The Agent Skills Directory

[DYNAMIC_EXECUTION]: The skill provides templates for using ae_set_expression and ae_run_jsx to inject and execute code at runtime. Specifically, ae_run_jsx allows for the execution of arbitrary ExtendScript code to manipulate After Effects project items and properties.
[INDIRECT_PROMPT_INJECTION]: The skill is designed to ingest and process data from external sources and project metadata.
Ingestion points: Loads data from external files via footage("data.csv") and retrieves context from user-defined layer names (e.g., thisComp.layer("Name")) and markers.
Boundary markers: No specific delimiters or boundary markers are instructed for the agent to use when interpolating content from these untrusted data sources.
Capability inventory: The skill utilizes powerful bridge tools including ae_set_expression, ae_run_jsx, and ae_menu_command (all documented in SKILL.md) which can modify project state or execute scripts.
Sanitization: There is no evidence of input validation or sanitization for data retrieved from CSV files or project metadata before it is used in expression logic.
[COMMAND_EXECUTION]: The skill uses ae_menu_command to trigger application-level menu actions (such as "Convert Expression to Keyframes") and ae_run_jsx to execute host-side scripts.
