PR Monitor

Your coding agent opens a pull request and moves on. PR Monitor keeps watching the PR for it: new commits, CI results, reviews, comments, merge conflicts, and the final merge or close. When something happens, a short [PR Monitor] message lands in the agent conversation that started the monitor so the agent can act on it.

Works with OpenCode, Claude Code, Codex, Pi, Oh My Pi (OMP), DeepSeek Harness, and Hermes.

Install

Every host uses the GitHub CLI to talk to GitHub. Install it first, then make sure you are logged in as the account that should read and label your pull requests:

gh auth status

Then add the plugin to your host.

OpenCode

Needs OpenCode 1.17 or newer. Add the plugin to your project opencode.json, or to ~/.config/opencode/opencode.json for every project:

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["@sesori/pr-monitor-opencode"]
}

Restart OpenCode. It installs the package on startup. Pin @sesori/pr-monitor-opencode@X.Y.Z if you prefer to upgrade on your own schedule.

Claude Code

Needs Node.js 18 or newer on macOS or Linux. Inside Claude Code:

/plugin marketplace add sesori-ai/pr-monitor-plugin
/plugin install pr-monitor@sesori

You get the pr_monitor tool plus four slash commands: /pr-monitor:watch, /pr-monitor:status, /pr-monitor:ready, and /pr-monitor:unready.

Codex

Needs Codex 0.153 or newer and Node.js 18 or newer on macOS or Linux.

codex plugin marketplace add sesori-ai/pr-monitor-plugin
codex plugin add pr-monitor@sesori

Codex delivers reports through hooks, and it will not run a plugin's hooks until you trust them. One more step:

Open codex in a terminal as the same user and CODEX_HOME that your Codex CLI or app-server uses.
Run /hooks and trust all four pr-monitor@sesori entries: SessionStart, UserPromptSubmit, PostToolUse, and Stop.
Go back to your conversation and send one new prompt. Monitoring can start after that.

If you use Codex through another client, such as Sesori, run /hooks on the machine that hosts the Codex app-server. See Codex in the host guide if monitoring says the hook is not registered.

Pi

Needs Pi 0.84.2 or newer and Node.js 22.19 or newer.

pi install npm:@sesori/pr-monitor-pi

Oh My Pi (OMP)

Needs OMP 18.0.3 or newer.

omp plugin install @sesori/pr-monitor-pi

DeepSeek Harness

DeepSeek Harness support is a developer preview. It needs Harness 0.1.5-rc.2 or newer, Node.js 22.19 or newer, and pnpm 10 or newer. Install the bundle into the long-lived Web profile, inspect the composed config, then start it:

npx @deepseek-ai/dsh@0.1.5-rc.2 plugin --profile web add @sesori/pr-monitor-deepseek
npx @deepseek-ai/dsh@0.1.5-rc.2 --profile web --dump-config
npx @deepseek-ai/dsh@0.1.5-rc.2 web

Restart Harness after installing or updating the bundle. Pin @sesori/pr-monitor-deepseek@X.Y.Z for deliberate upgrades. Package details: deepseek/README.md.

Hermes

Needs Node.js 18 or newer on the Hermes backend.

hermes plugins install sesori-ai/pr-monitor-plugin/hermes
hermes plugins enable pr-monitor

Restart Hermes afterwards. Node.js and the logged-in gh must be on the backend's PATH, not just your laptop's. If your profile restricts tools, enable the pr-monitor toolset.

Background monitoring works in Hermes Desktop and TUI with the default dashboard.turn_isolation: false. The Hermes CLI, messaging gateways, ACP clients, and Desktop with turn isolation switched on can only use the manual ready and unready actions. Details are in the Hermes README.

Check it works

Ask your agent to list its PR monitors. It should answer that none are active. Then open a PR and ask the agent to monitor it, or call the tool yourself:

pr_monitor(action: "start", pr: "owner/repo#123")

Full PR URLs work too. Every host ships a monitor-pr skill, so after a PR is opened the agent usually starts the monitor on its own.

What you get

Once a monitor is running, the agent ends its turn and waits. PR Monitor does the polling. When there is something worth knowing, a report like this appears in the conversation:

[PR Monitor] [acme/widgets#42] — "Fix reconnect backoff"
- CI: passing (5/5)
- Mergeable: MERGEABLE
- [comment:inline] ACTION REQUIRED: 1 thread received a new relevant comment
- Ready for human review: NO — feedback awaits an agent reply

Fewer, better messages. Routine activity is batched. If CI is still running, the report waits for it so you see one summary instead of a drip of notifications.
Bad news travels fast. A new CI failure, a merge conflict, or the PR merging or closing is reported at the next poll.
Facts, not transcripts. Reports name authors, counts, and statuses. They never quote comment bodies.
Hands-off handoff. When CI passes (or the repository has no CI), the PR is mergeable, and the agent has replied to all feedback, PR Monitor adds the ready-for-human-review label. New commits or feedback take it off again. Agent replies start with a hidden  marker so the monitor can tell them apart from human comments.
Optional auto-merge. Off by default. When on, PR Monitor makes one careful squash-merge attempt after it marks the PR ready itself, either automatically or through mark_ready. A ready label added by anyone else never triggers a merge. Read auto-merge before turning it on.
Stops by itself when the PR merges or closes.

Tool actions

The pr_monitor tool is the same on every host:

Action	Target	What it does
`start`	one PR	Start watching and, unless `announceOnStart` is off, report the current state.
`stop`	one PR or `all`	Stop watching.
`flush`	one PR or `all`	Send a full report right now.
`status`	none	List the monitors this conversation owns.
`mark_ready`	one PR	Add the ready label, accepting the PR as it is.
`unmark_ready`	one PR	Remove the ready label.

mark_ready is for feedback you have looked at and decided needs no reply, such as a bot comment. unmark_ready is not a permanent hold: if the PR later looks clean again, the label comes back.

Configuration

Defaults are sensible and no config file is needed. To change them, create ~/.config/pr-monitor/config.json for yourself or .pr-monitor.json in a repository. DeepSeek Harness intentionally ignores project config because its plugin API has no project-trust signal. The settings people change most:

{
  "debounceMinutes": 2,
  "readyLabel": "ready-for-human-review",
  "autoMerge": false
}

The configuration guide lists every setting, where files are looked up, and how auto-merge keeps itself safe.

Good to know

Monitors live in memory and belong to the conversation that started them. Quitting the host loses them, so ask the agent to start them again after a restart.
The monitor owns the waiting. The agent should not sleep, poll, schedule checks, or call status and flush in a loop. Reports arrive on their own.
Reports reach the agent differently on each host, and some hosts have extra limits. See the host guide.
