Create a merge request (GitCode)

Project-local skill for ScienceDiscovery.

Read CONTRIBUTING.md first — Opening a merge request and Repositories carry the process and the reason changes are proposed on GitCode rather than GitHub. Command surface: .agents/skills/gitcode/SKILL.md. Pipeline internals — which platform runs which layer, the workflow files, run logs, and failure attribution: .agents/skills/ci/SKILL.md.

Rules

1. The layers are a gate, not a suggestion. CONTRIBUTING says run all three; do not open a merge request without them.
2. Target openJiuwen/sciencediscovery on gitcode.com. GitHub is a synced mirror with its own SHAs; a merge request opened there is in the wrong place. Push the task branch only to the operator's own GitCode fork (commonly a local remote named gitcode-fork → git@gitcode.com:<gitcode-login>/sciencediscovery.git). Resolve <gitcode-login> from gitcode auth status --json; do not hard-code a person. Do not git push origin <branch> or create the branch on the upstream repository. Create the merge request with --head <gitcode-login>:<branch> --base main.
3. Read the merge request back after creating it. The create response is thin and will not tell you whether it landed as intended.
4. Say what was verified in the body, with the actual numbers. "Tests pass" is not reviewable; "382 API tests, 100 runner tests, mocked E2E 5 passed / 2 skipped" is.
5. E2E is a user-perspective journey, not a browser-only gate. Report affected product paths through the UI, public API, CLI, or local stack. Implementers add or improve relevant journeys with behavior changes (or identify and rerun existing coverage), including backend-only changes to Runs, tools, versioned state, artifacts or permissions. Do not defer this coverage until the PR is opened.

Run the layers first

No pipeline runs the full set — CodeArts runs ci:ut:host and ci:st on the merge request, GitHub runs the rest on the mirror (see the ci skill) — so the local run is the only complete check a reviewer gets.

bwrap --ro-bind / / --dev /dev true && echo sandbox ok      # ci:ut and ci:e2e need it
CI_RESULTS_DIR=.tmp/ci-results CI_RUNTIME_DIR=.tmp/ci-runtime pnpm ci:ut   # not ci:ut:host
CI_RESULTS_DIR=.tmp/ci-results CI_RUNTIME_DIR=.tmp/ci-runtime pnpm ci:st
CI_RESULTS_DIR=.tmp/ci-results CI_RUNTIME_DIR=.tmp/ci-runtime pnpm ci:e2e

• Run them on the commit you will push. When the working tree carries anything else, use a clean worktree of that commit (git worktree add --detach .worktrees/<name> <sha>); the layers install and build there themselves.
• Each layer leaves run.log and a summary under CI_RESULTS_DIR/<layer>/. With a relative CI_RESULTS_DIR, ci:e2e writes its journey reports below .e2e/.tmp/… instead, because Playwright runs from .e2e/.
• Collect the numbers for the body: the per-package # pass / # skipped lines in the UT run.log, the paper, gateway, binary, and memory-graph totals, the ST smoke line, and the E2E discovered / passed / failed / skipped split. A skipped or BLOCKED E2E case is not a pass; the e2e-testing skill owns that reporting.
• pnpm ci:e2e runs only the mocked browser subset. Also run the relevant API/CLI/local-stack journeys through start-stack.sh or a documented equivalent product entry point and the supported client interface. An in-process adapter smoke or package test is not E2E; do not relabel ci:st. Keep the CI layer commands unchanged and report each additional driver separately. Browser coverage remains necessary for changed UI behavior.
• When a layer fails, attribute it before touching anything: run the same layer on unmodified origin/main in a separate detached worktree. An identical failure is pre-existing — state it in the body with the step, the error, and the baseline run, and leave the fix to its own merge request. A failure only on your commit is yours: fix it and rerun that layer on the new commit.
• Never weaken an assertion or skip a layer to get green. If a layer cannot run on this host (no sandbox), say which and why in the body; ci:ut:host is not a substitute for ci:ut.

The process

CONTRIBUTING.md owns it — the branch and push commands and the pr create invocation. Follow it. Task branches live on the operator's own fork only (git push -u gitcode-fork <branch>). CodeArts still runs on the resulting merge request; pass --head <gitcode-login>:<branch>. Do not open the source branch on openJiuwen/sciencediscovery. This skill covers what the CLI does not make obvious once you get there.

