bug: security-review-all team agents stuck (in-process), blocking TeamDelete

[louisgv]

Context

Security review cycle (2026-04-12 ~11:30 UTC) spawned 4 teammates:

• branch-cleaner (Sonnet)
• issue-checker (Haiku)
• shell-scanner (Sonnet)
• code-scanner (Sonnet)

All 4 agents received shutdown requests and completed their tasks (TaskOutput shows status: completed), but they remain registered as active in the team config.

Error

TeamDelete failed: Cannot cleanup team with 4 active member(s): branch-cleaner, issue-checker, shell-scanner, code-scanner.

Pattern

This is the SAME pattern as issues #3277, #3278, #3279, #3280, #3281. In-process teammates complete but don't properly unregister from team membership.

Impact

• Cannot clean up team resources
• Team directory persists: /root/.claude/teams/fancy-swimming-wand/
• Task directory persists: /root/.claude/tasks/fancy-swimming-wand/

Reproduction

1. TeamCreate with team_name
2. Spawn 4+ in-process teammates
3. Send shutdown requests
4. Wait for completion (TaskOutput shows completed)
5. Attempt TeamDelete → fails with active members error

Acknowledged. This is the same stuck-agent/TeamDelete pattern seen in #3281, #3279, #3278, #3277, #3268, #3267, #3263, #3262, #3249, #3244, and #3154 — agents complete their work but remain registered as active, preventing TeamDelete from cleaning up the team.

The root cause is in the team orchestration layer (.claude/skills/setup-agent-team/), which is off-limits for automated refactoring. No automated fix is possible. This requires manual maintainer intervention.

Security Triage

Category: Infrastructure issue (off-limits: .claude/skills/setup-agent-team/)

Finding: This is a recurring pattern of team agents becoming stuck in-process and blocking TeamDelete. The root cause is in agent team orchestration infrastructure (off-limits for automated fixes).

Status: Escalated to manual maintainer review.

PR #3282 (merged 2026-04-12) directly addresses the TeamDelete failure when agents are stuck in-process. This fix handles the case where agents complete work but remain registered as active — TeamDelete now force-proceeds instead of blocking. This should resolve this issue and the entire cluster of related reports (#3280, #3279, #3278, #3277, #3268, #3267, #3263, #3262, #3259, #3249, #3244).

Additionally, PR #3265 (merged 2026-04-11) adds max-retry force-proceed to prevent the infinite shutdown loop described in #3154.
