Worktrunk Tend CI

Project-specific guidance for tend workflows running on worktrunk (a Rust CLI for managing git worktrees). The generic skills (/tend-ci-runner:run-tend, /tend-ci-runner:review, /tend-ci-runner:triage, etc.) provide the workflow framework; this skill adds worktrunk conventions.

Filing issues in other repos

Standing exception granted: file directly in agent-equipped targets (per Filing issues in the bundled /tend-ci-runner:act-in-other-repos skill) without asking permission here first. The default rule (open an issue here asking permission first) still applies when the target shows no agent signals.

Codecov Monitoring

After required CI checks pass, poll codecov/patch — it is mandatory despite being marked non-required:

for i in $(seq 1 5); do
  CODECOV=$(gh pr checks <number> 2>&1 | grep 'codecov/patch' || true)
  if echo "$CODECOV" | grep -q 'pass'; then
    echo "codecov/patch passed"; exit 0
  elif echo "$CODECOV" | grep -q 'fail'; then
    echo "codecov/patch FAILED"; exit 1
  fi
  sleep 60
done

If codecov fails locally, investigate with task coverage and cargo llvm-cov report --show-missing-lines | grep <file>.

Investigating codecov failures in CI

task and cargo-llvm-cov are not installed in the tend-setup action. Don't try to cargo install them in the sandbox — past attempts at source-compiling installs cascaded into bash-tool interrupts that blocked even pwd and echo. Instead, query Codecov directly, following tests/AGENTS.md → Coverage Investigation for the endpoints and their traps. The scratch paths there and below go to ${TMPDIR:-/tmp} — write new ones the same way.

If the Codecov API markers aren't enough, download the code-coverage-report artifact from the PR head's coverage workflow run — it contains a cobertura.xml with per-line hit counts:

REPO=$(gh repo view --json nameWithOwner --jq '.nameWithOwner')
# Find the coverage run on the PR head SHA:
CI_RUN=$(gh api "repos/$REPO/commits/<sha>/check-runs" --jq '.check_runs[] | select(.name == "code-coverage") | .details_url | capture("runs/(?<id>[0-9]+)") | .id')
# List artifacts, then download the coverage one:
gh api "repos/$REPO/actions/runs/$CI_RUN/artifacts" --jq '.artifacts[] | {name, id}'
gh api "repos/$REPO/actions/artifacts/<id>/zip" > "${TMPDIR:-/tmp}/coverage.zip"
unzip -q "${TMPDIR:-/tmp}/coverage.zip" -d "${TMPDIR:-/tmp}/coverage"
