dsh-pr-watch

Reports what changed in your authored pull requests since your last check — merged, closed, or gone stale.

dsh-pr-watch is a dependency-free DeepSeek Harness (dsh) plugin that exposes one agent tool, pr_watch. It tracks every pull request you authored, across all repositories — including ones you have never cloned — and tells you only what changed since you last looked.

Status: pre-release. The implementation is complete: the plugin registers exactly one tool, pr_watch, and the whole pipeline is covered by the test suite. Nothing is published to npm yet, so the install command below does not work today. It is included so the intended path is clear, not because it is ready.

What works today

Piece	State
package.json, tsconfig.json, tsdown.config.ts, bundle	✅ In place
src/types.ts — PrRecord, Snapshot, Delta, constants	✅ In place
src/delta.ts — the pure diff core	✅ In place
src/snapshot.ts — load, quarantine, atomic save	✅ In place
src/gh-exec.ts — gh invocation and record mapping	✅ In place
src/tools/watch.ts — the report renderer	✅ In place
src/tools/pr-watch.ts — the pr_watch tool	✅ In place
src/index.ts — plugin entry (name, inject, apply)	✅ In place, registers one tool: pr_watch
CI — typecheck, lint, format, test, build	✅ Green on every pull request
Published to npm	⛔ Not yet — the install command does not work

Installing this plugin today registers pr_watch. What is still missing is the release itself, not the tool.

Test counts are deliberately not listed here. They went stale within one pull request, and CI already reports them per commit — a number in prose is a claim nobody re-checks.

Why

An agent has no memory of your last check, so every status question gets re-derived from scratch. That is fine for one pull request and useless for thirty. The friction is not seeing your pull requests — it is re-checking the same ones over and over and having to remember what the state was last time.

pr_watch closes that gap by storing a snapshot and reporting deltas.

Features

Implemented, pending release. Everything below is built and covered by the test suite. It is not on npm yet, so there is no way to install it other than from a checkout — see Installation and What works today.

Behaviour	Detail
Merged	A pull request you authored was merged
Closed without merge	Distinguished from a merge, not lumped in with it
Became stale	No activity for 14 days (configurable)
Newly noticed	A pull request is open that the snapshot did not know about — including one that was closed and then reopened
Uncloned repositories	Tracked by owner/repo#number, so a local checkout is never required
Reported once, then silent	Merges and staleness never repeat on later checks

How it works

The naive approach — fetch open pull requests, diff against the snapshot — cannot work. The moment a pull request merges it leaves the open list, so a bare diff cannot tell "merged" from "closed unmerged", and an empty result looks identical to a failed gh call.

So pr_watch fetches in two phases:

1. Enumerate every open pull request you authored, in one call.
2. Resolve each snapshot entry that left that set, individually, to learn its terminal state.

Only pull requests that actually changed incur a second call — normally zero or one per check.

Installation

dsh plugin --profile PROFILE add dsh-pr-watch

Replace PROFILE with the dsh profile you actually run — the tool only appears in that one. The Desktop app manages a profile of its own, so from its terminal omit the flag entirely and let it target the active profile:

dsh plugin add dsh-pr-watch

Not yet published, so neither command works today. They are the intended path once the package is released.

Until then, install from a checkout. dsh plugin forwards its arguments to pnpm in the profile directory and anchors a relative path spec to the directory you ran it from, so a local link works on every platform:

pnpm install && pnpm run build
dsh plugin --profile PROFILE add link:.

Run that from the repository root, and use the same profile you would have used above.

Requires the GitHub CLI (gh) on your PATH, authenticated:

gh auth login

dsh-pr-watch stores no credentials of its own. It relies entirely on gh's own keyring-backed authentication.

Usage

Ask the agent to check your pull requests, or call the tool directly.

{
  "staleDays": 14,
  "all": false
}

Typical output:

✅ Merged (2):
  octo/repo#41 — Add Russian locale (last activity 1 day ago)
  octo/repo#38 — Fix broken link (last activity 3 days ago)

⏳ Became stale (1):
  octo/repo#29 — docs: clarify install steps (last activity 21 days ago)

🆕 Newly noticed (1):
  octo/repo#44 — Add MCP server entry (last activity today)

Run it a second time and only genuine changes appear. A merge reported today is never reported again.

