building-autonomous-team-update

building-autonomous-team-update is a skill for Claude Code, Codex from fengjunhui31/building-autonomous-team. It costs 28 tokens per session (2,250 once invoked), scanned C, original, MIT.

A tool for updating an existing autonomous coding team to a newer plugin version while keeping its project-specific changes.

In plain words
What is it for?
Checking the current team and plugin versions, updating agent roles and workflow rules, and moving team state to the newer setup.
Why use it?
It avoids rebuilding the team from scratch and helps preserve custom settings during a version upgrade.

Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

building-autonomous-team-update scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Autonomous Team Update Skill (v2.0)

Overview

Update agent definitions and workflow rules to latest version without reinitializing.

v2.0 major changes:

  • 9 persistent agents → 2 persistent + dynamic
  • Local state files → GitHub-only state
  • New roles: facilitator (merged 4), mission-analyst (new)
  • Removed roles: discussion-facilitator, consensus-manager, spec-writer, merge-manager, env-manager

Step 0: Pre-check

0.1 Check Team Exists

ls .autonomous-team/workflow.md .claude/agents/ 2>/dev/null || echo "NO_TEAM"

If NO_TEAM: Block. Run /building-autonomous-team to initialize first.

0.2 Check Remote Plugin Version

Before anything else, check if the installed plugin is up-to-date with the remote marketplace:

# Current installed plugin version
LOCAL_PLUGIN_VERSION=$(cat ${CLAUDE_PLUGIN_ROOT}/.claude-plugin/plugin.json | jq -r '.version')

# Fetch latest version from remote marketplace (GitHub)
REMOTE_PLUGIN_VERSION=$(gh api repos/fengjunhui/building-autonomous-team/contents/.claude-plugin/marketplace.json \
  --jq '.content' | base64 -d | jq -r '.plugins[0].version')

echo "Local plugin: $LOCAL_PLUGIN_VERSION | Remote: $REMOTE_PLUGIN_VERSION"

If REMOTE > LOCAL (plugin itself needs update):

⚠️ Plugin update available: v{LOCAL} → v{REMOTE}

Updating plugin first...
# Clear cache and reinstall
rm -rf ~/.claude/plugins/cache/building-autonomous-team
claude plugin uninstall building-autonomous-team@building-autonomous-team
claude plugin install building-autonomous-team@building-autonomous-team

After plugin update completes, inform user:

✅ Plugin updated to v{REMOTE}.
Please restart this session for the new plugin to take effect,
then run `/building-autonomous-team` again to update the team.

STOP HERE — the new plugin version may contain different update logic. User must restart session.

If REMOTE == LOCAL (plugin is current): Continue to Step 0.3.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
