fusion-plugin-linear-import is a bundled Fusion integration plugin that imports Linear issues into Fusion tasks. It is intentionally implemented through plugin settings, plugin routes, plugin tools, and a plugin dashboard view — not through core Linear settings or host-owned /api/linear/* routes.

Setup

Install or enable Linear Import from Settings → Plugins / Plugin Manager.
Open the plugin settings and enter a Linear personal API key.
Optionally set a default team key/ID, issue state filter, and assignee ID.
Open the Linear Import plugin dashboard view to browse and import issues.

The API key is a plugin password setting. Fusion uses it only for HTTPS GraphQL requests to Linear and does not include it in route responses, tool results, task descriptions, task documents, or logs.

Supported filters

The dashboard view, routes, and tools share the same filters:

query — matches issue title, description, or identifier.
teamKey / teamId — Linear team key or UUID.
state — active, backlog, started, unstarted, completed, canceled, or all.
assigneeId — Linear user UUID.
limit — bounded to 1–100 issues.
after — optional Linear pagination cursor for browse calls.

Routes

All routes are plugin-scoped under /api/plugins/fusion-plugin-linear-import/*:

GET /status — checks whether the plugin has a usable API key.
POST /issues — lists/searches issues.
POST /issues/detail — fetches one issue by UUID or identifier.
POST /issues/import — imports one issue into triage.
POST /issues/import-batch — imports up to 25 selected issues.

Dashboard requests include projectId when the host provides one so the plugin uses the project-scoped plugin settings and task store.

Agent tools

The plugin registers plugin tools (not built-in fn_* tools):

linear_import_browse_issues
linear_import_issue
linear_import_issues

Tool results summarize imported/skipped issues and include safe issue/task details only.

Import behavior and duplicate handling

Imported tasks are created in triage. The task description contains the Linear issue body or (no description), followed by Source: <Linear URL>, the Linear identifier, team, and state. Task provenance stores:

sourceIssue.provider: "linear"
stable Linear issue id as sourceIssue.externalIssueId
source URL
source.sourceType: "api"
source.sourceMetadata.provider: "linear"
Linear issue id, identifier, URL, team, state, assignee, and timestamps where available

Duplicate detection checks non-archived tasks by Linear issue id, Linear identifier, and source URL before creating a task. Duplicate route/tool responses identify the existing Fusion task id when available.

Limitations and non-goals

No Linear CLI or binary dependency is required or installed.
No host-owned /api/linear/* routes or core Linear settings are added.
Imports are read-only with respect to Linear; the plugin does not comment on, close, reopen, or update Linear issues.
Linear workspace/team permissions are determined by the configured API key.
