auto-lambda-env

You set Lambda environment variables for the AI automation agents. There are 2 consolidated router Lambda functions: WI Router (work-item webhook events) and PR Router (pull-request webhook events). Values are collected interactively (secrets are never written to files). Applies all variables in a single aws lambda update-function-configuration call per function.

0. Prerequisites

Read .ai/automation/infra.json. Check automationProfile:

• If consumer (or legacy pr-only/pr-delegation): "This repo uses the consumer profile — Lambda environment variables are managed by the hub project. Do NOT modify Lambda env vars from this repo." STOP.

source .ai/lib/audit.sh
export AUDIT_LOG_PREFIX=infra

Pre-fill these from infra.json (don't ask for values already known):

• DYNAMODB_DEDUPE_TABLE ← storage.dynamodb.dedupe.tableName
• DYNAMODB_RATE_LIMIT_TABLE ← storage.dynamodb.rateLimits.tableName
• SQS_DLQ_URL ← storage.sqs.dlq.queueUrl
• ADO_DOR_PIPELINE_ID ← pipelines.dor.id (WI Router)
• ADO_DOD_PIPELINE_ID ← pipelines.dod.id (WI Router)
• ADO_BUGFIX_PIPELINE_ID ← pipelines.bugfix.id (WI Router)
• ADO_QA_PIPELINE_ID ← pipelines.qa.id (WI Router)
• ADO_DEV_PIPELINE_ID ← pipelines.devagent.id (WI Router)
• ADO_DOC_PIPELINE_ID ← pipelines.docagent.id (WI Router)
• ADO_ESTIMATION_PIPELINE_ID ← pipelines.estimation.id (WI Router)
• ADO_PR_ANSWER_PIPELINE_MAP ← JSON map of repo→pipeline-id (PR Router)
• ADO_ORG_URL ← adoOrg (PR Router)
• MY_IDENTITIES ← from infra.json if set (PR Router)

1. Collect Secrets

Ask these one at a time — these cannot be pre-filled from infra.json:

ADO Personal Access Token? (secret — Lambda env var ADO_PAT) This PAT needs: Work Items read, Code read, Pull Requests read+contribute, Project read.

Webhook basic auth username? (Lambda env var BASIC_USER) Example: automation-webhook. Must match what you'll set in ADO Service Hooks.

Webhook basic auth password? (secret — Lambda env var BASIC_PASS) Suggest generating: openssl rand -base64 24

Webhook secret? (secret — Lambda env var WEBHOOK_SECRET) Suggest generating: openssl rand -base64 32

DoR trigger tag? (Lambda env var TAG_GATE_DOR — WI Router) Tag name that triggers the DoR agent. Example: AI-TRIGGER. Default: <UPPERCASE-PREFIX>-AI-TRIGGER

DoD trigger tag? (Lambda env var TAG_GATE_DOD — WI Router) Default: KAI-DOD-AUTOMATION

BugFix trigger tag? (Lambda env var TAG_GATE_BUGFIX — WI Router) Default: KAI-BUGFIX-AUTOMATION

QA trigger tag? (Lambda env var TAG_GATE_QA — WI Router) Default: KAI-QA-AUTOMATION

DevAgent trigger tag? (Lambda env var TAG_GATE_DEV — WI Router) Default: KAI-DEV-AUTOMATION

DOCAgent trigger tag? (Lambda env var TAG_GATE_DOC — WI Router) Default: KAI-DOC-AUTOMATION

Estimation trigger tag? (Lambda env var TAG_GATE_ESTIMATION — WI Router) Default: KAI-ESTIMATION-AUTOMATION

2. Apply to WI Router Lambda

The WI Router (<PREFIX>-WI-Router) handles all work-item webhook events and routes to the appropriate pipeline (DoR, DoD, BugFix, QA, DevAgent, DOCAgent, Estimation) based on tag gates.

WI_ROUTER_FUNC=$(python3 -c "import json; print(json.load(open('.ai/automation/infra.json'))['lambdas']['wi-router']['functionName'])")
REGION=$(python3 -c "import json; print(json.load(open('.ai/automation/infra.json'))['region'])")

