Managing AWS Codecommit

AWS CodeCommit Management Skill

Analyze and manage AWS CodeCommit repositories, branches, and pull requests.

MANDATORY: Discovery-First Pattern

Always list repositories before querying specific resources.

Phase 1: Discovery

#!/bin/bash
export AWS_PAGER=""

echo "=== CodeCommit Repositories ==="
aws codecommit list-repositories --output text \
  --query 'repositories[].[repositoryName,repositoryId]'

echo ""
echo "=== Repository Details ==="
for repo in $(aws codecommit list-repositories --output text --query 'repositories[].repositoryName'); do
  aws codecommit get-repository --repository-name "$repo" --output text \
    --query 'repositoryMetadata.[repositoryName,defaultBranch,cloneUrlHttp,lastModifiedDate]' &
done
wait

echo ""
echo "=== Branches Per Repository ==="
for repo in $(aws codecommit list-repositories --output text --query 'repositories[].repositoryName'); do
  {
    branches=$(aws codecommit list-branches --repository-name "$repo" --output text --query 'branches[]' | wc -w)
    printf "%s\t%s branches\n" "$repo" "$branches"
  } &
done
wait

Phase 2: Analysis

#!/bin/bash
export AWS_PAGER=""

echo "=== Open Pull Requests ==="
for repo in $(aws codecommit list-repositories --output text --query 'repositories[].repositoryName'); do
  for pr_id in $(aws codecommit list-pull-requests --repository-name "$repo" --pull-request-status OPEN --output text --query 'pullRequestIds[]' 2>/dev/null); do
    aws codecommit get-pull-request --pull-request-id "$pr_id" --output text \
      --query "pullRequest.[pullRequestId,title,authorArn,pullRequestStatus,creationDate]" &
  done
done
wait | head -20

echo ""
echo "=== Recent Commits (default branch) ==="
for repo in $(aws codecommit list-repositories --output text --query 'repositories[].repositoryName'); do
  {
    branch=$(aws codecommit get-repository --repository-name "$repo" --output text --query 'repositoryMetadata.defaultBranch')
    if [ -n "$branch" ] && [ "$branch" != "None" ]; then
      aws codecommit get-branch --repository-name "$repo" --branch-name "$branch" --output text \
        --query "branch.[\"$repo\",branchName,commitId]" 2>/dev/null
    fi
  } &
done
wait

echo ""
echo "=== Approval Rule Templates ==="
aws codecommit list-approval-rule-templates --output text \
  --query 'approvalRuleTemplateNames[]' 2>/dev/null

echo ""
echo "=== Repository Triggers ==="
for repo in $(aws codecommit list-repositories --output text --query 'repositories[].repositoryName'); do
  aws codecommit get-repository-triggers --repository-name "$repo" --output text \
    --query "triggers[].[\"$repo\",name,destinationArn]" 2>/dev/null &
done
wait

Output Format

• Target ≤50 lines per output
• Use --output text --query for all commands
• Tab-delimited fields: RepoName, Branch, PRId, Status
• Limit commit history to last 5 per repository
• Never dump full diffs -- show commit metadata only

Anti-Hallucination Rules

1. NEVER assume resource names — always discover via CLI/API in Phase 1 before referencing in Phase 2.
2. NEVER fabricate metric names or dimensions — verify against the service documentation or --help output.
3. NEVER mix CLI commands between service versions — confirm which version/API you are targeting.
4. ALWAYS use the discovery → verify → analyze chain — every resource referenced must have been discovered first.
5. ALWAYS handle empty results gracefully — an empty response is valid data, not an error to retry.

Counter-Rationalizations

Common Pitfalls

• Default branch: Not all repos have a default branch set -- check for None/empty before querying
• Pull request IDs: List returns IDs only -- need separate get-pull-request call for details
• Approval rules: Templates must be associated with repos to take effect -- check associations
• Triggers: Support SNS and Lambda destinations -- verify destination ARN is valid
• Repository size: No direct API for repo size -- use get-repository metadata for last modified date
• CodeCommit deprecation: AWS has announced CodeCommit is no longer accepting new customers -- consider migration paths
