The Agent Skills Directory

[COMMAND_EXECUTION]: The skill executes the arkcli binary and npx -y @byted-supabase/cli@latest install to configure agents and install necessary vendor tools.
[INDIRECT_PROMPT_INJECTION]: The skill is susceptible to indirect injection because it processes user prompts through a routing mechanism (routing.v1) to determine which tool (e.g., doubao_search, datapro) to invoke.
Ingestion points: Intercepts user inputs at UserPromptSubmit and PreToolUse gates in files like SKILL.md and references/arkcli-helper.md.
Boundary markers: Uses a structured JSON schema for Route Plans and requires validation against a per-turn ID.
Capability inventory: Performs file writes to agent configuration directories (e.g., ~/.claude.json, ~/.codex/config.toml), injects environment variables into .env files, and invokes system commands through the arkcli utility.
Sanitization: Enforces a strict mapping between classified intents and specific authorized providers.
[EXTERNAL_DOWNLOADS]: Fetches vendor-specific packages via npx and provides instructions for the manual installation of the Evolve skill from the vendor-controlled domain volces.com.