aws_lambda_config "$WI_ROUTER_FUNC" \
  --environment "Variables={
    ADO_PAT=<secret>,
    BASIC_USER=<user>,
    BASIC_PASS=<secret>,
    WEBHOOK_SECRET=<secret>,
    ADO_DOR_PIPELINE_ID=<pipeline-id>,
    ADO_DOD_PIPELINE_ID=<pipeline-id>,
    ADO_BUGFIX_PIPELINE_ID=<pipeline-id>,
    ADO_QA_PIPELINE_ID=<pipeline-id>,
    ADO_DEV_PIPELINE_ID=<pipeline-id>,
    ADO_DOC_PIPELINE_ID=<pipeline-id>,
    ADO_ESTIMATION_PIPELINE_ID=<pipeline-id>,
    TAG_GATE_DOR=<tag>,
    TAG_GATE_DOD=<tag>,
    TAG_GATE_BUGFIX=<tag>,
    TAG_GATE_QA=<tag>,
    TAG_GATE_DEV=<tag>,
    TAG_GATE_DOC=<tag>,
    TAG_GATE_ESTIMATION=<tag>,
    DYNAMODB_DEDUPE_TABLE=<table>,
    DYNAMODB_RATE_LIMIT_TABLE=<table>,
    SQS_DLQ_URL=<url>
  }" \
  --region "$REGION"

3. Apply to PR Router Lambda (merge-safe)

The PR Router (<PREFIX>-PR-Router) handles all pull-request webhook events. It uses ADO_PR_ANSWER_PIPELINE_MAP (JSON map of repo→pipeline-id) for routing PR answer events to the correct pipeline.

PR_ROUTER_FUNC=$(python3 -c "import json; print(json.load(open('.ai/automation/infra.json'))['lambdas']['pr-router']['functionName'])")

aws_lambda_config "$PR_ROUTER_FUNC" \
  --environment "Variables={
    ADO_PAT=<secret>,
    BASIC_USER=<user>,
    BASIC_PASS=<secret>,
    WEBHOOK_SECRET=<secret>,
    ADO_ORG_URL=<adoOrg>,
    ADO_PR_ANSWER_PIPELINE_MAP=<json-map>,
    MY_IDENTITIES=<identities>,
    DYNAMODB_DEDUPE_TABLE=<table>,
    DYNAMODB_RATE_LIMIT_TABLE=<table>,
    SQS_DLQ_URL=<url>
  }" \
  --region "$REGION"

Important: aws lambda update-function-configuration replaces ALL env vars. Always read current env vars first and merge changes, preserving existing secrets and table names.

4. Verify

# List env var KEYS only (not values — never print secrets)
for FUNC in "$WI_ROUTER_FUNC" "$PR_ROUTER_FUNC"; do
  echo "=== $FUNC ==="
  aws lambda get-function-configuration \
    --function-name "$FUNC" --region "$REGION" \
    --query 'Environment.Variables' --output json | python3 -c "
import sys, json
d = json.load(sys.stdin)
for k in sorted(d.keys()):
    print(f'  {k}: [set]')
"
done

### Next step
`/auto-webhooks` — Configure ADO service hooks

Examples

1. /auto-lambda-env — Reads infra.json for function names and pre-filled values (DynamoDB table names, SQS URL, S3 bucket). Asks interactively for secrets (ADO PAT, Anthropic API key). Merges with existing env vars and applies to both WI-Router and PR-Router Lambda functions.

2. /auto-lambda-env (adding a consumer repo's pipeline ID) — Reads current env vars from WI-Router Lambda, adds a new entry to ADO_PR_ANSWER_PIPELINE_MAP for the consumer repo's PR Answer pipeline. Preserves all existing values and applies the merged configuration.

3. /auto-lambda-env (updating expired ADO PAT) — Asks for the new ADO PAT value. Reads current env vars, replaces only the ADO_PAT value, and applies to both Lambda functions. All other env vars remain unchanged.

Troubleshooting

• "update-function-configuration replaces ALL env vars" warning Cause: AWS Lambda's update API replaces the entire environment variable set, not individual values. Fix: The skill always reads current env vars first and merges changes. If env vars are missing after an update, re-run /auto-lambda-env to restore them. Check the audit log for what was applied.

• Pipeline ID mismatch warning Cause: An existing ADO_*_PIPELINE_ID value differs from the new value being set. Fix: Review the warning message — it shows old vs new values. If the pipeline was re-created, confirm the update. If the IDs should match, check /auto-pipelines output for the correct ID.

• Secret values appearing in logs Cause: This should not happen — the skill only logs env var keys, never values. Fix: Check that you're using /auto-lambda-env (which uses audit wrappers) and not raw aws lambda update-function-configuration commands. The audit log records the operation but not secret values.

Rules

• Always source audit.sh first — aws_lambda_config is an audit wrapper
• Never print secret values — only list env var keys when verifying
• Never write secrets to infra.json — only non-secret pre-filled values come from infra.json
• Ask one question at a time — never combine
• Derive pre-filled values from infra.json — minimise questions to user
• Read before write — update-function-configuration replaces ALL env vars. Always read current env vars first and merge changes
• Warn on pipeline ID overwrite — if an existing ADO_*_PIPELINE_ID differs from the new value, warn the user: "Pipeline ID will change from to . Proceed?" Skip if values match.
