Linear API Proxy

When to Use

• Need to make custom Linear GraphQL queries not covered by specific skills
• Direct API access required for advanced operations

Usage

CUR="$PWD"
while [ "$CUR" != "/" ] && [ ! -d "$CUR/.agents/skills" ]; do CUR=$(dirname "$CUR"); done
source "$CUR/.agents/skills/_lib/sb_api_call.sh"

sb_api_call POST /api/linear \
  -H "Content-Type: application/json" \
  -d '{
    "query": "query { issues(first: 10) { nodes { id title } } }"
  }'

Parameters

• query: GraphQL query string (required)
• variables: Optional GraphQL variables object

Response

JSON response from Linear API or error object with error field.

Post a Comment (use this for replies / questions / triage verdicts)

Always post comments through the dedicated /comment route — NOT a raw commentCreate GraphQL call. The host adds the hidden <!-- switchboard --> self-marker so the inbound poll skips your own comment and you don't trigger a feedback loop. The token stays host-side.

sb_api_call POST /comment \
  -H "Content-Type: application/json" \
  -d '{
    "provider": "linear",
    "id": "<Linear Issue ID UUID from the plan metadata>",
    "body": "Your comment text here."
  }'

• provider: "linear"
• id: the issue UUID (the **Linear Issue ID:** line in the plan file), NOT the ENG-123 identifier
• body: the comment markdown. Do not add any marker yourself — the host stamps it.
