What it tells the agent to use

found in the instruction text
Bash runs shell commands — read the instruction before connecting

The instruction itself

9 sections, as written by the author

The current user message contains an <agent-think-run> envelope with

repository, issue, instruction, requested-by, and (when available)

trigger-comment-id.

Use those values exactly. Never infer or substitute another target from examples,

workspace contents, GitHub searches, or concurrent issues. If the envelope or a

required field is absent, stop without cloning/editing/pushing/posting and return a

structured skipped result. When trigger-comment-id is present, your first

container action is the liveness reaction:

gh api repos/<repository>/issues/comments/<trigger-comment-id>/reactions \
  -f content=rocket

Produce a focused fix PR, authored as yourself — the agent-think GitHub App.

Do not impersonate any user.

The instruction is the free-form text the user typed after @agent-think (it

may be empty). Treat it as a direct instruction — e.g. constraints

on the fix, a preferred approach, or a pointer to the suspect area — and weight

it highly, but stay within the scope of the issue.

All gh, git, npm, curl, and wrangler commands must run on the

container backend (bash({ command, backend: "container" })) — the shell

backend has no real binaries or network. gh is already authenticated as the

app; use it directly (no token handling). Work under /workspace; put long

logs and disposable scratch files in container-local /temp.

0. Clone the repo

Clone the target repo directly under /workspace using its repository name

(cloudflare/agents/workspace/agents):

REPO_DIR="/workspace/$(basename <repo>)"
if [ ! -d "$REPO_DIR/.git" ]; then
  git clone https://github.com/<repo>.git "$REPO_DIR"
fi
cd "$REPO_DIR"

1. Gather everything known

gh issue view <issueNumber> --repo <repo> --json title,body,labels,author,comments

Read the body and every comment. In particular look for a comment from the

prior repro run (@agent-think repro): it may contain a minimal reproduction, a live URL,

observed-vs-expected behavior, and a root-cause hypothesis pointing at a

file/line. Use it as your starting point — do not re-derive what is already

known.

Decide if this is fixable in one shot. If the issue is a feature request

needing design, is too vague, spans many subsystems, or you cannot locate a

confident root cause, stop: return prOpened: false, skipped: true, and a

summary explaining why. Post a brief, polite comment saying the pr-agent is

skipping it and what additional detail would help; begin it with

Requested by @<requestedBy> when the run envelope has a requester.

2. Locate the root cause

With the repo cloned at $REPO_DIR, read the relevant code in

packages/agents, packages/think, etc. Confirm the hypothesis (or form your

own) by reading the actual implementation. Identify the smallest change that

fixes the reported behavior.

3. Branch and set commit identity

Commit as the agent-think app itself:

git config user.name "agent-think[bot]"
git config user.email "agent-think[bot]@users.noreply.github.com"
BRANCH="fix/issue-<issueNumber>-$(date +%s)"
git checkout -b "$BRANCH"

4. Make the fix

  • Smallest correct change. Fewest files. Match the existing code style.
  • Add or update a test that fails before the fix and passes after, when the

area is testable.

  • Add a changeset if the repo uses them (.changeset/) for a user-facing fix:

create a markdown file following the existing format in .changeset/.

  • Update examples and docs when the change affects behavior they show:

if an examples/* app or a docs//README section demonstrates the code you

touched, keep it truthful in the same PR.

5. Verify

Install and run the affected package's checks (monorepo uses pnpm + Nx):

# NOISY commands (installs, builds, test suites) MUST be redirected to a
# container-local /temp file and tailed — streaming megabytes of live output
# through the session can kill it irrecoverably:
mkdir -p /temp
CI=1 pnpm install --frozen-lockfile --reporter=append-only \
  > /temp/install.log 2>&1 || (tail -40 /temp/install.log; false)
tail -20 /temp/install.log
# Prefer scoped/affected runs; fall back to package scripts.
pnpm -w exec oxfmt --check . || pnpm -w exec oxfmt --write .
pnpm -w exec oxlint . || true
# Run the relevant package's typecheck + tests, redirected the same way:
pnpm --filter <package> typecheck > /temp/typecheck.log 2>&1; tail -30 /temp/typecheck.log
pnpm --filter <package> test > /temp/test.log 2>&1; tail -40 /temp/test.log

(/temp is outside the /workspace mount and is not synchronized.)

Record whether tests passed in testsPassed. If you cannot make tests pass and

the failure is your change's fault, fix it; if tests are unrelated/flaky, note

that in the PR body. Do not open a PR whose own new test fails.

6. Deploy a live demo of the PR

Every PR ships with a temporary deployment demoing the change so reviewers

click a link and see the fixed behavior instead of imagining it.

  • Build the fixed package(s) in the repo and pack them:
pnpm --filter <package> build
(cd packages/<package> && npm pack --pack-destination /workspace)   # -> /workspace/<package>-x.y.z.tgz
  • Build a minimal demo app in /workspace/demo-<issueNumber> that exercises

the fixed path. Follow the activated reproduce skill's **"Minimal frontend

(required)"** recipe — same 7 files — but install the packed tarball so the

demo runs YOUR fix:

npm install /workspace/<package>-x.y.z.tgz

If the repro run left a repro/issue-<issueNumber> branch, start from that

project instead and just swap the dependency to the packed build — the same

UI then demos broken-before / fixed-after.

  • Deploy and verify the fix is actually observable in the page:
npm run deploy      # vite build && wrangler deploy --temporary
curl -sS -i "<demoUrl>/" | head -5

Capture the https://...workers.dev URL as demoUrl. Ignore the claim URL

the deploy prints — it never goes in a PR.

Use judgment: changes with no runtime surface (docs-only, types-only, CI) skip

the demo — say so in the PR body ("no runtime surface to demo") rather than

deploying something meaningless.

7. Commit, push, open the PR

git status --short
git add -A
git commit -m "fix: <concise description> (#<issueNumber>)"
git push -u origin "$BRANCH"

gh pr create --repo <repo> \
  --base main \
  --head "$BRANCH" \
  --title "fix: <concise description> (#<issueNumber>)" \
  --body-file /temp/pr-body.md

Write the PR body outside the checkout at /temp/pr-body.md. It must include:

  • Requested by @<requestedBy> near the top, using the exact sanitized

requested-by mention from the run envelope (omit only when it is unknown).

  • Closes #<issueNumber> so the issue auto-links.
  • What was wrong (root cause, citing the file/line).
  • What changed and why this is the minimal fix.
  • Testing: what you added/ran and the result.
  • Demo: phrase it exactly like "Demo URL (expires after 60 mins):

<demoUrl>" plus one line of click instructions and a note that it runs the

packed build from this branch. If skipped, one line on why.

  • A link back to the repro-agent's reproduction (comment and/or the

repro/issue-<issueNumber> branch) if one exists.

  • A "🤖 generated by the pr-agent — please review carefully" footer.

Capture the PR URL and branch name.

Do not post an acknowledgement or "opened a PR" comment on the issue. The

PR links back to the issue via Closes #<issueNumber>. The only case where you

comment is the skip path in the Gather everything known step (no PR

exists to show).

8. Return the structured result

Return exactly:

  • prOpened (boolean)
  • skipped (boolean)
  • summary (string — one or two sentences)
  • prUrl (string, optional)
  • branch (string, optional)
  • testsPassed (boolean, optional)
  • demoUrl (string, optional)

How to use it

Copy the folder

Take cloudflare/open-pr from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npm. Without those the skill loads but fails at the first command.
