&2
  exit 1
fi

echo "Using DB: $DB_PATH"

列出当前存在的 DB 文件(无匹配也不会报错):

find "${XDG_DATA_HOME:-$HOME/.local/share}/opencode" -maxdepth 1 -name '*.db' -print 2>/dev/null

2. 时间转换与格式化

时间转换:所有时间字段为毫秒级 Unix timestamp,可用 datetime() 直接在 SQL 中转换。

# 在 SQL 中转换(推荐,无需外部命令)
datetime(time_updated/1000, 'unixepoch', 'localtime')

# 用 shell 辅助变量计算时间范围
NOW_MS=$(date +%s000)
LAST_7D=$((NOW_MS - 7*86400*1000))   # 最近 7 天
LAST_30D=$((NOW_MS - 30*86400*1000))  # 最近 30 天

表格对齐:普通字段查询可通过 column -t -s '|' 对齐(SQLite 默认列分隔符为 |);包含 message.data 这类长 JSON 字段时建议使用 -json 输出。

sqlite3 -readonly "$DB_PATH" "SELECT id, title, time_updated FROM session LIMIT 5;" | column -t -s '|'

3. 常用只读查询

💡 不含长 JSON 字段的查询可追加 | column -t -s '|' 以对齐输出表格。

列出最近 20 个 session(按更新时间倒序)

sqlite3 -readonly "$DB_PATH" \
  "SELECT id, title, directory,
          datetime(time_updated/1000,'unixepoch','localtime') as updated
   FROM session
   ORDER BY time_updated DESC
   LIMIT 20;" | column -t -s '|'

按目录过滤 session

sqlite3 -readonly "$DB_PATH" \
  "SELECT id, title, datetime(time_updated/1000,'unixepoch','localtime') as updated
   FROM session
   WHERE directory LIKE '/path/to/project%'
   ORDER BY time_updated DESC
   LIMIT 20;" | column -t -s '|'

按 project_id 过滤 session(最精确的目录关联方式)

sqlite3 -readonly "$DB_PATH" \
  "SELECT s.id, s.title, s.directory,
          datetime(s.time_updated/1000,'unixepoch','localtime') as updated
   FROM session s
   WHERE s.project_id = 'your-project-id'
   ORDER BY s.time_updated DESC
   LIMIT 20;" | column -t -s '|'

project_id 对应 project 表的 id 字段,可通过 SELECT id, worktree, name FROM project; 查看项目列表。

跨所有目录全量列出 session(带 project 信息)

sqlite3 -readonly "$DB_PATH" \
  "SELECT s.id, s.title, s.directory, p.worktree,
          datetime(s.time_updated/1000,'unixepoch','localtime') as updated
   FROM session s
   LEFT JOIN project p ON s.project_id = p.id
   ORDER BY s.time_updated DESC
   LIMIT 50;" | column -t -s '|'

按时间范围过滤

# 最近 7 天活跃的 session
sqlite3 -readonly "$DB_PATH" \
  "SELECT id, title, datetime(time_updated/1000,'unixepoch','localtime') as updated
   FROM session
   WHERE time_updated > $(( $(date +%s000) - 7*86400*1000 ))
   ORDER BY time_updated DESC
   LIMIT 20;" | column -t -s '|'

# 今天创建的 session
sqlite3 -readonly "$DB_PATH" \
  "SELECT id, title, datetime(time_created/1000,'unixepoch','localtime') as created
   FROM session
   WHERE date(time_created/1000,'unixepoch','localtime') = date('now','localtime')
   ORDER BY time_created DESC
   LIMIT 20;" | column -t -s '|'

查看某 session 的消息内容

sqlite3 -readonly -json "$DB_PATH" \
  "SELECT m.id, datetime(m.time_created/1000,'unixepoch','localtime') as created, m.data
   FROM message m
   WHERE m.session_id = 'your-session-id'
   ORDER BY m.time_created ASC;"

解析 message.data JSON 字段

# 提取 role、modelID 等关键字段(json_extract)
sqlite3 -readonly "$DB_PATH" \
  "SELECT id,
          json_extract(data, '$.role') as role,
          json_extract(data, '$.modelID') as model,
          datetime(time_created/1000,'unixepoch','localtime') as created
   FROM message
   WHERE session_id = 'your-session-id'
   ORDER BY time_created ASC;" | column -t -s '|'

