name	lisa-github-project-v2
description	Shared GitHub ProjectV2 coordination utility. Every GitHub writer or linked pull request flow that needs Project membership MUST delegate through this skill instead of inlining GraphQL. Resolves the configured ProjectV2 id from `github.projects.v2`, validates namespace + access, adds Issue or Pull Request node ids to the Project, optionally updates Project field values, and returns exact failures with best-effort vs required-mode branching.

GitHub ProjectV2: $ARGUMENTS

Single chokepoint for GitHub ProjectV2 coordination. Caller skills (github-write-prd, github-write-issue, git-submit-pr, later linked-PR flows, later doctor/setup checks) MUST go through this skill rather than duplicating gh api graphql calls.

The utility never invents policy. It applies the config + validation contract already defined in config-resolution:

• github.projects.v2 absent → coordination is disabled; callers keep repository-local writes.
• required: false → Project failures are warning-level, and the underlying issue / PR write remains the durable success.
• required: true → the same Project failures are blocking errors.

Invocation contract

The caller passes exactly one operation plus its arguments:

operation: resolve-project
operation: add-item         content_node_id: <issue-or-pr-node-id>
operation: ensure-item      content_node_id: <issue-or-pr-node-id>
operation: update-fields    item_id: <project-item-id> values: [{ field: "Status", option: "In Progress" }]
operation: add-and-update   content_node_id: <issue-or-pr-node-id> values: [{ field: "Repository", text: "frontend-v2" }]

Argument rules:

• content_node_id is the opaque GraphQL node id of a real GitHub Issue or Pull Request.
• item_id is the opaque Project item id returned by add-item / ensure-item.
• values is optional for update-fields / add-and-update. Omit it when membership alone is sufficient.

Return shape:

enabled: true | false
required: true | false
outcome: disabled | resolved | added | reused | updated | warning | blocked
project_id: "<opaque-project-id>"
item_id: "<opaque-project-item-id>"
warnings:
  - "<warning text>"
error:
  code: "<stable-code>"
  message: "<exact gh / GraphQL failure>"
  remediation: "<next step>"

error.message MUST preserve the exact GitHub failure text (permission error, missing project, field mismatch, duplicate-content response, etc.). Do not collapse failures into generic "Project update failed."

Workflow

Step 1 — Resolve and validate config

Read config in local-overrides-first order:

read_cfg() {
  local path="$1"
  local lv gv
  lv=$(jq -r "$path // empty" .lisa.config.local.json 2>/dev/null)
  gv=$(jq -r "$path // empty" .lisa.config.json 2>/dev/null)
  echo "${lv:-$gv}"
}

ORG=$(read_cfg '.github.org')
REPO=$(read_cfg '.github.repo')
OWNER_KIND=$(read_cfg '.github.projects.v2.owner.kind')
OWNER_SLUG=$(read_cfg '.github.projects.v2.owner.slug')
PROJECT_NUMBER=$(read_cfg '.github.projects.v2.number')
REQUIRED=$(read_cfg '.github.projects.v2.required')
REQUIRED=${REQUIRED:-false}

If the github.projects.v2 block is absent or incomplete, return:

enabled: false
required: false
outcome: disabled

That is a clean no-op for best-effort callers; they continue the repository-local write path.

When the block is present:

1. Require github.org, github.repo, owner.kind, owner.slug, and number.
2. Enforce the v1 namespace rule: owner.slug MUST equal github.org.
3. Enforce supported owner kinds only: organization or user.
4. Confirm gh auth status succeeds before any GraphQL call.

Namespace mismatch is never silent. It returns a configuration failure with exact remediation:

enabled: true
required: <required>
outcome: warning | blocked
error:
  code: project_namespace_mismatch
  message: "github.projects.v2.owner.slug must match github.org in v1"
  remediation: "Use a Project owned by <github.org> or remove github.projects.v2."

Step 2 — Resolve the Project id

Resolve the human-facing owner + number to the opaque ProjectV2 id:

gh api graphql -f query='
query($login:String!,$number:Int!){
  organization(login:$login){ projectV2(number:$number){ id title number url } }
  user(login:$login){ projectV2(number:$number){ id title number url } }
}' -F login="$OWNER_SLUG" -F number="$PROJECT_NUMBER"

Pick the branch matching owner.kind. If the Project is missing, inaccessible, or the authenticated identity cannot read it, preserve the exact GraphQL failure text in error.message.

Successful resolution returns:

enabled: true
required: <required>
outcome: resolved
project_id: "<opaque-project-id>"

Step 3 — Add an Issue or Pull Request to the Project

For add-item, ensure-item, or add-and-update, first resolve the Project id, then add the provided Issue / Pull Request node id:

gh api graphql -f query='
mutation($projectId:ID!,$contentId:ID!){
  addProjectV2ItemById(input:{projectId:$projectId contentId:$contentId}){
    item { id }
  }
}' -F projectId="$PROJECT_ID" -F contentId="$CONTENT_NODE_ID"

Behavior:

• add-item expects the membership write to succeed and returns outcome: added.
• ensure-item is idempotent. If GitHub reports the content is already in the Project, return outcome: reused and surface the existing membership as a success, not a failure.
• add-and-update adds first, then continues into Step 4.

When GitHub returns a duplicate-membership or already-present response, ensure-item MUST branch idempotently rather than rethrowing.

Step 4 — Optionally update Project fields

If values are provided, apply them in order to the Project item returned from Step 3. Support the common field types callers need first:

• single-select option by field name + option name
• text field by field name + text value
• iteration field by field name + iteration title
• date field by field name + ISO date

The utility resolves the Project's fields first, then performs the correct GraphQL mutation for the typed value. Missing field names or option names are exact failures; never silently skip them.

Example shape:

operation: add-and-update
content_node_id: <node-id>
values:
  - { field: "Status", option: "In Progress" }
  - { field: "Repository", text: "lisa" }

Successful field updates return outcome: updated with both project_id and item_id.

Step 5 — Required vs best-effort branching

Every failure after config detection branches on required:

• required: false → return outcome: warning, preserve the exact error, and let the caller keep the underlying issue / PR write as the durable success.
• required: true → return outcome: blocked with the same exact error, causing the caller to fail the write before claiming Project coordination succeeded.

This means the exact same GitHub failure can surface in two different severities without changing its message:

enabled: true
required: false
outcome: warning
error:
  code: project_access_denied
  message: "Resource not accessible by integration"
  remediation: "Grant the token Project read/write access or disable github.projects.v2."

enabled: true
required: true
outcome: blocked
error:
  code: project_access_denied
  message: "Resource not accessible by integration"
  remediation: "Grant the token Project read/write access or disable github.projects.v2."

Rules

• Never create draft issues here. This utility coordinates real Issues / Pull Requests only.
• Never replace repository-local lifecycle truth with Project fields. Project membership is a coordination view layered on top.
• Never hide the original GitHub failure text.
• Never treat duplicate membership as an error for ensure-item.
• Never mutate issue / PR labels, comments, or body from this skill. Writers own those surfaces.
• All GitHub ProjectV2 membership and field writes go through this skill so future GraphQL changes are made in one place.
