Agent Dispatch (DEPRECATED)

This skill is deprecated. It requires an ANTHROPIC_API_KEY with per-token API billing, which is not compatible with Max/Pro subscriptions. Use parallel agents in-session or manual spike execution instead.

Dispatches swain-design artifacts to background agents via GitHub Issues. The agent runs autonomously using anthropics/claude-code-action@v1 on a GitHub Actions runner.

Note: In projects using the trunk+release branch model (ADR-013), dispatched work targets trunk (the development branch), not release (the distribution branch).

Prerequisites

Three things must be in place before dispatch works:

1. Claude GitHub App — installed on the repo from https://github.com/apps/claude (grants Contents, Issues, Pull Requests read/write)
2. Workflow file — .github/workflows/claude.yml (or agent-dispatch.yml) with the claude-code-action step
3. ANTHROPIC_API_KEY repo secret — API key (not Max/Pro subscription; per-token billing required)

Step 0 — Preflight check

Run this before every dispatch. If any check fails, stop and show the setup instructions.

# 1. Check gh auth
gh auth status 2>/dev/null || { echo "FAIL: gh not authenticated"; exit 1; }

# 2. Check workflow file
WORKFLOW_FILE=""
for f in .github/workflows/claude.yml .github/workflows/agent-dispatch.yml; do
  [[ -f "$f" ]] && WORKFLOW_FILE="$f" && break
done

# 3. Check API key secret
OWNER_REPO="$(gh repo view --json nameWithOwner -q .nameWithOwner)"
HAS_KEY=$(gh api "repos/${OWNER_REPO}/actions/secrets" --jq '.secrets[].name' 2>/dev/null | grep -c ANTHROPIC_API_KEY || true)

If workflow file is missing, show:

Dispatch setup required. No workflow file found. Create .github/workflows/claude.yml: ``yaml name: Claude Code on: repository_dispatch: types: [agent-dispatch] issue_comment: types: [created] pull_request_review_comment: types: [created] issues: types: [opened, assigned] jobs: claude: if: | (github.event_name == 'issue_comment' && contains(github.event.comment.body, '@claude')) || (github.event_name == 'pull_request_review_comment' && contains(github.event.comment.body, '@claude')) || (github.event_name == 'issues' && contains(github.event.issue.body, '@claude')) runs-on: ubuntu-latest permissions: contents: write issues: write pull-requests: write id-token: write steps: - uses: actions/checkout@v4 - uses: anthropics/claude-code-action@v1 with: anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }} `` Then commit and push before retrying dispatch.

If API key secret is missing, show:

Missing ANTHROPIC_API_KEY repo secret. Set it with: gh secret set ANTHROPIC_API_KEY --repo {owner}/{repo} Note: This must be an API key (per-token billing), not a Max/Pro subscription token.

Dispatch workflow

Step 1 — Resolve the artifact

Parse the user's request to identify the artifact ID (e.g., SPEC-025, SPIKE-007).

ARTIFACT_ID="SPEC-025"  # from user input
ARTIFACT_PATH="$(find docs/ -path "*${ARTIFACT_ID}*" -name "*.md" -print -quit)"

If not found, report the error and stop.

Step 2 — Read the artifact

Read the full artifact content. This becomes the issue body.

Step 3 — Read dispatch settings

Check swain.settings.json for dispatch configuration:

jq -r '.dispatch // {}' swain.settings.json 2>/dev/null

Defaults:

• model: claude-sonnet-4-6
• maxTurns: 15
• labels: ["agent-dispatch", "swain"]
• autoTrigger: true

Step 4 — Create the GitHub Issue

gh issue create \
  --title "[dispatch] ${ARTIFACT_TITLE}" \
  --body "$(cat <<EOF
## Dispatched Artifact: ${ARTIFACT_ID}

This issue was created by `swain-dispatch` for background agent execution.

### Instructions

Implement the artifact below. Follow the acceptance criteria. Create a PR when done.

---

${ARTIFACT_CONTENT}
EOF
)" \
  --label "agent-dispatch" --label "swain"

Capture the issue number from the output.

Step 5 — Trigger the workflow

If autoTrigger is true (default):

OWNER_REPO="$(gh repo view --json nameWithOwner -q .nameWithOwner)"
gh api "repos/${OWNER_REPO}/dispatches" \
  -f event_type="agent-dispatch" \
  -f client_payload[artifact]="${ARTIFACT_ID}" \
  -f client_payload[issue_number]="${ISSUE_NUMBER}" \
  -f client_payload[model]="${MODEL}" \
  -f client_payload[max_turns]="${MAX_TURNS}"

Step 6 — Report

Tell the user:

Dispatched ${ARTIFACT_ID} to background agent. Issue: ${ISSUE_URL} Workflow will run on the next available runner. Monitor progress in the issue comments.

Manual dispatch

If the user prefers manual dispatch (or autoTrigger is false), skip Step 5 and tell them:

Issue created: ${ISSUE_URL} To trigger the agent, comment @claude on the issue.

Checking dispatch status

When the user asks about dispatch status:

gh issue list --label agent-dispatch --state open --json number,title,updatedAt

Show open dispatch issues with their last update time.

Trigger timing

The Claude Code Action workflow fires on different GitHub events depending on how @claude is mentioned:

Gotcha: If the workflow file didn't exist when the issue was created, the issues.opened event was missed. In that case, add a follow-up comment containing @claude to trigger via issue_comment.created instead.

The default dispatch workflow (Step 4 + Step 5) uses repository_dispatch which is independent of @claude mentions. The timing gotcha only applies when:

• Using manual dispatch (Step 5 skipped)
• The workflow relies on issues.opened or issue_comment.created events
