Sdlc Agents Setup Claude Code

Enable Claude Code on Amazon Bedrock in a GitHub repo

What this gives the user

Two capabilities, one workflow:

1. Issue coding — on @claude in an issue/comment, Claude Code clones the repo, reads the conversation, and opens a PR with an implementation.
2. PR code review — on a new PR or @claude review comment, Claude Code reviews the diff, leaves inline comments, and posts a summary.

Both use the same anthropics/claude-code-action@v1 GitHub Action, authenticated to Amazon Bedrock via GitHub Actions OIDC — no long-lived Anthropic API key, no Claude.ai auth, no CLAUDE_CODE_OAUTH_TOKEN. The action invokes us.anthropic.claude-opus-4-7-v1 through Bedrock InvokeModel.

Why Bedrock (vs API key)

• Single identity boundary: same AWS account that hosts the SDLC agent fleet already pays for and audits Claude usage.
• No secret rotation: OIDC tokens are short-lived and scoped to the repo.
• CloudTrail visibility: every InvokeModel call lands in CloudTrail, which matters for security reviews and cost attribution.

Use an Anthropic API key instead only if the user has a constraint that forces it (e.g. no AWS account, or a different region story than their fleet).

Prerequisites

• A GitHub repo the user admins.
• AWS account with Bedrock model access enabled for us.anthropic.claude-opus-4-7-v1 in the region Claude Code will run in (default us-east-1). The region is independent of where the SDLC agent fleet runs — Claude Code only needs bedrock:InvokeModel from CI runners.
• gh CLI authenticated as a repo admin (for setting secrets/variables); or the user can click through the UI.
• If using the SDLC Agent Fleet: sdlc-agents-provision-aws Step 0 already created a deploy role (default name sdlc-agents-deploy). You can either reuse it (simplest) or create a dedicated ClaudeCodeBedrockRole (cleaner blast radius). This skill does the dedicated-role path — reuse is a footnote at the end.

Collect values up front

Ask the user and record:

• AWS_ACCOUNT_ID — 12 digits
• AWS_REGION — the region Claude Code will call Bedrock in (default us-east-1; must have Opus 4.7 model access)
• GITHUB_ORG and GITHUB_REPO — scopes the OIDC trust policy
• Which events should trigger Claude (defaults below are sensible):
  • @claude in issue or issue comment → code against issue and open PR
  • @claude in PR review comment → respond to the review
  • PR opened/synchronize → auto-review every PR (opt-in; noisy on busy repos)

Step 1 — Verify Bedrock model access

aws bedrock get-foundation-model \
  --model-identifier us.anthropic.claude-opus-4-7-v1 \
  --region "$AWS_REGION"

If this returns ResourceNotFoundException, stop and tell the user to request access in the Bedrock console (Model access → Opus 4.7) before continuing. Provisioning IAM/OIDC without model access will succeed but the first @claude run will 403.

Step 2 — Create the IAM role for Claude Code

The role needs two permissions: bedrock:InvokeModel on the target model (and the cross-region inference profile if using one), and the trust policy to be assumed by GitHub Actions OIDC from the specific repo.

2a. Ensure the GitHub OIDC provider exists in the account

aws iam list-open-id-connect-providers \
  | grep -q 'token.actions.githubusercontent.com' \
  || aws iam create-open-id-connect-provider \
       --url https://token.actions.githubusercontent.com \
       --client-id-list sts.amazonaws.com \
       --thumbprint-list 6938fd4d98bab03faadb97b34396831e3780aea1

(Idempotent — skip if already present. sdlc-agents-provision-aws Step 0a creates one for the fleet; reuse it.)

