Optimize this skill with Tessl
npx tessl skill review --optimize ./.codex/skills/linear/SKILL.mdUse this skill for raw Linear GraphQL work during Symphony app-server sessions.
Use the linear_graphql client tool exposed by Symphony's app-server session.
It reuses Symphony's configured Linear auth for the session.
Tool input:
{
"query": "query or mutation document",
"variables": {
"optional": "graphql variables object"
}
}Tool behavior:
errors array as a failed GraphQL operation even if the
tool call itself completed.When you need an unfamiliar mutation, input type, or object field, use targeted
introspection through linear_graphql.
List mutation names:
query ListMutations {
__type(name: "Mutation") {
fields {
name
}
}
}Inspect a specific input object:
query CommentCreateInputShape {
__type(name: "CommentCreateInput") {
inputFields {
name
type {
kind
name
ofType {
kind
name
}
}
}
}
}Use these progressively:
issue(id: $key) when you have a ticket key such as MT-686.issues(filter: ...) when you need identifier search semantics.issue(id: $id) for narrower reads.Lookup by issue key:
query IssueByKey($key: String!) {
issue(id: $key) {
id
identifier
title
state {
id
name
type
}
project {
id
name
}
branchName
url
description
updatedAt
links {
nodes {
id
url
title
}
}
}
}Lookup by identifier filter:
query IssueByIdentifier($identifier: String!) {
issues(filter: { identifier: { eq: $identifier } }, first: 1) {
nodes {
id
identifier
title
state {
id
name
type
}
project {
id
name
}
branchName
url
description
updatedAt
}
}
}Resolve a key to an internal id:
query IssueByIdOrKey($id: String!) {
issue(id: $id) {
id
identifier
title
}
}Read the issue once the internal id is known:
query IssueDetails($id: String!) {
issue(id: $id) {
id
identifier
title
url
description
state {
id
name
type
}
project {
id
name
}
attachments {
nodes {
id
title
url
sourceType
}
}
}
}Use this before changing issue state when you need the exact stateId:
query IssueTeamStates($id: String!) {
issue(id: $id) {
id
team {
id
key
name
states {
nodes {
id
name
type
}
}
}
}
}Use commentUpdate through linear_graphql:
mutation UpdateComment($id: String!, $body: String!) {
commentUpdate(id: $id, input: { body: $body }) {
success
comment {
id
body
}
}
}Use commentCreate through linear_graphql:
mutation CreateComment($issueId: String!, $body: String!) {
commentCreate(input: { issueId: $issueId, body: $body }) {
success
comment {
id
url
}
}
}Use issueUpdate with the destination stateId:
mutation MoveIssueToState($id: String!, $stateId: String!) {
issueUpdate(id: $id, input: { stateId: $stateId }) {
success
issue {
id
identifier
state {
id
name
}
}
}
}Use the GitHub-specific attachment mutation when linking a PR:
mutation AttachGitHubPR($issueId: String!, $url: String!, $title: String) {
attachmentLinkGitHubPR(
issueId: $issueId
url: $url
title: $title
linkKind: links
) {
success
attachment {
id
title
url
}
}
}If you only need a plain URL attachment and do not care about GitHub-specific link metadata, use:
mutation AttachURL($issueId: String!, $url: String!, $title: String) {
attachmentLinkURL(issueId: $issueId, url: $url, title: $title) {
success
attachment {
id
title
url
}
}
}Use these when the exact field or mutation shape is unclear:
query QueryFields {
__type(name: "Query") {
fields {
name
}
}
}query IssueFieldArgs {
__type(name: "Query") {
fields {
name
args {
name
type {
kind
name
ofType {
kind
name
ofType {
kind
name
}
}
}
}
}
}
}Do this in three steps:
linear_graphql with fileUpload to get uploadUrl, assetUrl, and
any required upload headers.uploadUrl with curl -X PUT and the exact
headers returned by fileUpload.linear_graphql again with commentCreate (or commentUpdate) and
include the resulting assetUrl in the comment body.Useful mutations:
mutation FileUpload(
$filename: String!
$contentType: String!
$size: Int!
$makePublic: Boolean
) {
fileUpload(
filename: $filename
contentType: $contentType
size: $size
makePublic: $makePublic
) {
success
uploadFile {
uploadUrl
assetUrl
headers {
key
value
}
}
}
}linear_graphql for comment edits, uploads, and ad-hoc Linear API
queries.stateId
instead of hardcoding names inside mutations.attachmentLinkGitHubPR over a generic URL attachment when linking a
GitHub PR to a Linear issue.fileUpload; those URLs already carry the needed authorization.4cbe3a9
