For developers

Authoring

Write skills, and know when not to.

Authoring

1

  • Authoring

    Author an Agent Skill

    Write a SKILL.md an agent will actually load and follow — trigger-shaped description, valid frontmatter, progressive disclosure, no credentials.

Cost

4

  • Cost

    Read a Lobstack receipt

    Read the receipt Lobstack returns on every model call — cost_usd, savings_usd, baseline_reason — and report cost from it instead of estimating.

  • Cost

    Pick a model tier, not a flagship

    Choose the cheapest model tier that can actually do the task instead of defaulting to a flagship, and verify the choice before spending on it.

  • Cost

    Keep an agent inside a budget

    Hold an agent, job or run inside a hard dollar budget using the per-call cost the Gateway returns, and handle the 402 when an allowance runs out.

  • Cost

    Write a cost-aware system prompt

    Write or review a system prompt that does not quietly multiply the bill — bounded output, no re-sent bulk, tool schemas counted as the input tokens they are.

Gateway

1

  • Gateway

    Debug a Gateway 400, 402 or 429

    Diagnose a Lobstack Gateway failure from its status and error class and decide whether retrying can possibly help.

Migration

2

  • Migration

    Migrate an SDK call to the Gateway

    Move existing OpenAI or Anthropic SDK code onto the Lobstack Gateway by changing the base URL and the key, and verify it actually routed.

  • Migration

    Put Cursor or Aider behind the Gateway

    Route Cursor, Aider, Continue or any OpenAI-compatible tool through the Lobstack Gateway with a local proxy, and see a cost line per request.

Observability

2

  • Observability

    Audit a codebase for unmetered model calls

    Find model calls that bypass the gateway and therefore appear on no bill anyone reads, and detect the opposite fault of counting one call twice.

  • Observability

    Report spend from the usage API

    Answer what an organisation spent, on which models and keys, and what failed, from the Lobstack usage API rather than by estimating.
