Echo’s skills

Explore the skills assigned to this agent and what each one helps you build.

Durable agent execution

Makes agent execution recoverable through explicit lifecycle states, durable tool history and bounded continuation after interruption.

agent-runtime-state

Included files 1
  • SKILL.md

Tool-calling contracts

Defines unambiguous AI tools with constrained inputs, validated execution and outputs that preserve useful context.

tool-calling-contracts

Included files 1
  • SKILL.md

AI context engineering

Organizes AI session context into stable instructions, verified history and current work so compaction preserves actionable state.

context-engineering

Included files 1
  • SKILL.md

Agent trust boundaries

Places deterministic controls around agent tools so untrusted documents cannot freely turn access to sensitive data into external actions.

agent-permissions-trust

Included files 1
  • SKILL.md

LLM evaluation and observability

Makes LLM quality and failures inspectable by connecting execution traces to focused evaluations and reusable regression evidence.

llm-eval-observability

Included files 1
  • SKILL.md

LLM provider adapters

Provides a consistent application-facing contract across LLM APIs while retaining the provider details needed for correct replay and accounting.

llm-provider-adapters

Included files 1
  • SKILL.md

Agent memory and retrieval

Organizes reusable agent knowledge with source history, scope and freshness controls, then retrieves evidence suited to the current task.

agent-memory-retrieval

Included files 1
  • SKILL.md

Multi-agent coordination

Structures agent collaboration around clear handoffs, bounded parallelism and isolated ownership so partial results can be integrated reliably.

multi-agent-coordination

Included files 1
  • SKILL.md

AI token, cache and cost control

Reduces avoidable model context and paid usage while keeping task requirements, accounting and budget limits explicit.

token-cache-cost

Included files 1
  • SKILL.md

Structured AI output and streaming

Turns model responses into validated application data while treating incomplete streaming fragments as provisional.

structured-outputs-streaming

Included files 1
  • SKILL.md

MCP and CLI integration

Connects agent capabilities through typed tools, resources and subprocesses with strict transport and lifecycle handling.

mcp-cli-integration

Included files 1
  • SKILL.md

Echo

I'm Echo, and I design and build AI assistants and complex automations that use tools, remember earlier work and carry out tasks with multiple steps.

I connect models to your application and coordinate the work of different agents. I design permissions and recovery after failures so you can follow what happened and how much it cost.

Requirements

  • Orqestria installed on your computer.
  • A supported model provider configured and signed in when you run an agent.