2b. Create the role with a scoped trust policy

cat > /tmp/trust.json <<EOF
{
  "Version": "2012-10-17",
  "Statement": [{
    "Effect": "Allow",
    "Principal": {
      "Federated": "arn:aws:iam::${AWS_ACCOUNT_ID}:oidc-provider/token.actions.githubusercontent.com"
    },
    "Action": "sts:AssumeRoleWithWebIdentity",
    "Condition": {
      "StringEquals": {
        "token.actions.githubusercontent.com:aud": "sts.amazonaws.com",
        "token.actions.githubusercontent.com:sub": [
          "repo:${GITHUB_ORG}/${GITHUB_REPO}:ref:refs/heads/main",
          "repo:${GITHUB_ORG}/${GITHUB_REPO}:pull_request"
        ]
      }
    }
  }]
}
EOF

aws iam create-role \
  --role-name ClaudeCodeBedrockRole \
  --assume-role-policy-document file:///tmp/trust.json \
  --description "Invoked by GitHub Actions in ${GITHUB_ORG}/${GITHUB_REPO} to call Bedrock for Claude Code" \
  || echo "(role exists — update trust policy if org/repo changed)"

rm /tmp/trust.json

Why two explicit subjects and not :*: StringLike: repo:<org>/<repo>:* allows any branch, tag, or environment in the repo to assume the role — including feature branches that haven't been reviewed. The claude-code.yml workflow needs exactly two subjects: pull_request (only emitted for the pull_request: [opened, synchronize] trigger, the sole "pull request event" in OIDC terms) and ref:refs/heads/main (the default-branch sub — emitted for issue_comment, pull_request_review, and pull_request_review_comment, all of which run in the default-branch context). Enumerating them with StringEquals is the default here. If you share the role across multiple repos, extend the list — one entry per <org>/<repo> per subject — rather than falling back to StringLike with wildcards.

2c. Attach the Bedrock permission

cat > /tmp/bedrock-invoke.json <<EOF
{
  "Version": "2012-10-17",
  "Statement": [{
    "Effect": "Allow",
    "Action": [
      "bedrock:InvokeModel",
      "bedrock:InvokeModelWithResponseStream"
    ],
    "Resource": [
      "arn:aws:bedrock:${AWS_REGION}::foundation-model/anthropic.claude-opus-4-7-v1:0",
      "arn:aws:bedrock:*::foundation-model/anthropic.claude-opus-4-7-v1:0",
      "arn:aws:bedrock:${AWS_REGION}:${AWS_ACCOUNT_ID}:inference-profile/us.anthropic.claude-opus-4-7-v1"
    ]
  }]
}
EOF

aws iam put-role-policy \
  --role-name ClaudeCodeBedrockRole \
  --policy-name BedrockInvokeOpus47 \
  --policy-document file:///tmp/bedrock-invoke.json

rm /tmp/bedrock-invoke.json

Opus 4.7 is served through a cross-region inference profile (us.* prefix) — both the profile ARN and the underlying foundation-model ARN (in any region the profile routes to) must be allowed. The wildcard region on the foundation-model ARN covers that without enumerating each region the profile might land on.

Capture the role ARN:

ROLE_ARN=$(aws iam get-role --role-name ClaudeCodeBedrockRole --query 'Role.Arn' --output text)
echo "$ROLE_ARN"

Step 3 — Install the workflow in the user's repo

Drop this file at .github/workflows/claude-code.yml in the target repo:

name: Claude Code Assistant

on:
  issue_comment:
    types: [created]
  pull_request_review_comment:
    types: [created]
  pull_request_review:
    types: [submitted]
  pull_request:
    types: [opened, synchronize]
  issues:
    types: [opened, assigned, labeled]

jobs:
  claude-response:
    # Respond on:
    #   - any PR open/sync (auto-review — remove this line to make review explicit-only)
    #   - @claude in an issue, issue comment, or PR review comment
    if: |
      github.event_name == 'pull_request' ||
      (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
      pull-requests: write
      issues: write
      id-token: write
      actions: read
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 1

      - name: Configure AWS Credentials (OIDC)
        uses: aws-actions/configure-aws-credentials@v4
        with:
          role-to-assume: ${{ secrets.CLAUDE_CODE_ROLE_ARN }}
          aws-region: ${{ vars.CLAUDE_CODE_AWS_REGION || 'us-east-1' }}

      - uses: anthropics/claude-code-action@v1
        with:
          use_bedrock: "true"
          claude_args: |
            --model us.anthropic.claude-opus-4-7-v1

Two knobs to tune before the user commits:

1. Auto-review on every PR vs explicit @claude review. The pull_request trigger above runs on every push to every PR. On active repos this gets noisy and spendy. To make review explicit:

   • Remove github.event_name == 'pull_request' || from the if: condition.
   • Remove the pull_request entry from on:.

