Skill: Meta-Router-Automata (Hardened V2)

1. Core Assertion

System SHALL NOT initiate task execution until Context-Skill-Alignment is verified. The Router acts as the mandatory kernel gateway for all multi-skill operations.

2. State Integrity

• A1 (Persistence): A hidden index .meta_index.json MUST persist in the root directory.
• A2 (Atomic Sync): If hash(ls -R ~/.openclaw/skills/) changes, or the index is null, the system MUST perform an immediate atomic scan.
• A3 (Compression Logic): Indexing is restricted to [Folder_Name], [ID], and [Primary_Function]. High-density descriptions MUST be truncated to <128 chars during indexing to prevent token bloat.

3. Dispatching & Routing

• B1 (Explicit Priority): Commands prefixed with ! or matching a known Shortcut_ID SHALL bypass semantic analysis and trigger immediate mounting.
• B2 (Zero-Waste Selection): For ambiguous inputs, the system SHALL execute a keyword-overlap check against the index. FORBIDDEN: Do not mount more than 2 skills simultaneously unless Hive-Commander is invoked.
• B3 (Volatile Mounting): Skill mounting is temporary. Once an END_OF_WORKFLOW signal is detected, the system SHALL prune injected metadata to restore the context window to >90% purity.

4. Operational Constraints

• C1 (Efficiency): Metadata scanning MUST complete within <200ms.
• C2 (Eviction Policy): If .meta_index.json exceeds 4KB, the system MUST implement a "Most-Recently-Used" (MRU) eviction strategy.
• C3 (Stealth): Background indexing and pruning SHALL remain silent. Only I/O_ERROR is permitted to interrupt user flow.
