Curated library of 41 public AI agent skills for Ruby on Rails development. Organized by category: planning, testing, code-quality, ddd, engines, infrastructure, api, patterns, context, and orchestration. Covers code review, architecture, security, testing (RSpec), engines, service objects, DDD patterns, and TDD automation. Repository workflows remain documented in GitHub but are intentionally excluded from the Tessl tile.

Normalize inputs, classify each work item, apply title conventions, draft tickets in a standard structure, then either return markdown drafts or create issues in the issue tracker after explicit approval.
Plan input -> classify each item -> draft tickets -> confirm before tracker creation
Default mode: draft-only, unless the user explicitly asks to create issues.
Ticket shape: Title, Type, Area, Bucket, Summary, Background, Acceptance Criteria, Dependencies, Technical Notes.Do not create tracker issues unless the user explicitly asks for creation.
Do not assume tracker credentials, project fields, sprint IDs, status behavior, or required custom fields.
If the user only asks for tickets, return markdown drafts.Extract planning inputs:
If the user already has a plan, do not re-plan unless there is a material gap.
Assign these core planning attributes to each ticket:
| Attribute | Values |
|---|---|
type | Story | Task |
area | backend | web | mobile | cross-platform | external |
execution_order | foundation | api | client | follow-up |
dependency_level | unblocked | blocked |
target_bucket | ready-to-refine | next-dev-sprint | later |
Additional attributes to apply when relevant: coordination_need (single-team | multi-team), external_dependency (yes | no), urgency (normal | priority).
Backend/API enablers generally come before dependent web/mobile tickets.
Defaults unless the user overrides:
foundation and api tickets → placed before all dependent client ticketsclient tickets → blocked until the API surface they depend on is stableexternal confirmation tickets → excluded from active build sprintsfollow-up tickets → ready-to-refine or later until their enabling work is completeUse these prefixes:
BE | for backendFE | for web / frontendMobile | for mobileWhen writing the ticket title, leave a space after the |. Do not add those prefixes to tickets that are not owned by those areas unless the user explicitly wants that.
Use this section order:
| Section | Job |
|---|---|
| Summary | State the outcome |
| Background | Explain why |
| Acceptance Criteria | List observable criteria |
| Dependencies | Note blockers |
| Technical Notes | Implementation details that affect sequencing or scoping only |
Keep the main sections business-facing.
Draft-only:
Create in issue tracker:
Example field shape for MCP/API creation:
{
"project": "<project-key>",
"issuetype": "Story",
"summary": "BE | Enable payment webhook processing",
"description": "<full ticket body>",
"labels": ["payments", "backend"],
"components": ["payments-service"],
"sprint": { "id": "<sprint-id>" },
"epic": "<epic-key>"
}Load these files only when their specific content is needed:
When asked to draft tickets, your output MUST include:
BE |, FE |, or Mobile | only when the ticket is owned by that area.type, area, execution_order, dependency_level, and target_bucket for every ticket.Summary, Background, Acceptance Criteria, Dependencies, and Technical Notes, in that order.| Skill | When to chain |
|---|---|
| generate-tasks | After tasks exist or in parallel — same initiative can feed ticket breakdown |
| create-prd | When tickets should align with PRD scope and acceptance themes |
