XGuard Policy Manager

Use this skill to manage XGuard policy options against the orchestrator's /v1/manager/xguard/* admin endpoints.

Each label's policy is the natural-language prompt text + threshold + action that the orchestrator applies when evaluating an XGuard call. See docs/features/scanner-prompt-tuning.md for how this fits into the scanner refinement lifecycle. Phase 4 (refine policy) is the typical use of this skill: fetch the current options, edit a policy, PUT the new version, then track FP/FN rates against the new policyHash in the audit log.

Setup

The skill reads ORCHESTRATOR_ENDPOINT and ORCHESTRATOR_ACCESS_TOKEN from the project .env (or .claude/skills/xguard-manager/.env if you want skill-specific overrides). No additional setup beyond having those env vars set.

Commands

node .claude/skills/xguard-manager/manage.mjs <command> [args] [options]

Command	Description
get <mode>	GET current options for the mode (text or prompt)
defaults <mode>	GET hardcoded defaults baked into the orchestrator
put <mode>	PUT new options for the mode (requires --writable + --file)
reset <mode>	POST reset back to defaults (requires --writable)
export	GET bulk export across all modes
import	PUT bulk import across all modes (requires --writable + --file)

Options

Flag	Description
--writable	Allow destructive operations (PUT / POST). Required for put, reset, import.
--file <path>, -f <path>	Read the request body (JSON) from a file. Required for put and import.
--output <path>, -o <path>	Save response to a file (instead of printing to stdout).
--quiet, -q	Only print the response body, no connection headers.
--timeout <s>, -t <s>	Request timeout in seconds (default: 30).

Examples

# Inspect current prompt-mode options
node .claude/skills/xguard-manager/manage.mjs get prompt

# Save the current prompt-mode options to a file you can edit
node .claude/skills/xguard-manager/manage.mjs get prompt -o /tmp/prompt-policies.json

# See what the defaults look like (useful for scaffolding a new label)
node .claude/skills/xguard-manager/manage.mjs defaults prompt

# Ship an edited policy
node .claude/skills/xguard-manager/manage.mjs put prompt -f /tmp/prompt-policies.json --writable

# Wipe prompt-mode policies back to defaults (destructive)
node .claude/skills/xguard-manager/manage.mjs reset prompt --writable

# Back up the entire policy registry before a risky edit
node .claude/skills/xguard-manager/manage.mjs export -o /tmp/xguard-backup.json

# Restore from a backup
node .claude/skills/xguard-manager/manage.mjs import -f /tmp/xguard-backup.json --writable

Safety

1. Read-only by default: get, defaults, and export always work without --writable.
2. Destructive operations require explicit --writable: put, reset, and import change orchestrator state and refuse to run without the flag.
3. Always ask the user before using --writable: policy changes are global — every subsequent scan will use the new policy text. Confirm the intent before running.
4. Back up before editing: run export -o backup.json before any non-trivial change so you can import to restore if needed.

Typical workflow for refining a policy (Phase 4)

# 1. Snapshot current state for safe rollback
node .claude/skills/xguard-manager/manage.mjs export -o /tmp/xguard-backup-$(date +%Y%m%d).json

# 2. Pull the current options for the mode you're editing
node .claude/skills/xguard-manager/manage.mjs get prompt -o /tmp/prompt-current.json

# 3. Edit /tmp/prompt-current.json with the refined policy text

# 4. Ship it (after user confirms)
node .claude/skills/xguard-manager/manage.mjs put prompt -f /tmp/prompt-current.json --writable

# 5. Track FP/FN rate of new policyHash via the audit log + focused review

Why this is separate from the postgres-query / clickhouse-query skills

Those query the audit data (verdicts, scores, matched terms). This skill manages the policy itself — the prompt text the orchestrator hands to XGuard. A typical tuning loop uses both: query data to identify FP patterns, edit the policy here, then re-query after new scans land under the new policyHash.
