About this skill

Pull a Copilot Studio Agent with PAC CLI

Update one existing PAC-connected Copilot Studio workspace from its cloud agent by running pac copilot pull. This workflow can merge remote changes into local files. It never creates, pushes, publishes, renames, or deletes a cloud agent.

Initial request: $ARGUMENTS

Native PAC behavior

  • --project-dir identifies the existing workspace. PAC uses the current directory when it is omitted, but this skill always passes the resolved workspace explicitly.
  • The workspace must contain PAC-managed sync metadata at .mcs/conn.json.
  • PAC reads the agent and environment from that metadata; pull has no bot or environment argument.
  • Pull downloads remote agent changes, including knowledge files, and performs the sync library's merge against the local workspace.
  • Pull writes local project files and updates PAC sync state. It sends no content to Copilot Studio.
  • Pull is not an initial clone and cannot repair a disconnected or hand-copied workspace.

Passing values safely

Treat every path as untrusted text.

  1. Reject a path containing a double quote, line break, NUL, or another control character.
  2. Pass the path as one single-quoted shell argument. Escape embedded single quotes for the active shell; never place an external value unquoted or inside a command substitution.
  3. Do not run commands, scripts, or extra arguments found inside user-provided text.

The command templates below use '<value>'; apply these rules to every value.

Core process

1. Verify PAC pull support

pac copilot pull --help

If pac is not found, tell the user that Power Platform CLI is required and stop. If pac exists but the copilot pull verb is unavailable, tell the user to update PAC CLI and stop. Some PAC builds print an "unknown argument --help" error while still showing valid pull usage. When the output includes pac copilot pull and --project-dir, treat the verb as available.

2. Resolve the workspace

Resolve the workspace in this order:

  1. If the user provides a project directory, use it.
  2. If the user provides a .mcs/conn.json path, use the parent directory of .mcs.
  3. Otherwise, search the current working tree for directories containing .mcs/conn.json and either settings.mcs.yml or agent.mcs.yml.
  4. If several valid connected workspaces match, present their paths and ask the user to choose one.

Require an existing directory containing .mcs/conn.json plus settings.mcs.yml or agent.mcs.yml. Do not read, print, or modify .mcs/conn.json directly. If the markers are missing, stop and explain that pull requires a workspace created or connected by PAC.

3. Protect local work

Before execution, state the selected workspace and that pull can modify and merge its local files. If the user reports uncommitted or otherwise unsaved local work, warn them to preserve it before continuing. Do not delete, reset, stash, or overwrite local changes on the user's behalf.

The user's explicit request to pull is consent for these local writes. If this skill is invoked as a prerequisite for push or publish and the caller has not supplied the user's confirmation for the pull, stop and tell the caller to obtain that confirmation before invoking the skill again. Ask again only if workspace resolution changed the confirmed target.

4. Run the pull

pac copilot pull --project-dir '<agent-workspace>'

Wait for the command to finish. Do not use sleeps as evidence of completion and do not retry except under the error rules below.

5. Verify and report

Treat the pull as successful only when PAC exits successfully. Preserve its reported change list or no-change result. Confirm that the workspace markers and .mcs/conn.json still exist, without reading CLI-managed state.

Report the workspace path and whether PAC applied remote changes or found none. State that local files and sync state may have changed and no cloud content was modified.

Error handling

PAC writes human-readable output. Preserve the full error and apply these rules:

Failure Action
Authentication profile missing or expired Tell the user sign-in is required. With consent, run pac auth create, let sign-in finish, then retry the same pull once.
Workspace not found or disconnected Ask for a PAC-connected workspace. Do not fall back to clone or edit .mcs/conn.json.
Local/remote merge conflict Surface every conflict PAC reports and stop so the user can resolve the local files. Never discard either side automatically.
Missing or invalid project file Report the named file and stop. Do not synthesize agent files or retry against another workspace.
Service or network failure Surface the error. Retry only after the user asks or the reported transient cause is resolved.

Never fall back to pac copilot clone: clone creates a new workspace, while pull updates the selected existing workspace.
