dsh-pr-chip

Pull request state on every DSH session row — a small icon that tells you whether the work behind a chat is still open, sitting as a draft, already merged, or closed.

A DeepSeek Harness (DSH) plugin: host half resolves the state, browser half draws the chip in the sidebar's session row. Glyph shapes follow the badge the Codex desktop app uses; colours are GitHub's.

How it works

The session record never stores PR state. It stores an identity, and the state is always queried:

sessionId ──resolve cwd──> (ownerRepo, branch) ──gh pr list --head──> state

cwd is resolved in two steps: the workspace owning the session in storages/workspace.json, and — when that misses — the session's own on-disk directory name (--Users-me-proj--, with ~XXXX escapes and hyphens split by walking cut points that exist on disk). The second path is real: a session's cwd is not always its workspace path, and old sessions outlive their workspace row.

State is cached in memory only (30s for an answer, 60s for "no PR"), keyed by cwd, so sessions sharing a workspace share one lookup. Lookups are de-duplicated in flight and capped at four concurrent child processes.

Where the identity comes from, in order

1. Live worktree — session cwd → git branch → gh pr list --head
2. Remembered identity (links.json) — the checkout was archived or deleted
3. Live events — a gh pr create seen on the session event bus, paired with the output of that same call id
4. One-shot backfill — for sessions predating the install, the transcript is scanned once; the result is recorded and never rescanned

Both 3 and 4 accept only gh pr create's own output shape — one bare PR URL — so a command that merely prints a URL, or prose that quotes one, cannot match.

Install

# from a local checkout
dsh plugin --profile <profile> add link:/path/to/dsh-pr-chip

# from git
dsh plugin --profile <profile> add github:OWNER/dsh-pr-chip

Restart the host afterwards: the bundle list is composed at startup.

On the DSH desktop app the profile is managed by the application and dsh plugin refuses it; add the dependency and the dsh.profile.bundles entry by hand, plus the node_modules symlink.

Requirements

• DSH ≥ 0.2.1 (the sidebar.session.row.leading seat passes { sessionId })
• git and gh on PATH, with gh auth status healthy

When nothing is drawn

• the directory is not a git worktree (a temporary path is fine — only a worktree matters)
• the branch is a detached HEAD
• the branch has no PR and no remembered identity
• gh is missing or unauthenticated

The endpoint answers state: null with a reason (no-branch, no-pull-request, workspace-missing, gh-failed) and the row renders exactly as before.

Files it writes

Everything lives under $DSH_HOME/pr-chip/:

file	contents
links.json	session → (ownerRepo, branch, number) identity, atomically written, 500 entries max
scanned.json	sessions whose transcript was already backfilled once
host-loaded.jsonl	one line per host start (diagnostics)

Offline

The chip keeps the last state it observed. When gh cannot reach GitHub the endpoint answers with the stored state marked stale: true instead of null, so a dropped connection hides nothing — and a failed lookup never overwrites the good state that is already on disk. The first successful query after reconnect replaces it.

A session that never resolved a PR has nothing stored, so nothing is invented: it stays without a chip.

Where it shows

sidebar.session.row.leading — the 16px cell before the session title. DSH renders that cell only while the row is idle, and never for archived or blank rows.

DSH has no "always visible after the title" seat: sidebar.session.row.hover lives inside the hover card, and sidebar.workspaces.session.row.action appears only while hovering. The leading cell is the only permanent slot, so the chip lives there.

中文

会话行上的 PR 状态图标：open / draft / merged / closed 四态，颜色沿用 GitHub 配色（#1f883d / #6e7781 / #8250df / #cf222e）。

• 状态从不落盘，只记身份；每次查询，带缓存。
• 三条兜底：落盘的身份、会话事件里的 gh pr create、一次性日志回溯。
• 只认真实输出：必须是 gh pr create 自己返回的裸 URL，正文里提到的 URL 不算。

安装后重启宿主生效。没有 PR 的会话行外观完全不变。