Body shape

<One paragraph: what changes and why. Lead with the problem, not the patch.>

## <Each substantive change>
<What it does, and the reasoning a reviewer cannot reconstruct from the diff.>

## Validation
<Layer results with numbers. Name anything not covered and why.>

## E2E user journeys
<PASS / FAIL / BLOCKED; tested SHA; browser / API / CLI / local stack;
scenario → expected outcome → actual outcome; startup and test commands;
passed / failed / blocked / skipped counts and failure attribution.>
<Browser: journey reports and screenshots for UI changes. API/CLI: redacted
request/response summaries, exit codes, observable Run/artifact state and logs;
do not fabricate page screenshots.>

Only when no user-observable product path is affected (for example a pure documentation/comment change) may the E2E section say not applicable, with a concrete reason. Backend-only / no new UI is not an exemption. Missing credentials, startup failures or absent coverage must be reported as BLOCKED or a coverage gap, not not-applicable or PASS. This applicability decision does not remove the CI gates above. Evidence must be public-safe: no credentials, local/private paths, or links that a repository reader cannot access.

Mark a merge request that must not land — a CI experiment, a spike — in both the title and the body, and say what to delete before it could be merged.

After it opens

Two bots respond within a minute or two:

• openJiuwen-bot — a welcome comment, the CLA result (CLA 签署成功, label openJiuwen-cla/yes), then The pipeline(pipeline number:<n>) is running with the label ci-running. When the parent workflow in .codearts/workflow/codearts-pipeline.yml finishes, the bot posts the result that workflow rendered (see below) and adds ci-successful or ci-failed.
• atomgit-bot — a change summary, AI 代码检视正在进行中, a command guide, and the review verdict (代码审查 ✅ 未发现问题 or findings). /ai review and /ai summary re-trigger it from a comment.

The 流水线 tab on the PR page shows the same CodeArts run; there is no separate .gitcode/workflows/ Actions pipeline. To run CI again without pushing, comment rerun on the PR.

Reading the result

The result comment is rendered by the parent workflow, and the bot posts it unchanged: ✅ 流水线 <run_id> 执行成功 or ❌ … 执行失败, the /pull/<n>/check link, then one table — 代码检查 (SCA / Anti-poison / CodeCheck / Blacklist, each with its own status), UT, ST, and the x86_64 / aarch64 debug binary jobs, each PASSED or FAILED — and the rerun hint. The UT and ST rows are the workflow's ut and st jobs, the same ci:ut:host and ci:st entry points run locally. Judge each code-check child from its own row; do not treat one successful sibling or the parent summary as evidence that every child passed.

• 公开日志 in a UT/ST row links the OBS run.log of that job. A cell that says 查看构建日志（公开测试日志未生成） means the job died before its upload step (checkout, provisioning), so no test ran; open the Checks page. Log locations and CodeArts internals: the ci skill's CodeArts reference.
• Labels: ci-running while the run is in progress, then ci-successful or ci-failed. Judge a run by its latest result comment, not by the label set.
• Read it back before responding. gitcode pr view --comments --json nests the PR under .pull_request (see the gitcode skill); for label and state history use the REST API:

gitcode pr view <n> -R openJiuwen/sciencediscovery --comments --json
gitcode api repos/openJiuwen/sciencediscovery/pulls/<n>              # labels, state, head/base SHAs
gitcode api repos/openJiuwen/sciencediscovery/pulls/<n>/operate_logs # add/delete label, force-push, close events

If a check fails, find out whether the change caused it. Compare against other open merge requests before assuming ownership — a step that fails identically on every open request is pre-existing, and saying so with evidence is more useful than a speculative fix.

Troubleshooting

Symptom	Meaning
create returns a number but no html_url	Normal. Read it back with pr view.
409, "same source branch already has an open MR"	Read that merge request first; it may be this attempt, an earlier one, or someone else's. Never rename the branch to dodge it.
A GitHub remote looks diverged with identical files	The two hosts have separate histories. Compare trees, not SHAs.
CI red immediately, 1s, empty log	Nothing ran — infrastructure, not the change. See the ci skill.
A UT/ST cell says 查看构建日志（公开测试日志未生成）	The job died before its upload step (checkout, provisioning); open the Checks page, the test itself never ran.
ci-running is still on the PR after the result comment	The publisher adds the final label but has not removed ci-running; the latest result comment is authoritative.
The PR commit(s) can not be got after a push	The PR's head is already contained in its base (empty diff), so the bots cannot read commits or a diff; no result is published for that run.
