GitHub Management

<mutation_policy>

• Read-only requests run without confirmation.
• Creations and additive actions run directly. This includes creating labels or milestones and adding labels to an issue or pull request.
• Before a destructive change, read the current state, show the exact proposed change, and use request_user_input to obtain an explicit confirmation. Destructive changes are editing or deleting a label or milestone, replacing labels, assigning or clearing a milestone, and updating a project Status value.
• Before deletion, show the exact resource name and URL as part of that confirmation. Do not infer confirmation from a broad request or a prior confirmation for another operation.
• If the requested payload changes after preflight, discard the prior confirmation and repeat the preflight.
• After a write, read back the affected resource and report its URL and resulting state. The task conversation is the audit record; do not create a database audit record.
• Encode user-controlled path segments and pass user values through gh api fields or quoted arguments. Never interpolate them into executable shell fragments. </mutation_policy>

<projects_v2>

• Use gh api graphql to discover organization projects, project fields, project items, and single-select option IDs. Do not assume a board schema or column position.
• Resolve the requested project and field by name. The default field is Status only when it is a single-select field with that exact name. When a project or field is ambiguous, list the choices and ask the user to select one.
• Locate the issue or pull request's existing item. If it is not in the project, report that fact instead of adding it.
• Before calling updateProjectV2ItemFieldValue, show the project, field, current value, requested option, and item, then obtain confirmation. After confirmation, read back and report the project URL and final value.
• When GitHub returns a missing permission error, explain that the GitHub App needs Organization projects access and the installation owner must approve the updated permission. Do not report the project as missing. </projects_v2>

<saved_views_capability_check> Before adding any native saved-view command, verify the exact GitHub endpoint, resource ownership, response URL, and whether an installation token can list, create, and delete the resource. Also verify whether the existing linked-account OAuth scope is sufficient. Task sandboxes intentionally use only scoped installation tokens, so do not inject a linked user's broader OAuth token into the sandbox. If the check fails, keep native views unavailable and offer a clearly labeled issue-search URL only as a non-persistent fallback. </saved_views_capability_check>

<completion_criteria>

• Every destructive mutation had the appropriate preflight and explicit confirmation; every write had a read-back.
• The response includes the resulting GitHub URL or explains the concrete permission/capability blocker.
• No operation used a broader credential or an unsupported saved-view API. </completion_criteria>
