dsh-github-picker

GitHub issue and pull request references for the DeepSeek Harness web GUI. Click the GitHub icon at the bottom-right of the input box (the composer's tool row, next to the send button) to open a searchable list of the current workspace repository's issues and pull requests, and insert a reference — a GitHub URL, or an @owner/repo#number mention.

Install or Update

dsh plugin --profile web add dsh-github-picker

Use the same command to update an existing installation — it installs the latest published version, so no version tracking is needed. Restart dsh web after installation so the Host and browser client load the new version.

To pin a specific release, append the version, e.g. dsh plugin --profile web add dsh-github-picker@0.3.0.

The npm package ships the committed lib/ bundles (see files in package.json); no build happens on install.

Usage

Click the GitHub icon at the bottom-right of the input box. A searchable popup opens with the repository's recent issues and pull requests; keep typing in its search field to filter by number or title (a number prefix ranks first, like GitHub's own autocomplete). Click a row (or press Enter with the field focused and a row picked via click) to insert the reference; Escape or a click anywhere outside closes the popup. A search failure (gh CLI missing, not authenticated, rate limited, network error, unresolved repository) renders as one localized hint row instead of a silent close.

Each row shows GitHub's own state icon, the title, and the #number tag:

State	Icon	Color
Open issue	issue-opened	green
Closed issue	issue-closed (check)	purple
Open PR	git-pull-request	green
Draft PR	git-pull-request-draft	gray
Closed, unmerged PR	git-pull-request-closed (×)	red
Merged PR	git-merge	purple

Picking inserts one of two texts, chosen in Settings (Insert format):

@owner/name#125                                 # format: ref (default)
https://github.com/owner/name/issues/125        # format: url

Before the agent starts a step, the Host scans the draft for GitHub references — URLs, @owner/repo#number forms, and bare #number tokens — and adds a short reference message for each:

<github-reference repo="owner/name" number="125" />

The plugin passes the repository and number only — it never fetches issue bodies. The agent can inspect a reference with its available tools when the task requires it.

Data Source

The plugin uses the gh CLI exclusively — reuse the local gh login and call gh api search/issues, which returns issues and pull requests in one query. No device flow, OAuth app, or stored credential is involved; the settings page shows the gh connection status (which accounts gh auth status reports). gh CLI works on macOS, Linux, and Windows.

The repository is always resolved from the workspace git remote get-url origin (https, ssh, and git@ forms); without a resolvable repository the popup shows a hint row explaining how to add a remote.

Settings

Open Settings -> GitHub 引用 to configure:

• Connection card — the gh CLI connection status: a GitHub-marked card showing "GitHub via gh CLI" with a Connected (green) or Not connected pill.
• Insert format — @owner/repo#number (default) or GitHub URL for the picked text.

The list loads 12 entries per page and fetches the next page as you scroll to the bottom, through the end of the result set — there is no result cap.

There is no enable switch: the picker is always available in the composer.

Configuration

Host plugin configuration goes into the selected profile's cordis.patch.yml:

- id: dsh-github-picker
  config:
    searchTimeoutMs: 15000
    repoCacheTtl: 30000

• searchTimeoutMs bounds provider calls (default 15000).
• repoCacheTtl caches the resolved repository per workspace (default 30000 ms).

The per-search result cap is a durable setting managed from Settings -> GitHub 引用 (no Host restart needed to change it).

A Host config change needs a dsh web restart; a pure client change only needs a browser refresh.

Notes

• The picker is a component in the framework's conversation.input.right composer slot (the seat just before the send button), the same seam the reference dsh-skill-picker uses: an icon button whose popup is a plain sibling positioned absolute; bottom: calc(100% + 8px); right: 0 inside a relative wrapper. No custom trigger, overlay, or keyboard capture exists.
• Picking writes the full next draft through the framework input machine (inputActions.setDraft), so undo history and the Host's mention scanning work automatically.
• The popup loads the recent issue/PR list page by page (12 per page) and fetches the next page as you scroll to the bottom, through the end of the result set — there is no result cap (cached per session for 30 seconds; reopening is instant within the TTL and refetches after it), then filters locally per keystroke, so typing never stacks provider calls.
• The #number / URL / @owner/repo#number mention grammar is shared by the Host's pre-step scanner (scanMentions) and the picker's inserted text; keep them in sync when changing either.
• A search failure is classified and rendered in the popup as one localized hint row (see the picker.error.* copy in src/client/locales.ts), so "gh is not installed" is visible instead of a silent close.

Development

pnpm install
pnpm run check

The check ladder is typecheck + tests + build with 100% coverage per source file. Dev dependencies are link: entries into the installed harness packages (see AGENTS.md); built files under lib/ are committed so profile installation runs without a build.

To install a local checkout instead (development builds or unreleased changes), add the package to ~/.dsh/profiles/web/package.json:

{
  "dependencies": {
    "dsh-github-picker": "file:/path/to/dsh-github-picker"
  },
  "dsh": {
    "profile": {
      "bundles": ["...", "dsh-github-picker"]
    }
  }
}

Then pnpm install inside the profile and restart dsh web. Refresh the browser page. The plugin serves at /plugins/dsh-github-picker/client.js and the gateway routes /api/githubPicker/*. The client bundle is read per request, so a pure client change only needs a refresh; a Host contract change needs the dsh web restart.
