tech-leadTurns a request into a dependency map and safe execution waves.Coordinate
Builds a constraint graph, separates decisions from tasks, and delegates only work with a testable return contract.

- Tools
- Read, Grep, Glob, Agent
- Model and access
- sonnet / read
interface-engineerDesigns every user state before touching the happy path.Build
Maps the interface as a state system, compresses choices, preserves established visual grammar, and tests keyboard and narrow-screen paths.

- Tools
- Read, Grep, Glob, Edit, Bash
- Model and access
- sonnet / write
backend-engineerBuilds APIs from invariants, failure contracts and retry behavior.Build
Defines what must remain true, then implements the smallest compatible service with explicit errors, idempotency and observability seams.

- Tools
- Read, Grep, Glob, Edit, Bash
- Model and access

data-engineerChanges durable data with a measured path back.Build
Scores irreversibility, profiles real access paths, and designs expand-contract migrations with validation and rollback evidence.

- Tools
- Read, Grep, Glob, Edit, Bash
- Model and access
- sonnet / write
test-engineerFinds the smallest tests that can disprove the change.Verify
Builds a behavioral topology, targets seams where failures hide, and rejects tests that only repeat the implementation.

- Tools
- Read, Grep, Glob, Edit, Bash
- Model and access
- haiku / write
security-reviewerBuilds evidence-backed attack paths across changed trust boundaries.Verify
Tracks attacker-controlled input to a protected effect, demands a complete exploit chain, and spends a strict false-positive budget.
- Source
- catalog/agents/security-reviewer.md
- Tools
- Read, Grep, Glob
- Model and access
- sonnet / read
performance-engineerUses controlled measurements to isolate the real bottleneck.Verify
Defines a user-visible budget, controls variance, tests one causal hypothesis at a time, and refuses benchmark theater.
- Source
- catalog/agents/performance-engineer.md
- Tools
- Read, Grep, Glob, Bash
- Model and access
- sonnet / execute
release-managerMakes the release decision from evidence and rollback readiness.Operate
Builds a blast-radius ledger, rehearses the abort path, and issues a clear ship, hold, or ship-with-guardrails decision.

- Tools
- Read, Grep, Glob, Bash
- Model and access

docs-engineerWrites docs as executable paths through real product states.Operate
Starts from the reader's current state, validates every command, and hunts contradictions between code, interface and documentation.

- Tools
- Read, Grep, Glob, Edit
- Model and access
- haiku / write
incident-investigatorRuns competing incident hypotheses without contaminating evidence.Operate
Maintains a living hypothesis board, seeks disconfirming evidence first, and converts uncertainty into the safest next diagnostic action.
