Add optional HOL Guard pre-execution boundary for agent-run Temporal operations

Problem

AGENT-PERMISSIONS.md correctly calls out that the skill's approval guidance is behavior rather than a security boundary, and its Tier 3 section recommends a pre-execution hook for destructive temporal / tcld commands. The current hand-written regex example is intentionally described as a speed bump because aliases, shell indirection, and wrappers can bypass text matching.

Would you be open to adding an optional maintained HOL Guard path alongside that Tier 3 example?

Proposed scope

Keep Temporal's existing credential scoping, namespace delete protection, native confirmations, audit logs, and blast-radius guidance authoritative. Add a short optional section that directly installs and invokes HOL Guard on a supported local coding-agent harness before state-changing Temporal work, for example:

pipx install hol-guard
hol-guard detect --json
hol-guard install <detected-harness>
hol-guard run <detected-harness>

The accepted guidance should be explicit about the boundary:

• HOL Guard protects the supported local agent harness; it does not run inside Temporal Cloud or the Temporal server.
• Temporal credentials, server-side permissions/delete protection, and native CLI safety checks remain authoritative.
• Do not claim dedicated classification for every temporal / tcld command unless that behavior is independently verified.
• Guard deny/review/error/unavailable states must not be bypassed by relaunching an unprotected agent for the same mutation.
• The existing handcrafted hook can remain as the transparent Temporal-specific example; HOL Guard is the optional reusable runtime boundary for users who already run supported coding agents.

If this placement fits, I can follow with the smallest repository-native docs/skill change and whatever validation you prefer.

Affiliation: I maintain HOL Guard / Hashgraph Online. AI assistance was used to prepare this issue; I checked the proposed boundary against the current Temporal Ops Skill documentation and the maintained HOL Guard setup flow.

Start with AGENT-PERMISSIONS.md, especially the Tier 3 section and its existing handcrafted hook example. Add an optional HOL Guard path that preserves Temporal's authoritative safeguards and clearly states the local harness boundary, then run the repository's documented validation if available and confirm the guidance covers unavailable, denied, review, and error states without bypasses.
