Core Concepts

Selector Cache

Local selector cache model, namespace partitioning, and cloud cache import behavior.

Selectors are stored under:

.opensteer/selectors/<namespace>

Each namespace contains:

  • index.json: selector registry metadata
  • <descriptor-id>.json: persisted descriptor records

Each descriptor stores:

  • action/extraction method
  • description
  • persisted DOM path (stable attributes + fallback hints)
  • metadata (createdAt, updatedAt, optional sourceUrl)

During replay, Opensteer resolves in this order:

  1. Persisted path by description
  2. Live DOM element counter
  3. Explicit CSS selector
  4. Built-in LLM resolution

When resolution succeeds through steps 2-4 and description is present, the resolved path is persisted for future runs.

Control API Contract

  • POST /v1/sessions
  • GET /v1/sessions/:sessionId
  • DELETE /v1/sessions/:sessionId
  • POST /v1/sessions/:sessionId/access
  • POST /selector-cache/import

POST /v1/sessions returns a semantic session descriptor: { sessionId, status, baseUrl }. Attach-only browser grants are issued later with POST /v1/sessions/:sessionId/access.
