# Spacefast references

The router and the load-bearing publish and edit paths live in `SKILL.md`. This file holds what an
agent loads only when the task needs it. Nothing here overrides the safety rules in `SKILL.md`.

## Connectors

A connector is a tool source registered for the team: an OpenAPI spec, a GraphQL endpoint, or a remote MCP server. A connection is one authenticated account on it. `search()` with no arguments lists the connectors, how many connections each has, and a few representative tools. `search({ connector })` lists one connector's tools; `search({ query })` searches tool names and summaries across everything you can reach. Every listed tool carries an `address`, its `safety`, and the `effect` policy resolved for it: `approve`, `require_approval`, or `block`.

Call the connector namespace inside one `execute` program, for example `tools.linear.mutation.issueCreate({ input: { teamId, title } })` on a Linear GraphQL connector. Use `tools.search` and `tools.describe.tool` in the program to find names and argument types. Calls use the caller's grants and connection policy; credentials stay outside the program. A bare connector slug requires exactly one usable connection; with several accounts use `tools.<connector>.<connectionId>.<tool>(args)` with the connection id from search, or the run returns `connection_ambiguous`.

A call that resolves to `require_approval` parks the run: `execute` returns `awaiting_approval` with a `runId` prefixed `cxr_` and an `approvalUrl`. Continue it with `resume_execution` under the approval rules. A parked run survives the request that created it but expires; when it does, submit the work again. Never send `accept` for a user who has not seen the action.

Do not ask for a credential; no endpoint returns one. If nothing is connected, tell the user to connect it in the dashboard. Do not retry a `block` against another address.

## Source editing

CodeStorage stores base, staged, and working snapshots on protected workspace refs. Postgres stores
coordination metadata. Agents manage this state; the Apps only display it. The workflow itself is in
`SKILL.md`; these are the paths around it.

- On branch movement, call the workspace sync operation. It replays staging first, then working
  changes. If conflicts remain, read the supplied conflict labels. Resolve with complete contents,
  explicit deletion, or a verified pinned side. Read the result; another phase can have more
  conflicts.
- Restore operations replace selected working files from staging or a saved commit. Preparing an
  undo applies the inverse of a non-merge commit to working files. Neither changes staging, commits,
  deploys, or rewrites saved history. Never send a display patch as an input patch.
- Connected repositories are read-only. Use their upstream workflow for writes.
- History follows first parents; keep the returned source commit pinned across pages. Use Source
  comparison for saved Git source and Deployment comparison for served artifacts. Deployment
  contents require `versions:download`, not publishing access.
- Present the compact cards instead of repeating whole trees, patches, or logs. Do not expose
  staging or internal refs in a card. Do not invent a form, approval gate, or prompt that asks the
  user to trigger a write; the Apps already carry the writes they allow.

## Plan-gated behavior

Do not guess whether a team is on a free or paid plan. Publish the intended artifact, then read
and report the API or runtime diagnostics. When a feature is plan-gated, say exactly what the
diagnostic says, in this wording: "Not available on Free. Available on Go and Plus."
For large files, report the blocked paths and size diagnostics; do not rewrite or delete user
files unless asked. Proxy rules are not plan-gated: an unclaimed Space reaches only the trusted
hosts, and claiming opens the rest.

## Product rules

- `space` is the main object; `publish` is the canonical action. Deploying is publishing: a
  deployment is a version, and the canonical nouns are version, channel, and build.
- `version` is an immutable snapshot. `domain` is user-facing; avoid `hostname` except for DNS
  diagnostics.
- `API key`, `space key`, and `claim link` have distinct meanings.
- New Spaces are private until explicit Grants widen access.
