phx-watch-prWatch an Elixir/Phoenix PR for new review comments (bot + human) and CI results via a background watcher that wakes Claude only on real events.
Phx Watch PR is an agent skill from oliver-kriska/claude-elixir-phoenix. Watch an Elixir/Phoenix PR for new review comments (bot + human) and CI results via a background watcher that wakes Claude only on real events. Use after opening a PR or pushing, while waiting on CI or reviewers.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/watcher-mechanics.md` and `scripts/watch-pr.sh`).
It sits in AI & LLM Engineering, covering LLM observability. It works with Elixir. The repository describes itself as: Claude Code plugin for Elixir/Phoenix/LiveView — 26 specialist agents, Iron Laws enforcement, and Tidewave MCP integration. Plan features with parallel research agents, execute… The licence is MIT.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 9767a82. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 1 file in scripts/ (Shell), which the agent can run.
Shell commands in SKILL.md call:
ghjqcodexFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Phx Watch PR loads about 1.9k tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 811 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

This skill also uses 2 other files; get the full folder from GitHub.Watch a PR's reviews, comments, and CI with a background watcher that wakes Claude ONLY on real events — no foreground sleep loops, no context bloat. The watcher polls quietly in its own process; nothing enters context until something genuinely changed.
/skill:phx-watch-pr 42 # watch reviews + comments + checks
/skill:phx-watch-pr 42 --checks-only # CI only (delegates to gh pr checks --watch)
/skill:phx-watch-pr 42 --fix # on actionable review, draft fixes too
/skill:phx-watch-pr 42 --codex # + request Codex cloud review, loop until clean
/skill:phx-watch-pr 42 --codex --codex-rounds 2 # cap re-review rounds (default 3)sleep in the session — use the
background watcher (Monitor / run_in_background). Foreground polling
bloats context and straddles the 5-min cache TTLgh JSON. The watcher
emits one-line events; read .claude/watch/pr-{n}.jsonl on demand/skill:phx-pr-review
for responses; show drafts and get approval. ONE exception: passing
--codex IS the consent to post the @codex review trigger comment
(and its per-round re-requests) — nothing else is ever auto-posted--codex); always stop on terminal state. Codex rounds are bounded by
--codex-rounds (default 3) — each round costs cloud quotaExtract PR number (from number or URL — URL also yields the repo). Detect
--checks-only / --fix / --codex / --codex-rounds N. Baseline
timestamp = now; events are "new since baseline", so old reviews don't
re-fire.
With --codex, the default is to POST @codex review — the flag IS
that consent (Iron Law 4). Skip the trigger ONLY when the connector bot
(chatgpt-codex-connector[bot]) has itself reacted to / reviewed the
current head SHA. The repo's CI "Codex" check and any local codex exec /
/skill:phx-review --codex / /skill:phx-codex-loop run are DIFFERENT mechanisms from
the GitHub connector — they NEVER satisfy the skip. When unsure, post. The
connector auto-registers PRs on ready (its absence surfaces later as
codex_timeout), so check ITS reactions before posting a redundant trigger:
HEAD_AT=$(gh api "repos/{owner}/{repo}/commits/$(gh pr view {n} --json headRefOid -q .headRefOid)" --jq .commit.committer.date)
BOT=$(gh api "repos/{owner}/{repo}/issues/{n}/reactions" | jq -r --arg t "$HEAD_AT" \
'[.[] | select(.user.login == "chatgpt-codex-connector[bot]" and .created_at >= $t) | .content] | unique | join(",")')(gh api --jq accepts no --arg — pipe through standalone jq.)
Definitive check first: a connector-bot comment or review containing
Reviewed commit: {sha} that matches the current head sha means that
state IS reviewed (clean if it says "Didn't find any major issues") —
trust it over timestamps, which are client-set and can skew. Then:
| Connector-bot signal on current head | Action |
|---|---|
+1 reaction | Connector already reviewed this head clean — no trigger, no codex round; watch CI/humans only |
eyes + a codex review already submitted since $HEAD_AT | Findings already posted — skip the watch; run the codex_review action (Step 3) now |
eyes only | Review in flight — do NOT post; export WATCH_CODEX=1 WATCH_CODEX_SINCE=$HEAD_AT (no trigger id) and watch |
| none (or reactions predate head) | Post the trigger and capture its id: |
TRIGGER_ID=$(gh api --method POST "repos/{owner}/{repo}/issues/${PR}/comments" \
-f body="@codex review" --jq '.id')Export WATCH_CODEX=1 WATCH_CODEX_TRIGGER_ID=$TRIGGER_ID to the watcher
env and set MAX_DURATION 7200. Round counter starts at 1.
