Kill the Standup

Read yesterday's Linear issues and GitHub commits. Format a standup update. Post it to Slack.

Step 1: Setup Check

Confirm required env vars are set:

echo "LINEAR_API_KEY: ${LINEAR_API_KEY:+set}"
echo "SLACK_WEBHOOK_URL: ${SLACK_WEBHOOK_URL:+set}"
echo "GITHUB_REPO: ${GITHUB_REPO:-not set}"
echo "GITHUB_USERNAME: ${GITHUB_USERNAME:-not set}"

If LINEAR_API_KEY is missing: Stop. Tell the user: "LINEAR_API_KEY is required. Get it from Linear → Settings → API → Personal API keys. Add it to your .env file."

If SLACK_WEBHOOK_URL is missing: Stop. Tell the user: "SLACK_WEBHOOK_URL is required. Create an Incoming Webhook at api.slack.com/apps → Your App → Incoming Webhooks. Add it to your .env file."

If GITHUB_REPO is missing: Continue. GitHub commits will be skipped. Note this to the user.

Step 2: Fetch Linear Activity

Compute yesterday's date in ISO 8601 format (e.g. 2026-04-09T00:00:00.000Z).

Get current user ID:

curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: Bearer $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "query { viewer { id name email } }"}'

Extract the id field from the response. Store as LINEAR_USER_ID.

Fetch issues assigned to me, updated since yesterday:

curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: Bearer $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "query($since: DateTime!, $userId: ID!) { issues(first: 50, filter: { assignee: { id: { eq: $userId } } updatedAt: { gte: $since } }) { edges { node { identifier title state { name } url completedAt updatedAt createdAt } } } }",
    "variables": {"since": "YESTERDAY_ISO", "userId": "LINEAR_USER_ID"}
  }'

Categorize issues:

• completedAt is non-null → Done
• state.name is "In Progress", "Started", or "In Review" → Doing
• state.name is "Cancelled" → skip
• state.name is "Todo" or "Backlog" → skip (not worked on)

If zero issues: note "No Linear activity found for yesterday."

Step 3: Fetch GitHub Commits

Skip this step silently if GITHUB_REPO is not set.

If GITHUB_REPO is set:

gh api "repos/$GITHUB_REPO/commits?author=${GITHUB_USERNAME:-$(gh api user --jq .login)}&since=YESTERDAY_ISO&per_page=30" \
  --jq '[.[] | {message: .commit.message, url: .html_url}]'

Process commits:

• Extract the first line of each commit message (everything before the first newline)
• Skip merge commits: drop any message starting with "Merge"
• Deduplicate by message text

If GITHUB_REPO is set but returns zero commits: note "No commits found yesterday."

Step 4: Format Standup

Read references/standup-format.md in full before writing.

Produce the standup in this exact structure:

**Done**
- [ENG-123] Title of completed issue
- fix: commit message here

**Doing**
- [ENG-124] Title of in-progress issue

**Blockers**
No blockers.

Rules from standup-format.md:

• No first-person pronouns ("I", "we")
• Past tense for Done items, present continuous for Doing items
• Each Linear item uses the [IDENTIFIER] Title format
• Each GitHub commit uses the first line of the commit message
• If no Done items: write "Nothing completed." under Done
• If no Doing items: write "Nothing in progress." under Doing
• If no blockers: write "No blockers."
• Under 200 words total

Step 5: Post to Slack or Output

Present the formatted standup to the user.

Ask: "Post this to Slack, or output only?"

On confirmation to post:

curl -s -X POST "$SLACK_WEBHOOK_URL" \
  -H "Content-Type: application/json" \
  -d '{
    "blocks": [
      {
        "type": "section",
        "text": {
          "type": "mrkdwn",
          "text": "*Standup — DATE_HERE*\n\n*Done*\nITEMS\n\n*Doing*\nITEMS\n\n*Blockers*\nITEMS"
        }
      }
    ]
  }'

Pass the body via a temp file or heredoc to avoid shell quoting issues with special characters in commit messages or issue titles:

cat > /tmp/standup-payload.json << 'ENDJSON'
{
  "blocks": [
    {
      "type": "section",
      "text": {
        "type": "mrkdwn",
        "text": "STANDUP_CONTENT_HERE"
      }
    }
  ]
}
ENDJSON
curl -s -X POST "$SLACK_WEBHOOK_URL" -H "Content-Type: application/json" -d @/tmp/standup-payload.json

After posting: "Standup posted."

On "output only": Print the standup in a code block for copy-paste.
