Vpn

Purpose

Establish a secure, verified path when access is blocked by geo/IP policy, then resume the blocked workflow safely and audibly.

Primary outcomes:

1. detect and classify block behavior,
2. switch to a valid tunnel path with explicit user consent,
3. verify public IP, region, and DNS safety posture,
4. re-run blocked task with bounded retries,
5. return an auditable connection report.

This is an orchestration skill. It does not guarantee legal access to restricted services.

Required Credentials and Access

Required access:

• valid account/session for selected tunnel path
• local executable for selected path (nordvpn/mullvad/expressvpn or wg or tailscale)

Optional keys:

• MOLTGUARD_API_KEY (if MoltGuard remote detection mode is enabled)
• IPINFO_TOKEN (optional, higher quota geolocation verification)

Preflight:

command -v nordvpn || command -v mullvad || command -v expressvpn || command -v wg || command -v tailscale
echo "$MOLTGUARD_API_KEY" | wc -c
echo "$IPINFO_TOKEN" | wc -c

Mandatory behavior:

• Never fail silently on missing keys/auth.
• Always return MissingAPIKeys and/or MissingCredentials with blocked stages.
• Continue with non-blocked diagnostics and mark output as Partial when needed.

Compliance Gate (Mandatory)

Before any tunnel switch, confirm and record:

• user authorization to modify network routing,
• acknowledgment of legal/terms responsibility,
• stated purpose for geo-switch (testing, parity checks, privacy hardening).

If acknowledgment is missing:

• do not execute switching commands,
• return diagnostics-only output.

Inputs the LM Must Collect First

• blocked_url or blocked_endpoint
• blocked_task_name (example: prediction-market-arbitrage)
• target_region
• tunnel_path (provider-cli, wireguard, tailscale-exit-node)
• provider_or_profile (provider name, WG profile, or exit-node name)
• risk_mode (diagnose-only, switch-and-verify, switch-and-resume)
• kill_switch_required (yes/no)
• max_retries (default: 2)

Do not execute switching before tunnel path and target region are explicit.

Tool Responsibilities

shell-scripting

Use as control plane:

• executable detection,
• connect/disconnect wrappers,
• retry and cleanup logic,
• deterministic logging.

curl-http

Use for protocol-level evidence:

• baseline and post-switch HTTP checks,
• 403/geo-block signature capture,
• header and status comparisons.

wireguard

Use when deterministic profile-based tunnels are required:

• controlled profile activation,
• route and AllowedIPs sanity expectations,
• DNS handling awareness in tunnel config.

tailscale

Use for tailnet and exit-node path:

• tailscale up --exit-node=<node>,
• connectivity validation via tailscale ping/status,
• fast fallback among available exit nodes.

dns

Use for DNS leak and propagation sanity guidance:

• resolver checks,
• authoritative vs cached record reasoning,
• explicit leak-risk interpretation when DNS path remains local.

ipinfo

Use for geo-attestation:

• validate post-switch country/region/ASN,
• compare with baseline,
• provide confidence level for geo-alignment.

moltguard

Use as prompt/tool security guardrail:

• sanitize sensitive prompt/tool content,
• detect prompt-injection patterns in fetched content,
• reduce accidental secret leakage in workflow logs.

Important limitation:

• MoltGuard is not a VPN manager and not a full network leak detector.

Canonical Causal Signal Chain

1. Block Detection

• baseline request to blocked endpoint,
• classify as geo_block, ip_block, auth_block, or other_http_error.

2. Baseline Snapshot

• capture pre-switch public IP, country, and resolver context.

3. Tunnel Path Selection

• choose one path:
  • provider CLI,
  • WireGuard profile,
  • Tailscale exit node.
• verify binary/auth/profile availability before connect.

4. Tunnel Activation

• connect selected path,
• confirm session state from tool output,
• enforce kill-switch preference if available.

5. Geo and IP Verification

• compare pre/post public IP,
• verify target country best-effort (ipinfo.io + optional token),
• record confidence if country mismatches.

6. DNS Safety Check

• check resolver behavior and detect obvious DNS bypass patterns,
• flag risk if DNS appears untunneled in full-tunnel expectation.

7. Access Retest

• retry blocked endpoint,
• compare HTTP status/content signatures against baseline.

8. Task Resumption

• if retest passes, resume blocked workflow automatically (switch-and-resume mode),
• otherwise rotate endpoint/profile once within retry budget and stop with evidence.

Suggested verification commands:

curl -s ifconfig.me
curl -s https://ipinfo.io/json
curl -I "${BLOCKED_URL}"

Leak and Safety Checks

Minimum checks before success:

• public IP changed,
• target country aligned (or deviation explicitly explained),
• endpoint moved from blocked to reachable/expected-auth state,
• DNS path does not contradict tunnel expectations,
• no unresolved high-risk MoltGuard warning (if enabled).

If kill-switch is required but not supported/verified:

• return Needs Review and avoid high-risk task resumption.

Output Contract

Always return:

• BlockDiagnosis

  • block type
  • baseline HTTP evidence

• TunnelPath

  • selected path and rationale
  • provider/profile/exit node

• TunnelStatus

  • connect state
  • pre/post IP
  • target region match

• DNSSafety

  • resolver observation
  • leak risk assessment (low|medium|high)

• SecurityStatus

  • MoltGuard mode (enabled, gateway-only, disabled)
  • unresolved warnings

• AccessRetest

  • post-switch result
  • improvement vs baseline

• TaskResumption

  • resumed or blocked
  • reason

• NextActions

  • exact commands or account steps for unresolved blockers

Quality Gates

Before final output, verify:

• diagnosis is evidence-based,
• pre/post network evidence is present,
• retry count respected,
• missing credentials/keys clearly disclosed,
• provider/path limitations explicitly stated.

If any gate fails, return Needs Revision with concrete missing checks.

Failure Handling

• Missing tunnel binary/profile: return MissingCredentials with concrete install/profile steps.
• Missing VPN account/auth session: return MissingCredentials, skip switching stage.
• Missing MOLTGUARD_API_KEY in detection mode: return MissingAPIKeys, continue with gateway-only or disabled mode.
• Tunnel connected but geo mismatch persists: one bounded retry with different endpoint/profile, then stop.
• Endpoint still blocked after retry: return full evidence bundle and manual-decision path.

Guardrails

• Never claim legal or terms compliance on behalf of user.
• Never claim secure state without pre/post verification.
• Never unbounded-loop region hopping.
• Never hide ambiguous or failed access states.
