CAST Agent Registry

The full CAST agent roster with model tier and one-line role description. The plugin installs a curated subset — run cast status or cast doctor for the live installed count.

Agent	Model	Role
api-contract	haiku 4.5	API contract guardian — detects breaking changes in REST endpoints, compares route signatures and response shapes, generates contract tests
backend-writer	sonnet	Implementation specialist for backend feature work, bug fixes, and planned changes — receives tasks from planner or orchestrator and owns the full write-test-review cycle
bash-specialist	sonnet	Shell scripting specialist for CAST hook scripts, BATS tests, and automation scripts — use for new hook scripts, BATS test authoring, and shell refactors
code-reviewer	haiku 4.5	Per-unit code-quality and security review of a single logical change mid-flight, any language — dispatched after every writer or debugger unit, before commit
commit	haiku 4.5	Git commit specialist — reads staged changes, writes a semantic commit message, and creates the commit following CAST conventions
db-reader	sonnet	Read-only data-analysis specialist — SQL queries, data exploration, and reporting against BigQuery or SQLite
debugger	sonnet	Root-cause debugging of concrete failures — a reproduced error, a stack trace, a failing test, or observably wrong runtime behavior
dep-auditor	haiku 4.5	Dependency auditor — reviews package changes for transitive risk, known CVEs, version compatibility, and license concerns
devops	haiku 4.5	CI/CD pipeline management and GitHub Actions workflow authoring
docs	haiku 4.5	Documentation specialist — handles README audits/rewrites and doc updates after code changes
email-drafter	haiku 4.5	Email and portfolio-sync specialist — drafts Gmail messages (compose, reply) for review, never sends, and syncs showcase repo READMEs with actual project state
eval-writer	sonnet	Eval and benchmark fixture author for Claude API and CAST agent prompts — generates YAML eval cases with runnable graders that catch prompt-level behavior drift
frontend-qa	haiku 4.5	Deep React 19 and TypeScript review of .tsx/.ts files — prop typing, TanStack Query hook usage, frontend-to-backend API-contract alignment, Vitest coverage gaps, and a11y basics
frontend-writer	sonnet	Implementation specialist for frontend feature work, bug fixes, and planned changes — receives tasks from planner or orchestrator and owns the full write-test-review cycle
infra-writer	haiku 4.5	Docker/containerization, infrastructure-as-code (Terraform, CloudFormation stubs), deployment configuration, and environment management
merge	haiku 4.5	PR lifecycle agent — watches CI checks on the current PR and stops for confirmation before squash-merging after approval
migration-reviewer	opus	Database schema change reviewer — analyzes migration files for safety, generates rollback plans, validates ordering, and checks for destructive operations
morning-briefing	haiku 4.5	Daily briefing agent that gathers git activity, action items, and CAST system intelligence, then assembles a structured morning report
planner	sonnet	Planning specialist that converts feature requests into specs and ordered task breakdowns — reserve for genuinely multi-file/multi-agent work requiring an Agent Dispatch Manifest
pr-reviewer	sonnet	Whole-PR review at PR-open time — reads the full multi-commit diff, commit-message coherence, scope creep, coverage gaps, and breaking-change surface
push	haiku 4.5	Git push specialist — verifies branch safety, shows unpushed commits, sets upstream if needed, then pushes using the CAST workflow
release-notes	haiku 4.5	Release notes generator — creates structured changelogs from git commits, resolved issues, and breaking changes between tags
report-writer	haiku 4.5	Status/chain-reporting specialist — generates weekly status updates, project health checks, and multi-agent chain execution summaries
researcher	sonnet	Multi-purpose research and analysis specialist for codebase exploration, web research, technology comparisons, and architectural recommendations
security	sonnet	Security review specialist for code handling user input, auth, API keys, database queries, or external data — flags injection risks, secrets exposure, and authorization gaps
test-runner	haiku 4.5	Test execution gate — runs the project test suite and gates the chain on real exit codes; MUST run in its own sequential batch, never co-scheduled with review agents
test-writer	haiku 4.5	Test design specialist — writes test suites for existing code covering happy path, edge cases, and error states; detects the test framework in use and follows its conventions
