dsh-brief-session-title

English | 中文

A DeepSeek Harness (DSH) session-title plugin that condenses a full sentence into a single word for easier recall.

Why this plugin

DSH generates session titles with the official session-title-first-prompt-llm plugin, which often outputs a complete sentence — a verbatim echo like "Explain what JavaScript closures are" ends up in the sidebar, long and hard to scan.

The root cause is the official prompt: its only length constraint is "Aim for about 5 words" — "aim for" is a soft target that models routinely overshoot, and it asks for "concise" without showing what concise means. The goal is not specific enough, and that is what makes titles wordy.

This plugin keeps all official logic untouched and changes exactly one thing: the system prompt — explicit rules plus correct/incorrect examples that turn "concise" into an executable standard.

Examples

Core idea: prompt optimization

The new prompt gives the model four hard rules:

1. PLAIN ENGLISH for English output — plain and direct;
2. literary-vernacular hybrid for Chinese output — a compact classical-modern blend (e.g. "浅说", "文法表达");
3. Avoid verbs in the output — verbs are the skeleton of a sentence; remove them and the sentence collapses into a phrase;
4. Shrink to under 5 words, like a professional poet — shorter is better.

Six correct/incorrect example pairs anchor the target style, so the model imitates the pattern instead of guessing what "concise" means.

Features

• Zero intrusion: identical to the official first-prompt-llm logic (first human message, streaming generation, fallback on failure) — only the prompt changes;
• Auto take-over: mutually exclusive with the official plugin; on load it shuts the official provider down and registers itself, so exactly one title generator stays active;
• Fail-safe: on model error, timeout, or empty output, it falls back to the official deterministic fallback title;
• Configurable: input byte cap, output token cap, and timeout are all tunable.

Installation

This plugin is a dsh bundle — install it directly from GitHub, no manual config editing:

dsh plugin --profile web add github:Relethe/dsh-brief-session-title

If the package is published to npm, the same command works with the package name:

dsh plugin --profile web add dsh-brief-session-title

For a local checkout (relative paths resolve against your invoking directory):

dsh plugin --profile web add ./dsh-brief-session-title

dsh plugin forwards its arguments to pnpm and then reconciles: because this package declares dsh.bundle, it joins the profile's bundle layer automatically, and the bundle's own cordis.patch.yml applies (disable the official title plugin + mount this one).

Restart DSH — new session titles take effect from then on.

Configuration

Notes

• New titles only: existing sessions keep their stored titles;
• Manual renames pin: a user-renamed title is never overwritten by automatic generation (official DSH behavior);
• To revert: dsh plugin --profile web remove dsh-brief-session-title — the official title plugin resumes automatically.
