Earl prevents prompt-injection and secret leakage by routing API calls, database queries, and shell commands through reviewed HCL templates instead of exposing raw endpoints or credentials to an LLM.
Use Earl to search for a template matching "list github pull requests" and call the matched provider.command with the needed parameters.
High-intent search queries and answers about installing and using this skill.
Preventing prompt injection during API calls or shell commands requires routing agent requests through reviewed HCL templates, which constrains the agent to deterministic, pre-approved execution paths. This approach prevents the LLM from seeing raw endpoints or modifying command logic.
Keeping secrets out of LLM context during CLI automation is achieved by reading credentials directly from the OS keychain at execution time. The templates access required secrets internally without exposing them to the agent's prompt context.
Routing database queries through MCP endpoints safely is done by mapping query intents to a matched provider.command within an HCL template. The template enforces strict flag ordering and returns structured JSON results for deterministic consumption.
Yes, the Earl template system requires explicit confirmation for write-mode operations to prevent unauthorized modifications. This safety mechanism enforces strict flag ordering and approval checks before executing any state-changing API or shell command.
Yes, you can use HCL templates to search installed provider templates by intent and execute the matched provider.command with required parameters. This discovery process maps natural language intents to specific API calls, database queries, or shell commands.
