dsh-session-title-dated

English | 中文

A DeepSeek Harness title provider that names every new session in the form:

DATE | CATEGORY | NAME

For example:

1028 | 分析 | 绿洲短剧平台验证
1027 | 整改 | 四台设备第十题验收返修
1026 | 部署 | Ubuntu 环境初始化

Dates are computed by the plugin from the session's creation time, never by the model. Categories are chosen from a small configurable taxonomy and validated locally. The model only proposes the category and the name; the provider owns the final format. If the model is unavailable, times out, or returns invalid output, a deterministic local fallback still produces a correctly shaped title.

Why

Long-lived workspaces collect dozens of sessions whose titles are either the first few words of the first message or an auto-summary that drifts. A fixed date | category | name convention makes the sidebar scannable across projects, and mirrors conventions used by other coding agents.

Requirements

• DeepSeek Harness >=0.2.1-rc.3 <0.3.0.
• A working model route for the session; the title request uses the session's current provider/model unless configured otherwise.

Install

DSH Desktop / Web with Discover

Add this market index source in Plugins → Discover → Index sources:

https://cdn.jsdelivr.net/gh/xuedipiaofei/dsh-session-title-dated@v0.1.0/market/index.json

Then install Dated session titles from the list. The plugin installs as a profile bundle and appears in the Plugins page, where it can be enabled or disabled like any other bundle. The index pins a GitHub commit for reproducible installs; the package is also published on npm.

CLI

From GitHub:

dsh plugin --profile <profile> add github:xuedipiaofei/dsh-session-title-dated

The package is also on npm, so the shorter form works:

dsh plugin --profile <profile> add dsh-session-title-dated

For a local checkout:

dsh plugin --profile <profile> add ./dsh-session-title-dated

The Electron Desktop profile is managed by the application; use its Plugins page rather than dsh plugin --profile desktop.

The bundle patch disables the shipped session-title-llm row and inserts this provider. Do not enable the official @deepseek-ai/dsh-experimental-session-titles-bundle at the same time: both replace the same provider slot, and the title service accepts only one provider.

How it works

• cordis.patch.yml disables session-title-llm and inserts the session-title-dated row from this package.
• lib/index.js registers a provider through ctx.sessionTitle.register() and reuses @deepseek-ai/dsh-session-title-llm for route selection, timeouts, cancellation, token limits, and exact auxiliary-request logging.
• lib/format.js is dependency-free: date formatting, category validation, name sanitizing, composition, and UTF-8 byte truncation.

The provider computes the date from session.header.createdAt in the configured time zone, asks the model for {"category":"...","name":"..."}, validates the category against the configured taxonomy, clips the name to the title service's byte budget, and writes one session/title event.

Configuration

Override the row in the profile's cordis.patch.yml:

- id: session-title-dated
  config:
    cadence: first-prompt
    dateFormat: YYMM
    timeZone: Asia/Shanghai
    categories:
      - Analysis
      - Build
      - Fix
      - Debug
      - QA
      - Deploy
      - Docs
      - Other
    maxNameChars: 20

Field	Default	Meaning
cadence	first-prompt	Name once after the first eligible message, or all-prompts to retitle as the task evolves
dateFormat	MMDD	MMDD (1028), YYMM (2610), or YYYYMMDD (20261028)
timeZone	Asia/Shanghai	Time zone used to derive the date
categories	Chinese 8-item set	Categories the model may choose; labels are also used by the local fallback classifier
maxNameChars	20	Character cap for the name before the byte cap applies
maxTitleBytes	service cap (80)	Effective cap is the smaller of this and session-title's maxTitleBytes
maxInputBytes	8192	Input budget for the title request
maxOutputTokens	4096	Output cap, including reasoning tokens
timeoutMs	60000	End-to-end title-request deadline
provider / model	session route	Optional pair to route title generation independently

The default taxonomy is Chinese. Supply categories to use any other language or domain; the prompt lists the configured labels and the local fallback maps common English and Chinese keywords onto them.

1028 | 分析 | occupies 16 UTF-8 bytes, leaving about 21 Chinese characters within the default 80-byte title budget. Longer names are truncated at a code-point boundary.

Privacy and cost

• By default (first-prompt) the first eligible user message is sent to the model. With all-prompts, the first message plus up to five recent messages are sent. Message text is framed as JSON to keep user content from breaking delimiters.
• The request uses the session's configured provider/model, or the optional provider/model override. The plugin makes no other network calls and collects no telemetry.
• One auxiliary request is made per session by default. all-prompts makes one per new user message. Title work is asynchronous and never delays the main agent response; maxOutputTokens, maxInputBytes, and timeoutMs bound it.
• The resulting title is stored in the session log as a normal session/title event. A manual rename pins the title and later automatic revisions do not overwrite it.

Compatibility notes

• This package targets the DSH 0.2 line. engines.dsh refuses to install it on 0.3+ until it is updated against the new title API.
• The bundle assumes the shipped row id session-title-llm. If another title provider is already registered, activation fails rather than silently winning; disable the other provider first.
• The provider imports @deepseek-ai/dsh-session-title-llm dynamically. A missing or incompatible executor degrades to local naming, but a changed ctx.sessionTitle API can prevent registration. Pin the DSH range when publishing a release.

Development

The repository has no runtime or build dependencies.

npm test              # format tests, provider tests with a stubbed executor, metadata/index checks
npm run validate:index # optional: validate market/index.json with the official validator if installed
npm run pack:check    # inspect the npm tarball contents

The provider test redirects @deepseek-ai/dsh-session-title-llm to test/support/stub-executor.mjs with Node's module.registerHooks, so it exercises the real provider without a DSH install or model credentials.

Release steps are in PUBLISHING.md.
