Error message
list agent skills: %w
What it means
Wrapped error returned when `multica agent skills <id>` (list) fails to GET `/api/agents/{id}/skills`. The wrapped cause is typically 404 for an unknown agent id, 401/403 for auth/permission issues, or a connection failure to the multica server.

Solutions
- Confirm the agent id with `multica agent list` and retry
- Verify the server is running and API URL/token env vars are correct
- Treat 403 as a workspace-permission issue — check membership/role
- In automation, catch 404 and skip/prune the dead agent id
Example fix
# before multica agent skills agt_x # Error: list agent skills: 404: agent not found # after multica agent list multica agent skills agt_1
Defensive patterns
Strategy: try-catch
Validate before calling
multica agent get "$AGENT_ID" >/dev/null 2>&1 || { echo 'agent not found'; exit 0; }
multica agent skills "$AGENT_ID" Try / catch
skills, err := fetchAgentSkills(id)
if err != nil {
if isNotFound(err) { return nil }
return fmt.Errorf("list agent skills: %w", err)
} Prevention
- Cache agent ids from `agent list` and prune 404s in automation
- Use --output json when feeding results to scripts
- Check server health before batch listing operations
When it happens
Trigger: Listing skills of a mistyped/deleted agent id, or when the server is unreachable or the token is invalid/expired.
Common situations: Auditing agent configurations in scripts where agent ids have churned; stale shell history; CLI pointed at a different workspace than expected.