   Now @claude review in a PR comment triggers it; nothing auto-runs.

2. Issue coding gate. The condition above triggers on any issue body containing @claude. Narrower options:

   • issues.types: [labeled] only + check contains(github.event.label.name, 'claude') — only run when someone labels the issue claude.
   • Keep mention-based but ignore bot mentions: add && github.event.sender.type != 'Bot'.

Commit the file on a branch, push, open a PR. (Don't push straight to main — Claude Code won't be triggerable to review itself yet.)

Step 4 — Wire up the secrets and variables

In the target repo — Settings → Secrets and variables → Actions:

Via gh:

gh secret   set CLAUDE_CODE_ROLE_ARN      --body "$ROLE_ARN"
gh variable set CLAUDE_CODE_AWS_REGION    --body "$AWS_REGION"

The role ARN is a secret because it identifies a specific role in a specific account that someone could target for misconfiguration probes. The region is a variable because there's no sensitivity to it — it just shapes which endpoint the action hits.

Step 5 — Verify

Three checks, in order. Don't skip — each catches a different class of failure.

5a. IAM simulation (offline, fast)

aws iam simulate-principal-policy \
  --policy-source-arn "$ROLE_ARN" \
  --action-names bedrock:InvokeModel \
  --resource-arns "arn:aws:bedrock:${AWS_REGION}:${AWS_ACCOUNT_ID}:inference-profile/us.anthropic.claude-opus-4-7-v1" \
  --query 'EvaluationResults[0].EvalDecision' --output text

Must print allowed. If it prints implicitDeny or explicitDeny, re-check the role policy (Step 2c).

5b. CI reaches Bedrock (live, but cheap)

On the branch where you added claude-code.yml, open a PR with a trivial change. The workflow should:

1. Start within ~10s of PR open
2. Successfully run the "Configure AWS Credentials (OIDC)" step
3. Proceed to the claude-code-action step

Inspect the run:

gh run list --workflow "Claude Code Assistant" --limit 1
gh run view <run-id> --log

Expected failures to debug:

5c. End-to-end user test

Ask the user to post @claude hello, can you see this? as a comment on any issue in the repo. Within ~30s Claude Code should post a reply. If silent after 90s:

• gh run list — was a workflow triggered at all?
• If yes: check the log for which step failed.
• If no: the if: condition excluded this event. Usually missing @claude substring or a PR vs issue mismatch.

Reusing the existing deploy role (footnote)

If the user already has sdlc-agents-deploy from sdlc-agents-provision-aws Step 0, they can attach the Bedrock inline policy from Step 2c to that role and set CLAUDE_CODE_ROLE_ARN to the existing AWS_DEPLOY_ROLE_ARN. One fewer role to manage, at the cost of a broader blast radius: if @claude gets compromised (via prompt injection that extracts secrets), an attacker has deploy privileges. For production, keep the roles separate.

What this skill does NOT do

• Configure Claude Code outside GitHub Actions (IDE, local CLI, or desktop app) — that path uses the user's personal Claude account, not Bedrock.
• Install Claude Code Action v0.x — the @v1 path is stable and the only supported Bedrock integration as of this writing.
• Handle non-Anthropic models via Bedrock — the action expects anthropic.* model IDs.
• Filter or redact repo contents before they go to Bedrock. Bedrock's Anthropic models do not train on customer data, but if the repo has regulated content (PHI, export-controlled code) the user needs a separate review before enabling @claude at all. Flag this; don't paper over it.
