Persona Catalog
16 reviewer personas organized into always-on, cross-cutting conditional, and stack-specific conditional layers, plus CE-specific agents. The orchestrator uses this catalog to select which reviewers to spawn for each review.
Always-on (4 personas + 2 CE agents)
Spawned on every review regardless of diff content.
Persona agents (structured JSON output):
| Persona | Agent | Focus |
|---|---|---|
correctness |
compound-engineering:review:correctness-reviewer |
Logic errors, edge cases, state bugs, error propagation, intent compliance |
testing |
compound-engineering:review:testing-reviewer |
Coverage gaps, weak assertions, brittle tests, missing edge case tests |
maintainability |
compound-engineering:review:maintainability-reviewer |
Coupling, complexity, naming, dead code, premature abstraction |
project-standards |
compound-engineering:review:project-standards-reviewer |
CLAUDE.md and AGENTS.md compliance -- frontmatter, references, naming, cross-platform portability, tool selection |
CE agents (unstructured output, synthesized separately):
| Agent | Focus |
|---|---|
compound-engineering:review:agent-native-reviewer |
Verify new features are agent-accessible |
compound-engineering:research:learnings-researcher |
Search docs/solutions/ for past issues related to this PR's modules and patterns |
Conditional (7 personas)
Spawned when the orchestrator identifies relevant patterns in the diff. The orchestrator reads the full diff and reasons about selection -- this is agent judgment, not keyword matching.
| Persona | Agent | Select when diff touches... |
|---|---|---|
security |
compound-engineering:review:security-reviewer |
Auth middleware, public endpoints, user input handling, permission checks, secrets management |
performance |
compound-engineering:review:performance-reviewer |
Database queries, ORM calls, loop-heavy data transforms, caching layers, async/concurrent code |
api-contract |
compound-engineering:review:api-contract-reviewer |
Route definitions, serializer/interface changes, event schemas, exported type signatures, API versioning |
data-migrations |
compound-engineering:review:data-migrations-reviewer |
Migration files, schema changes, backfill scripts, data transformations |
reliability |
compound-engineering:review:reliability-reviewer |
Error handling, retry logic, circuit breakers, timeouts, background jobs, async handlers, health checks |
adversarial |
compound-engineering:review:adversarial-reviewer |
Diff has >=50 changed non-test, non-generated, non-lockfile lines, OR touches auth, payments, data mutations, external API integrations, or other high-risk domains |
previous-comments |
compound-engineering:review:previous-comments-reviewer |
Reviewing a PR that has existing review comments or review threads from prior review rounds |
Stack-Specific Conditional (5 personas)
These reviewers keep their original opinionated lens. They are additive with the cross-cutting personas above, not replacements for them.
| Persona | Agent | Select when diff touches... |
|---|---|---|
dhh-rails |
compound-engineering:review:dhh-rails-reviewer |
Rails architecture, service objects, authentication/session choices, Hotwire-vs-SPA boundaries, or abstractions that may fight Rails conventions |
kieran-rails |
compound-engineering:review:kieran-rails-reviewer |
Rails controllers, models, views, jobs, components, routes, or other application-layer Ruby code where clarity and conventions matter |
kieran-python |
compound-engineering:review:kieran-python-reviewer |
Python modules, endpoints, services, scripts, or typed domain code |
kieran-typescript |
compound-engineering:review:kieran-typescript-reviewer |
TypeScript components, services, hooks, utilities, or shared types |
julik-frontend-races |
compound-engineering:review:julik-frontend-races-reviewer |
Stimulus/Turbo controllers, DOM event wiring, timers, async UI flows, animations, or frontend state transitions with race potential |
CE Conditional Agents (migration-specific)
These CE-native agents provide specialized analysis beyond what the persona agents cover. Spawn them when the diff includes database migrations, schema.rb, or data backfills.
| Agent | Focus |
|---|---|
compound-engineering:review:schema-drift-detector |
Cross-references schema.rb changes against included migrations to catch unrelated drift |
compound-engineering:review:deployment-verification-agent |
Produces Go/No-Go deployment checklist with SQL verification queries and rollback procedures |
Selection rules
- Always spawn all 4 always-on personas plus the 2 CE always-on agents.
- For each cross-cutting conditional persona, the orchestrator reads the diff and decides whether the persona's domain is relevant. This is a judgment call, not a keyword match.
- For each stack-specific conditional persona, use file types and changed patterns as a starting point, then decide whether the diff actually introduces meaningful work for that reviewer. Do not spawn language-specific reviewers just because one config or generated file happens to match the extension.
- For CE conditional agents, spawn when the diff includes migration files (
db/migrate/*.rb,db/schema.rb) or data backfill scripts. - Announce the team before spawning with a one-line justification per conditional reviewer selected.
