+# Daily change list
+
+After **any** substantive edit or addition in this repo (skip pure Q&A with zero file changes), update the daily log **before** reporting completion to the user.
+
+## Output path
+
+```text
+docs/daily/{yyyy}-{mm}-{dd}-change-list.md
+```
+
+| Placeholder | Meaning |
+|-------------|---------|
+| `{yyyy}` | 4-digit year |
+| `{mm}` | 2-digit month (`01`–`12`) |
+| `{dd}` | 2-digit day of month (`01`–`31`) |
+
+Example: 2026-09-24 → `docs/daily/2026-09-24-change-list.md`.
+
+Create `docs/daily/` if missing. **Same calendar day**: append a new session block; do not overwrite earlier entries.
+
+## How to gather changes
+
+1. `git status` and `git diff` (staged + unstaged) for paths touched this session.
+2. Summarize **why** and **what** in plain language (modules, APIs, migrations, behavior).
+3. Note verification: `make test` / `make lint` result, or `skipped` only for docs-only with no build surface.
+
+Do not paste full diffs. List important files with one-line descriptions.
+
+## Markdown template
+
+**New file** (first entry of the day):
+
+```markdown
+# 每日变动 {yyyy}-{mm}-{dd}
+
+## {HH:MM} — {one-line title}
+
+### 概要
+
+- …
+
+### 变更范围
+
+| 类型 | 说明 |
+|------|------|
+| 功能 / 修复 / 重构 / 文档 / 配置 | … |
+
+### 主要文件
+
+- `path/to/file` — …
+
+### 验证
+
+- `make test`: pass / fail / skipped (reason)
+
+### 关联
+
+- Issue / PR / 对话上下文（如有）
+```
+
+**Append** (file already exists): add another `## {HH:MM} — …` section with the same subsections under the existing `# 每日变动` header.
+
+Use `{HH:MM}` in **UTC+8** unless the user specifies another timezone.
+
+## Quality bar
+
+- Chinese or English is fine; match the user’s language when obvious.
+- One session block per agent completion; merge duplicate bullets if the same fix is retried.
+- If the user explicitly says not to write the daily log, skip.
+
+## Order with other gates
+
+1. Finish code/docs edits.
+2. Run `make test` when required (see `verify-before-done.mdc`).
+3. Write or append this daily markdown.
+4. Tell the user the task is done (mention the daily file path).

 4. HTTP and TCP share Application services under `internal/module/{biz}/logic`. Each module is `entity` / `model` (one file per table, GORM `TableName()` → `t_*`) / `logic` (one file per function, not per table). Gin handlers only bind and call those services (MVC). REST paths are `/v1/{resource}` grouped by business; admin ops use `/api/admin/…` (see skill `http.md`). Request DTOs use go-playground/validator (`label` / `errmsg` i18n keys). Context must carry `reqctx.RealIP` and the user language (`zh-CN` / `en` / `zh-TW`). Error `msg` and notification copy come from `internal/pkg/i18n`. Table and column COMMENT is required. Message `content` is serialized bytes, not a string.
 5. MySQL: all tables `t_*`; migrations replay-all — details in `.cursor/skills/spark-im-v3/mysql.md`. After changing `migrations/*.sql`, run `go run ./cmd/migrate -config configs/config.yaml` yourself.
 6. Before finishing any code change, run `make test` at the repo root (runs `lint` first, logic coverage ≥65%). Do not report the task as OK until it passes. `make deploy` chains through `test`.
+7. After edits that touch the repo, load `.cursor/skills/daily-change-list/SKILL.md` and append `docs/daily/{yyyy}-{mm}-{dd}-change-list.md` before handoff.
 
 Do not introduce Kafka, K8s, microservices, ConversationSeq, application-layer handshake crypto, or public gnet ports.

+- 文件名格式：`{yyyy}-{mm}-{dd}-change-list.md`（示例：`2026-09-24-change-list.md`）。
+- `AGENTS.md` 与 `verify-before-done.mdc` 已挂接该流程。

+### 变更范围
+
+| 类型 | 说明 |
+|------|------|
+| 文档 / 配置 | Agent skill、daily 目录说明、Agent 与 verify 规则 |
+
+### 主要文件
+
+- `.cursor/skills/daily-change-list/SKILL.md` — skill 定义与模板
+- `docs/daily/README.md` — 目录说明
+- `AGENTS.md` — 第 7 条引用 skill
