Use when defining who the actors in a service are — segments, JTBD forces, context, constraints, and relationships between actors
From service-designnpx claudepluginhub zemptime/zemptime-marketplace --plugin service-designThis skill uses the workspace's default tool permissions.
Enables AI agents to execute x402 payments with per-task budgets, spending controls, and non-custodial wallets via MCP tools. Use when agents pay for APIs, services, or other agents.
Designs and optimizes AI agent action spaces, tool definitions, observation formats, error recovery, and context for higher task completion rates.
Compares coding agents like Claude Code and Aider on custom YAML-defined codebase tasks using git worktrees, measuring pass rate, cost, time, and consistency.
Core principle: Every artifact references actors. If actors aren't defined, every artifact invents its own definition. Actor profiles are the shared foundation — run this skill before all others.
Map four forces per actor. These explain why someone adopts or abandons a service, distinct from what they experience once using it:
| Force | Question |
|---|---|
| Push | What's broken about their current solution? |
| Pull | What about this service looks better? |
| Anxiety | What makes them hesitate? |
| Habit | What keeps them doing it the old way? |
Extend to functional, social, and emotional goals. Task completion alone misses half the switching calculus.
Environment, stakes, frequency, constraints. A user on a phone in a noisy shop with 30 seconds is not the same actor as one at a desk with an hour. Make these explicit.
Customer ↔ frontline staff ↔ back-office ↔ external partners. Map who serves whom, who depends on whom, who sets terms. One actor's constraint is often another's backstage action.
Code reveals what the system assumes about users — roles, permissions, workflows. Transcripts reveal what they actually think and struggle with. Business docs reveal intended segments. Accept all three; triangulate. Never invent quotes or emotions.
One profile per actor type. Multiple actors = multiple files in the same slice.
Tag every claim: [confirmed] (verified in code, analytics, or direct quote), [hypothesis] (inferred from patterns), or [gap] (unknown). Segments from analytics = [confirmed]. Inferred motivations = [hypothesis]. For each hypothesis, note what would confirm.
Write to docs/service-design/<slice>/actor-profile-<name>.md using the template at service-design/templates/actor-profile.md. One file per actor type.
service-design:empathy-analysis deepens the emotional layer for a single actor this profile defines. service-design:service-blueprint maps the service structure actors move through. service-design:journey-map sequences their experience across time.