--checks-only PathNo custom poller needed — gh pr checks --watch blocks until all checks
finish, then exits. Run via Bash with run_in_background: true:
gh pr checks {n} --watch --fail-fast --interval 10Exit code is the signal: 0 = pass, 1 = fail, 8 = pending. On exit,
report the conclusion; on failure, offer /skill:phx-investigate with the
failing job log (gh run view {run-id} --log-failed).
Start the Monitor tool (preferred — streams each event line back) on:
scripts/watch-pr.sh {n} reviews,comments,checksMonitor is a deferred tool — load its schema FIRST via ToolSearch
(select:Monitor); calling it blind fails with InputValidationError
(use only the params its schema lists). A Monitor watch ends within 30 min
(10 in -p runs, CC 2.1.271+), so export WATCH_SEGMENT=1740 (540 in -p)
and set timeout_ms = 1800000 (600000). The script emits rearm before that.
Where Monitor is unavailable
(Bedrock/Vertex/Foundry), run the same script via Bash
run_in_background: true — it exits on the first terminal event instead.
Stay idle or keep working until an event lands.
| Event | Action |
|---|---|
review / comment (actionable) | Summarize the delta; with --fix draft fixes + mix compile && mix test; route reply drafting to /skill:phx-pr-review {n} |
check conclusion failure | Offer /skill:phx-investigate on the failing job |
codex_ack | Note "codex is reviewing (~15–20 min on large PRs)"; keep waiting |
codex_review | Stop the watcher. Run /skill:phx-pr-review {n} --bots-only (fix → reply → resolve; user approves and pushes). If rounds < --codex-rounds: post @codex review again, restart watcher with the new trigger id, round+1. Else: report remaining findings, stop |
codex_clean | Codex is clean (👍 reaction OR a "Didn't find any major issues" bot comment). If checks also green → terminal success "codex + CI clean"; else keep watching CI |
codex_timeout | Inform: repo likely lacks the Codex connector; continue as a plain watch |
rearm | Not terminal. Start the same command again with WATCH_RESUME=1 added — it restores baseline, seen events and check state from the delta file |
merged / pr_closed / watchdog / watch_error | Stop, report final state |
A codex_review whose /skill:phx-pr-review --bots-only fetch finds zero
unresolved codex threads also counts as clean (summary-only review).
The watcher self-terminates on terminal states. To stop early: TaskStop
the background task or cancel the monitor.

Watch an Elixir/Phoenix PR for new review comments (bot + human) and CI results via a background watcher that wakes Claude only on real events. Phx Watch PR is an agent skill from oliver-kriska/claude-elixir-phoenix. Watch an Elixir/Phoenix PR for new review comments (bot + human) and CI results via a background watcher that wakes Claude only on real events.
Phx Watch PR fits situations like: tasks that involve LLM observability.
Run `npx skills add oliver-kriska/claude-elixir-phoenix --skill phx-watch-pr -a claude-code`. Or copy the skill folder (targets/pi/skills/phx-watch-pr in oliver-kriska/claude-elixir-phoenix) into .claude/skills/phx-watch-pr in your project. Claude Code loads it when a task matches its description.
Run `npx skills add oliver-kriska/claude-elixir-phoenix --skill phx-watch-pr -a codex`. Or copy the skill folder (targets/pi/skills/phx-watch-pr in oliver-kriska/claude-elixir-phoenix) into .agents/skills/phx-watch-pr in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add oliver-kriska/claude-elixir-phoenix --skill phx-watch-pr -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/phx-watch-pr, .gemini/skills/phx-watch-pr, .github/skills/phx-watch-pr and .opencode/skills/phx-watch-pr in your project.
Going by SKILL.md and its folder, Phx Watch PR needs a shell for the scripts in its folder and the command-line tools its instructions call (gh, jq and codex). Our summary lists: A Bash shell.
SKILL.md contains no URLs. Its commands use gh, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Phx Watch PR is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.9k tokens (SKILL.md is roughly 7.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.7k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Phx Watch PR: Elixir Architect (maxim-ist/elixir-architect, 145 stars), Phoenix Framework (podlove/radiator, 136 stars), Elixir Expert (pass-agent/loomkin, 181 stars) and Usage Rules (bradleygolden/claude-marketplace-elixir, 176 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