Parameters

Parameter	Type	Description
staleDays	integer	Whole days without activity before a pull request counts as stale. Defaults to 14. Must be between 1 and 3650; 0 is refused as a likely mistake.
all	boolean	List every open pull request instead of only what changed. Useful on first run, where everything is "newly noticed". Defaults to false.

Configuration

v1 exposes everything through the tool's two parameters above. It reads no settings file, so there is nothing else to configure yet.

Setting	Default	Settable in v1	Purpose
staleDays	14	Yes — tool parameter	Days without activity before a pull request is reported stale
pruneDays	90	No — compile-time constant	Drop entries that reached a terminal state this long ago
Snapshot path	$DSH_HOME/pr-watch/snapshot.json	No — derived from the environment	Falls back to ~/.dsh/pr-watch/snapshot.json when DSH_HOME is unset

Two further keys appear in the design doc — ignoreRepos and a user-settable snapshotPath — but they are deferred to v2 and not implemented. Honouring them needs a settings loader that does not exist yet, and ignoreRepos additionally needs a rule to evict ignored entries from the snapshot: an entry dropped from enumeration but kept in the snapshot would never resolve, so every check would report it as unresolved forever. See the plan's refinements section for the full reasoning.

Behaviour notes

• Staleness fires on transition, and only once. A pull request that has been stale for weeks is reported the first time it crosses the threshold, then stays quiet. If it sees new activity, the staleness clock resets and it can be reported again later.
• A failed enumeration writes nothing. If the one gh search call fails, or its output cannot be read, the snapshot is left untouched so pending changes are not silently marked as seen. A failure in the resolve phase is narrower: every outcome that was determined is still recorded, and the entry that could not be resolved stays OPEN and is retried on the next check — without being announced again in the meantime.
• A reopened pull request is announced again. Closing is not final: if a closed pull request is open again at the next check, it is reported as newly noticed and resumes normal tracking. A merge is treated as final, since it cannot be undone.
• The snapshot is written atomically (temporary file, then rename), so an interrupted write can never leave a truncated file that reads as "everything vanished".
• A corrupt snapshot is quarantined, never discarded. It is moved to snapshot.json.corrupt-<n> and the tool says so in its output, including when the check fails afterwards — the move is irreversible, so that message is the only chance to report it.

Known limitations

A pull request opened and merged between two checks is invisible. It is absent from the open set (it already merged) and absent from the snapshot (it did not exist when the snapshot was taken), so neither phase sees it. This is a direct consequence of enumerating by current state rather than by activity window, and it only becomes likely if you check infrequently. The fix — an activity-window query — is recorded in the design doc as a v2 candidate.

New comments and reviews are not reported. An outcome like "merged" is not the same as "a maintainer replied asking for changes", and the latter is often what should change your next action. It is deferred rather than overlooked: it needs a separate data source and a per-entry comment cursor.

CI status is not reported.

One snapshot per GitHub identity. Running under a second account would share a snapshot and produce spurious "newly noticed" entries.

Roadmap

The design is complete and the work is broken into fifteen tasks in the implementation plan.

State	Tasks
✅	1–3 — scaffolding, types, test fixtures
✅	4–7 — the pure delta.ts core
✅	8–10 — snapshot.ts: path resolution, load, quarantine, atomic save
✅	11–12 — gh-exec.ts: invocation, record mapping, error handling
✅	13–14 — renderWatch() and the pr_watch tool, then registration
✅	15 — build wiring, README, artifact checks

The remaining work is a release, not a feature: the package has not been published, so dsh plugin --profile web add dsh-pr-watch cannot resolve yet.

Development

pnpm install
pnpm run build        # tsdown → lib/
pnpm test             # vitest — no network access
pnpm run lint         # oxlint
pnpm run typecheck    # tsc --noEmit
pnpm run format       # prettier --write .

The test suite makes no network requests and never runs gh. delta.ts and tools/watch.ts are pure — no filesystem, no network, no clock — and every IO module takes its dependencies as arguments, so the whole pipeline is driven by fixtures and injected executors rather than mocks.

To check the built artifact rather than the sources, run pnpm run build and then load lib/index.js: it must export name, inject, apply, and a tools array of exactly one entry. pnpm pack should produce a tarball containing only lib/index.js, cordis.patch.yml, package.json, README.md, LICENSE, and SECURITY.md.

On Windows, pnpm organises node_modules with symlinks, which needs Developer Mode or an elevated shell; without it, installs fail with EPERM. The npm cache and store are redirected inside the repository by .npmrc, so nothing is written outside the checkout.
