Measured tools (7)

• list_skills

  List every opchain skill (id, displayName, description, phases, commands). Call this first to see the concept→ship pipeline.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• route

  Map a request or an /oc-* command to the skill that should handle it, with the entry phase. Use when you're unsure which skill fits.

  Parameters:

  • query (required) — string — An /oc-* command (e.g. /oc-discover) or a natural-language request (e.g. 'build me an app').

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_skill

  Return the full SKILL.md (the instructions) for one skill id. Load it, then follow it. Read get_orchestrator once before your first get_skill in a session.

  Parameters:

  • id (required) — string — Skill id, e.g. oc-app-architect.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_orchestrator

  Return the shared orchestrator protocol (welcome flow, pipeline map, active-chaining rules). Read once at the start of a session.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• create_checkpoint_session

  Create a private server-issued session for checkpoint storage. Retain the returned sessionId and use it with read_checkpoint/write_checkpoint; never invent or share one.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• read_checkpoint

  Read a skill's saved session checkpoint (where you left off). sessionId must be a private token returned by create_checkpoint_session.

  Parameters:

  • skill (required) — string
  • sessionId (required) — string — Private token returned by create_checkpoint_session.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• write_checkpoint

  Persist a skill's session checkpoint so progress survives across sessions. Stores the object as given (any JSON object up to 64 KiB); it does not validate it against the opchain checkpoint protocol, so write the shape the protocol documents.

  Parameters:

  • skill (required) — string
  • sessionId (required) — string — Private token returned by create_checkpoint_session.
  • checkpoint (required) — object — The checkpoint JSON to store (skill_state, next_actions, etc.).
  • expectedRevision — Local durable transport only: null creates only if absent; a revision updates only that revision. Omit for atomic unguarded replacement.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
