Build and ship

The build capabilities at a glance. Engineering playbooks, worktrees, pull-request review, API collections, deploy checks, plan specs, releases.

The capabilities Kevin brings to code, grouped in one table. How they fit together (the loop, the playbooks, the principles, review, and releases) is in Engineering. Run a skill as /agent-kevin:<name> in Claude Code or $<name> in Codex.

CapabilityWhat it doesSkills and tools
WorktreesParallel agents on one repo: sibling worktrees created, bootstrapped with your local config, and torn down.setup-worktree
tools: setup_worktree, list_worktrees, remove_worktree
Pull requestsAn adversarial review of a teammate’s PR across correctness, security, regressions, and tests, verified against the code and the local build, with comments ready to paste at file and line; reply mode judges every thread on your own PR. The review on your own PR gets answered and a walkthrough preps you to present it. Once it lands, a deploy health check verifies the rollout.engineer
tools: github_pr_view, github_pr_diff, github_pr_checks, github_pr_comments, github_run_log
API collectionsRequests drafted as Bruno or Postman collections, or plain curl, that you fire from your own client.api-collections
tools: curl_run
Deploy health check
with a deployment
Post-deploy verification anchored on the commit, with a canary traced through the changed code, or a standing sweep across the whole system. Pass, warn, or fail per check, read-only, saved as a report.health-check
Plan specsAn intent turned into a spec and a plan before any code is written, with a design section for code: the caller’s usage first, a rejected alternative, and a check on every task.plan-spec
EngineeringCode work run as a playbook: reproduce and root-cause a bug, build a feature from a named data shape, refactor against pinned behavior, measure a slowdown, or settle a design with a throwaway prototype. Twenty-three named engineering principles back every step, proof is the running artifact rather than a green build, and a comment pass runs before you see the diff.engineer
Flow audits
with a deployment
A critical flow (onboarding, identity verification, a rate-limited endpoint) audited end to end against its spec and its live data, with findings and fix prompts.health-check kyc-flow health-check rate-endpoint
Tests, from the session
with a deployment
The repo’s own test commands discovered and run from inside the session, results read back.tools: testing_commands, testing_run
GitHub, from the sessionIssues, pull-request lists, workflow runs, and fast-forwards without leaving the terminal.tools: github_issue_list, github_issue_view, github_pr_list, github_run_list, github_fast_forward
Release and upgradeVersioned releases with an upgrade contract; a home reconciled after every update.release upgrade
tools: run_upgrade
