unity-volume

Before calling any skill in this module: if you are about to call a skill with parameters guessed from its name or description, STOP — read this file (or fetch its schema via GET /skills/recommend?includeSchema=true) first. If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.

Triggers

• Setting up volumes
• Creating or loading a VolumeProfile
• Adding global/local volumes
• Set up Volume, create or load VolumeProfile, add global/local Volume to the scene

Volume Skills

Shared SRP Volume framework skills for Unity 2022.3+ — works in URP and HDRP via SRP Core.

Operating Mode

• Query skills (volume_list_component_types, volume_get_component) are SkillMode.SemiAuto — they run in all three modes without grant.
• Mutating skills (volume_profile_create, volume_create, volume_set_profile, volume_add_component, volume_set_parameter, volume_set_parameter_batch) are SkillMode.FullAuto — under Approval they need user grant (grant triggers one server-side execute returning the result); under Auto / Bypass they execute directly.
• volume_remove_component carries SkillOperation.Delete and is auto-forbidden in Approval / Auto modes (NeverInSemi). Only Bypass or the user-managed Allowlist can run it.

SRP Package Stub

This module is compiled against com.unity.render-pipelines.core (SRP_CORE). When neither URP nor HDRP is installed (no SRP Core), every skill returns a stub { error: "Scriptable Render Pipeline Core package … is not installed." } (RenderPipelineSkillsCommon.NoSRP()). The stub is a diagnostic payload, not a permission denial — it does not require grant and is not treated as NeverInSemi. Inspect project_get_render_pipeline first when you see this error.

Guardrails

Routing:

• For Volume container/profile CRUD: use this module
• For high-level modern post-processing effects like Bloom/DOF/Tonemapping: prefer postprocess

Runtime-first rules:

• Always call volume_list_component_types before assuming a component type exists on the active pipeline
• Use volume_get_component after add/create to inspect the actual parameter names before writing values
• Prefer exact parameter names returned by the live component data instead of guessing from memory
• volume_set_parameter_batch expects items to be a JSON array string
