Agent Guardrails

Run this workflow from Codex. Behavioral guardrails for Claude Code agents. Nine battle-tested rules (no-guessing, no-stalling, no-preference-asking, no-false-completion, no-skipping, no-dismissing, no-cosmetic, no-caveats, no-flagging) enforced via a Stop hook bash script. Includes analyze, install, test, and update skills for data-driven tuning.

Run this workflow from Codex. Stop hooks that terminate a Claude Code session when the agent's final message contains a kill phrase. Two scripts: single-kill (ends Claude) and double-kill (ends Claude plus the terminal shell that launched it), each bound to its own phrase. Installs at local (project) or global (user) scope; scripts require LOCAL or GLOBAL arg and exit 1 if missing. Contains-match (robust to model preambles), case-sensitivity configurable, and a kill path that walks the process tree to the owning claude (and, for double-kill, the top-most shell ancestor) and never signals pid <= 2. Install, remove, update, info, and whendone skills via a router; composes safely with existing Stop hooks.

Roll Claude Code out to a team with guardrails you can check. Four deterministic stdlib scripts: a settings linter that reads shared, local, user and managed settings together (array merge, deny-ask-allow order) and blocks blanket shell allows, pre-approved destructive commands and committed credentials; an MCP and plugin inventory that blocks anything missing from your approved list or holding a literal secret, and flags unpinned or plain-http servers; a CLAUDE.md layering audit that resolves every layer and @import and flags broken imports, contradictions, secrets and resident size; and a privacy-safe adoption tracker that turns local session files into counts only and classifies the rollout as PILOT, SPREADING, EMBEDDED or STALLED. Ships cs-claude-code-rollout agent, /cs-claude-rollout and /cs-claude-settings-lint commands, 3 references, a baseline managed-settings policy and a four-phase rollout plan.