# 搜索 message 内容(full-text like)
sqlite3 -readonly "$DB_PATH" \
  "SELECT id, json_extract(data, '$.role') as role, time_created
   FROM message
   WHERE data LIKE '%keyword%'
   ORDER BY time_created DESC
   LIMIT 20;" | column -t -s '|'

搜索 session 标题

sqlite3 -readonly "$DB_PATH" \
  "SELECT id, title, directory, datetime(time_updated/1000,'unixepoch','localtime') as updated
   FROM session
   WHERE title LIKE '%keyword%'
   ORDER BY time_updated DESC
   LIMIT 20;" | column -t -s '|'

查看会话统计

sqlite3 -readonly "$DB_PATH" \
  "SELECT title, summary_additions, summary_deletions, summary_files,
          datetime(time_created/1000,'unixepoch','localtime') as created
   FROM session
   ORDER BY time_updated DESC
   LIMIT 20;" | column -t -s '|'

4. 导出会话为 Markdown

导出脚本会将每个会话写成一个独立的 Markdown 文件。默认行为:

  • 文件名 = 会话标题 + 创建时间
  • 时间过滤默认使用 time_updated,除非显式传入 --time-field created
  • 默认跳过 step-start / step-finish,减少噪声
  • project.name 为空时,导出分组目录会回退到 worktree 的目录名,再不行就用 global

按某个 project 导出

./scripts/export_opencode_sessions.py \
  --project opencode-session-toolkit \
  --output-dir ./exports/opencode-session-toolkit

--project 会对 project_idproject.nameproject.worktreesession.directory 做子串匹配。

按时间段导出

./scripts/export_opencode_sessions.py \
  --start 2026-03-01 \
  --end 2026-03-24T23:59:59 \
  --time-field updated \
  --output-dir ./exports/march

支持的时间格式:

  • ISO 日期:2026-03-24
  • ISO 日期时间:2026-03-24T22:35:37
  • Unix 秒级 / 毫秒级时间戳

全量导出并按 project 分组

./scripts/export_opencode_sessions.py \
  --all \
  --group-by-project \
  --output-dir ./exports/all

输出结构示例:

exports/all/
  OrchAI/
    Migration work planning with subagent discussion_2026-03-23_23-48-07.md
  global/
    opencode-session-toolkit 命令验证与优化_2026-03-24_22-35-37.md

其他常用过滤条件

  • --session-id ses_xxx:按精确 session id 导出
  • --title-contains keyword:按会话标题匹配
  • --directory-contains keyword:按工作目录匹配
  • --archived include|exclude|only:过滤归档状态
  • --filename-time-field created|updated:控制文件名里拼接哪一个会话时间
  • --include-part-type text --include-part-type tool:只导出指定 part 类型
  • --exclude-part-type reasoning:排除噪声 part 类型
  • --overwrite:目标文件已存在时直接覆盖,而不是自动追加 session id 避免重名

如果不传任何过滤条件,脚本会要求显式加 --all,避免误触发全量导出。

5. 查看 schema

sqlite3 -readonly "$DB_PATH" ".schema session"
sqlite3 -readonly "$DB_PATH" ".schema message"
sqlite3 -readonly "$DB_PATH" ".schema part"
sqlite3 -readonly "$DB_PATH" ".schema project"

完整字段与索引说明见 references/schema.md

6. 查看所有表

sqlite3 -readonly "$DB_PATH" ".tables"

7. 示例输出

id          title                     directory                   updated
----------  -----------------------  --------------------------  -------------------
ses_abc123  My Session - 2026-03-24  /home/user/project         2026-03-24 10:00:00
ses_def456  Another Session          /home/user/other           2026-03-23 15:30:00

(配合 | column -t -s '|' 对齐后的效果)

8. 注意事项

  • 数据库使用 WAL 模式,会产生 .db-wal.db-shm 文件
  • 所有时间字段为毫秒级 Unix timestamp,用 datetime(ts/1000,'unixepoch','localtime') 在 SQL 中直接转换
  • data 字段为 JSON:做结构化抽取时用 json_extract(data, '$.field'),查看原始消息时优先 sqlite3 -json
  • Session 隔离按 project_id,跨目录检索时建议关联 project.worktree
  • 直接修改数据库可能导致数据损坏,操作前建议备份
  • account / control_account 表含敏感凭证,查询时注意脱敏
